Configuring the Repository for Drools Guvnor

[Anonymous]

Hi,
I'm using Talend Platform for MDM 5.4.2 on Windows Server 2012 R2 and am attempting to configure the Drools Guvnor Repository in Talend Admin Centre, using instructions at
I used Drools -> Administration -> Repository Configuration to generate a repository.xml for connecting to an SQL Server database, placed this in tac\apache-tomcat\webapps\drools-guvnor\WEB-INF and edited the components.xml in the same location and edited tac\apache-tomcat\webapps\drools-guvnor\WEB-INF\workspaces\default\workspace.xml to use the same driver and JDBC URL.
When TAC is restarted tables are created in the SQL Server database and some data populated. However the Drools Guvnor web app is no longer available (HTTP 404) and the following error is logged in tac\apache-tomcat\logs\localhost.<date>.log:

Updated localhost.log extract as I'd copied the wrong error (default repository is in c:\Windows\System32 and has locking problems)

Note that the installation guide fails to mention that Drools 5.2 (as provided with with Talend 5.4.2) does not work with Java 1.7 and needs to have 1.6 configured in the startup script or service/daemon executable path. See https://jira.talendforge.org/i#browse/TUP-477
This doesn't fix the problem but at least means I can build Drools packages from the default repository.
