PJA Toolkit forum

cjustus

Great library... We've used pja before under jdk 1.1, and are now deploying to a site using jdk 1.3...

I've read the FAQ... Getting an error that wasn't listed there:

java.lang.ClassCastException: com.eteks.awt.PJAToolkit
at sun.awt.GlobalCursorManager.getInstance(GlobalCursorManager.java:120)

My classpath has pja.jar ...

Here's my command line (ignore spaces and wrapping... I am 98% certain that it's correct...)

"/usr/lib/j2se/1.3/bin/java" -Xmx128000000 -Xbootclasspath/a:pja.jar -Dawt.
toolkit=com.eteks.awt.PJAToolkit -Djava.awt.graphicsenv=com.eteks.java2d.PJAGrap
hicsEnvironment -Djava.awt.fonts=/usr/lib/j2se/1.3/jre/lib/fonts -Duser.home=. c
om.zerog.lax.LAX "/home/fastbug/FastBugTrack/./FastBugTrack.lax" "/tmp/env.prope
rties.16250"

Here's my version of java (I'm on a Linux Debian 3.0 system):

www:~/FastBugTrack> java -version
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.3.1-02b-FCS)
Java HotSpot(TM) Client VM (build Blackdown-1.3.1_02b-FCS, mixed mode)


I've got a lib directory in my current directory, and the font.properties within this...

Am I missing something? I've searched the forum and haven't seen the classcastexception I'm seeing, and limited Linux problems (which don't seem to match mine :) )...

Any help / suggestions would be appreciated...

Thanks!

Please see the FAQ "Why the methods show () or setVisible () of the class java.awt.Component throws ClassCastException with JDK >= 1.3 ?" : Use addNotify() method instead of show() or setVisible() method, if you can...

Hi Manu

I removed calls to setVisible but get the same exception on calls to removeAll() and add() in my JPanel. I'm maintaining someone else code here so apologies if this is a dumb question.

Thanks
