Subject Exceptions found while running servlet...
Date Thu, 10 Aug 2006 05:44:38 GMT
Is it OK to send this type of feedback to the list? please let me know
if not, and what subject conventions should I use (is there a link
about this?). I am not a Harmony developer, just a new user, I can
only provide feedback from my tests.


I am running a small webapp, using Winstone servlet engine and IBM JDK
1.4.2 SP4 on WinXP SP2. Runs fine. I switched to Harmony JRE (aug-4),
and found these exceptions:

1.- I see this error while using servlet includes and also at the end
of some pages:

java.lang.ArrayIndexOutOfBoundsException: 0..0 at

2.- Trying to generate charts using JFreeCharts (server-side):

java.lang.NoClassDefFoundError: org/apache/harmony/awt/gl/ImageSurface
	at java.awt.image.BufferedImage.createImageSurface(BufferedImage.java:659)
	at java.awt.image.BufferedImage.<init>(BufferedImage.java:352)
	at org.jfree.chart.JFreeChart.createBufferedImage(JFreeChart.java:1211)
	at org.jfree.chart.JFreeChart.createBufferedImage(JFreeChart.java:1193)
	at org.jfree.chart.JFreeChart.createBufferedImage(JFreeChart.java:1178)...

The JDBC related code is running fine, performance also looks very good.

I will contact Winstone developer to see if he can help in some way to
identify the problem. He already helped me a few months ago to help
identify a bug in GNU Classpath server socket API.
