Not able to add JSP portlet --- java.lang.reflect.InvocationTargetException

[Maruthi <ma...@yahoo.com>]

Hello,
 
I am able to find and add my JSP portlet in "Customize Pane" when i pressed save and apply button i am not able to see  it in the Home apge as sometimes other Portlets are displaying as usual except mine and sometimes i am getting following error "java.lang.reflect.InvocationTargetException".Can anybody tell  me how to rectify this problem?.

Thank you,
Maruthi.
