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.

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.
  
      

This is standard Java, I don't think this is something we should be 
explaining, as it's done in hundreds of places around the net.
    

Many thanks again and sorry for being stupid.
  
      

np, stupid Qs are allowed (we get lots of them), but you have to expect 
a bit ot stick with them - call it character building ;) Good luck.

sigh.... I've zipped up droools-examples eclipse project with a 
populated lib directory and a dos .bat file. Should be enough to get you 
over the basics of java classpath configuration:

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?
