how to use jstl variable in a jsp page

JSTL doesnt work with scripting variables (variables in scriptlets).

JSTL sets/gets variables in scope(page,request,session, application).

Thus

<%

int ack = Integer.parseInt(ackvalue);

pageContext.setAttribute("ackValue", new Integer(ack)); //set the Ineteger object in page scope

%>

<c:out value = "${ackValue}"/>

Seeing that you use the integer conversion for display purposes (ie in a c:out tag), it converts the Integer back to String. So you may as well have

<%pageContext.setAttribute("ackValue", ack);%>

<c:out value = "${ackValue}"/>

Does that help?

Hi,

Thanks for your immediate reply.

I am able to display the ackvalue when i am using

<c:set var="ackvalue" value="${ack}"/>

and <c:out value="${ackvalue}"/>

But my actual requirement is to use the ack value in switch statement. if i can assign the value to a String variable, then it si easy for me to proceed. Please help me in this regard.

Thanks,

You can use the c:choose, c:when and c:otherwise tags

<c:choose>

<c:when test = "${ackvalue == 1}">

//do stuff

</c:when>

<c:when test = "${ackvalue == 2}">

//do some other stuff

</c:when>

<c:otherwise>

//stuff

</c:otherwise>

</c:choose>
