Session and Vector object
Hi,
I would like to store a instance of Vector in HttpSession.
My question is: should I save the concrete vector from Session object before manipulation with it (adding elements, ...)?
Or can I manipulate with vector data still saved in Session object? I yes, please, can you show me sample code?
Thanks a lot.

Sure you could compress it... you could use the classes in java.util.zip, and use an ObjectOutputStream plus a ZipOutputStream plus a ByteArrayOutputStream (I think), using zip compression to convert your Vector into an array of bytes, and then do the reverse when you needed the data uncompressed. Chances are that would compress your data by about 80 or 90%.
Here you would be making the classic tradeoff between memory usage and processing time; I wouldn't do this compression thing until it was clear that it was necessary, though.

Toplink session and UnitOfWork synchronization problem
Dear forum readers,
I am not sure i fully understand the way how toplink deals with caching. To me it seems, that i got some pretty scary results, which i am not sure how to interpret and to work around them.
The following code snippet is part of a unit test:
>>>>>>>>>>>> snip >>>>>>>>>>>>>>>
1 public void test2() {
2
3 UnitOfWork uow = (UnitOfWork) SessionManager.getSessionManager().getSession().getUnitOfWork();
4 Justitiabele justitiabele = findJustitiabele("findById", Justitiabele.class, new Long(551));
5 ((JustitiabeleIdentiteit) justitiabele.getJustitiabeleIdentiteiten().iterator().next()).setMeisjesnaam("Kettner10");
6 Justitiabele tmp = (Justitiabele) uow.registerObject(justitiabele);
7 ((JustitiabeleIdentiteit) tmp.getJustitiabeleIdentiteiten().iterator().next()).setMeisjesnaam("Kettner10");
8 uow.commitAndResume();
9 }
10
11 public Justitiabele findJustitiabele(String queryName, Class objectClass, Object param) {
12 SessionWrapper toplinkSessionWrapper = getSession();
13 toplinkSessionWrapper.getClientSession().executeQuery(queryName, objectClass, param);
14 }
>>>>>>>>>>>>>>>> snip <<<<<<<<<<<<<<<<
I am querying a particular object (line 4). Then i make some changes to that object (line 5). Cause the object is not registered in the UnitOfWork these changes shouldn't be persisted. So far so good. To achieve persistency i now register the object, and i make the same modifications to the toplink clone, expecting them after the commit to be persisted in the database.
Contrary to my expectations, the changes were not persisted!!!
Deleting line 5 (the modifications, before registering the object), leads to the desired result.
Somehow the queried object seems to be a direct reference to the (client-) session cache. So when registering the object in the UnitOfWork, the (already modified) backupclone is copied from the session cache to the UnitOfWork. If the same changes are done to the working clone,there are no differences between backup- and working clone and no changes are made in the database.
It gets even better: I tried to query the object again (before line 6) (even with a different UnitOfWork) before modifying it, in order to retrieve the original state of the object, but again i only was able to find the modified object.
If the queried object indeed is a reference to some cache, i cannot understand, why that cache is not read only!!!
Am i doing something wrong ?
Is there a way to work around this problem?
What are the consequences for transaction handling ? What about Isolation, when clients can see each others changes in a kind of writeable shared session???
I try to work around that problem by registering every object, that is queried from the database in the UnitOfWork right after it was queried. This seems to me the only solution, though this is contrary to what the toplink developers guide says, namely, that only objects which are modified should be registered, due to performance reasons.
I would be grateful to any help in understanding and working around this problem.

The object returned from any query on the sessions is the object from the shared cache. Any changes made to this will change the shared cache.
You must acquire a UnitOfWork and register the cached object into the UnitOfWork in order to get an isolated copy that can be modified within a transactional context (UnitOfWork) without other threads seeing these transient changes. The typical approach is to read through the session and register objects involved in a change prior to modifications.

I created a vector and added objects, but the vector is empty
I created an object called a facility, it accepts 2 strings in the creator but stores the data as a string and a float. as you can see from the code below, i have tried to create a vector object to contain facilitys and named it entries. when i add objects to this vector, the vectors size does not change, and i cannot access elements of it via their index. but when i print the vector out i can see the elements? what is going on here. i am very confused. ps, if it helps i havent worked with vectors much before.
FacilitysTest.java
import java.util.*;
public class FacilitysTest {
public static void main (String [] args) {
Facilitys entries = new Facilitys();
entries.add("Stage","3.56");
entries.add("kitchen","5.00");
entries.add("heating","2");
// System.out.println(entries.firstElement() );
System.out.println("printing out entries");
System.out.println(entries);
System.out.println();
System.out.println("There are "+entries.size()+" entries");
System.out.println();
System.out.println("modifying entry 2");
entries.setElementAt(new Facility("lighting","1.34"), 2);
System.out.println(entries);
System.out.println();
System.out.println("deleting entry 1");
entries.remove(1);
System.out.println(entries);
}the following is what happens when i run this code.
the number (0,1,2) is taken from a unique number assigned to the facility and is not anything to do with the facilitys position in the vector.
printing out entries
Facility number: 0, Name: Stage , Cost/Hour: 3.56
Facility number: 1, Name: kitchen , Cost/Hour: 5.0
Facility number: 2, Name: heating , Cost/Hour: 2.0
There are 0 entries
modifying entry 2
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2 >= 0
at java.util.Vector.setElementAt(Vector.java:489)
at FacilitysTest.main(FacilitysTest.java:17)
Press any key to continue . . .
Facilitys.java
import java.util.*;
public class Facilitys extends Vector {
private Vector entries;
public Facilitys( ) {
entries = new Vector();
public void add( String name, String price ) {
entries.add((new Facility( name, price) ));
public Facility get(int index) {
return ((Facility)entries.get(index));
public float total() {
float total = 0;
for (int i = 0; i<entries.size();i++) {
total = total + ( (Facility)entries.get(i) ).getPricePerHour();
return total;
public String toString( ) {
StringBuffer temp = new StringBuffer();
for (int i = 0; i < entries.size(); ++i) {
temp.append( entries.get(i).toString() + "\n" );
return temp.toString();
}are you reffering to where i have public class
Facilitys extends Vector {
private Vector entries;
public Facilitys( ) {
entries = new Vector();
That's correct. That's your problem.
i added the extends Vector, because without it i got
the following errors

hi all,
I am reading a binary file, then creating the object and adding that object in my vector. How can i get it back according to its id? let is say i added all the customers read from file and now i want to get customer 3?
int thisId=dis.readInt();
String thisName=dis.readUTF();
double thisBalance=dis.readDouble();
Customer cus=new Customer(thisName,thisId,thisBalance);
cusList.add(cus);
abdulBest possible way is to use Hashtable and put customerid as key and Customer object
as value.
Modify your code with,
Customer cus=new Customer(thisName,thisId,thisBalance);
some-hashtable-object.put(thisId,cus);
now if you want to take particular Customer
use
Customer c = (Customer)some-hashtable-object.get(any customerid);
Now if you don't want to use Hashtable and continue with Vector then you have to iterate the,
Vector and whether object has id 3 .
like
for(int i=0;i<Vectorobject.size();i++){
Customer c = (Customer) Vectorobject.get(i);
id = c.getCustomerId() // or any method you have to get id;
// check it....
But i think Hashtable is the better way to use here.
I think you understand what i want to say .

How to combine Session Facade and Transfer object?
Hello All!
I'm working on an enterprise application. Presentation layer is a stand alone client, business logic is build on the Glassfish v2.1 and MySQL is used as a database. The client is connection to the GlassFishj server remotely using EJBs.
I have problems with business logic architecture.
Here is the brief description of backend application architecture design:
1. Session Facade pattern is used to simplify the client and application server interface and to provide application layers between backend (http://java.sun.com/blueprints/corej2eepatterns/Patterns/SessionFacade.html).
2.Transfer Object pattern to define update transfer objects strategy in order to decrease network overhead during client and application server interactions and to provide version control for objects. Transfer objects are designed as simple java business serializable objects. (http://java.sun.com/blueprints/corej2eepatterns/Patterns/TransferObject.html)
3. Originally the backend application consisted of three modules: users, storage and orders, but at the end I have decided to divide my application into the following parts - assortments, map, menu, orders, transactions, users.
4. All MySQL database transactions are via JDBC using procedures. No use of entity beans.
Questions:
1. I have some doubts about using Session Facade and Transfer object patterns at the same time. At first I'd mike to cite the definitions of the patters from the SUN official web site.
* Use a session bean as a facade to encapsulate the complexity of interactions between the business objects participating in a workflow. The Session Facade manages the business objects, and provides a uniform coarse-grained service access layer to clients.
* Use a Transfer Object to encapsulate the business data. A single method call is used to send and retrieve the Transfer Object. When the client requests the enterprise bean for the business data, the enterprise bean can construct the Transfer Object, populate it with its attribute values, and pass it by value to the client.
* So, if I use Transfer Object along with Session Facade, it makes some difficulties with object version control, because I 2 or
3 transfer objects controls with the 1 bean class. The best option for Transfer object Pattern is that each transfer object should have its own bean class to provide ability of object's version control. In the case it can bring the network overhead because of frequent remote calls caused by the large number of the bean classes.
* So, should I use the both patterns? If yes, how to manage the interaction the patterns. If no, which one to use.
2. E.g. I have a huge list of the Order objects and each Order object consists of other complicated objects. So, would I have trouble to transfer that list over network? If yes, how to manage it.
Thank you!

I would simply recommend establishing a service tier. Your services should be stateless. You can go the extra mile and have a session facade, but in the majority of cases, coding to an interface for your service accomplishes the same goals.
2.Transfer Object pattern to define update transfer objects strategy in order to decrease network overhead during client and application server interactions and to provide version control for objects. Transfer objects are designed as simple java business serializable objects. (http://java.sun.com/blueprints/corej2eepatterns/Patterns/TransferObject.html)
The idea of the transfer object is very similar to the Command pattern. I think if you investigate that pattern, it will be more obvious. The transfer object reduces network latency by consolidating all the parameters into an object, ideally, this also consolidates multiple method calls. If you combine a transfer object (or command object) with a service tier, you get the best of both worlds. The service can delegate calls to helper objects (or other services or components) using the data in the transfer / command object.
3. Originally the backend application consisted of three modules: users, storage and orders, but at the end I have decided to divide my application into the following parts - assortments, map, menu, orders, transactions, users.
The is your domain. It will vary from application to application. The principles above are more general (e.g., patterns and architectural tiers) and should apply to most domains. However, your actual use case may require something different.
4. All MySQL database transactions are via JDBC using procedures. No use of entity beans.
Consider using something like iBatis or Spring's JDBC templating to make your life easier with JDBC.

Versioning is a separate issue. Generally, the more coarsely grained your transfer / command object is, the more changes are likely to impact dependent objects.
Your command or transfer object does not have to be a vanilla JavaBean, where you are basically creating a bean that has data from other objects. You can simply use your command / transfer object to encapsulate already existing domain objects. I see no need to map to a JavaBean with what you have described.
Generally, a method signature should be understandable. This means that many times it is better to pass the method, say, two coarsely grained objects than a signature with a dozen primitives. There are no hard and fast rules here. If you find a method signature getting large, consider a transfer / command object. If you want one service to delegate calls to a number of other services, you can also create a transfer / command object to furnish the controlling service with the data it needs to invoke the dependent services.
2. E.g. I have a huge list of the Order objects and each Order object consists of other complicated objects. So, would I have trouble to transfer that list over network? If yes, how to manage it.
This is a large, open-ended question. If you are going to display it to a user on a screen, I do not see how you avoid a network transfer with the data. The general answer is to not pass the data itself but rather a token (such as a primary key, or a primary key and a start and stop range such as you see on a Google search result). You do want to limit the data over the network, but this comes at a cost. Usually, the database will receive additional load. Once that becomes unacceptable, you might start putting things into session. Then you worry about memory concerns, etc. There is no silver bullet to the problem. It depends on what issues you are trying to address and what trade-offs are acceptable in your environment.
Thank you!
AstghikBest of luck.

Problem: Illustrator CS6 - print PostScript (fuzziness and blurring edges of vector objects)
Hello,
Earlier to print to the printer Develop Ineo+ 451 used the program Illustrator CS3. In connection with the transition to Windows 7 (64bit), was bought by a new version of Illustrator CS6 64bit. Unfortunately, when printing from Illustrator CS6 (price lists, business cards, labels) on a PostScript printer were detected problems, which were not in previous versions of Illustrator CS3.
A comparison of the print quality of the two programs Adobe Illustrator CS3 and Adobe Illustrator CS6, made on a PostScript
The software used on the computers:
1st PC: Windows XP SP2 (32bit), Adobe Illustrator CS3 (32bit), the driver Generic 50C-2SeriesPS v3.0.16.0 (32bit).
2nd PC: Windows 7 SP1 (64bit), Adobe Illustrator CS6 (64bit), the driver Generic 50C-2SeriesPS v3.0.16.0 (64bit).
Printer: Develop Ineo+ 451 (PostScript).
Drivers are available for download on the site www.chansi.ru
link http://download6.konicaminolta.eu/develop/public/&&BDV&RU&sw&&&&&0&&&0&&0&&0
(to choose Product Ineo + 452, for download tested version of the printer driver).
Because after using the new version of the driver, the print quality was not satisfactory, then for the correctness of the comparison experiment, already used driver version 50C-2SeriesPS v3.0.16.0 has been selected.
When you print from the program Adobe Illustrator CS6, a printer PostScript, you can see fuzziness and blurring edges of vector objects, small text becomes fuzzy and difficult to read. If you print from a program Adobe Illustrator CS3 (using the same version of the driver), there are not such problems and the print quality is quite satisfactory.
The settings in the dialog box "Print" of Adobe Illustrator and the print settings in the dialog boxes of the PostScript printer driver of Develop Ineo+ 451, were chosen exactly the same for both versions of the programs Adobe Illustrator CS3 and Adobe Illustrator CS6 on both operating systems!!!

P.s. Sorry for my English, use http://translate.google.ru/ and the help of friendsWhat's the explanation for the following sequence?
1. Paste as Smart Object, at moment after pasting and before clicking the commit icon (no transform was made) in options bar. The object is rendered pixel-perfect.
2. After the commit. The object is poorly rendered with gray pixels which should be white.
3. Press Cmd+T for transform mode. The object is rendered pixel-perfect again.
4. After canceling transform mode, the object is poorly rendered again. -

Any way to simplify vector objects in a PDF file?
I have a page with complex maps. This PDF is placed in InDesign, scaled, and then I export to create a new PDF. Either at the source (linked PDF) or the final PDF, I'd like to simplify the vector map images, presumably by rasterizing to 72 ppi.
Any way to do this in Acrobat?
Thanks in advance,

GetAttribute of a Vector[] object
Hi,
I have created a Vector[] object and set it to
a session by session.setAttribute("somename", Vector[]).
However, i found that when i retrieve it, it gives me ClassCastException, pls help.
Here is my code:
Vector[] a ;
session.setAttribute("a", a);
Vector[] b;
b = (Vector[])(session.getAttribute("a"));
One more thing, i am sure the code is alright because at the same time, i have bound some String[] object to it and when i retrieve it , there is no problem.Hi,
I have located the real problem, sorry for wrong posting before. The problem should be like this:
public class test {
Vector[] a;
I add different no. of test objects to a[0], a[1], a[2].
session.setAttribute("a", a);
Then, i call
Vector[] b = (Vector[])session.getAttribute("a");
test tt = (test)b.elementAt(i);
This is fine and no problem when i first load the page.
However, if i made a small change to the jsp (HTML changes), and then when i reload the page in the browser:
The statement :
test tt = (test)b.elementAt(i);
gives me classcastexception.
I have checked the Vector[] b, it's not empty.
Do anyone know the logic behind ? -
Problem with Sessions and window.open
Hi,
Hi everyone,
Help Please!!!
I am working with Sevlet session objects and HTML forms and windows. I have an HTML form for the user to supply a username and password. Once the user clicks submit I need to open another browser window that has no toolbar, no location, no status bar, etc. The user should also be able to go back to that login screen and login again and open a 2nd, 3rd, etc. instance of the application. My problem is that each application is being asigned the same sessionId. I believe it is being asigned to the main login window and thus to the other child windows it opens. Is there a way to work around this? Do I need to make the user open another browser window to login? I need to be able to let the user open multiple instances of the application with unique session ids for each.
Any insight is GREATLY appreciated on this topic. Anything you can tell me about sessions (Java), IE, window.open would help greatly!
THANK YOU IN ADVANCE!!!
MATo achieve this, you must introduce another level of
abstraction to the Servlet specifications. When you
work with JSP/Servlets you use mostly the HttpSession
to handle user related tasks, and the aplication
context, for things that are common to all users. But
inside the HttpSession scope, you want to create
containers that have 'smaller' scope and are uniquely
identified.
A ipothetical scenario :Let's say that you must have
multiple connections to several databases, on each
database user rights beeing diferrent, and you must be
able to track user actions globaly, and eventualy
capture a 'Close Application event' and close all db.
connections.
1. when the user first accesses the login frame create
the HttpSession. In the HttpSession object, store a
Hastable (let's call it 'ConnectionTable'). Each
object in the Hashtable must identify uniqely a
database connection. Now, to create unique identifiers
ids, make the keys in the hashtable java.lang.Long
objects, created using System.getCurrentTimeMillis().
This guaranties there will be no possible confusion.
From each new open window, on each request to the
server, along with the usefull parameters, send the
connection identifier. When proccessing the request,
select the object from the Hastable wich corresponds
to the ID.
2. Now, the values in the ConnectionTable, must act as
the containers that I mentioned in the first
paragraph. The simplest way to do this is to have
again a Hashtable derived class to do the job, wich
exploses methods similar to HttpSession: setAttibute (
Object key, Object value) and getAttibute ( Object
key, Object value). This container may use internally
a Hashtable to store object, and explose only the
getAttribute and setAttribute methods for clarity. Any
way, this is a problem of implementation. Let's call
this class CustomSession.
Now, a textual activity diagram:
1 user accesses the main page, you start a new
HttpSession; In the HttpSession object, store the
ConnectionTable object.
2. the user enters the userID and pwd and adatabase
name, and a new window is opened. Let's supose the
data entered is valid.
3. when you process the login data, you create a new
CustomSession object. you put in it whatever you would
put in your HttpSession. You generate a unique
identifier using System.CurrentTimeMillis(). Put the
CustomSession object in the ConnectionTable, using the
generated id as key. Send the response.
..... later on .....
100. the user asks for a particular action to be
performed - e.g. a row deletion. The page contains a
form with text field where the user introduces the
row number, a submit button and a hidden input with
the ID.
101. you process the data. Get the ID from the request
object, get the ConnectionTable from the session, get
the CustomSession using the ID as key, do whatever
your logic was doing, but obtaining the objects from
the CustomSession instead of HttpSession
NicNic,
Very slick idea. I think that it could work and it seems that there would be not security issues because the id that you would store on the client side is the Unique Identifier and not the actual Session Id. Do you forsee any security issues for this implementation? -
Issues in persisting dynamic entity and view objects using MDS
Hi All,
I'm trying to create dynamic entity and view objects per user session and to persist these objects throughout the session, I'm trying to use MDS configurations(either file or Database) in adf-config.xml.
I'm facing following two errors while trying to run the app module:
1. MDS error (MetadataNotFoundException): MDS-00013: no metadata found for metadata object "/model/DynamicEntityGenModuleOperations.xml"
2. oracle.mds.exception.ReadOnlyStoreException: MDS-01273: The operation on the resource /sessiondef/dynamic/DynamicDeptEntityDef.xml failed because source metadata store mapped to the namespace / DEFAULT is read only.
I've gone through the following links which talks about the cause of the issue, but still can't figure out the issue in the code or the config file. Please help if, someone has faced a similar issue.

//////////////////////////////////////////////////////////////////////////////////////////////////////////Hi Frank,
I m trying to save entity and view object xml by calling writeXMLContents() and saveXMLContents() so that these objects can be retrieved using the xmls later on.
These methods internally use MDS configuration in adf-config.xml, which is creating the issue.
Please share your thoughts on resolving this or if, there is any other way of creating dynamic entity/view objects for db tables created at runtime.

Difference between vector obj.clear() and Vector obj = null
What is the difference between clearing the Vector object with .clear() method and assigning null value to Vector object?
As per memory point of view, is it advisable to first clear vector and then assaign it to null for garbage collection or it doesn't make any difference.
Vector may contains large volume of data.
Please reply this if any one has fair idea regarding this.
Thanks in advance.
DeepaleeWhat is the difference between clearing the Vector
object with .clear() method and assigning null value
to Vector object?
Vector victor = new Vector(); //victor is a reference to a Vector object
victor.clear(); //now that Vector object has no elements
victor = null; //now victor is a null reference; it doesn't point to any Vector object
//if that was the only reference to that Vector, the Vector is now available to be GC'ed.
As per memory point of view, is it advisable to first
clear vector and then assaign it to null for garbage
collection or it doesn't make any difference.Hard to say. My gut says there will be no advantages to first clearing it. You'd have to try and measure. -
How do I prevent the Darker Shade Box (color shift) around Vector Objects when Printing
Sorry in advance for the novelette. I am absolutely mystified and frustrated and would love some help! I've been working on this problem for about 30 hours over the last 4 days to figure out what the heck is happening and cannot find an answer through various forms of research.
Basically, when I print a JPEG, I am getting this area (a box) of darker shaded coloring around my heart and love text. I've tested it a million different ways and am at a loss as to what the problem is ... is it an application problem, a color profile problem between my applications and printer, an improper way that I saved my file, etc.
Here is a photo I took of the image printed out (so it is slightly skewed from camera distortion):
The details:
(1) I create graphic art and sell it online. I save all of my printable art as JPEG files because of my customer base (diy hobbyists that print on their home printers without much knowledge base nor graphic design software).
(2) I use both Adobe Illustrator (AI) and Photoshop Elements 11 (PSE11) to design and save my artwork.
(3) I insert JPEG images into Microsoft Word 2003 documents to "test print" since most of my customers use home printers to print. Since most people have this basic software, it is a good gauge of the kind of print out they might get using the same or similar software.
(4) My PSE11 color profile setting is the default sRGB. I have test printed many times and I get the truest colors with this color profile.
(5) My AI color settings are normally also an sRGB color mode, but on occasion, I use a CMYK color mode if I am creating a larger document that I know the customer will need to take to a professional printer to print out.
(6) I do my home printing (for proofs) on an Epson Stylus Photo 1400 (which has the 6 color ink cartridges).
(7) Until this printing problem occurred on this test print out, I always used the "photo enhance" option when I designate settings for my printer via the Microsoft Word documents.
IMPORTANT: This is when I have the color shift?? or color rendering issues?? and it is the only time. If I use the regular ICM/ICC color profile of sRGB, the printing issue doesn't occur. Instead, I have a solid color background instead of this one with the strips of lighter color on the top and bottom. However, I can't control how the customer prints, so I need to feel confident that whatever color profile setting they use, they will not run into this problem. I even test printed the documents over at FedEx and the darker box/color shift did not occur.
(8) The document in question only has 3 sets of objects: the heart, the solid colored rectangle colored background and the text. All 3 objects are vectors, they are at 100% opacity and there are no "special effects" applied.
(9) The image was entirely created in AI this time and exported as a maximum quality JPEG file, although you will see below that I tried many ways to create and save the file so that I didn't have the color band borders on top/bottom.
(10) I regularly use AI for part of my art, then I drag it to my PSE11 open document and it becomes a Vector Object (it cannot by copying/pasting into a PSE11 document). I also regularly export AI images as PNG files, then insert them into an open PSE11 document. This printing issue has not occurred until recently. Here is an example of a very complex AI image I created, then inserted into PSE11 just to add the background (the Teddy Bear and books are AI vector objects) that were exported as PNG files then inserted into PSE11 to integrate with the background image - I test printed with Photo Enhance and had no printing issues:
So, from the research I have done, it looks like it is a color rendering or color space issue with conflicting color profiles in the same document. I checked my color profile settings and both sRGB and CMYK were set to embed ICC color profiles.
I tried changing AI settings to Preserve Numbers (ignore linked profiles) for CMYK, but that didn't work.
I also checked and made sure that not only the document setup showed the sRGB color profile, but that all the objects within the document also were converted to sRGB as well for consistency. That didn't work.
I tried converting the document to CMYK along with the vector objects. That didn't work.
I tried saving the heart image as a PNG file alone, the "love" text as a PNG file alone, both the heart and text together as a PNG files alone. Once saved as PNG files, I inserted them into an open empty PSE11 document - as I normally do. I then added the background color I wanted. That didn't work - the print still showed the color changes.
I tried dragging each vector object separately and even as a group and got the same color change issue when printing.
I tried "expanding" and "outlining" the text before exporting as JPEG, before exporting as a PNG and before dragging as a vector object into PSE11. Expanding the text did not help the situation.
I tried exporting as Adobe PDF, then opening in PSE11, then resaving as JPEG. That didn't work.
I tried flattening transparency (even though there is no transparency in the AI file). That didn't work.
I tried rasterizing the image. That didn't work.
Thinking that the file might be corrupt, I started from scratch and redesigned the same heart and love text. Unfortunately, I had the same problem as before. At this point, my AI started becoming buggy and would not open new files. It happened repeatedly and I decided it was best to uninstall and reinstall AI (and maybe that would fix the problem).
I created just the heart in AI, then inserted it into an open PSE11 document (both after exporting as PNG and also by dragging as Vector Object from AI). It seemed to work. I could both drag the vector into PSE11 from AI and export from AI as a PNG, then insert into open PSE11 document with a background color - and it printed a solid background.
So, I thought that reinstalling and setting back to defaults worked. But, then I added the love text around the heart and tried exporting as JPEG files and the same problem continued to recur. Whether I dragged as a Vector object into PSE11 (the heart object and love text separately and also another time with the vector objects dragged as a group) or saved them as PNG files and inserted into PSE11 - I got the different shades of color on what should be a solid background. I even tried saving the PSE11 as a PSD file first, then resaving as JPEG and I tried saving as PNG and printing and this didn't help solve the problem.
I really think it is some color conflict issue but I can't figure it out. I am definitely not very knowledgeable about color profiles and how to sync all my devices, however, as I mentioned, this was not an issue until recently (and I think??? I recall changing the CMYK setting from Preserve Numbers to embed color profile a month or so ago - however, it should have been solved when AI went back to its defaults upon reinstall).
The reason I believe it is a color rendering/color space issue is because I could see the color output when I saved the JPEG with CMYK color profile versus sRGB color profile and the sRGB colors were much richer, not surprisingly. The top and bottom colors matched the sRGB printout and the middle darker box section matched the CMYK printout.
I am sure it is something fundamental or simple and I am completely overlooking it. I wish it were just a transparency issue, because people know how to fix or do workarounds for it. But, there are no vector objects with any transparency ...
If I missed some detail, I apologize. Any help would be a dream come true at this point! lol
Thank you!Okay, I got motivated to try again. From doing a bit more research on troubleshooting AI printing problems, the Adobe article talks about print drivers. It was advised to uninstall and reinstall the print driver if the printing issue persists. So, I did. Unfortunately, I still had the same result after reinstalling and trying a test print! Ugh.
So, as Jacob said upfront, I seem to have an overactive print driver that is trying too hard (and it is a non-postscript printer which I realize is part of the problem).
There are so many variables in my situation as to how I create art and save/export art. I sometimes work solely in AI, sometimes solely in PSE and sometimes I use both programs to create. Consequently, I will:
(1) export directly from AI as JPEG if I am not adding PSE11 artwork.
(2) export directly from AI as PNG if I plan on inserting that image into PSE11 to add to artwork I have created in PSE11.
(3) drag vector objects as a Smart Objects directly from AI to PSE11 to add to artwork I am creating in PSE11 if I know I will playing with the vector object and resizing in PSE11.
So, I did a test print using scenario 2, where I inserted the heart and love text PNG (AI created vector object) into an old PSE11 document. This old document already had a vector object from AI with a solid background and I knew it printed correctly. So, after inserting this new PNG from AI into this old document, it printed correctly using the photo enhance mode.
However, I haven't had a chance to actually create new art in the older AI files (that I know print properly), resave as something else and try another test print (either by exporting as JPEG and printing in Word or by exporting as PNG file and inserting into PSE11 document, then saving as JPEG and printing in Word).
After testing the different possibilities of ICM settings within my printer, I found that the JPEG images printed out with the truest colors and best quality if I simply selected "no color management" from the printer. Shocker, huh? lol
MY SOLUTION: So, what I think I will simply do is add an instruction sheet with the printables I sell, explaining that the color profile setting should never be handled by the printer so make sure to turn off color management by printer (and if they feel they must use the printer for color management, make sure the setting is sRGB since I embed that color profile in my JPEG's).
Edited to add: Since my issue was never about how I could print a successful image (I knew I could simply change the color profile settings), but rather about how to make sure that customers would get consistent and high quality print outputs of my digital images, this seems like the best approach.
I don't think I will every really know exactly why I am now getting color shifts in the "photo enhance" mode when I did not have this problem a couple months ago - applying the same methods of creating artwork. I was concerned that I was saving/exporting using incorrect or mismatched color settings or something of that nature. However, since I went through the process of making my color spaces the same for everything, and I still have issue, clearly that is not the culprit. The only thing I can do to solve the problem and it is a straightforward solution anyway -> is to educate the buyer on how to print successfully (don't use photo enhance! ha ha).
Thanks again to everyone who chimed in and offered advice! -
Ps CS6 Problem: Incorrect rendering of pasted Adobe Illustrator vector objects
Ps CS6 v13.0.1
OS X 10.6.8
Problem: Ps CS6 incorrectly renders vector objects pasted from Adobe Illustrator. CS5.1 does not exhibit the problem.
Below is screenshot of artwork in Illustrator and which is copied to clipboard, followed by screenshot of "Paste as Smart Object" in Ps CS5.1 then screenshot of same paste in CS6. "Paste as Pixels" gives identical good rendering in CS5.1 and poor rendering (gray pixels which should be pure white in this example) in CS6. This is repeatable with other artwork.
Several weeks ago there was a complaint in this forum that Photoshop CS6 poorly renders vector artwork that is pixel-aligned in Illustrator. The Adobe response was that Photoshop is correct. Strange that CS5.1 can render pasted vector artwork perfectly and only CS6 makes a mess.What's the explanation for the following sequence?
1. Paste as Smart Object, at moment after pasting and before clicking the commit icon (no transform was made) in options bar. The object is rendered pixel-perfect.
2. After the commit. The object is poorly rendered with gray pixels which should be white.
3. Press Cmd+T for transform mode. The object is rendered pixel-perfect again.
4. After canceling transform mode, the object is poorly rendered again. -
Reset JSF session and the managed beans with sesison scope
Hi,
this is a very general question and maybe stupid for most of you. I have my jsf/facelets web application and i use inside of this application some managed beans, which are session beans. I want to know how is it possible to reset this beans. I'm asking this question beacuse i have this kind of problem: i built my web application which has a login form and i use the browser to test it. When i browse to the login page and I login with my credentials i get my customized home page. Then i open another istance of the browser and i browse to the login page again but this time i login as a different user. The result home page is the same as i got before with my login credentials, so the session is always the same. Instead i want the session and all its objects to be resetted for the new user! Do youn know which is the solution?The fact is that i want to have two sessions in parallel, so using the same browser and opening two tabs, i want to browse to the login page and access as two totaly different users and using in parallel the application without the problem of one user's action affecting the other user beacuse of session sharing. So I want to force the application to create two different session for the two users logins, because as i told you before as it is now, they are sharing the same sesison. And i think that if i at the login time I iterate thorugh the session and delete all the objects i will be able to have only one session per time. Isn't it?

When I use the Touch-up Object tool to select a vector element in a PDF and right click to Edit Object the object opens in Illustrator. This is the program I have set in preferences to edit vector objects. The issue I have is when I edit and save the object it shows up in the PDF shifted from its original position (offset to the upper left). How can I get the object to update in the PDF without shifting position?
Yes and No. You have the most up-to-date version of Acrobat 8.1 and
Illustrator, so the bug should have been fixed. I cannot say why it is
not working for you. Of course, the latest version of Acrobat is 9.0,
but I don't think you need to upgrade for the fix. Maybe someone can
chime in. What happens if you create a new file in Illy and create a
pdf, does the problem still happen?
