On the serverside, the following warning is shown:
06:36:14,175 INFO [de.rapidanalytics.web.servlet.PluginServlet] Request: /resources.xml
06:36:14,179 WARNING [com.rapidminer] XML transformer does not support indentation: java.lang.IllegalArgumentException: Not supported: indent-number
This is with the JBoss bundle of RA, running on Ubuntu 10.04.
The version of RapidMiner in RapidAnalytics is incompatible with extensions in the standalone RapidMiner.
On startup it would try to load the extensions stored in ~/.RapidMiner5.
Once this directory was removed, RapidMiner would complete startup when initiated from webstart in RapidAnalytics
