Download Description

PK14175 resolves the following problem:

ERROR DESCRIPTION:
An application was developed using RAD 6.0 for WebSphere AppServer. It contained an application-scoped resource. The application was then installed in WebSphere AppServer 6.0 for
an application that only supports JCA 1.0. When the jndi name is searched for, a java.lang.NoClassDefFoundError results.

There is a single file at EAR level in META-INF directory, ibm-jcajndi.props.
The contents look like -

rar.object.jndiname:fvtadapter.rar:fvt.adapter.message.FVTMessag eProvider=aaaaaaa
rar.object.jndiname:fvtadapter.rar:javax.jms.MessageListener=bbbbbb
rar.object.jndiname:fvtadapter.rar:javax.sql.DataSource=ccccccc

rar.object.name:fvtadapter.rar:javax.jms.MessageListener=eeeeee
rar.object.name:fvtadapter.rar:javax.sql.DataSource=fffffffffffffff

The format of these ids israr.object.jndiname:rarURI:ID=jndiName

The JCA 1.5 code handles these definitions. The JCA 1.0 code does not.

LOCAL FIX:
None

PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Application Server users of version 6.0.2.

PROBLEM DESCRIPTION:
JNDI lookup added for the application results in java.lang.NoClassDefFoundErrror

RECOMMENDATION:
None

When embedded RAR functionality is used for defining the J2C Resource Adapters, this results in java.lang.NoClassDefError when the JNDI lookup is done. Embedded RAR processing results
in this error.

PROBLEM CONCLUSION:
Code was changed to accommodate the processing of an embedded RAR.

The fix for this APAR is currently targeted for inclusion in fixpack 6.0.2.7.
