Well, the <c:set> tag sets a request scope attribute. In java code you would retrieve this via request.getAttribute("action");
However request scope attributes only last for one request. Returning the JSP response marks the end of that. Submitting the form will create a new request So, no you won't be able to recover this value the way you have it now.
Suggestions - use a Session scoped variable - scope="session", and retrieve it with session.getAttribute() - If you want a value to be passed to the next page as part of a form, create a <input type="hidden"> on the form with the required value. You can then retrieve the string value via request.getParameter("nameOfField") as usual
Hi, thanks.. as is there any other way to do this, because my servlet is handling request from multipal jsp's as security i do not want to use form hidden filed. if i use session it overlaps with other action if i click on cancel. Thanks
