I wanted to use the functionality of a class, which uses the NodeLogger, outside from KNIME (within a simple Eclipse Java Project). Is that possible? Would I have to set up that log4j-thing (How? I don't have a clue how that works). Or is there any other trick (as I don't need that log-messages). Any other suggestions?
In principle it should work if you have the knime-core.jar in your classpath. You should also set the system property knime.log4j.config.disabled=true, otherwise the NodeLogger tries to initialize all kinds of stuff which may not work outside of Eclipse. You don't need an explicit log4j configuration the standard one should do it.
