Setting rapidminer.home, Loading plugins
Hello,
I am getting errors while running rapidminer with the rapidminer-text plugin. Here is a description of the current envrionment and what I have done...
First, rapidminer is installed in /opt/rapidminer without rapidminer-text. The CLASSPATH is set to rapidminer.jar.
/home/user/swe $ echo $CLASSPATH
/opt/rapidminer/lib/rapidminer.jar
This is my short test 'application'
G Nov 9, 2008 6:09:50 PM: Property rapidminer.home is not set. Guessing.
G Nov 9, 2008 6:09:50 PM: Trying base directory of classes (build) '/home/user'...gotcha!
G Nov 9, 2008 6:09:50 PM: ----------------------------------------------------
G Nov 9, 2008 6:09:50 PM: Initialization Settings
G Nov 9, 2008 6:09:50 PM: ----------------------------------------------------
...
===> Why is '/home/user' set as rapidminer.home ('/homer/user'...gotcha)??? There are no rapidminer libraries/files and it isn't the current directory.
Now, the test application sets rapidminer.home:
G Nov 9, 2008 6:23:35 PM: rapidminer.home is '/opt/rapidminer'.

===> It seems that rapidminer extracts the rapidminer-text plugin and overwrites his own classes, because core and plugin use the same package names 'com/rapidminer/...'. I have tested different CLASSPATHs (/opt/rapidminer/lib/rapidminer.jar, /opt/rapidminer/lib/rapidminer.jar:/opt/rapidminer/lib/plugins/rapidminer-text-4.2.jar, ...) without success. Either rapidminer overwrites classes from rapidminer.jar or from rapidminer-text-4.2.jar. What am I doing wrong?
===> It would be very nice if someone could explain the rapidminer.home + loading classes and plugins process in depth.
Thanks a lot
