How to pass a parameter to an Action?

Question

Java

You can pass a parameter to an Action like this:
<s:form action="index?pageLevel=99">
But you need to pass it dynamically, for example,
<s:form action="index?pageLevel=<%=level%>">
or

<c:set var="pageLevel" scope="page" value="<%=level%>" />
<s:form action="index?pageLevel=${pageLevel}">

But it doesn't work. How to do it?

Answer 1

If you need to transfer parameters dynamically without writing them in struts-config.xml, then this can be done differently, for example, put them in request.
get it like that

String contractNo = (String)request.getAttribute ("contractNo");
