If you're having trouble starting screen-scraper in server mode or running scraping sessions in server mode run the following command in a batch or shell script as an alternate way to start the server.
jre/bin/java -Xmx128M -jar screen-scraper.jar --start-server --interactive
Running the server in this way does two things to help you troubleshoot your scraping sessions and the program itself.

1. Bypasses the wrapper.exe program, running the screen-scraper.jar file directly.
2. Writes out to the console/command window any messages sent to standard out.

You also have two commands you can use within the console/command window:

1. status - Indicates the number of sessions running as "clients currently connected".
2. quit - Stops the server.
