Grapping raw request or PathInfo

[flipmind]

I have a portlet I can access using this URL

http://localhost:8080/portal/portal/torpedo7/product/ProductDetailWindow?action=2&productCode=TOBCWNNWB

I use the productCode parameter to show the product identified by the code.

I would like to use

http://localhost:8080/portal/portal/torpedo7/product/ProductDetailWindow/TOBCWNNWB

instead and extract the code from the URL. This is easy in a servlet. How can I get to the raw request from JBoss Portal 2.6?
