I just took a look at your configuration files. Actually I can't tell much from just them especially since I don't have the parent POM. Anyway I'm a bit confused about what you are trying to do.
Are you only trying to compile the sample project or are you trying to reuse something of it? What exactly do you mean with "project war rpc and server" or "war server"? A project that packages to a .war file (like GWT applications) or a .war file you are trying to include via module inheritance? I'm sorry but it's really not clear to me. 2010/12/22 Metronome / Basic <[email protected]> > Hello > Thanks for trying to help me ! > > One of my tries is : compile the "maven-googlewebtoolkit2-sample" > using gwt-maven-plugin > it was a three modules project war rpc and server > I reduced it to war server , by merging rpc and server > > I join the pom and web.xml of the war > > > mvn package report > > ERROR] Failed to execute goal > org.codehaus.mojo:gwt-maven-plugin:2.1.0-1:mergewebxml (default) on project > > maven-googlewebtoolkit2-sample-war: Unable to merge web.xml: > NullPointerException -> [Help 1] > > > > > > > > ----- Original Message ----- > *From:* Andreas Horst <[email protected]> > *To:* [email protected] > *Sent:* Wednesday, December 22, 2010 12:26 AM > *Subject:* Re: Modular rpc blues > > Another question just coming to my mind: > > Where in the inherited module are you declaring the RPC servlet? > > If you declare it in the inherited module's web.xml then make sure the > Maven GWT plugin parameter "webXml" properly points to it (Not sure how one > would do this - never did it myself - especially since inherited modules > usually come as a .jar.
