## org.hyperic.hq.product.servlet.filter
Class HttpServletResponseExt

    java.lang.Object
      javax.servlet.ServletResponseWrapper
          javax.servlet.http.HttpServletResponseWrapper
              org.hyperic.hq.product.servlet.filter.HttpServletResponseExt

All Implemented Interfaces:
  javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

    public final class HttpServletResponseExt

extends javax.servlet.http.HttpServletResponseWrapper

This is a very stupid class that is only required because the ServletResponse interface is brain-dead. You can _set_ the status code using the ServletResponse interface, but you can't retreive the response from it. This class extends the HttpServletResponseWrapper (which implements HttpServletResponse and ServletResponse) and overloads the three methods that can set the status code. All three overloaded methods save the status code in a private field, so that we can return that value when it is required. This feature is required for the JMXFilter.
