I'm close to giving up! No matter what I do I get the noclassdeffound error. I can't get anything that uses Drools to work outside of eclipse. I've now tried using javac and I still get errors, the first is: ---------------------------------------------------------------------------------------------------------------- [javac] [search path for source files: [/Users/mark/Documents/eclipse/drools-test-mini/src]] [javac] [search path for class files: [... (lots of paths removed) ... /Users/mark/Documents/eclipse/drools-test-mini/JAR ...]] ... [javac] /Users/mark/Documents/eclipse/drools-test-mini/src/com/mda/dt/DroolsTest.java:6: package org.drools does not exist [javac] import org.drools.RuleBase; [javac] ^ ---------------------------------------------------------------------------------------------------------------- But the directory '/Users/mark/Documents/eclipse/drools-test-mini/JAR' has the following: antlr-runtime-3.0.jar drools-compiler-4.0.1.jar mvel14-1.2rc4rv908.jar xpp3_min-1.1.3.4.O.jar core-3.2.3.v_686_R32x.jar drools-core-4.0.1.jar xercesImpl-2.4.0.jar xstream-1.2.2.jar drools-ant-4.0.1.jar jxl-2.4.2.jar xml-apis-1.0.b2.jar The org.drools.RuleBase is in the drools-core jar file so what is it that I am doing wrong?

Ok, so why not make this information (dependencies required to build outside Eclipse) available as part of the examples download? I mean, how many times do you want to answer this same question?

Okay, many thanks for this. Firstly, I apologise if I am asking these questions in the wrong place, I don't want to waste people's time but it is *very* frustrating for new users when problems like this occur. I scoured the documentation, the quick-start guide, the faqs and searched on the internet but could find no help. From some of the responses I have received from the various sources it seems that I am not the only person hitting these issues. Secondly, it looks like my error is that I set the CLASSPATH to point at the directories, .../JAR and .../JAR/lib, not each individual .jar file as in your batch file. I had tried it with just the small set of .jars that you have and, as far as I can tell, the only difference is using the directories in the CLASSPATH variable. I'll change that in mine and see what happens but I can compile and run the example you sent which is fantastic.

Many thanks again and sorry for being stupid.

That still hasn't fixed it. I can now compile it with javac without errors but it still gives noclassdeffound error when it runs. At least I now have your example that does work, so I am going to modify it bit by bit until I find out where my mistake is. My initial one was created with the wizard in eclipse so I'm not sure what has happened! Anyway, I will persevere and post the results in case anyone else needs pointers. Thanks all. Mark.
