This should work, though the processing would happen before displaying the output:
Code:
if java ... > TEMP.FILE; then
    # Process success
fi
cat TEMP.FILE | tee -a $PathToLog
rm -f TEMP.FILE

Or this would keep things in order:
Code:
java ... > TEMP.FILE
result=$?
cat TEMP.FILE | tee -a $PathToLog
rm -f TEMP.FILE
if [ $result = 0 ]; then
    # Process success
fi

Or, if the processing produces no output, you might do this:
Code:
if java ... ; then
    # Process success
fi | tee -a $PathToLog
