Drools Exception

[bindhu]

Hi All,

I'm facing a problem when i have both *.drl and *.dsl. The following is the exception i'm facing.

java.lang.IllegalArgumentException: Unable to use expander. Make sure a expander or dsl config is being passed to the parser. [ExpanderResolver was not set].
at org.drools.lang.RuleParser.expander(Unknown Source)

at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source)
at com.livetrial.CreditExample.main(CreditExample.java:24)
Exception in thread "main"


In the main java class, i have the below codes:

builder.addPackageFromDrl( new InputStreamReader(CreditExample.class.getResourceAsStream("/credit.drl" )) );
builder.addPackageFromDrl( new InputStreamReader(CreditExample.class.getResourceAsStream("/credit.dsl" )) );

Please guide me on how to resolve this problem.


Thanks
