Error loading/compiling rules in weblogic

[paramsevak]

I am trying to load/compile and run rules within a weblogic J2ee Container and am unfortunately running into a problem where no exceptions are being thrown and the server is forcefully shutdown. I am able to get it working, even with the JANINO compiler, outside of the j2ee container.

The following is a code snippet I am trying to run from within a action in the J2ee container

PaymentRulesService paymentService = new PaymentRulesService();// LookupService.getPaymentRulesService( data.getServletContext() );

PackageBuilderConfiguration pkgBuilderCfg = new PackageBuilderConfiguration();
pkgBuilderCfg.setJavaLanguageLevel("1.4");
pkgBuilderCfg.setCompiler(1);
PackageBuilder builder = new PackageBuilder(pkgBuilderCfg);
builder.addPackageFromDrl((new InputStreamReader(new FileInputStream("c:\\Sample.drl"))) );
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage( builder.getPackage() );
paymentService.setRuleBase(ruleBase);
ArrayList objectArray = new ArrayList();
//go !
Message message = new Message();

message.setMessage( "Hello World" );
message.setStatus( Message.HELLO );
objectArray.add( message );

String ruleResult = paymentService.firePaymentRules( objectArray );


I have colored the line where the error occurs in red. Also the following is the drl file. It is a slight modification of the Hello World example.

package com.sample.rules.resource

import com.sample.DroolsTest.Message;
global java.lang.String PAYMENT_RESULT;

rule "Hello World"
when
m : Message( status == Message.HELLO, message : message )
then
System.out.println( message );
m.setMessage( "Goodbye cruel world" );
m.setStatus( Message.GOODBYE );
PAYMENT_RESULT = "Goodbye cruel world";
modify( m );
end

rule "GoodBye"
no-loop true
when
m : Message( status == Message.GOODBYE, message : message )
then
System.out.println( message );
m.setMessage( message+" tests" );
PAYMENT_RESULT = message+" tests";

end

I have tried to keep everything simple. It is extremely strange how this works perfectly fine when I run this outside of weblgic.


Any Help is greatly appreciated.

Thanks
