problem installing eclipse plug-in for portlet development

Hi All,
I am having trouble with installing the eclipse plug-in for the portlet development environment on eclipse. I get a cannot access URL error when I try the steps in the documentation and in the details section I get Unable to access http://xxxxxxxx:xxxxx/portletDeveloper3/.
Error parsing site stream. [The XML stream is not a valid default “site.xml” file. The root tag is not site.]
Error parsing site stream. [The XML stream is not a valid default “site.xml” file. The root tag is not site.]
I was also wondering if anyone had documentation/steps to follow on portlet developing on MWS 7.0. We have MWS 7.0 installed. And I am trying to connect from eclipse V3.0,JDK 1.4.2. Let me know if you need more details.
Any help on this is greatly appreciated.

hey there…i am facing the same problem…n e luck wid this one?

Probable cause is that the url for the plug in is wrong… can you access the url in explorer or firefox? If so, you should see a xml detailing the plugin files and stuff… compare the xml with any other eclipse update url > xml that you can access…
