If you want only to try OpenDJ server software, and you do not plan to store any real or important data that you want to keep, then read only this section, or just try out installation without reading any further. Visit the download page, and click the first link on the left for the latest release to start the Java WebStart installer directly from your browser. Java WebStart lets you perform an installation of OpenDJ directory server starting with a click in your web browser, which can be a great way to try OpenDJ directory server for the first time, or to do a quick test installation. You can also upgrade an OpenDJ directory server through the WebStart installer. OpenDJ directory server relies on Java 6, so if your browser picks up an old installation of Java 5 for example, installation can fail. Currently also if you are on a Linux system, you need to get Sun Java 6 before you use OpenDJ directory server. If the WebStart installation does not work in your browser, copy the WebStart URL, ending in QuickSetup.jnlp, from the OpenDJ download page. This is the first link in the list of links for a version of OpenDJ. Next, pass the link as an argument to the javaws command in a terminal window to start the installer. $ export PATH=/path/to/sun-java6/bin:$PATH $ javaws http://www.forgerock.org/downloads/opendj//install/QuickSetup.jnlp The WebStart installer corresponds to what you start if you download OpenDJ-.zip, unzip the file, and then run OpenDJ-/setup (UNIX), OpenDJ-\setup.bat (Windows), or QuickSetup.app (Mac OS X). Java WebStart launches the the QuickSetup wizard, and soon the Welcome screen appears. The Welcome screen appears. Notice in the Server Settings screen that the default ports are 389 or 1389 for LDAP, 4444 for administrative access. You can replicate data for high availability through the Topology Options screen. Generate test data as part of server setup in the Directory Data screen. For a real installation, you adjust JVM parameters for your server, for example to allow OpenDJ to use more memory. Opt to start your server when setup completes. Finally, click Launch Control Panel to check your newly installed server. Run OpenDJ-/bin/control-panel (UNIX), double-click OpenDJ-\bat\control-panel.bat (Windows), or bin/Control Panel.app (Mac OS X) to launch the Control Panel again later.
