Help: CGI from apache to tomcat using GD::Graph

["Pons, Patrick" <pa...@eds.com>]

> Hi,
> 
> I'm experiencing the following problem:
>   - On the same server, I've installed apache and tomcat 4.1.18.
>   - I've copied my already working cgi programs (written using perl with
> CGI, GDGraph, ...). Everything is OK except... with graphics.
>   - Whilst this program output is correct with Apache, nothing is returned
> with Tomcat.
> 
> If someone could help me... I'm running out of idea.
