The FAQ: Why the Java Virtual Machine crashes when I use fonts on UNIX platform ?

states that:
This bug doesn't appear with the latest version of the JDK 1.3.

I'm not sure when this was written and when the most recent version of 1.3 was at that time and was just wondering, thanks. I am using 1.3.6 and was just wondering if that version was effected or not.

I was having the trouble of not being able to display a generated image on solaris using the cewolf chart jsp tag library and was getting the first error. After adding the System.setProperty("awt.toolkit", "com.eteks.awt.PJAToolkit") line to my jsp and adding the jar file to my lib directory in WEB-INF, the error turned into the second one. Is the PJA working or do I need to change something else?

The JDK 1.3.6 doesn't exist. If you mean 1.3.1_06, I think you shouldn't have problem...

Changing only awt.toolkit property isn't enough with JDK 1.3, please read the FAQ "What options do I have to add to java command line to use PJA with my servlet server on UNIX platform ?" to see what other properties or options must be set to run your servlet.

I got the same problem with mylacc.Every time I wrote 'new Font ("", Font.PLAIN, 10);' in my java servlet ,I get an Exception like this:
java.lang.Error: Could not find class: com.eteks.java2d.PJAGraphicsEnvironment
at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment.java:61)

at java.lang.Thread.run(Thread.java:484)
Every thing works fine with graphic.I can set color,draw rectangle,polygon in my java servlet.But once it runs into font or text,It doesn't work.When I use method getFontName(),I got an exception :
java.awt.AWTError: No default font : at least one .pjaf font must be loaded.
In case of an error related to font, you should run first PJAFontCapture to gene
rate at least one .pjaf font file.
Thanks.

Yes, I did mean 1.3.1_06. But I am still getting errors even after setting everything up, here's what it is, same as lcq210:

java.lang.Error: Could not find class: com.eteks.java2d.PJAGraphicsEnvironment
at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvi
ronment.java:56)

at de.laures.cewolf.taglib.CewolfChartFactory.getChartInstance(CewolfCha
rtFactory.java:101)

But I dont' understand what he meant by "In case of an error related to font, you should run first PJAFontCapture to gene rate at least one .pjaf font file." Because the FAQ states that ".pjaf files are useless with JDK >= 1.2"
Has anyone else gotten PJA to work on UNIX or Solaris using JDK < 1.4 with CeWolf?

Here is the start up line which begins my WebLogic 7.0 server:

$JAVA_HOME/bin/java $VM_MODE $JAVA_OPTIONS -Xbootclasspath/p:pja.jar:rtgraphics.jar -Dawt.toolkit=com.eteks.awt.PJAToolkit -Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment -Djava2d.font.usePlatformFont=false -Djava.awt.fonts=../../jdk131_06/jre/lib/fonts -Duser.home=applications/reports/WEB-INF $JAVA_PROPERTIES $SERVER_CLASS

And pja.jar, pjatools.jar, and rtgraphics.jar are in my Web Applications WEB-INF/lib directory. And I am still getting the exact same error. I am using CeWolf from cewolf.sourceforge.net which uses JFreeChart such as a previous user in this forum who was having trouble under the title "Are X11 library files required to run PJA?" Please tell me if I am doing somehting wrong or if there's anything you can do, thank you!!!

Answer was alot easier then you would think. It was not -Xbootclasspath/a:pja.jar but actually -Xbootclasspath/a:applications/reports/WEB-INF/lib/pja.jar because I had the pja.jar in my Web Apps directory. Seems pretty simple but when you are just trying to follow directions and not think why they are there and just copy paste, things can always go wrong, lol. If I had looked at PJAToolkitDemo1.2.sh closer I could have figured this out, oh well.
