[xwiki-users] Run external script to generate data for wiki page

Hello all, I'm wondering if anyone has done anything like this before so, I thought I'd ask it here. Essentially, what I want to do is have a page / form that my users fill out and then submit. Upon submit I need to invoke an external script (e.g..Perl, Python, VBScript, Batch etc...) that will do some quick data gathering then insert some data in a database. Once the script generates the data the page will then retrieve it and render some results based on it. Most of the mechanics I can figure out I think, but I wanted to get some tips on the best way to actually invoke the script from a page in Xwiki. Any ideas or suggestions are appreciated...
