This is answered on the JasperReports forum.

 

Run your JVM on Linux with the parameter:

 

-Djava.awt.headless=true

Very thanks Sherman,

 

I put the parameter and solved my problem.

Hi,

My Tomcat server is on Solaris and I get the same exception but it appears sometimes and when I restart a tomcat, reports started working fine.

 

I havent set java.awt.headless=true;

 

My tomcat version is 5.5

and my jasper reports version is 3.0

 

Please let me know how can reproduce this problem everytime and how can I fix.

 

Regards,

Ankur

Hi,

I have the same problem as UniFloripa and I see with interest the swood's response.

I come to you to ask you how run my JVM on Linux with the parameter:

-Djava.awt.headless=true

As you can see, my level with java is fairly small :blush:

Thnaks in advance for your reply and help.
