hi, i don't really understand what went wrong, but my jasper report module gives this error when i try to install:

if any of you have a step-by-step tutorial on how you got jasper+ireports to work together a lot of less technical people *i'm kind of in that group* would be really thankful.

I don't know if that can help you.
It's a document in french for development on debian 5.0.3 with openerp 5.0.7.
Perhaps not the good method for deploiement or development, and not complete.

i'm going to try this fix again on a new machine. it's kind of hard to follow a translated technical google document. i really appreciate the effort put into the reply and pdf. i'll write back when i'm successful with this.

salam,
I have the same problem , you've fixed the bug ?
