I think the compiler jar failed to build perhaps due to the error?
Edson Tirelli's message received 4/9/2008 6:14 PM:
After the build, you can find the jars in: drools-core/target drools-compiler/target Their version must always match or you will end up with other problems. []s Edson 2008/4/9 Scott Reed <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>>: I built it but can only find the core jar file, nothing for the compiler. With just the core jar replaced, I still get the NPE. Edson Tirelli's message received 4/9/2008 2:24 PM:Nope, only source code. Problem is 4.0.x will be released as 4.0.7, and if your specific problem is fixed and you are not able to test before the release, it will have to wait 4.0.8. <http://4.0.8.> All you need to build drools is java, maven and ant. Can you set this up? []s Edson 2008/4/9 Scott Reed <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>>: Glad to hear that. However, I am not set up to do my own drools build and it looks like the link you sent is for the source. Is there a set of jars for 4.0.x that I can test from? Here is what I am using now: antlr-runtime-3.0.jar core-3.2.3.v_686_R32x.jar drools-compiler-4.0.4.jar drools-core-4.0.4.jar mvel14-1.2.21.jar xstream-1.2.2.jar Thanks, Scott Edson Tirelli's message received 4/9/2008 11:46 AM:Scott, I believe this is fixed already. Can you try it out and let us know? http://anonsvn.labs.jboss.com/labs/jbossrules/branches/4.0.x/ []s Edson 2008/4/8 Scott Reed <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>>: Sorry, the NPE is in ReteTuple.get(Declaration) Scott Reed's message received 4/8/2008 7:38 PM: Running Drools 4.0.3, on Win 2k sp4, JDK 1.6.0_03. I am getting this exception after the debugger shows execution has gone past the end of the rule. The exception is occurring in ReteTuple.get(Descriptor). I believe the descriptor argument is null. Can anyone suggest why this might be happening and what I can do to avoid it?
