[jboss-jira] [JBoss JIRA] (AS7-6871) Entity Not Mapped Exception

[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/AS7-6871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12766344#comment-12766344 ] 

Scott Marlow commented on AS7-6871:
-----------------------------------

I appreciate your wanting to report this as a bug but it really doesn't sound like one to me.  Best place to ask for help for questions like this is in the AS7 user forums.  

Try to enable TRACE logging for org.jboss.as.jpa and you should see more (helpful) information in the console during deployment. Doc link is here https://docs.jboss.org/author/display/AS72/JPA+Reference+Guide#JPAReferenceGuide-Troubleshooting

After looking at the TRACE output, you might try moving the MY-JAR-2.jar into ear/lib folder (and reference via <jar-file>MY-JAR-2.jar</jar-file>).  Having the TRACE output enabled when you make this change, will give you an idea of what is actually occurring without debugging.

I'll close this jira as there isn't a bug to fix.

> The value of jarToScan = C:/Jboss6.0.1Alpha/bin/content/MYEAR.ear/MY-JAR-1.jar
