Hi! I am working with Linux, JDK1.2.2 (SUN) and Java3d (Blackdown) and it works very fine. After I upgraded to JDK1.3 (SUN), my Java3d Apps won't run anymore. The error message is: Exception in thread "main" java.lang.UnsatisfiedLinkError: no J3D (libJ3D.so) in java.library.path at java.lang.Throwable.<init>(Throwable.java:96) <snip/> at golem.visual.WorldVisual.<init>(WorldVisual.java:35) at golem.Start.main(Start.java:47) When i set the java.library.path to the path /usr/lib/jdk1.3/jre/lib/i386/ the error message changed to Exception in thread "main" java.lang.NullPointerException at golem.gui.config.ItemListenerFrame.setVisible(ItemListenerFrame.java:72) at golem.gui.config.DelItemDialog.setVisible(DelItemDialog.java:81) at javax.swing.JInternalFrame.<init>(JInternalFrame.java:272) at golem.gui.config.ItemListenerFrame.<init>(ItemListenerFrame.java:27) at golem.gui.config.DelItemDialog.<init>(DelItemDialog.java:36) at golem.gui.MainGui.<init>(MainGui.java:85) at golem.Start.main(Start.java:55) Has anyone the same problem and is there a solution? thx in advance Sascha Koch =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
