[SOLVED] Trying to run RapidMiner (Unuk rev 708) in Eclipse
Following the instructions in "How to Extend RapidMiner 5", I've grabbed the RapidMiner_Extension_Template and RapidMiner_Extension_Tutorial and then RapidMiner_Unuk (rev 708), all within Eclipse (Juno SR1). It took a lot of jar-adding to get the RapidMiner_Unuk project to compile, but it finally does. Now, when I try to run RapidMinerGUI as a Java application, I get this exception:
By comparison, a similar Eclipse project I set up using the RapidMiner 5.2.008 distribution's src directory runs just fine although it does not have a resources/ directory. One key difference is that I did add the RapidMiner 5.2.008 distribution's lib/rapidminer.jar to the project's Java build path. If I try the same trick with RapidMiner_Unuk, it sorta works: I get to the welcome window but the icons are replaced by "gui.action.welcome.*" strings (clearly it can't find its resources). The log is as follows:
This happens in the RapidMiner class's initializer, when it hits this line:
Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.lang.NullPointerException

at java.io.InputStreamReader.<init>(Unknown Source)
at java.util.Scanner.<init>(Unknown Source)
at com.rapidminer.RapidMiner.<clinit>(RapidMiner.java:311)
Apparently it can't find "/com/rapidminer/resources/i18n/language_definitions.txt", although I can't see why, since the file is indeed present in the "resources/" subdirectory of the Eclipse project directory (RapidMiner_Unuk). If I wrap the offending lines in a try-catch block (which is acceptable, it just means the language defaults to English), initialization goes on a bit longer, then it chokes on another resource-fetch, in the LogService initializer:
Scanner scanLanguageDefs = new Scanner(RapidMiner.class.getResourceAsStream("/com/rapidminer/resources/i18n/language_definitions.txt"));
Again, the resource "resources/com/rapidminer/resources/i18n/LogMessages.properties" is present.
private static final Logger GLOBAL_LOGGER = Logger.getLogger("com.rapidminer", "com.rapidminer.resources.i18n.LogMessages");

Hi,
the sourcecode contains a .project file from Eclipse. Did you let Eclipse use that? There should be no configuration at all necessary when checking RM out via SVN in Eclipse.
Regards,

Silly me. The tarball did include that file (and the others starting with a period) but it got dropped when they were copied to the Eclipse project. Windows Explorer won't copy hidden files, and Linux hides files whose names start with periods. Windows Explorer even has problems naming files with initial periods.Marco Boeck wrote:

Any way, it works now! Thanks.0
