Answer 1

It doesn't work because you're using a 64-bit version of Java, and the SDK you're trying to use contains a 32-bit native library (libbeidlibJava_Wrapper.so.3.5.3). The 64-bit JRE cannot load 32-bit native libraries.

You'll need to use a 32-bit version of Java, or find a version of the SDK that has 64-bit native libraries.
