Codec problem?

[Oleg]

Hi,

When running the servlet that generates charts using JFreeChart 0.9.4 constantly getting exception that kills Java VM.

Does anybody have similar problem? At this point I have no idea whether it is VM related or the problem is in JFreeChart.

I'm running the servlet in Tomcat on Win2K workstation. Here is an error log that is generated by the VM when it dies...

An unexpected exception has been detected in native code outside the VM.

Looks like the exception is happening outside of the VM in ntdll.dll which the underlying Sun class is using for the JPEG encoding. I would suggest installing the latest service pack on your operating system. I haven't had any problems with either NT 4.0 SP6 or Windows 2000 SP2 with JBuilder 7.0 and JFreeChart.

If that is not an option, or doesn't work, have you considered PNG encoding instead of JPEG. It is loss-less, produces compact files, is supported by all modern browsers and will not encounter the same problems as the JPEG codec. I tend to always use PNG rather than JPEG.

Richard...
