Hi, Kurt.
 
I have same problem as you on my Pluto portal ("...element
"env-entry"
occurs more than once.")
I have read your solution with help of
pluto.war/WEB-INF/data/xml/servletdefinitionmapping.xml.
But I need solution which allow me deploy portlet on Pluto portal and on
Sun Java Portal. Have you any other solutions of this problem or may be
advices.
Thanks
 
Best Regards,
Denis Tuchin
