How to set env entries for deployment

Question

I have a JavaEE application that communicates with other services via RESTful API. The hostname:port of remote services is set through environment entries (<env-entry/> in web.xml, not to confuse with environment variables!). This value is later obtained through field annotated with @Resource.

As the build process is isolated from deployment, I want to override the defaults in web.xml (where the variable is set to localhost) that ends up in app.war to actual hostname. I suppose this is done by providing another web.xml or jboss-web.xml (on WildFly) along with , but I can't find how this is set up; I guess this must be a simple process, not involving repackaging the app.war.

Answer 1

You can use descriptor replacement property.
