thanks for your info. I successfully launched BaseX 6.0 with Ubuntu 9.10 (it works with version 8.10 as well), so unfortunately I have no direct answer what could be the issue on your machine. Are you also working Sun's java distribution? I installed Java's JRE version via aptitude (sun-java6-jre)...

I am using Ubuntu 9.10 with the Sun's distribution of java.

...

$ java -version java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) Server VM (build 14.1-b02, mixed mode) user@computer:~$

The current Sun java version for 9.10 is 1.6.0_16 (ends with "_16").

Actually, I take it back. 9.10 comes with "_15" as you reported. I got "_16" from 9.04, before upgrading to 9.10.

$ java -version java version "1.6.0_16" Java(TM) SE Runtime Environment (build 1.6.0_16-b01) Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)

$ apt-cache show sun-java6-jre Package: sun-java6-jre ... Version: 6-16-0ubuntu1.9.04

$ apt-cache show sun-java6-jdk Package: sun-java6-jdk ... Version: 6-16-0ubuntu1.9.04

I downgraded my java version to "_15":

$ java -version java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode, sharing)

but I still get exactly the same error.

I see that your java installation has "sharing" disabled:

Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode, sharing) ^^^^^^^ so I also disabled sharing on mine:

$ java -Xshare:off -version java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode)

but when I run:

$ java -Xshare:off -jar BaseX6.jar

I get exactly the same behavior as before.

...

Feel free to give us more information on your installation. Christian ___________________________

Hello,

I used BaseX GUI before version 6 successfully. Version 6 GUI does not start properly and throws a lot of exceptions. Here is the first one:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException        at sun.java2d.SunGraphics2D.addRenderingHints(SunGraphics2D.java:1295)        at org.basex.gui.layout.BaseXBack.paintComponent(BaseXBack.java:62)        at org.basex.gui.view.ViewContainer.paintComponent(ViewContainer.java:114)        at javax.swing.JComponent.paint(JComponent.java:1029)        at org.basex.gui.view.ViewContainer.paint(ViewContainer.java:269)        at javax.swing.JComponent.paintToOffscreen(JComponent.java:5124)        at javax.swing.BufferStrategyPaintManager.paint(BufferStrategyPaintManager.java:278)        at javax.swing.RepaintManager.paint(RepaintManager.java:1220)        at javax.swing.JComponent._paintImmediately(JComponent.java:5072)        at javax.swing.JComponent.paintImmediately(JComponent.java:4882)        at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:803)        at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:714)        at javax.swing.RepaintManager.seqPaintDirtyRegions(RepaintManager.java:694)        at javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run(SystemEventQueueUtilities.java:128)        at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209)        at java.awt.EventQueue.dispatchEvent(EventQueue.java:597)        at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269)        at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184)        at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174)        at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169)        at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161)        at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)

The main window loads but it is empty. If I hover over the window with my mouse, the buttons start appearing. Anyway, it is unusable. I do not have this issue with 5.7.

Here is the Java version that I use:

$ java -version java version "1.6.0_16" Java(TM) SE Runtime Environment (build 1.6.0_16-b01) Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)

The computer is a 32bit PC with the latest Ubuntu OS.

Thank you for BaseX. Keep up the good work!

Dear Rares,

thanks for your info. Unfortunately, I'm still not sure what causes the problems on your Ubuntu distribution. If you can access and compile the source code of BaseX – http://basex.org/community – it would be great if you could comment out line 63 from the BaseXBack class, which reads as..

// ((Graphics2D) g).addRenderingHints(HINTS);

This did the trick. Thanks a lot!

This method call was introduced with Java 1.6 to support platform independent font rendering – but in your case, it might be the reason for some unexpected behavior.

All the best, Christian
