Hi,
I just migrated to RM 5 and I want to use some RM operators in my Java application. But immediately I have this problem in initializing the RM. Please take a look at my code:
System.setProperty("rapidminer.home", "C:\\Program Files\\Rapid-I\\RapidMiner5");
RapidMiner.init();
I guess the code should be as simple as above.. right? But I received this error message:
2010-07-13 12:08:21 CONFIG: Locale not specified explicitly. Set default locale to US. (RapidMiner.init())
2010-07-13 12:08:21 CONFIG: Initializing I18N (RapidMiner.splashMessage())
2010-07-13 12:08:21 CONFIG: Ensuring RapidMiner Home is set (RapidMiner.splashMessage())

Can anybody please give me a clue about what's wrong here? Do I miss including any library here? I've imported the rapidminer.jar. But this thing 'com/rapid_i/Launcher' is said to be missing. I've tried to include launcher.jar too, but it didn't have any effect.
Thanks in advance,
Wendy
