As sson as I started my NetBeans IDE I got an exception pop up saying

"A java.lang.NoClassDefFoundError exception has occurred.
Please report this at http://www.netbeans.org/community/issues.html,
including a copy of your messages.log file as an attachment.
The messages.log file is located in your C:\Documents and Settings\pradeep\.netbeans\6.5\var\log folder."


When I open my existing projects it shows "initializing projects",but it never happens.

This is what i got when I started TomCat...
