Re: Retrieving HTTP Servlet Info

Hi Woonsan

I have this working, so I thought I would report results.

Using your RequestContext idea turned out to be not too useful. The problem 
is that RequestContext is an internal Jetspeed class, not one that is in 
JetspeedApi.jar. That meant that I would need to package a lot of internal 
Jetspeed jars into my application. A big red sign saying CLASSLOADER 
PROBLEMS AHEAD was spotted, so I backed away from that approach.

So I turned to the hacker's friend - the Java reflection API. With a bit of 
experimentation I managed to get the ServletContext, HttpServletRequest and 
HttpServletResponse from their portlet counterparts. The new class is simply 
in a jar that I put into the /lib directory, and it only imports the 
reflection, servlet and portlet apis.

A welcome extra is that we can now easily read URL parameters from the 
HttpServletRequest - something I think should have been included in JSR286. 
We use full-page portlets extensively, and IPC does not allow passing 
parameters to a portlet on a separate page.

Thanks for your feedback. I could create a Wiki page on this if you agree.

Regards

Ron

Hi Ron,

You can retrieve HTTP headers through PortletRequest#getProperties() and 
#getProperty(name), but you cannot retrieve portal servlet request 
parameters with those APIs.
You may retrieve and carefully use portal servlet request, portal servlet 
response and portal servlet config directly through 
org.apache.jetspeed.request.RequestContext#getRequest(), #getResponse(), and 
#getConfig().
RequestContext object can be retrieved as follows:

RequestContext rc = (RequestContext) 
portletRequest.getAttribute(RequestContext.REQUEST_PORTALENV);

Regards,

Woonsan
