I was using alfresco bundle with jboss. I've just download alfresco source code, and build a new alfresco.war, the following new tables where created: alf_*, jbpm_*. Where can i find information about these new tables??…actually only jbpm_* are new tables, the alf_* are a copy of the old tables.
If you get the latest code from SVN, and start Alfresco against an empty schema, then you'll notice it report running a SQL script. That script will contain all statements required to build the schema.
