Basic JAR Question

Hello,
I hate to ask such a simple question, but I'd like to get confirmation from people who know.
It is possible to package non-EJBs into a deployed JAR containing EJBs, isn't it? I have heard that you cannot mix a non-EJB class into a JAR that contains EJBs, but my interpretation of the literature I've found about packaging EJBs seems to indicate otherwise.
Basically, it looks like you would want to (or need to in some cases) package any class that an EJB depends upon through inheritance or through another association (e.g. a custom user Exception class that and EJB might throw) into the same JAR file.
Please reply and set me straight on this. Thanks in advance.
Jeff

1. You can include any classes in your EJB jar file, and it is widely used. You can also include other files (e.g. properties) and access them through the class loader (as resources).
2. If you use some libraries, you may reference them with Class-Path: element in your manifest file. It is not necessary to unpack the library and include its classes in your jar file. (About "Class-Path" -- look page about manifest in the java tutorial (in the JAR files trail)).
3. Your JAR can contain no classes, just a deployment descriptor, if your classes are somewhere and you have referenced them with "Class-Path". ;)

What are the basic .jar files to be set in web dynpro project classpath

Hi,
I am having a problem while customizing the ESS. I used DTR, DC and imported configuration. After that, I created project from one of the DC(say ess/jp/addr). Later when I open an iView from any Web Dynpro component, I am getting lot of errors without even making any modifications.
I closed the project and reopened it and reload & rebuilt, but it doesn't solved my problem. In my classpath settings I couldn't find any jar files except the jre_lib. Could you please let me know what are the basic jar files we have to set in classpath and where to get them from. We are using NWDS 7.0.06 version.
Can you please let me know how to solve this or any other way to work around this.
It's an urgent to be fixed as early as possible, plz help me out.
Thanks & Regards,

Hi Julien,
Thanks for your reply.
We imported the the specified SCAs in our track.
we are getting the following errors.

Basic iPhoto questions:

I have some Basic iPhoto questions before I start using the program:
- does iPhoto apply any compression or change images in any way when they
are imported?
- after images are imported, can the original source folder of images be deleted off of the mac?
- can Quicktime files exported from iPhoto be viewed on a Windows computer?
- can iPhoto handle large resolution images that might be as large as 8-15mb each? does it display them quick? are there any known file size issues?
Thanks!!!!

kat.
Is there a way to use iPhoto on a network so other users can read and possibly write to an iPhoto library on a networked mac?
iPhoto is a consumer level photo organiser, not a server. It's possible to share photos but libraries are very difficult and fraught with the danger of database corruption. Some have reported success.
Is it possible to password protect or secure certain images in the library so they can not be seen by anyone?
No. The best I can suggest there is to create a second library and store it in a secure area like a protected dmg. But remember, you can only have one library open at a time.
After photos are deleted from iPhoto, are there any remaining traces or cached files anywhere other than the trash
If you delete photos from iPhoto and empty the iPhoto trash then the pics are removed from the Finder as well. They remain as findable as any other deleted file from that point, which is, very, if the searcher in knowledgeable.

Object class deployment - Basic form question

OK, I subclass calendar object from Oracle provided standard
object class. What do I need to deploy to use this form now
apart from calendar.pll and my fmx. What about the object class
from which I sub-class. Do I need to compile and deploy that
also? How will form resolve this on run time the parent object
class as I really did not copy, just sub class and we do not
deploy original class? Basic form question. Thanks.

You can set the "help" property on the field (which gives you the little "information" icon link beside the field).
You could also try adding another field of another class above or below:
<Display class='InlineAlert'/>
<Display class='ErrorMessage'/>
<Display class='HtmlPage'/>
..etc

Adding Date/Time Field + X Number of Days - Basic Calculation Question

I am assuming this is a basic calculation question. New to Adobe LiveCycle Forms.
I have a simple form containing a table. The table appears as such:
Text
Formatted as Date/Time Fields
Header 3
Monday
user wil choose the beginning date (Date/Time) this is DateTimeField1
Tuesday
this should calculate DateTimeField1 + 1
Wednesday
this should calculate DateTimeField1 + 2
Thursday
this should calculate DateTimeField1 + 3
Friday
this should calculate DateTimeField1 + 4
Saturday
this should calculate DateTimeField1 + 5
Sunday
this should calculate DateTimeField1 + 6
Calculations are performed after the date is chosen for Monday. My mind tells me the simple calculation of DateTimeField1 + 1 is not going to work (and in fact doesn't!) as it needs to change Monday to a number first. I saw on another thread the following:
Num2Date(Date2Num(Date(DateTimeField1), "DD.MM.YYYY")+7, "DD.MM.YYYY")
Thought this was going to get me close. No cigars though!
Any quick help is greatly appreciated. And since I am new to this, details about what needs to be changed would be great too!
Thanks

Here an addition for you date field.
This FormCalc script in the exit:Event will check it the selected date is on a monday.
If not it will go the days back until the last monday.
var Selection = Date2Num($.formattedValue, DateFmt(2))
var WeekDay = Num2Date(Selection, "E")
var NewDate
if (WeekDay eq 1) then
          NewDate = Selection - 6
elseif (WeekDay eq 3) then
          NewDate = Selection - 1
elseif (WeekDay eq 4) then
          NewDate = Selection - 2
elseif (WeekDay eq 5) then
          NewDate = Selection - 3
elseif (WeekDay eq 6) then
          NewDate = Selection - 4
elseif (WeekDay eq 7) then
          NewDate = Selection - 5
else
          NewDate = Selection
endif
$ = Num2Date(NewDate, "EEE DD.MM.YYYY")
Hope this helps, too.

Basic Exporting Question

My main question is a very basic exporting question, but here is a super-condensed explanation of my big-picture goal for context:
Large (~450 MB) aiff on CD --> trim w/ Quicktime --> small (~16 MB) MP3 in iTunes
I would like to take an audio file (aiff) that is approximately 450 MB and export it from Quicktime and in doing so, reduce the file size and convert it to MP3. When I simply try to export it, it doesn't ask me about what size I want, nor does it give the option of MP3 formatting.
I have figured out how to reach my goal, but it's a mess. After I make my trims in QT, I have to:
1. select "share" instead of "export".
2. It asks me what size I want and I select small.
3. The file is then exported as a Quicktime movie into Mail and the size is reduced from 450 MB to about 20 MB.
4. I then have to "right-click" on the attachment in the email that is created,
5. save the attachment,
6. discard the email,
7. import the file into iTunes, and
8. create an MP3 in iTunes to finally arrive at my goal.
This seems like a ridiculously convoluted process to change a large aiff to a small MP3 and put it in iTunes. Any suggestions?

Thanks. I guess the basic answer to my question is that it can't be done in one or two fell swoops. The problem is that it starts on a burned disc, and I need to make edits to it before it ends up in iTunes (to be eventually used in iWeb). I was hoping to avoid juggling back and forth between iTunes and QT. I either would have to send it back to QT to do the edits after -->iTunes-->mp3, or import the large file from the CD to QT, make the edits, save changes, import large file to iTunes, convert to mp3.

Yup, a Jar question

i have really really tried to answer this question.
i searched the forums. i read the api.
so please, haha, please help.
i know jar questions dont typically get a warm reception.
I have a folder containing a couple folders and one jar file.
Images/
Data/
MyApp.jar
i cannot access the images in the Images folder.
im getting this error:
Resource not found: /Images/ToolBar/pic.gif
Uncaught error fetching image:
java.lang.NullPointerException
at sun.awt.image.URLImageSource.getConnection(URLImageSou

rce.java:248)
at sun.awt.image.ImageFetcher.fetchloop(ImageFetcher.java
at sun.awt.image.ImageFetcher.run(ImageFetcher.java:136)
this is the code i use to load images:
String imgLocation = "Images/ToolBar/" + imageName + ".gif";
URL imageURL = MyClass.class.getResource(imgLocation);i also tried it with a "/" before "Images" in the code.
I tried adding the folder to the manifests classpath.
I also tried knocking on wood and counting sheep.

the way my computer is configured i never use "-cp . " when
running a java program.
it usually uses the present directory as the class path.
but i have looked into that (maybe im doing it wrong).
im running "java -jar MyApp.jar" from the command-line (in XP)
from the directory that holds the .jar and the Images/ folder.
i tried "java -cp . -jar..."
i also tried putting the class path in the manifest file but every\ytime
i did that i got "no class in main" error.
if C:\My\Program contains MyApp.jar and directory Images/
Class-Path: C:\My\Program\Images
didnt work
Class-Path: C:\My\Program ; C:\My\Program\Images
didnt work
i tried the / both directions
ive tried countless permutations of this.getclassloader / getclass blah blah also.
every thread gives the class loader as the answer but so far
nothing has worked.
its amazing how many times this question has been asked and
there usually isnt an answer.
im depressed, haha.

Basic jar file usage question

I have developed a java project in eclipse. To develop this, I have used many external jars that I added in Java Build Path.
I exported this project as jar file.
Now I want to use class files in this project in the jsp page.
The problem is where should I put my jar file of this project and also the external jar files that I used. I made a WEB-INF folder in my project folder but still it is creating errors.
Please suggest.

HI,
I put both my project jar file, and the external jar file on which it is dependent in WEB-INF/lib directory. It can find my project jar file but not the external jars(axis.jar) and gives the errors as:
java.lang.NoSuchMethodError: org.apache.axis.description.ParameterDesc.setItemQName(Ljavax/xml/namespace/QName;)V
Could you please tell what is the problem. Under which path it looks for the external jars?

Basic JDBC Question

Okay, I think this isn't supposed to be in this forum (Seeing as how there's a JDBC forum and all..), but this is so basic and I'm kicking myself over it I thought I'd put it in here. Anyways:
I just installed mysql-connector-java-2.0.14, or at least I think I did. I keep getting the "java.lang.ClassNotFoundException: com.mysql.jdbc.Driver" error. I read a lot of the forum hits I got for the error, but none of them helped me out...
My JDK (I'm using 1.3.1_06 for compatibility reasons) is installed to /usr/java/jdk
I'm compiling an applet on one machine, but hosting it off another. The applet must then be viewed by the compiling machine, the hosting machine, and any other machines (which I do not have access to).
My question is this: What the hell am I doing wrong. :) Am I not understanding applets right? Does the client viewing it have to have the mysql driver installed? Does the server need it? I would assume only the compiling computer would...
And if I only need it on the compiling machine, what am I doing wrong? My environmental variables are set as shown, I'm compiling with the shown command, and the code snippets are from my stuff. Parts in bold are what I feel is relevent (in the paths). God I feel like an idiot...
Thanks in advance, and sorry to waste your time...

Basic Ant Question

Any Ant experts out there? This is such a basic question and I'm surprised it's not attacked point-blank in the Ant docs. I must be missing something.
I'm trying to use ant to build a makefile that can be used on both Unix and Windows. Basically the only difference between the two environments will be the name of the company root directory (designated by the environment variable CAEROOT which is defined under both OS's).
How can I access that environment variable with ant??? The obvious attempt shown below doesn't work because I guess Ant thinks it's a property.
<code>
<project name="XMLDBBridge" default="compile" basedir=".">

<property name="src" value="src"/>
<property name="build" value="classes"/>
<property name="caeroot" value="${CAEROOT}/"/>
<target name="init">

<tstamp/>

<mkdir dir="${build}"/>
</target>
<target name="compile" depends="init">

<javac srcdir="${src}" destdir="${build}" classpath="${caeroot}/JLib/OracleJDBC/;
${caeroot}/JLib/OracleXDK/lib/xsu12.jar"/>
</target>
<target name="clean">

<delete dir="${build}"/>
</target>
</project>
</code>

In case anyone else ever has this same problem.
I finally figured out how to get environment variables working in ant. It's quite nice but doesn't really figure anywhere in the docs even though I feel its one of the key usages for ant.
<code>
<project name="XMLDBBridge" default="compile" basedir=".">

<property name="src" value="src"/>
<property name="build" value="classes"/>
<property environment="envvar"/>
<target name="init">

<tstamp/>

<mkdir dir="${build}"/>
</target>
<target name="compile" depends="init">

<javac srcdir="${src}" destdir="${build}" classpath="${envvar.CAEROOT}/JLib/OracleJDBC/;
${envvar.CAEROOT}/JLib/OracleXDK/lib/xsu12.jar"/>
</target>
<target name="clean">

<delete dir="${build}"/>
</target>
</project>

Few basic SRM questions .......

I recently completed the SRM training from SAP and I have few basic questions and need help. Full points will be rewarded.
These are my questions and it is based on SRM 5.0 Classic Scenario with R/3 backend
1. Invoice & confirmation transferred to R/3 via ALE ? . All other documents are transferred to R/3 via RFC?
2. Based on the configuration, if the material is available in the backend then reservation will be created. Other wise PO will be created. For text items, PR will be created.
     a. Who (purchaser) will process the PR in R/3 and how it is processed?.
     b. Who (purchaser?) will process the reservation in R/3 and how it is
         processed?. Assume no sourcing is setup in this case and No MRP run.
3. How the vendor is linked to the Material or product category in SRM?. During the vendor replication from R/3, vendor and material/prod category link is automatically maintained?
4. How the vendor is linked to a specific purchasing org/group? Is it based on the prod category assigned in the org structure for each purchasing org or purchasing group?
5. How to do delta prod category replication?
6. How to do Delta Material Replication?.
7. Contracts and vendor list:-
    In our SAP training we created these from the browser. But in the actual
    implementation how do we create this?. Is it always from the browser?
8. Direct Material and Plan driven Procurement.
   Can we use catalog items as direct material?. Just for example - > What
   about Car Batteries that is directly used in production and has the inventory
   also. But we are using electronic catalog for procuring this item. Is it possible to
   order this as direct material?
9. How to replicate Plant. How to use DNL_PLNT?. Is BBP_LOCATIONS_GET_ALL will replicate all the PLANT's and its locations from the R/3 backend?
10. In the HR system, which transaction we can view the org structure?

You can use the following three routines to download locations from the backend system and store them as business partners in SAP Enterprise Buyer.
BBP_LOCATIONS_GET_ALL
To get all the location numbers from each backend system that is connected
BBP_LOCATIONS_GET_FROM_SYSTEM
To get all the location numbers from one particular backend system
BBP_LOCATIONS_GET_SELECTED
To get selected locations
Previously, locations were not given business partner numbers in SAP Enterprise Buyer. If you are configuring an upgrade, you can use routines BBP_LOCATIONS_GET_FROM_SYSTEM and BBP_LOCATIONS_GET_SELECTED to check that the following conversions have been made:
·        Conversion of user favorites
·        Conversion of user attributes
·        Conversion of old documents
Routine BBP_LOCATIONS_GET_ALL checks these automatically.
Once you have run the routines, the location data is available in the SAP Enterprise Buyer system. Table BBP_LOCMAP contains the mapping information (in other words, which business partner number corresponds to which location in which backend system).
For more information, see SAP Note 563180 Locations for EBP 4.0 plant replication

Basic swing question

I just started looking at swing yesterday because I want to provide a GUI to replace a command line utility we use. I've basically finished it but have a quick question about form - I will get some literature later but would like to get a feel from the people here. If you have a JFrame with a few JPanels each which contain some other components, what is the best practice for variable declaration? Should I just declare the variables locally or should I make them instance variables? The reason I ask is that I have a button that submits a message but that message is dependant on check boxes, etc. from from the frame. If I declare them at the method level I then have to start passing them around whereas if I declare them as instance variables I can access them very easily BUT this may not be good form.
For example:
my class is SendMessageToo so in the main method I have a line like:
final SendMessageToo smt = new SendMessageToo();
now all the instance variables that I have can be accessed my the methods simply using smt.methodOne(), etc. Does that seem OK or is it just pure crap? :-)

Thanks, that was something that crossed my mind before I just made eveything an instance variable. It was during that process that I thought, do these all need to be instance variables? Then I thought, SHOULD they all be instance variables. At that point my brain imploded so I came here. :)

Basic Encryption Question

Hello all,
I am trying to do a basic string encryption and decription but am getting an exception.
java.security.NoSuchAlgorithmException: Algorithm DES not available Here is a code that I found online and I am trying to run it as an example. I am using j2sdk1.4.2_08 and have included sunjce_provider.jar in my class path.
package security1;
import java.security.Key;
import java.security.NoSuchAlgorithmException;
import java.security.Security;
import javax.crypto.KeyGenerator;
public class DESKeyGenerator {
    public static void main(String[] args) {
        Security.addProvider(new com.sun.crypto.provider.SunJCE());
        try {
            KeyGenerator kg = KeyGenerator.getInstance("DES");
            Key key = kg.generateKey();
            System.out.println("Key format: " + key.getFormat());
            System.out.println("Key algorithm: " + key.getAlgorithm());
        catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
}I am getting the exception at
KeyGenerator kg = KeyGenerator.getInstance("DES");I would appreciate any help.
Thankyou

Thank you so much wetmore.
I looked up online to find out about the bug and was finally able to solve the issue.
Here is what I have done, verbatim, as reported on the Eclipse's bug reporting website. The solution is from the thread mentioned in the link below.
" ------- Comment #13 From M.H. 2003-10-23 06:49 -------
@Gary Murphy: there is a workaround (somewhere posted in bugzilla) how to get
it running in Eclipse. In your run configuration, remove the default JRE lib
entry from the bootstrap classes and add external jars jce.jar, rt.jar and
jsse.jar instead."The entire discussion for other fellow developers can be found at:

Here are your remaining duke dollars wetmore.
Thank you once again.

Switching to mac, basic noob questions

Hi, I'm new to this. I have some xmas and bday money and i need a laptop. I have two desktop PC's (one XP and one Vista) and have had PC's all my life. I feel like switching it up and giving macs a try, it would make my purchase more fun. I've done some research and i think i want the black macbook with 2 gigs of ram. Here are some questions i need answered before going much further.
1.) I notice that every 6 months new macbook models come out. I also noticed that the last three (at least) have been very similar in hardware. Is it common that the new macbook probably coming out in the summer will be unvieled at macworld? If there is a big difference i might wait, i don't want to get the last model in a product line. Id the difference is another slight processor speed increase i won't bother waiting. As far as i know this isn't available information yet, so i'm just looking for a 'usually they do/don't' type of response.
2.) Is the apple care support really all it's cracked up to be? I'm not about to let my purchase go to waste on me, but at the same time if the support is rarely needed i might not bother. I'm a student and don't have too much money to blow if it's usually a waste. I generally like getting the warrenty for my things, i'm just looking for a more experienced opinion.
3.) Are the Apple stores in the Best Buys independent from Best Buy, or are they the same? I would like to put the 900 or so dollars i can down on this and put the rest of my best buy card to pay off over the next few months.
4.) If they're the same, does anyone know if the apple computers fall under best buy's "no interest for blank months of purchases over black?"
thanks!

Hi Thomes08!
Welcome to Apple Discussions.
It sounds like you're in the process of making an excellent decision to go with a 2.2GHz "BlackBook" and up your RAM to 2.0GB. I think you'll be extremely pleased with your purchase.
1.) Unfortunately, these forums are not designed to be used as a means of product speculation. Matter of fact, it's against the Terms of Use (of these discussion pages) to speculate on upcoming product releases. We'll have to wait the 2-weeks for Mac World to see what comes out, there's no way to have any insight into the excitement that Steve's Keynote brings to technology.
2.) I'm a big fan of AppleCare, mostly because it ensures peace of mind over the reliability of my product for the 3-years that it'll serve as my primary machine. While, I've had multiple Macs last beyond 3-years, I also typically swap it out for the "latest and greatest." Especially with a portable and your student discount. The cost of APP for a MacBook is a relatively "no brainer" especially if you consider the cost (for parts & labor) of even the most basic repairs if the machine falls out of warranty.
3. I'm not entirely familiar with the logistics of the agreement that Apple has with Best Buy, so I'd rather not speculate. I do know that Apple also offers financing options through BML (Bill Me Later) and Juniper Bank, but I'm unfamiliar with the specifics of a split payment. Buying an Apple product through Best Buy still entitles you to all the same "benefits" of ownership, so there's no advantage (or disadvantage) to shop @ Best Buy.

4 basic java questions..

ok so I already learned Java last year (in grade 11), but my teacher didn't really teach anything, we learnt everything by ourselves from the API... so theres a lot of things I actually don't understand, but for now I want to ask 4 basic questions:
1. What does static mean?
2. Why would u "final" a constant variable? ie. If you have a variable called SIZE which is set to 5, so if u want it to be a constant, just never change its value. But what does the keyword final do to it?
3. What's super? I see it sometimes, and my teacher showed us in the applet exampls to use super.paint(g) or somethign like that for the paint method, but I never use that because I noticed it works fine without it..
4. Whats a question mark? I saw a game that was made in java and it had a lot of places where it had a question mark , which was part of the syntax. For example,
int j1 = i != 0 ? i - 1 : 199;
OR
JUMPVEL = (fSuperSlime) ? 65 : 31;
I really don't understand these lines...
feel free to answer any of these questions...

wow cool...thanks.. that question mark thing is nice
saves a few lines..
now, about super, so u mean u can access the parent
class's variables?Variables, methods, constructors, if the access level is such that it's allowed.
