It will work fine
but when i write the following code

<jsp:setProperty name="mybean" property="empId" value="<%=request.getParameter("empId")%>"/>

then it is not working

Answer 1

Use EL expression.

use ${param.empId} if you want to map request parameter.

<jsp:setProperty name="mybean" property="empId" value="${param.empId}“/>

PS: @Sheo you have to show exception stack trace.
