I'm having a problem with Guvnor after I create a single category, package, and rule. After completion, I logout and attempt to reenter the GUI but get an error box instead of the login prompt. The error has no data associated with ti and there are no exceptions in the log nor on the jboss console. At first I thought this was due to the version I was using ( from jboss,org and not jboss.com). I've since downloaded the dotcom version of BRMS standalone and still having the same problem. Another factor is that I'm attempting to use PostgreSQL 8.04 instead of Derby. The version of Java is 1.6 and I tried upgrading Jackrabbit from 2.1.0 to 2.2.1 with no help. The environment is Ubuntu 10.04. Both the Workspace and Version in the repository.xml use the same DB with different schemaObjectPrefix. Here's an example:
<PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.PostgreSQLPersistenceManager">
<param name="url" value="jdbc:postgresql://localhost:5432/Guvnor"/>
<param name="user" value="postgres"/>
<param name="password" value="XXXXXX"/>
<param name="driver" value="org.postgresql.Driver"/>
<param name="schema" value="postgresql" />
<!--<param name="schemaCheckEnabled" value="false"/>-->
<!-- <param name="copyWhenReading" value="true"/> -->
<param name="schemaObjectPrefix" value="version_" />
</PersistenceManager>
