Hello all,

Is there anyway to pass a return statement back to a jsp?

(Reason why I ask is because sometimes my calling jsp will call a bean or servlet that will need to do response.sendRedirect() and do not want the calling jsp to continue processing...instead I want the calling jsp to just immediately redirect to avoid response already committed exceptions)

For instance,



To get the same effect as this at runtime:



Edit: Just to clarify a little bit. The reason why I do not want to handle the if/then return statement in the calling jsp is because I do not want others to have to write the if/then return logic into their calling jsps should they want to implement my bean/servlet.

Thanks!

No.
You can only "return" down one level in the call stack.
I suppose you could throw an exception to have it drop down multiple levels, but using exceptions to control program flow is bad karma.

You could possibly pass the data via a request attribute.
ie


Does that help?

Or you could move such processing out of the JSPs altogether and make any forwarding and redirection decisions in a serlvet controller prior to even getting close to a JSP.
