How to read Action attributes from JSP fragments included with <jsp:include />?

StackOverflow https://stackoverflow.com/questions/19425754

Question

Trying to call an Action's getter from an included JSP, I get null:

MyAction.java

private String message = "The message I want to read...";
public String getMessage() { 
    return message; 
}

main.jsp

<%@taglib prefix="s" uri="/struts-tags" %>
<html>
   <head></head>
   <body>
       <div> I'm a DIV in main.jsp </div>           
       <jsp:include page="fragment.jsp" />
   <body>
</html>

fragment.jsp

<%@taglib prefix="s" uri="/struts-tags" %>
<div>
    I'm a DIV from fragment.jsp
    <br/>
    Message from Action: <s:property value="message" />
</div>

How can I get the attribute value in JSP fragment ?

Was it helpful?

Solution

Use <s:include value="somePage.jsp"> instead of <jsp:include page="somePage.jsp"/>.

If you instead want to stick with <jsp:include /> , you need to set 

<constant name="struts.ognl.allowStaticMethodAccess" value="true"/>

in Struts.xml, and it will work like a charm.

Don't ask me why, this is not mentioned anywhere in the documentation, it was a lucky discovery I made some time ago.
