1. Sun JDK 1.5 or higher. You can download the Java SE Development Kit (JDK) from the Sun website.
2. Note: Once the JDK is installed, you will need to set the JAVA_HOME environment variable, pointing to the root directory of the JDK. Some JDK installers set this automatically (check by typing 'echo %JAVA_HOME%' in a DOS prompt, or 'echo $JAVA_HOME' in a shell). If it is not set, please see Setting JAVA_HOME.
3. J2EE 1.4 application server or a Servlet 2.4 web container. NOTE: Crowd ships with Apache Tomcat (5.5.x).
4. JDBC-compliant database that is supported by Hibernate. NOTE: Crowd ships with a built-in HSQL database, which is fine for evaulation purposes. For production environments we recommend configuring Crowd to use an external database.
5. If you are deploying a WAR installation, ensure that the following JAR files are deployed in the shared lib folder on the application server:
   • JTA (Java Transaction API)

     The JTA specifies standard Java interfaces between a transaction manager and the parties involved in a distributed transaction system: the resource manager, the application server, and the transactional applications. Refer to the Sun documentation for more information.

   • JavaMail classes
   • Java Beans Activation Framework (for those using Sun JDK 1.5.x only, this is included in JDK 1.6)

All of these JAR files are available in the Crowd Standalone Distribution zip file, available on the Crowd download centre — jta-1.0.1B.jar, mail-1.4.jar and activation-1.1.jar in CROWD\apache-tomcat-5.5.20\common\lib.
