Luis Muñoz created OPENJPA-2560:
------------------------------------
Summary: Multiple persistence unit found on tomcat 6
Key: OPENJPA-2560
URL: https://issues.apache.org/jira/browse/OPENJPA-2560
Project: OpenJPA
Issue Type: Bug
Components: jpa, kernel
Affects Versions: 2.2.1, 2.2.0
Environment: Suse Enterprise 11 SP3
tomcat6-6.0.18
Reporter: Luis Muñoz
Persistence unit will be reported as duplicated on SuSE tomcat 6 installation
due to directory structure containing symbolic links. Reported as 'Major'
because it affects performance when creating entity factory.

There's only one physical jar file at
/srv/tomcat6/webapps/testpkg-domain-wsvc/WEB-INF/lib/testpkg-persistence-ext.jar
but openjpa search mechanism will think there are two different jars.
jar:file:/srv/tomcat6/webapps/testpkg-domain-wsvc/WEB-INF/lib/testpkg-persistence-ext.jar!/META-INF/persistence.xml
jar:file:/usr/share/tomcat6/webapps/testpkg-domain-wsvc/WEB-INF/lib/testpkg-persistence-ext.jar!/META-INF/persistence.xml
On the directory structure it can be seen /usr/share/tomcat6/webapps points to
/srv/tomcat6/webapps
ls -l /usr/share/tomcat6

There's a partial workaround to overcome most of the 'Found duplicate metadata
or mapping' messages. The appBase attribute of <Host> can be changed at
/etc/tomcat6/server.xml to point to an absolute path instead of a path relative
to CATALINA_BASE or CATALINA_HOME
<Host name="localhost" appBase="/srv/tomcat6/webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
The "multiple times" error will persist even if only one jar is mentioned after
the workaround was applied:
