Thanks Kai for your pointers. I am able to add  sourcePaths by extending
the class SourceMapper and using  PackageFragmentRoot.setSourceMapper(mySourceMapper)
. 

Now my probem is how to store the extra sourcePaths in .classpath file. I
tried hand-editing .classpath file  to have something like the following
: 
    <classpathentry kind="lib" path="D:/temp/myEclipseTest/foo.jar" sourcepath="D:/temp/myEclipseTest/src;D:/temp/myEclipseTest/mysrc"/>
where "sourcepath" has multiple src entries separated by ";". 

This approach doesnt work as  IPackageFragmentRoot.getSourceAttachmentPath()
returns null. It seems that someone is verifying  the sourcePath to have
a valid directory or filename. Is there any way to disable this verification
? Or any other way to achieve this by adding new attributes to <classpathentry/>
? 

Any help is greatly appreciated. 

thanks,
prasen
