How do I set the context root in the Doors API using .xml files?

Hello everyone,

I am trying to deploy a number of API extensions on the same Websphere webserver as Doors NG (As per this question, https://jazz.net/forum/questions/176825/how-to-deploy-doors-next-gen-api-extensions-onto-websphere)

We have worked through most of the issues but I need to set the context root to "/extensions" without doing it manually during installation. I will upload a copy of my web.xml and ibm-web-ext.xml any tips on how to do this would be great.

Regards,
Andrew
