Problems on Solaris

2005-02-03 05:00

Hi,

 

on my development machine (Win2000) the creation of JasperReports works perfectly. After moving to production environment (Sun Solaris) i get the following exception:

I did search the forums and tried this from within m servlet:

System.setProperty("java.awt.headless", "true");

 

But it didn't work.

 

 

Any suggestions?

Sounds like the headless problem, you need to start java using the -Djava.awt.headless=true option

Is there a difference between using the "-Djava.awt.headless=true" option and System.setProperty("java.awt.headless", "true");?

Okay, there is definitely a difference between those two ways. Setting the mentioned java option did it! :-)
