ERROR after upgrade to ireport 0.4.1

2005-05-08 18:23

To all,

 

I have a problem after I upgrade the iReport from version 0.4.0 w/ jasperreports 0.6.1 into 0.4.1 w/jasperreports 0.6.4 and hoping that someone could help me to solve this problem.

 

I already recompiled the XML file using the ireport 0.4.1 and execute it.

 

I am using Java w/ JBuilder9 and JBOSS Server

 

However, I found this ERROR when i run the report

 

The ERROR found on Java EXCEPTION:

java.lang.NullPointerException

 

 

ERROR [org.jboss.web.localhost.Engine] ApplicationDispatcher[] Servlet.service() for servlet TPDReportServlet threw exception

java.lang.IllegalStateException: getOutputStream() has already been called for this response

what's the version of the lib that is using jbuilder? is the same that is using ireport?

 

ireport uses libs located in his lib directory these are not the same (most cases, if you don't whish configure them that way) that jbuilder uses.

 

Check that both versions be the same.
