AbstractMethodError using Eclipse IDE

[mharris888]

Hello,

I receive the following exception when attempting to run the HelloWorldWind.java file in the package gov.nasa.worldwindx.examples

Exception in thread "main" java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V

I am using the Eclipse IDE Version: Indigo Service Release 1 Build id: 20110916-0149
JDK point release 1.7.0_05
JRE7

I have checked the following posts:

Thanks for your help in advance:

After a few days of chasing this I have some updates to do. I live in Scotland and the sun is out, so I'm going to have fun instead.

I believe I might have a problem with an incorrect version of jogl for my 64 bit machine that when upgraded to jogl-1.1.0-windows-amd64 throws invalid type errors in the TextRenderer due to the change:

TextureRenderer, Overlay and TextRenderer. The TextureRenderer
supports drawing into an OpenGL texture using Java 2D. The Overlay
class provides a convenient Java 2D-based overlay on top of an
arbitrary GLDrawable. The TextRenderer class supports drawing of
Java 2D text into an OpenGL context.

Does anyone know which version of jogl I use for a 64 bit windows machine that is also compatible with Worldwind?

Any help would be appreciated.

Thank you,

M

Welcome to the forum.

You need to use the "Search" function more.
What is required, where to download the 64bit jogl, 64bit java, etc. has been covered several times.

I went back to 32bit as the apps can be run on 32bit and 64bit computers.
Other than a bigger heap space, which you shouldn't need if your code is optimized, what advantage is there to 64bit?

Some prefer nb but I do not.

You need JOGL 1.1.1. You can get it here: http://worldwind.arc.nasa.gov/java/jogl/webstart/

If you're on Windows 64, download jogl.jar, jogl-natives-windows-amd64.jar, and gluegen-rt-natives-windows-amd64.jar.

Thank you for the posts. There were a few errors when importing into Eclipse when solely following the worldwind wiki page. http://www.worldwindcentral.com/wiki/WWJava_in_Eclipse

I do not know if it was a change with Eclipse or a change with the way that WWJ is packaged that has caused it; however I will be happy to write up the steps I went through to install the 64 bit version if you think it is necessary?

[nlneilson]

When I tried 64 bit is all that was required was the 64bit java and the 64bit jogl files to run. In Eclipse I just set the path to those.

If your steps include more than that a write up would help others.

Good you got it sorted out and letting others know.

On import I received the AbstractMethodError detailed above until I had removed all but the following jars from the class path under Properties>Java Build Path.

gdal.jar
gluegen-rt-natives-windows-amd64.jar
gluegen-rt.jar
jogl-natives-windows-amd64.jar
jogl.jar
junit.jar
plugin.jar

After using jogl1.1.1 it works fine.
