Cannot build EJB jar file in NWDS

hello,
I changed java beans file, and tried to build jar file again, then the "build EJB archive" context menu is disabled so I can not make EJB jar file!
So frustrated.. NWDS recognizes the changes in the java files , right? How come there 's no Build menu..
Is there any pre-requisite to enable the menu?
I have no idea how I can build jar file..
Please give me a advice.. Thanks~!

You might check the weblogic.developer.interest.ejb.tools new group.
Make sure that the tool doesn't leave this ejbcgen directory around. It
should delete
that temp dir. When it doesn't it keeps all the old generated stuff around
and your changes won't be
reflected in the new jar.

Hi,
I have a problem with the EJBDeployerTool. When I want to update
a class file (for example, because I corrected any problem), the
deployer tool doesn't update the file correctly. It keeps the
old version of the class file.
In order to update a jar I have to copy the newer version in the
.ejbdeployer/provider-projects directory by hand. Is it a bug?
Is there any other way to do this? We are wasting too much time
in this task, instead of programming :_(
Thanks in advance,

Problem building EJB jar file using Eclipse

Hi,
Here's my file sturcture.
ejb\x\y\z\test\
ejb\x\y\z\test1\
'ejb' is the root directory.
The java source files under 'test' have a package name x.y.z.test.
The java source files under 'test1' have a package name x.y.z.test1.
I want to build a EJB jar file for 'test' and 'test1' separately. In eclipse when I create an EJB project, I specify the root folder as the source in the java build path settings. So the project explorer in Eclipse shows both the packages since they are under the same root folder. When I try to do 'Export - EJB Jar File', it includes both the 'test' and 'test1' in the .jar. Is there a way to build them separately ?
Thanks,

As far as I know, there is no way in Eclipse to specify a package prefix for a source folder. Assuming that you are not using an operating system with support for symbolic links at FS-level, the only way I can think of solving your problem is via linked folders and includes/excludes.
1. Create two ejb projects in your workspace. Specify locations somewhere independent of where the root of your source tree is located.
2. Right click on proj1 and select Properties / Java Build Path / Source.
3. Click Link Source and specify the location to your source root on disk. Click Next.
4. In the inclusion patterns section, add a pattern that captures classes appropriate for that module. Click Finish.
5. Delete the original source directory that was created during project creation before leaving Build Path configuration dialog.
6. Repeat steps 2-5 on the second project, except specify a different inclusion pattern.
This should produce a project structure that Eclipse will be happy with, but you have to be a little bit careful. Even though you filtered out classes from the view of the java compiler for a particular project, you will still see them listed in the various navigational views (such as Package Explorer or Project Explorer). Don't modify these filtered out files. The project that is supposed to be building them will not react to changes in the other project. You will have to manually refresh (right click on project and select refresh) the other project before the java compiler will see changes.
Hope this will help you out.

SQLJ: unable to find input file null   (Error while building EJB.jar file)

Hi,
I am working on open SQL/SQLJ with the following details

How to build a jar file so the program can access its resources folder?

I have a java program written by someone else in which I have made a trivial change (I changed the background color). The jar file runs but it does not find one of the resources file.
Here is the project folder's structure
mainClass.txt (manifest text file)
folder resources (includes file Java does not find: order.txt, a text file)
folder CFPT ( includes .class files)
folder cpl (includes .class files)
folder results
I tried
jar cvmf mainClass.txt CFPT0.jar CFPT/*.class cpl/*.class resources results
I get a lot of "adding: resources/..."
including the one pertaining to the files which is later not found
adding: resources/order.txt(in = 411) (out= 169)(deflated 58%)
the code that chokes right now is the following,
Object i = new Object();
InputStream is = i.getClass().getResourceAsStream("/resources/" + resourceName);
when I run java -jar CFPT0.jar the program runs
but it soon gives an error, cannot find resourceName order.txt (is == null)
I have Core Java Volume 1 page 498 but it does not help me figure out what I am doing wrong.
Can somone help me build the jar file correctly so the program can find its resources?
Is this a classpath issue? What do I need to do?

My last mainClass.txt file content:
Main-Class: CFPT.CFPTRunner
Class-Path: ./resources ./results
I also tried
Class-Path: resources results
Initially I only had the first line.
I put back /resources in the java file as the / is necessary to indicate absolute path.
Otherwise it looks relative to calling class.
I tried adding the path on the second line of the manifest file per Wikipedia example
http://en.wikipedia.org/wiki/Classpath
I looked at
http://java.sun.com/javase/6/docs/technotes/guides/lang/resources.html
If you use the -sourcepath option, the compiler searches the indicated path for source files; otherwise the compiler searches the user class path both for class files and source files.
http://java.sun.com/javase/6/docs/technotes/guides/lang/resources.html
resources
I took out the -d classes and compiled the .class files right with the java files in case that was the problem
javac -classpath . CFPT/CFPTRunner.java
jar cvmf mainClass.txt CFPT0.jar CFPT/*.class cpl/*.class resources results
java -jar CFPT0.jar
Still no go

ClassNotFoundException if ejb jar file is not placed in the server's classpath

Hi,
My ejb jar file contains some non-weblogic generated files and is placed in
the applications directory. When client is executed, I get the ClassNotFoundException
on the server when my bean makes a reference to the generated class. The problem
gets resolved if I put the ejb jar in the server's classpath.
This problem happens in weblogic server version 6.1. It was not happening in
the previous releases of weblogic server(6.0).

Well
I follow your instruction

There is option called EJB Archive this option builds your EJB. if your trying to create Web Module Project you can only create WAR file .

Hi John,
I am working on development an enterprise application using EJB 3.0 on Weblogic 10.
While developing, I am keeping all my classes (from ejb's as well as web) into APP-INF/classes directory. It is working fine for Web and ejb 2.0 packages, but ejb 3.0 packages, I get the following error when I keep my ejb 3.0 beans classes in APP-INF/classes directory.
No EJBs found in the ejb-jar file 'customer'. Please ensure the ejb-jar contains EJB declarations via an ejb-jar.xml deployment descriptor or at least one class annotated with the @Stateless, @Stateful or @MessageDriven EJB annotation.
One solution is to keep the classes under customer ejb directory, but I wan tto keep all the classes in APP-INF/classes directory so that when using Eclipse IDE I can output all compiled sources into APP-INF/classes directory.
Has anyone faced this situation? Any suggestions to fix this issue?

Deployment error when using several ejb-jar files

Hello All,
I am having problems with deployment of my J2EE application. My EAR file has several EJB-JARs, one for each entity bean. However I refer to the other EJBs in one EJB. Hence I included the <ejb-ref> element in the deployment descriptor of the entity bean. But I am getting the deployment error that "the bundle does not contain the bean name". I tried to change the <ejb-name> value (within the <ejb-ref> element) to the JNDI name of the EJB I am referring to, and also added the <ejb-link> tag specifying the location of the JAR file that has the EJB. None of the attempts worked.
Can someone help me out on how I am supposed to go about when I have several ejb-jar files as opposed to a single one? I am deploying my app on Sun ONE AS 7.0.
Thank you,
PS: I am posting this message on several forum topics. Please disregard this message if you have seen/answered this message. Thanks.

Hello,
Thanks for the response. I have got both Local and Remote EJB References, but for the JAR (where the ejbc compiler stopped) that I have an error, it is the local reference.

EJB relation mappings between different ejb jar files.

I have two local entity EJBs but they are in different ejb jar files. I'd like to make a relationship mapping (one-to-one, one-to-many or whatever) between them. Is it possible? To do that, I need <ejb-name> reference tag each other in both ejb-jar.xml, but how can I refer to ejb-name defined in different ejb jar files? Or as long as you make EJB relationship mappings, all EJBs must be in the same ejb jar file?
thanks,

Updating an EJB jar file on WL7.0

Hi
Iam attempting to update an EBJ jar file without taking down my WL7.0 server.
When I copy the jar file to the applications directory, I see the server accepting
the update but when I run my client the update is not visible! Iseem to be still
accessing the old ejb.
From my understanding, if the server is running in development mode I should be
able to copy the jar file with my update directly to the applications directory(
overwriting old jar file) and be able to access the udated ejb.

Hello Ron,
An alternative would be to modify a REDEPLOY file if your application is deployed
in exploded directory format. However, updating the EJB JAR should also do the
trick. Try going into the Admin console and explicity redeploying the EJB JAR
file after copying over the new JAR file. Let us know if any errors appear.

Hi ,
It would help if you could post the relevant snippets of your
ejb-jar.xml. In general, you definitely shouldn't use jndi-name
for any of the linking information. jndi-name is not part of the
standard deployment descriptor. The syntax for the ejb-link is
[ejb-jar uri]#ejb-name

How to deploy EJB jar file in Weblogic 8.1

Hi,
I have created the EJB jar file, bearing home,remote,ejb and client class aling with the META-INF folder containing ejb-jar.xml and weblogic-ejb-jar.xml.
After all this I am confused where to put this EJB jar file so that the container could deploy it.
I am putting it in application folder of my own created Domain.
Suggest me...

Put it anywhere you like. You can always deploy it using the administrator console. There usually is an auto-deployment directory for the domain. You could find all that information in the Weblogic documentation.

JAVA Proxy :: Exception in ejb-jar.xml in NWDS

Hi All
I am getting exception while Importing (Inbound) JAVA Proxy ZIP file in NWDS, ejb-jar.xml shows the red cross & when I double click on it got following error -->
The content of element type "ejb-jar" is incomplete, it must match "(description?,display-name?,small-icon?,large-icon?,enterprise-beans,relationships?,assembly-descriptor?,ejb-client-jar?)".
I already add the following JAR files in class-path -->
aii_proxy_xirt.jar
aii_msg_runtime.jar
aii_utilxi_misc.jar
guidgenerator.jar
One different thing I also notice is that after adding these JAR files in classpath I am not getting my Inbound Interface BEAN under EJB candidates.
Also nothing is visible under ejbModule usually it shows 4 JAVA files & one template file.
As a solution I tried searching in google & forum for above exception, most threads suggest to add the Beans to xml files but I am not getting my interface Bean under EJB candidates.
I also tried reloading all the external JAR files again from System but still same issue.
Also within the same NWDS one another version of EJB is working fine but I worked on it 6months back, I tried copy its contents to ejb-jar.xml source code but then also nothing happens.
I am using NWDS Version: 7.0.10
Can you pls. suggest & let me know what further information I can provide from my side which can help you to investigate it.
Regards
Lalit

hi,
Your are using server java proxy.
You can use some other jar files apart from what you are using,.
ejb20.jar
exception.jar
sapj2eeclient.jar
and after importing your zip file (create a ejb project first ,then add the zar files and then click on the ejbModule and then import your zip file ) close and open your project.
Do not directly click on ejb-jar.xml.Click on ejbModule and import the .zip file.
then save your .template file in ejbModule as a .java project.
then there should not be any error.
you can refer

How to configure maven to build EJB Jar?

Hi!
I would like to know how you setup Maven2 or alternatively Ant to build an EJB Jar.
I have managed to do this in Maven by adding required jars to my local repository and added dependencies in the pom.xml file. This, however, do not seem like a good solution. I would like set some kind of classpath for maven to look for all libraries included in my application server.
Could you please help me to solve this and I will be most grateful?!
