1. Re: java.lang.IllegalStateException: Can't overwrite cause
peterj Oct 30, 2008 10:30 AM (in response to ouhk_etpu)The text you posted is part of a report the deployer prints after it finished deploying everything. This report typically contains no information about the root cause of the deployment failure. Earlier in the console log there should be a stack trace that provides the cause - find the very first exception stack trace and post it in its entirety.
Regarding the persistence unit, please post the source for your session bean, and the source for persistence.xml. Make sure you enclose the source code in 'code' tags. You can do this by selecting the text and then clicking the Code button. Click the Preview button and check the formatting of your post before posting it.
