Hacking an WSRP portlet request using Groovy
I wanted to invoke a portlet without having to run it through a portal. I have a portlet currently deployed in Oracle Portal and figured it would be "fun" to try invoking it using Groovy--I didn't see any slam-dunk toolkits for this (I didn't look too hard). WSRP uses Soap, so the first step was firing up Wireshark to sniff a real request (sanitized to protect the innocent):
It would probably take a bit of trial and error to hack that for another portal/portlet, but who knows.
Putting this in groovy (stripping out the JSESSIONID):
Running this produces the following output:
If you have suggestions for a good library for this, or improvements to the groovy code, please comment.
