java.lang.NoClassDefFoundError with JDK1.3.1_13 ! works fine with jdk 1.4.2

Hi All

I am getting this error whenever I use j2ssh tool with JDK1.3.1. And works
fine with JDK1.4.x. Is it true  that j2ssh0.2.2 version doesn't support JDK1.3.1? 

But, the FAQ on sshtool's website claim it supports. Not sure
which version the FAQ was talking about.
