Class StrutsRequestWrapper

java.lang.Object

javax.servlet.ServletRequestWrapper

javax.servlet.http.HttpServletRequestWrapper

org.apache.struts2.dispatcher.StrutsRequestWrapper

All Implemented Interfaces:

javax.servlet.http.HttpServletRequest, javax.servlet.ServletRequest

Direct Known Subclasses:

MultiPartRequestWrapper

public class StrutsRequestWrapper
extends javax.servlet.http.HttpServletRequestWrapper

All Struts requests are wrapped with this class, which provides simple JSTL accessibility. This is because JSTL works with request attributes, so this class delegates to the value stack except for a few cases where required to prevent infinite loops. Namely, we don't let any attribute name with "#" in it delegate out to the value stack, as it could potentially cause an infinite loop. For example, an infinite loop would take place if you called: request.getAttribute("#attr.foo").
