Is EL in jsp supported at all?
I've been trying to test 6.4.3 for jsp and am starting to think that OWB does not support web beans in EL in jsp pages at all. I have a jsp like this...
<%@page contentType="text/html" pageEncoding="UTF-8" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<link href="./css/default.css" rel="stylesheet"
type="text/css"/>
<title>Expression test</title>
</head>
<body>
<table>
<tr>
<td>${expressionBean}</td>
</tr>
<tr>
<td>${expressionBean.value == expressionBean.value}</td>
</tr>
</table>
</body>
</html>
with an ExpressionBean...
@Named
public class ExpressionBean {
private Counter counter;
@Inject
public void initialize(Counter counter) {
counter.create();
this.counter = counter;
}
public String getValue() {
return "foo";
}
@PreDestroy
public void destroy() {
counter.destroy();
}
public Counter getCounter() {
return counter;
}
public String getStatus() {
return counter.getStatus();
}
public String toString() {
return "ExpressionBean: status:" + getStatus();
}
}
and an app-scoped counter. The output from my jsp seem to indicate that EL is not finding or creating an ExpressionBean.
Am I doing something obviously stupid? Is there an example of EL + OWB + jsp working?
thanks

AFAICT, it works fine now for normal jsps. I haven't had a chance to dig in and see what is happening here.

Which jasper do you use btw? The tomcat-7 jasper I looked 6 months ago was pretty broken... Does it work now?

This property is set for this sample in geronimo, and the code in WebContainerLifecycle that adds an OwbELResolver is getting executed. I guess I'll have to look inside jasper to see what is going on.

There is a custom property to get the JSP chain ELResolver to register, I
believe to prevent us from being in the EL-Resolver chain twice in the JSF
case where we can't provide an instance of the bean, as eventually the JSF
chain delegates down to the JSP chain.
The property is:
#application is full jsp or not
org.apache.webbeans.application.jsp=true
Sincerely,
Joe

it 'used' to work back then. I think we also have an example for it.
