I am new to JSTL. Is there way to use a jsp local variable inside a <c:if> or <c:when>. I will give an example for my question:

test.jsp


I have tried this, and it does'nt work. Is there a way to do something like this?

Thanks for any suggestions

The JSTL and EL operate upon scoped variables, not scripting variables. In general it is considered poor practice to mix and match them. Either use scriplets or use JSTL, not both.

If you insist, you can create scoped variables from any scripting data with the PageContext.setAttribute() methods.

Nothing beats the JSP and JSTL specifications. Links can be found in the JSP FAQ.
