Code:
if java ... ; then
# Process success
fi | tee -a $PathToLog
This works - after a first test - fine for me, the 2 other solutions don't fit my needs for this script, but maybe i'll use them another time Smilie. Thanks a lot!

After some own research today, i came across this solution:
Code:
set -o pipefail

if ( java .... ) | tee -a $PathToLog
then  # Process succes
fi

Can you think of what solution of these two would be the best one?

thanks and greets
