Memory: 128 MB of RAM for demonstration; 512 MB for optimum application Prozessor (PC): Intel or AMD with 300 MHz for demonstration; 800 MHz for optimum application Hard disk space: 100MB (without JDK) Software: Sun 1.4.x; if need is Apache Tomcat 4.1.x.

In case of using Apache Tomcat as Webserver or servlet container, the memory for Java processes should be increased if expecting a lot of parallel requests or processing a lot of data. Corresponding modifications could be done in catalina.sh / catalina.bat (Tomcat 4.x) or when starting the tomcat:

java -Xms100m -Xmx500m -jar -Duser.dir="C:\Programme\ApacheGroup\Tomcat4.1" "C:\Programme\ApacheGroup\Tomcat4.1\bin\bootstrap.jar" start
