ANT task to include source files for GWT

I am trying to use : http://code.google.com/p/jspf/ within a GWT framework. I know that GWT needs source of the included classes. I have placed the code for jspf in my {SRC_DIR} and my build.xml contains this entry:

 <path id="project.class.path">
    <pathelement location="${basedir}/src" />
        <fileset dir="${war_lib_dir}" includes="**/*.jar" />
    <pathelement location="${javac_precompile_classes_dir}" />
 </path>

But when I run the ant task, it fails with :

[echo] Starting GWTC
    [java] Compiling module com.x.y.z
    [java]    Validating newly compiled units
    [java]       [ERROR] Errors in 'file:/u/v/XyzClass.java'

GWT needs the sources because it compiles it to JavaScript. The errors are because you have used source code in the client side of your application that isn't organized in a module file (.gwt.xml file) or you didn't inherit the module file. This is what the error refers to: did you forget to inherit a required module. Just adding the sources will not help GWT to find the sources, there must be a module file too.

To be able to use those sources there must be a module file present or you must create on yourself and inherit it in your module file. Here is the documentation on modules: http://code.google.com/intl/nl-NL/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html#DevGuideModules Although the documentation is somewhat brief on how to create your own module file for this situation.
