Re: [rules-users] Why disable properyreactive if amount of properties larger than or equals to 64

Following is the code for building knowledge base:
_kbase = new KnowledgeBaseImpl(new ReteooRuleBase(id, null));
For registering drl code to knowledge base:
Properties props = new Properties();
props.setProperty("drools.dialect.java.compiler", "JANINO");
KnowledgeBuilderConfiguration conf =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(props, null);
final KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder(conf);
kbuilder.add(ResourceFactory.newInputStreamResource(new
ByteArrayInputStream(drlCode.getBytes())), ResourceType.DRL);
_ksession.execute(new GenericCommand<Void>() {
@Override
public Void execute(Context ctxt) {
_ksession.getKieBase().addKnowledgePackages(
kbuilder.getKnowledgePackages());
try {
_kbaseStore.saveKnowledgeBase();
} catch (IOException e) {
throw new RuntimeException(e);
}
return null;
}
});
The drl code:
package test_input
declare input
type : String
end
declare output
taskname : String
end
rule "Rule A"
dialect "mvel"
salience 0
no-loop
when
$input:input(type == "a")
$output:output()
then
modify ($output) {taskname = "Hello"};
end
Stace trace(Not full, others are just the logic in our system, such as
router, find rules, etc.):
