Various Java issues. (OpenJDK's JRE7 and JDK7)

Hello,

I'm having some trouble with both the java browser plugins and java itself if seems. I'm on a 64 bit system.

Minecraft:

Minecraft will load up until login. Running the jar file in the terminal gives this message:

Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: /home/harley/.minecraft/bin/natives/liblwjgl.so: /home/harley/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

        at net.minecraft.client.Minecraft.run(SourceFile:657)
        at java.lang.Thread.run(Thread.java:722)

It appears this stems from 32 bit libraries on a 64 bit system according to the error message. How can this be fixed? Note that both the browser applet and the standalone jar file version of minecraft are non-functional.

Runescape:
Safe Mode and likely software mode work in runescape and the game appears fully functional in those modes. It will give an error message when I attempt to use the OpenGL mode, however. As this is purely browser based, it's much harder for me to give the forums any terminal output to aid in this issue.

Both of these games utilise OpenGL. Minecraft is dependent on OpenGL and will not work at all and Runescape will only work on safe mode without OpenGL. OpenGL does not seem to be working with Java on my system. I have the latest NVIDIA drivers (proprietary) installed on my system (302.17-4) from the [extra] repository. I used the nvidia-xconfig tool to configure X to use the nvidia drivers. On the other hand I have no way to test 3D acceleration at this time.

Any help on this matter is greatly appreciated.

Thanks,
Dragos

is your multilib enabled & your system up-to-date ?

That error has nothing to do with multilib and is easily fixed.

Make a launcher script for Minecraft in which you export this before launching Minecraft:

export LD_LIBRARY_PATH=/usr/lib/jvm/java-7-openjdk/jre/lib/amd64
