I'm not sure if your problem is like mine, but I had a problem with the awt toolkit. I have a server application. The server does not have X-Windows installed. This causes problems with awt, jasper needs awt..

 

However jdk1.4 allows you to pass a parameter to java -Djava.awt.headless=true, New awt code in 1.4 allows for servers without graphics. This solved my problem.
