PJA Toolkit forum

I am attempting to run PJAToolkitDemo1.2.sh using the pja_2.5 Beta code on an XServe with Java 1.4.1. The script is:

java -Xbootclasspath/p:../lib/pja.jar:../lib/rtgraphics.jar \
-Djava.awt.headless=true \
-Djava.awt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-Djava2d.font.usePlatformFont=false \
-Djava.awt.fonts=/System/Library/Frameworks/JavaVM.framework/Versions/1.4.1/Home/lib/fonts \
-Duser.home=.. \
-classpath ../lib/pjatools.jar \
ToolkitDemo

I have created the rtgraphics.jar as recommended, with the Windows classes (and inner classes).

The stack trace I get when executing the script is:
kCGErrorIllegalArgument : initCGDisplayState: cannot map display interlocks.
kCGErrorIllegalArgument : CGSNewConnection cannot get connection port
Exception in thread "main" java.lang.InternalError: Can't connect to window server - not enough permissions.

Am I forgetting anything? I've tried various things and am getting the same error every time. Thanks.

Did you try the PJAToolkitDemoMacOSX.sh script first ?
Don't use the rtgraphics.jar patch under JDK 1.4 and try it again without the -Djava.awt.headless=true option.

Thanks for the quick feedback. I modified the script to be:

java -Xbootclasspath/a:../lib/pja.jar \
-Djava.awt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-classpath ../lib/pjatools.jar \
ToolkitDemo

I get the following exception:

Toolkit class in use is apple.awt.CToolkit
Exception in thread "main" java.lang.ClassCastException

at ToolkitDemo.ComputeImageFiles(ToolkitDemo.java:138)
at ToolkitDemo.main(ToolkitDemo.java:120)

Any ideas? Thanks,
Chris

I modified the script again -- removed "java" ahead of the "awt" in the 2nd line:

java -Xbootclasspath/a:../lib/pja.jar \
-Dawt.toolkit=com.eteks.awt.PJAToolkit \
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment \
-classpath ../lib/pjatools.jar \
ToolkitDemo


The output is:

Toolkit class in use is com.eteks.awt.PJAToolkit

at ToolkitDemo.ComputeImageFiles(ToolkitDemo.java:157)
at ToolkitDemo.main(ToolkitDemo.java:120)


The demo now correctly creates the images PJAToolkitArcDrawer.gif and PJAToolkitPolygonDrawer.gif. A file named PJAToolkitTextDrawer.gif is created but it is empty.

I have tried the script including and not including the parameters:
-Djava2d.font.usePlatformFont=false \
-Djava.awt.fonts=/my/fonts/folder \

but keep getting the same errors. What should I do to get fonts set correctly?

Thanks,
Chris

Try to run the following command in pja/bin directory :
java -Xbootclasspath/a:../lib/pja.jar -Dawt.toolkit=com.eteks.awt.PJAToolkit -Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment -Duser.home=.. -classpath ../lib/pjatools.jar ToolkitDemo

It will work but with some exceptions of the type :
java.lang.Exception: Stack trace
at java.lang.Thread.dumpStack(Thread.java:1089)
at sun.awt.font.NativeFontWrapper.registerCompositeFont(NativeFontWrapper.java:80)

If you want to avoid these exceptions you may create a "font.properties.Mac OS X" file in pja/lib directory containing the following text (don't forget the spaces in Mac_OS_X file name) :

# font.properties
alias.timesroman=serif
alias.helvetica=sansserif
alias.courier=monospaced
