Trouble using midi sound package

[isum12b]

I'm trying to use midi sound package in eclipse, but every time I run my program, I get the following error:

java.lang.UnsatisfiedLinkError: init_

I'm running ubuntu, and I don't know what I'm supposed to do here. Any help?

Get and install the Sun JDK and scrap gnu, which is also known as "fake Java"
