A few tips:
1. Try putting separate commands on separate lines, or, as suggested, put ";" to separate them.
2. Try running the script from command line before running it from cron.
3. When pasting code & commands on this forum, try enclosing them in tags. That makes it
much more readable.
4. You may need to set some environment variables (ie JAVA_HOME) for this script to work properly. You can do this at the top of your crontab settings, or by "source"ing your .bashrc (or other) file directly in the script.
