In Response To: 

Hi all, 
 
 This is not a question specific to tomcat but more about servlets. 
 I am using a dispatcher forward to invoke another servlet. 
 Why do I get an exception --> java.lang.IllegalStateException: Cannot forward after response
has been committed
 
 For some reason I am unable to find good documentation to do complicated servlets invocations.
Does any one know?

slurpee to me.

Cheers,
