Iwan,
No it can’t. Since you are using Tomcat though you can specify your context information in a file named “context.xml” and store it in your WebRoot/META-INF folder. Tomcat should honor it when deploying your app. I’m not sure if it only does it when deploying a WAR or not.
I would suggest just save yourself the time during deployment, and copy it yourself into your conf/Catalina/localhost dir, you only have to do it one time.
