jasper applet exception in webshpere

2004-09-09 19:24

I created a applet using JRViewer class to display the *.jrprint temporary files generated by jsp

on server side. The application can work perfect in Tomcat5.0.25, however, after deployment to websphere 5.0.2 the following exception occurs when the JRViewer is being instantialized. I've tried to display some browser side jrprint files or make websphere use Sun JDK(since the default JDK websphere use is IBM JDK, but Tomcat using IBM JDK also works properly),and all the attempts fail.

If there is anyone who encountered the similar problem ever?
