NetBeans 7.1 building error : java.lang.UnsatisfiedLinkError libXtst.so.6: wrong ELF class: ELFCLASS64

Question

I can't build my project using jdk 1.7.0 due to following error on NetBeans 7.1 whereas the same one works well on Eclipse with jdk 1.7.0. Does anyone know how can I resolve this issue ?

Output:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/lib/jvm/jdk.1.7.0/jre/lib/i386/xawt/libmawt.so:         libXtst.so.6: wrong ELF class: ELFCLASS64

That's because you're running a 32bit JVM on a 64bit platform. Install the 64bit JDK and you're off. I have the same errors because I'm trying to run a 32bit JDK. :-)

I can only guess as to why Eclipse works. But it looks to me that this happens when trying to run something using Swing. Netbeans does. Eclipse however runs SWT; its own gui package.
