Where does Eclipse store generated servlet files after jsp run on server?

I wonder many time that where the compiled jsp goes.I can't find it in the Eclipse workspace not in tomcat server directory.I read it in the book ,it say that  the compiled servlet save in the work directory,but I still can't find it.After some effort's fortunately, I find the storage location in the environment variables of Project. but it is tricky way.
 Now in good manner how to find the storage location of your tomcat server

•  Double Click on the server

• Now as arrow point to the location ,Catch this location in your Eclipse Workspace  

• This folder contain the Tomcat Server Container and other important stuff

• Conf is same as Same as Servers folder in your eclipse workspace 
• work folder contain the servlet file of jsp. "work\Catalina\localhost\YourProjectName\org\apache\jsp"
• jsp folder contain the java file and class file .Open Java file in the eclipse,this is compiled form of your jsp file
