Ok, Thanks for the help on the drl syntax. So this works. *rule* "UCCnet_DVE_Depth_All" *when* catalogObject : CatalogObject( ) *eval*( catalogObject.getElementValue("depth") == *null* || catalogObject.getElementValue("depth") == "" ) *then* logWriter.logDebug("Package Depth is Blank"); *end* But how do I get the drl parser to accept something like this: *rule* "UCCnet_DVE_Depth_All" *when* catalogObject : CatalogObject( ) String s = catalogObject.getElementValue("depth"); *eval*( s == *null* || s == "" ) *then* logWriter.logDebug("Package Depth is Blank"); *end* I am getting an Unexpected token 's' InvalidRulePackage _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
