It seems that you have wrong bootclasspath. Try to set that.
And strings is your friend, string jamvm will show you where is it
looking for libs.
And, of course, when building jamvm you have to tell it where to look
for classpath using --with-classpath-install-dir config parameter.
I was using jamvm 1.4.5, and then tried cacao 0.98.
jamvm starts in half time, and uses half of memory compared to cacao,
but runs at half the speed of cacao...
