Well, my understanding is that the Personal Java API is only a subset
of the full Java APIs, and I don't know all the details of what is
missing, but I don't have any specific knowledge of any problems
you'll encounter.
Not too, too long ago I was corresponding with a gentleman who had
gotten Jess to run on some sort of Windows CE device using Microsoft's
JVM. We had to muck with the tokenizer a bit because that JVM was
based on an early, buggy version of Microsoft's Java
implementation. Once he got past that I think it worked fine.
