Spring in RAD7 with WebSphere 6.1 fails to find AbstractStatelessSessionBean

[tobias.thorn]

Hi!

Has anyone got Spring to work in such an environment?
I have problem to get RAD to find the AbstractStatelessSessionBean.
I have put the spring.jar in the classpath of the EAR project.
I get this result when i try to start the application:

I have allready tried the "undeploy redeploy" workaround for the similar problem in the forum. And I have allso tried to downgrade to spring 2.5.2 and rebuilt, republished and so on.. but to no avail.

Any ideas what might be the problem?

I would check how your spring jar is packaged in your application regarding to a class path loader order. Is your spring jar defined in a manifest of your ejb module? Or do you put your spring jar in the war module?

I am using Spring with WS 6.1 and I have not experienced with spring and a class loader at all. An example exploded ear file for me will look like this:

\META-INF\application.xml
myEJB.jar
spring.jar
comms-lang.jar
log4j-1.2.14.jar

In myEJB.jar, the manifest.mf will look like this
Manifest-Version: 1.0
Class-Path: spring.jar
commons-lang.jar
log4j-1.2.14.jar

The manifest.mf is very "sensitive" to changes in WS 6.x so I would modify it using WS jar dependency editor.

I got a very similar problem. Here is my situation:
- RAD7 with WAS6.1
- Three projects:
1) a EJB project with a session bean with spring (MyEJBwithSring)
Manifest-Version: 1.0
Class-Path: spring.jar
commons-logging-1.1.1.jar
2) auto-generated EAR project (MyEJBwithSringEAR)
3) a j2ee application client (MyEJBwithSringApplicationClient) containg a test class myServiceTest with main()
Manifest-Version: 1.0
Class-Path: MyEJBwithSring.jar
spring.jar
commons-logging-1.1.1.jar
Main-Class: myServiceTest
- EAR is packaged with the EJB and the Application Client
- WAS Sever v6.1 was started
- MyEJBwithSringApplicationClient was Run As was V6.1 Application Client

If Run without pull in spring.jar in the classpath of the luncher, got exception:
Caused by: java.lang.NoClassDefFoundError: org.springframework.context.support.AbstractApplic ationContext

If Run with spirng.jar in the classpath of the luncher, got a different exception:
This error indicates that the class: org.springframework.ejb.support.AbstractStatelessS essionBean could not be located while defining the class: xxxxxx
This is often caused by having the class at a higher point in the classloader hierarchy

Here is the complete console output for former:

Thanks in advance!

[YuLimin]

Thank you vksoft,
I met the same problem, but get solved by checking the manifest.mf .
Add spring.jar into classpath will solve the problem.

[reganjeremy]

Also if you right-click on your main EAR project and go to J2EE dependencies, do you have your spring.jar in there as well? For me that was a key part of getting it to find it in addition to having it in the manifest and in the sub-project's classpath file.
