AbstractMethodError on websphere 5.0.2.3

[Subashini Ramakrishnan]

Hi all,
I have an EAR which runs successfully on WSAD 5.1. However when I deploy the same EAR on WAS 5.0.2.3, I get an AbstractMethodError exception as follows inside a session bean where I am calling getSessionContext().getRollbackOnly().
[4/19/04 20:45:57:194 GMT] 54c72c SystemErr R java.lang.AbstractMethodError
[4/19/04 20:45:57:195 GMT] 54c72c SystemErr R at com.ibm.ejs.container.EJSContainer.getCurrentTx(EJSContainer.java:1
633)
[4/19/04 20:45:57:195 GMT] 54c72c SystemErr R at com.ibm.ejs.container.CMStatelessBeanO.getRollbackOnly(CMStatelessB
eanO.java:98)
Any pointers as to why this occurs would be very helpful.
Thanks.

Try re-generating the deployed code. You can do this during the deploy process by selecting deploy EJB.
The deploy code generator in 5.1 probably changed.

[Subashini Ramakrishnan]

I did that. I deleted all the old deployed code and the class files and generated deploy code afresh. The problem still persists.

[Roland Barcia]

You re-generated the code using the EJBdeploy.bat of the 5.0.2.3 server?

[Subashini Ramakrishnan]

No. I am building the EAR on WSAD. I am re-generating deploy code by right clicking on the EJB project and going to Generate --> Deployment and RMIC Code.

Are you deploying to a WebSphere instance server somewhere or are you testing with 2 different test servers within WSAD?

[Subashini Ramakrishnan]

I am testing on a separate WAS instance on a unix box.

[Roland Barcia]

When you install the EAR, explicitly select deploy EJB button in the install wizard. This will generate the deploy code using the EJBDeploy.Bat of the server.

Hi Roland,
I did that while deploying the EAR and tried. It still gives the same AbstractMethodError exception :-(

Is it something to do with the JDBC driver ? We are using DB2 Legacy CLI-based Type 2 JDBC Driver(XA) and COM.ibm.db2.jdbc.DB2XADataSource as the implementation class.
Any pointers ?
