adEjbModule error

[Mike Jones]

I'm trying to install one of the applications (MyBank) from a WebSphere tutorial in WAS AEs 4.0.2.
Lab: Build a WebSphere Application
url -> http://www7b.software.ibm.com/wsdd/library/presents/AE_SkillTrans.html
ftp://vadd1:bgm86zq2@207.25.253.53/1/wsdd/pdf/presents/WS40ST04L-1.pdf
I get the following error in the stdout log file:
X WSVR0040E: addEjbModule failed for com.ibm.ejs.models.base.config.applicationserver.impl.EJBModuleRefImpl (desiredExecutionState: START) (uri: Deployed_MyBankEJB.jar)
java.lang.LinkageError: Class WebSphereSamples/AccountAndTransfer/AccountKey violates loader constraints
The java AccountKey class from the tutorial follows. Can someone tell me why it violates the loader constraints?
Sorry about the formatting.

Also, a related question. Where do I lookup the information for a specific error code. In this case, does the output from the log "X WSVR0040E:" represent an error code?
Thanks,
Mike

Hi..
I am also experiencing a similar error.
Can somebody tell me how to get rid of this error

The problem is that you are running two EJB JAR files on the same server and you have a name violation. Remove one JAR file or rename the classes.
