Eclipse UserFriend
When I launch my application through "tomcat" after exporting feature of my product and then click "help contents", following exception is generated:

------------------------------------------------------------ ---------------

1. I have included its extension details in plugin.xml file.
<extension
point="org.eclipse.help.toc">
<toc file="toc.xml" primary="true"></toc>
</extension>
2. Added following dependencies :
org.eclipse.help
org.eclipse.help.appserver
org.eclipse.help.base
org.eclipse.help.webapp
org.eclipse.help.ui


Please help me with the solution.
Thanks in advance
