Installing orbeon and own war in weblogic

Hi,

We have been running ops and our own webapp in tomcat for quite a while. We use tomcat, and we do a Separate Deployment as explained in http://www.orbeon.com/ops/doc/reference-xforms-java.

Now, we have to deploy this two wars in weblogic, and I am not sure about the option crossContext
<Context path="/my-app" docBase="/path/to/my-app/war" crossContext="true"/>

It says that our war has to be allowed to forward requests to other web applications.
Any idea on how to do this in weblogic?

Thank you,
Best Regards
