Build, Dependencies & Source Code

Internationalization (i18n)

What languages are supported?

The supported languages are English, German, Simplified Chinese and Japanese.

Can I get Stardust in another language?

A: Stardust's portal, error messages and Eclipse plugins are fully i18ned and can be translated by anyone into additional languages. One only has to create and translate the corresponding resource bundles. We found a convenient way to do this using excelbundle and create a script to make the rountrip (translation-update-review-adjustment) easier. This way also non technical people can work on the translation in an Excel sheet.

Trouble Shooting

How can I prevent OutOfMemoryErrors on Tomcat?

The default Tomcat settings (in a RAD scenario) do not allocate much memory. Hence the application may run often out of memory quite frequently. The console log will often throw a java.lang.OutOfMemoryError exception. To avoid this, just add a different memory settings in the Tomcat launch configuration:

Servers > Open Launch Configuration > Arguments > VM arguments > at the very bottom add >

-Xms128m -Xmx512m -XX:MaxPermSize=128m

On a standalone server (outside eclipse RAD environment) start tomcat using:

set JAVA_OPTS=-Xms128m -Xmx512m -XX:MaxPermSize=128m
catalina.bat run

How can I browse the Jackrabbit repository contents?

The easiest way to browse the Jackrabbit repository is to use WebDAV and configure the repository as a network drive under Windows. You will need to ensure that the WebDAV servlets (Simple WebDAV and JCR over WebDAV)  are configured properly in the web.xml of your web application. You can then use a command like the following to map the repository as a network drive:

net use t: "http://<hostname>:<port>/<context-root>/jackrabbit/repository/default/ipp-repository" /User:<jcr-user> <jcr-password>

The <jcr-user> and <jcr-password> can be obtained by looking up the values specified in the jackrabbit-jcr-context.xml file.

To browse the Jackrabbit tree and look up the node property values you can use a tool like JCR Browser ( This tool provides options to connect to the repository over RMI/WebDAV etc.
