Hi,
I'm testing the wadl support and trying to run restlet in a servlet
container (from the svn source, r3631). I tried two solutions:
- just declare the ServerServlet and create a restlet.xml (see the
attached file)
- create a custom component inheriting from WadlComponent and declare it
in the web.xml (as described in the ServerServlet javadoc) with the
following constructor:
public RestletComponent() {
super("clap://class/app.wadl");
}
(This is my first attempt with restlet, so i maybe forget something)
It seems that "wadlRep.getApplication()" returns null.
In the both cases, i get a NPE:
java.lang.NullPointerException
