Pattern help!

Hi, I would like to make a pattern out of this image in illustrator.
How can i do it?

This is not "pixel-perfect" but shows the concept:
In Photoshop, rotate and duplicate to create a repeating pattern:
Crop the pattern by finding any four corners that match, then import the pattern into AI and convert to Bitmap Pattern by dragging embedded bitmap image into Swatch Panel:
The original pattern can be converted to vector if required. I would recommend good, ol' fashioned pen drawing, not auto-tracing.

Hi,
I am not familiar with the document, but options I see are
option 1: set uncommitted data warning property on the af:document to "on" (I am not sure, but think this is already available in JDeveloper 11g R1)
option 2: use the controller context (ControllerContext) of the ADFc task flow handler to detect if the transaction is dirty
option 3: use a managed bean that accesses the AM in the DataControl to check if the transaction is dirty
FrankThank you for the reply Frank. Below are my response to your options
response to option1:
I have already set the uncommitted data warning property on the af:document to "on" (yes, the option is already available in JDeveloper 11g R1) and even set the bounded task-flow inside the region of my page as "critical", but when I navigate to other pages thru the navigation items in my template header, the prompt for uncommited changes did not show.
response to option2:
Which class of my project will use the controller context to detect if the transaction is dirty? I have tried to google the uncommittedDataWarning property which lead me to the DirtyPageHandler class. I have read on DirtyPageHandler class API that in case I do not set an implementation the default implementation will be used- and if I me quote from the API -"that default implementation will always return false from isDataDirty and will do nothing in response to a trackNavigation call." I wonder if aren't there any concrete samples to make this work? As I understand, the uncommitted data warnings is one of the publicized new features of JDeveloper 11gR1. Nevertheless, I have tried to follow allong and did create my own implementation:
1.) I did override the isdataDirty method to always return true,
2.) override the trackNavigation method to "System.out.println("prompt");",
3.) and created a file named oracle.adf.view.rich.context.DirtyPageHandler in the META-INF/system folder of my project, and
4) created a one line text which represents my implementing class in the created file in #3.
but still nothing especial happened.
response to option3:
What exactly is "AM" in the DataControl?
Your feedback on this is very much appreciated.
Thanks,

Regex Pattern help.

Me and my friend pedrofire, that�s probably around forums somewhere, are newbies. We are trying to get a log file line and process correctly but we are found some dificculties to create the right expression pattern.
My log have lines like:
User 'INEXIST' with session 'ax1zjd8yEeHh' added content '769' with uri 'http://mail.yahoo.com/'.
User 'INEXIST' with session 'ax1zjd8yEeHh' changed folder from 'E-mails' to 'Milhagem'.
User 'INEXIST' with session 'a8jXrY_N38ja' updated all content of folder 'Bancos'.
i need to get the following data
USER - [INEXIST]
SESSION - [ax1zjd8yEeHh]
ACTION - [added] or [changed] or [updated].
Getting the user and the session is easy, but i am having difficulties grabing the action, because i need to take just the action word without blank spaces igonring the words content or folder or all.
I m trying this for hours, but to a newbie is a little dificult
Any help is welcome
Thanks

Hi,
How about something like:
import java.util.regex.*;
public class RegexpTest
   private static final Pattern p = Pattern.compile(
         "^User '([^']+)' with session '([^']+)' ([^ ]+) .*$" );
   public static void main( String[] argv )
      find( "User 'INEXIST' with session 'ax1zjd8yEeHh' added content '769' with uri 'http://mail.yahoo.com/'." );
      find( "User 'INEXIST' with session 'ax1zjd8yEeHh' changed folder from 'E-mails' to 'Milhagem'." );
      find( "User 'INEXIST' with session 'a8jXrY_N38ja' updated all content of folder 'Bancos'." );
   public static void find( String text )
      System.out.println( "Text: " + text );
      Matcher m = p.matcher( text );
      if ( ! m.matches() ) return;
      String user = m.group(1);
      String session = m.group(2);
      String action = m.group(3);
      System.out.println( "User: " + user );
      System.out.println( "Session: " + session );
      System.out.println( "Action: " + action );
   }which results in:
Text: User 'INEXIST' with session 'ax1zjd8yEeHh' added content '769' with uri 'http://mail.yahoo.com/'.
User: INEXIST
Session: ax1zjd8yEeHh
Action: added
Text: User 'INEXIST' with session 'ax1zjd8yEeHh' changed folder from 'E-mails' to 'Milhagem'.
User: INEXIST
Session: ax1zjd8yEeHh
Action: changed
Text: User 'INEXIST' with session 'a8jXrY_N38ja' updated all content of folder 'Bancos'.
User: INEXIST
Session: a8jXrY_N38ja
Action: updatedYou should probably change the Pattern to be less explicit about what it matches. i.e. changes spaces to \\s+ or something similar.

Generic Proxy pattern - help needed.

Greetings!
Lately i have been working on some design architecture to work on possible ways of designing message flows in OSB.
I found one excellent solution called Generic Proxy pattern at: http://javamaster.wordpress.com/tag/osb/ .
This pattern consists of four proxy services.
Actually Generic Proxy pattern and proxy service are different. You can read more about pattern at : http://game-engineering.blogspot.com/2010/03/adapter-pattern-vs-proxy-pattern.html
My problem is interesting and very straight forward.
1. I have one proxy service which is created on client side WSDL.
2. I have one business service created on legacy system WSDL.
Now, if i want to implement this Generic Proxy pattern, I need to create two more proxy services in between my existing proxy service & existing business service.
On what basis should these two proxy services should be created?
Options in OSB to create a proxy service are : WSDL Web Service / Messaging Service / Any SOAP Service / Any XML Service / Business Service / Proxy Service
If anybody has worked in this pattern, please help.
Any inputs from everyone are welcome.
Thanks and Regards,
Swapnil Kharwadkar.

The generic proxy service will be of type "messaging service" with input/output type as text/XML.

Webservice, DAO/Bean Pattern - Help

All,
I'm stuck on this one - any help would be much apperciated.
I'm trying to expose a CFC which uses a DAO/Bean pattern and
am receiving the following error.
Could not perform web service invocation "getQuote".
Here is the fault returned when invoking the web service
operation:
AxisFault
faultCode: {
http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: coldfusion.xml.rpc.CFCInvocationException:
[coldfusion.runtime.UndefinedElementException : Element
QUOTEDAO is undefined in a Java object of type class
[Ljava.lang.String; referenced as ]
Here are my files to give you an idea of what I am working
with.
/webservices/application.cfm
/webservices/quote/quote.cfc (bean)
/webservices/quote/quoteDAO.cfc (my data access object, has
crud methods)
/webservices/quote/quoteService.cfc (service layer, i
generate my wsdl from this)
I have unit tested the CFC's by running a test.cfm file
within the /webservices directory which calls all methods. Works
fine. Additionally, the WSDL generates fine.
The problem is when I invoke the service, here is how I am
invoking it.
<cfinvoke
webservice="
http://localhost/apps/webservices/quote/quoteService.cfc?wsdl"
method="getQuote"
returnvariable="Quote">
<cfinvokeargument name="Quote_ID" value="200"/>
</cfinvoke>
It's important to note that within my application.cfm I am
setting up my quoteDAO and quoteGateway objects within my variables
scope. I am then setting my quoteService in my application scope,
like so:
<cfset variables.quoteDAO =
createObject("component","apps.webservices.quote.quoteDAO").init(variables.dsn)
/>
<cfset variables.quoteGateway =
createObject("component","apps.webservices.quote.quoteGateway").init(variables.dsn)
/>
<cfset application.quoteService =
createObject("component","apps.webservices.quote.quoteService").init(variables.quoteDAO,
variables.quoteGateway) />
I'm not sure what exactly the error I am receiving is, but
part of me cringes thinking it might have to do with pathing.
Any advice?

Simon,
Thanks for your reply - I modified the code to manually setup
those objects in my init like so.
<cfset variables.dsn = "mydsn" />
<cfset variables.quoteDAO =
createObject("component","apps.webservices.quote.quoteDAO").init(variables.dsn)
/>
<cfset variables.quoteGateway =
createObject("component","apps.webservices.quote.quoteGateway").init(variables.dsn)
/>
It solved that initial error but now I am getting:
Could not perform web service invocation "getQuote".
Here is the fault returned when invoking the web service
operation:
AxisFault
faultCode: {
http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: org.xml.sax.SAXParseException: Premature end of
file.
faultActor:
faultNode:
Any ideas?

EJB pattern Help!

Hi
guys!
I am newbie to EJB,A question puzzled me much these days.Help me plz :)
I know the EJB include three objects:EJBObject,EJBHome and XXXBean,The EJBHome object create EJBObjects by Facatory pattern.But,The EJBHome is an Interface,so does its subclass,How can an interface use create() method creating an EJBHome Object?
I don't know wthere I describe the question clearly .example as follws:
   public interface Converter extends EJBObject{
         public bussinessMethod1();
public interface ConverterHome extends EJBHome{
       Converter create() .....;
//Client
Converter currencyConverter=home.create();//<===
   //I can't understand it!home is an interface,and it isn't implemented(or only because i do not find out it )
the same question occered when I use the Serilizable interface,a class implement theSerilizable interface,then it is serilizable,too.but in the Serilizable interface,i can't find any clue How the serilizable works.
It maybe a stupid question,but ,Help me PLZ!
Thanx for your time!
kind regards
elant

First, a typical EJB is made up of a HOME, REMOTE and a BEAN. You are correct, your HOME and REMOTE are interfaces. The BEAN is your implementation class.
Converter currencyConverter=home.create();//<===
//I can't understand it!home is an interface,and it
isn't implemented(or only because i do not find out itWhat happens here is your application server will generate a subclass of your HOME interface and implete the create method. That method will, among other things, call the ejbCreate() on your BEAN.
the same question occered when I use the Serilizable
interface,a class implement theSerilizable
interface,then it is serilizable,too.but in the
Serilizable interface,i can't find any clue How the
serilizable works.To begin understanding the Serializable interface, take a look at the javadoc found at http://java.sun.com/j2se/1.4.2/docs/api/java/io/Serializable.html You may also wish to look for the tutorials found on the java.sun.com website.
Hope this helps.

Observer Pattern Help

hi,
I am trying to understand how and when you would use an observer pattern. I understand that it allows one class to observe another, i.e if a variable was to change in 1 class all observing classes would be notified of the change. I do not understand how u would implement this, I have seen some examples but they are kinda confusing does anybody have a simple way of showing how this pattern is implemented?
thx
sbains

Dish would be the observable in this case. Waiter and Chef are the /
contain observers. The observer's update method will get called whenever
the observable calls notifyObservers.
public class Dish extends Observable {
    public void setStock(int stock) {
        .. business logic ..
        this.setChanged();
        this.notifyObservers(new Integer(stock));
public class Waiter implements Observer {
    public void update(Observable o, Object arg) {
        Long stock = (Long) arg;
        .. business logic ..
}Note that Listeners are also implementations of the Observer pattern, if
that helps any.

Beginner Factory Pattern help needed please

hi people,
Can someone please explain to me in laymans terms what the use of the Factory pattern is. I went to http://www.research.umbc.edu/~tarr/dp/lectures/Factory.pdf
and it did nit help me too much.
I'd really appreciate it if someone could give me an abstract example of when the Factory pattern would be useful. The reason I ask is because I am researching into JDO and have come across PersistenceManagerFactory and think I would underdstand this better if I understand Factory's.
Many thanks.

Is the reason for the ConnectionHelper to allow us to use that as the return type in the getHelper() method, thus allowing us to have either the OracleConnectionHelper or DB2ConnectionHelper?
Yes. You want to achieve polymorphism. You are interested in the connect() method, not necessarily what database is used (not the best example in the world, normally you would care as different vendors have slightly different SQL syntax, but assume you were using no triggers, procedures or non-ANSI SQL).
So, are you basically saying that a Factory is a class that can be used to decide which of the two databases we are going to connect to?
Depends. In this instance, you name the database you want and the factory is responsible for returning the proper class. In other cases, you might have developed a program that works across databases and only uses one at a time. In this case, you would probably read in a setting at application startup, and the factory would always return the same object type.
If there is a PersistentManagerFactory, does it mean this would be used to decide what PersistentDataStore we are going to use (i.e. flat file, database, serialised object etc)?
Again, it depends. You can make your factories 'smart' by deciding where to serialize a given object (say, every domain model object has a method save() and your DAO uses the factory to get a connection to do its work). In other cases, you have a 'bare-bones' factory that simply returns the requested object type. Why go through all that effort? Well, one advantage is that I can put the factory, interface and any implementations in the same package. The only ones that (normally) would need to be public would be the interface and the factory. You can hide the implementation details using the security features of the language.
Also, why is OracleConnectionHelper a final class?[i]
In general, I make all variables, method signature parameters and classes final. Once I need to sub-class or re-assign a variable value, I remove the final clause. I can't count the number of times the compiler caught an error (rather than at runtime) because of the additional 'safety' declaring everything final gives you. Only make variables and classes (and method signature variables) non-final when you need to. IMHO, of course.

Design pattern help need urgently please

Hi I need you to tell me if the following code looks like its a facade or not?
The method make the table calls another method in the class project4
which contains instances of itself and student class and supervisor class and the method prints out data from these classes.
Iv to hand this in tomorow and would like to know
Is that a facade or not?
Please help
public class TableFacade
     TableFacade()
     System.out.println("This is the table of projects");
     public Project4 makeTheTable()
          Supervisor5 sup = new Supervisor5();
          Project4 project =new Project4();
          project.readRelevantProjectsFromFile(sup);
     return project;
}

Sorry to be continuously replying but desperate times call for desperate measures anyway
Im trying to adapt from my project4 class
is this in the adaptor pattern?
class AdaptProject
     Project4 project;
     Supervisor5 supervisor;
     void readProjectDetails()
          project.readProjectDetails();
     void readRelevantProjectsFromFile(Supervisor5 v)
          project.readRelevantProjectsFromFile(supervisor);
     String projName()
          return project.projName;
     String projSubject()
          return project.projSubject;

Route pattern help

I need a route pattern for
8XXXX, but needs to exclude the following ranges;
87000 ? 87199,
88470 ? 88519,
88520 ? 88569
I am a bit stuck, and don't want to enter loads it, can it be done with 1?
Thanks

All you need then is the 8XXXX route pattern pointing to CM B. If phone on CM A dials any extesnion registered with CM A (granted it has access to it's partition) it will be more explicit match. If there is no DN matching on CM 1 then the route pattern will be used, again assuming it's partition is listed in the phone's CSS.
HTH, please rate all posts!

Java Matching and Patterns - help please.

Ok, so I'm trying to take a CSV file and store it as an XML file using Java. Here's a sample line of the data file I'm working with:
1001,"Fitzsimmons, Des Marteau, Beale and Nunn",109,"COD","Standard",,109,8/14/1998 8:50:02
I'm trying to use regular expressions to match each field separately. I can't use split on "," because of the commas in the quotes (which is one whole field). So far, the first field matches to "[0-9]+," What would be the regex for the second field? "\".+\"," doesn't work, and I'm running out of ideas.

I know this doesn't help the immediate problem, but I just have to say that this is the reason why comma is not a good separator. Why doesn't the world wake up and use tabs? I would assert that the chance of a value containing an embedded tab character is slim to none, whereas the chance that it contains any "printable" character is much greater - leading to this very headache.
So actually this might help afterall, if you can get the separator changed.

Design Pattern help needed for MDI application

Hi,
I am writing an mdi application which contains a JSplitPane. The left pane contains a JTree and the right contains a JDesktopPane which houses n number of JInternalFrames. The JInternal Frames need access to the JTree. Also both panes (objects w/in) need access to elements of the JFrame. I am currently implemeting access by making most of the JFrame objects static and creating getter/setter methods for access. Does anyone know any desing patterns I might use to solve this dilemma?
Thanks,
John

The observer design pattern causes the child objects to chage state when the parent changes state. The type of pattern I need would allow the child objects of the parent JFrame to be available globally without having to make them static. I am wrong in this? Would the observer pattern solve this issue.

Patterns help

I am running into an issue using patterns. I am seeing lines where there the pattern overlaps or buts up against itself. Here is what I am talking about -
Some of the patterns I used for this project were created by me or supplied by my client, and on those I would think operator error would be the casue. But it is happening with the adobe stock patterns as well. This is a screenshot of the stock adobe cheetah pattern and I am still having the problem. Any ideas here, my client is seeing it on his end as well, so I need to get it resolved.
BTW, I have tried expanding, and that seems to work on some of them, but not all.
Thanks in advance for any help

Normally this is a screen rendering issue. Turn off anti-aliasing in the preferences, then it should be gone. If it's still there without anti-aliasing, there's indeed sth. wrong with construction

Pattern help!
