[rules-users] eclipse-jdtcore.jar

[Augusto Rodriguez]

Hi Corneil,

Unluckily I've seen that error more often that I would like. It's not a 
bug in drools, but is related to the dependencies of the drools-compiler.

There's a big chance that you have a different version of the JDT core 
jar in your classpath (drools depends on version 3.2.3 - the filename of 
that jar is core-3.2.3.v_686_R32x.jar). This jar is used by drools to 
compile the rules.

I hope this helps you to solve this issue.


Cheers,
Augusto
