Is it correct to say that a Java webservice cannot return a HashMap although it can return a List. If this is true can someone please let me know the reason.

You can do some voodoo with JAXB, called XmlAdapters, to be able to return a map. Check this link:
Best wishes!
It is sorta covered in the JavaRanch Style Guide.
