Webapp demo, get problem with JRun

2003-02-28 00:51

When I test Webapp demo (from jasperreports-0.4.5-project.zip) with JRun 3.1, i get error when lick "Execute" the JSP Example from PDF output. The following is error message:

 

JasperReports encountered this error :

java.lang.IllegalStateException

Also, when execute JSP Example from Html output, i can get the result but with no images which from image.jsp. However, it runs well with servlet example.

I also test with jakarta-tomcat-3.3.1on the same PC, it runs well even though also throw :

But when I run it on Tomcat 4.1.18LE, it's very OK with no exception.

I dont know why, but pls help me to find out the problem, I need to apply into my project which will be deployed on JRun.

 

Thanx in advanced.
