Subject Re: Tomcat + Linux Server + Jasper Reports problem
Date Wed, 08 Feb 2006 14:55:50 GMT
Thanks everyone,
I've just managed to get rid of the error.
I set the display variable ":0" and then did a "xhost +". I also had to get
rid of the headless parameter, as you said I didn't need it.
Now my report successfully appears on my server.
The thing is that I wanted it to be shown on the machine that requested it.
If I'm in a client machine and request the report, I want it to appear on
this client machine. But the way it is, it always appears on the server.
But I think this is not a problem to be solved on this list, is it?

thanks very much everyone
