Question

i have two maven projects, project A contents some serializable model objects and project B is the GWT project. Now i want to use some Objects from project A for RPC calls between the client and the server in project B.

so here is what i have done yet:

GWT project B xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.4.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.4.0/distro-source/core/src/gwt-module.dtd">
<module rename-to='Index'>
<inherits name='com.google.gwt.user.User' />
<inherits name='com.projectA.Models' />

<inherits name='com.google.gwt.user.theme.standard.Standard' />
<entry-point class='com.projectB.client.Index' />

<source path='client' />
<source path='shared' />

</module>

Java Object project A xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.4.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.4.0/distro-source/core/src/gwt-module.dtd">
<module>
<inherits name="com.google.gwt.user.User"/>
<source path="./" />
</module>

I still get “No source code is available for type com.projectA.Object; did you forget to inherit a required module?” message =(

(POM dependency is set!)

Answer 1

i figured out i need to add this to the maven gwt plugin configuration in the POM of project B:

<configuration>
   <compileSourcesArtifacts>
        <compileSourcesArtifact>com.projectA:Models</compileSourcesArtifact>
   </compileSourcesArtifacts>
</configuration>

this tells the Maven GWT plugin to copy the sources to the web directory… Additionally you need an GWT xml file in the project B package with the following:

<module>
   <inherits name='com.google.gwt.user.User' />
   <source path='' />
</module>

That tells the GWT compiler to include the source of that module..

DONE
