To expand on Don's answer. (I know he's busy. Thanks Don.)
Let's say you have the following Action (this is not a complete listing):
public class MyAction extends ActionSupport {
private String dataRetrievedFromSessionBean;
public String execute () throws Exception {
MySessionBean sb = getSessionBean ();
this.dataRetrievedFromSessionBean = sb.getMyData ();
return SUCCESS;
}
public String getDataRetrievedFromSessionBean () {
return this.dataRetrievedFromSessionBean;
}
private MySessionBean getSessionBean () {
// Some code to get your EJB.
}
}
In your JSP you can display this data with the <s:property> tag:
<s:property value="%{dataRetrievedFromSessionBean}" />
That's it.
You don't need to mess with Session scope, other interceptors, or any of
that stuff. It's very simple and elegant. Almost too much so. It eluded me
for a while, but now I'm really starting to get it, and it's good.
