I'm trying to get JLink112 working on W95 + jdk13+ Mathematica 4.0.

I get the following output when trying to run Scribble.

1. Eval notebook init. No prob.

2.InstallJava[CommandLine -> "c:\\Program Files\\Java\\jdk1.3\\bin\\java"]---->
LinkObject["c:\\Program", 2, 2]
and dos window appears for 5s

3.

In[4]:=
Scribble[]

SetDelayed::"write": "Tag \!\(Times\) in \!\(\[LeftSkeleton] 1 \
\[RightSkeleton]\) is Protected."

SetDelayed::"write": "Tag \!\(Times\) in \!\(\[LeftSkeleton] 1 \
\[RightSkeleton]\) is Protected."

SetDelayed::"write": "Tag \!\(Times\) in \!\(\(\((\(\[LeftSkeleton] 1 \
\[RightSkeleton]\))\)\)[\(\(\[LeftSkeleton] 1 \[RightSkeleton]\)\)]\) is \
Protected."

General::"stop": "Further output of \!\(SetDelayed :: \"write\"\) will be \
suppressed during this calculation."

ToExpression::sntxi: 
   Incomplete expression; more input is needed.

A java window "Scribble" appears with no contents.
I know very little about java but am pretty sure I have jdk13 instaled
correctly.
I've moved the dll and jar file to the correct places.

Thanks for any pointers/help.
