I am new to Drools. I have already integrated Drools with jsp. Now I want to know is there any GUI for Drools to run its application? Thanks
we are about to release version 6, which comes with the KIE-Workbench. Look at the web page and the docs to read about it. It will allow you to author and manage rules and business processes.
Drools Guvnor is the web GUI for managing rules:
http://docs.jboss.org/drools/release/5.5.0.Final/drools-guvnor-docs/html_single/
If you want a good overview of how Guvnor is used, it's worth checking out Michael Anstis's videos:

When it comes to running rules, that's obviously down to you to write your own application which integrates business rules.
As 'salaboy' mentions in his answer, coming soon as part of Drools 6, there is Drools Workbench. This is a major re-working of Guvnor. The following blog post lets you know what to expect:
