Aloha!

I'm trying to run my first Java app under Eclipse on Mac OS 10.6.8. I'm getting

Exception in thread "main" java.lang.InternalError: Can't connect to window server - not enough permissions.
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1827)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1724)
at java.lang.Runtime.loadLibrary0(Runtime.java:823)
at java.lang.System.loadLibrary(System.java:1045)
at sun.security.action.LoadLibraryAction.run(LoadLibraryAction.java:50)
at java.security.AccessController.doPrivileged(Native Method)

at java.awt.Component.<clinit>(Component.java:566)
at crossmatch.Isimo.<init>(Isimo.java:37)
at crossmatch.Isimo.main(Isimo.java:72)

where line 37 is

BoardFrame frame = new BoardFrame();

BoardFrame extends java.awt.Frame. What permissions does it want? Other compiled Java apps run fine.

Hi, Have you tried using update site or installing plug in on mac. I am getting provision and NoHTTPConnectionException. If you ever faced this issue then please let me know the solution.

Thank you for the suggestions! I decided to use NetBeans. I'm sorry but I don't know anything about your issue.

Few others have seen the same exception
https://github.com/overviewer/minecraft-biome-extractor/issues/1

http://lists.apple.com/archives/java-dev/2004/dec/msg00613.html

The solution seems to be running awt in headless mode i.e. use
-Djava.awt.headless=true while launching the java program.
