[rules-users] facing problems while adding a Rule to DROOLS using java client?
Hi,
i am using Guvnor-5.2.0 . Through a simple java client class i wanted to
add
a rule at runtime.
below is the snippet of java code i am using to add a rule.
KnowledgeBase knowledgeBase = createKnowledgeBase();
session = knowledgeBase.newStatefulKnowledgeSession();
logger = KnowledgeRuntimeLoggerFactory.newFileLogger(session,
"log/DroolsSample");
KnowledgeRuntimeLoggerFactory.newConsoleLogger(session);
String ruleDescription = "package com.tcube.atyaf.dto;"+
"import
com.tcube.atyaf.dto.EmployeeDataDTO;" +
"rule \"SimpleDRLRule\""+
" @ID(11003588)"+
" lock-on-active true"+
" salience -11"+
" dialect 'mvel'"+
" when m :
EmployeeDataDTO(empName==\"PC\");"+
" then System.out.println(
\"*************rule executed\");" +
" m.setDesignation( \"Manager
,Additional Duties & Additional hike
!!!\" );"+
" update( m );"+
" end";
byte[] data = ruleDescription.getBytes();
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder(knowledgeBase);
kbuilder.add( ResourceFactory.newClassPathResource("ChangeSet.xml"),
ResourceType.CHANGE_SET );
kbuilder.add( ResourceFactory.newClassPathResource("TestRule.drl"),
ResourceType.DRL);
kbuilder.add(ResourceFactory.newByteArrayResource(data),
ResourceType.DRL);
if(kbuilder.hasErrors()) {
System.out.println( kbuilder.getErrors() );
return;
}
Collection<KnowledgePackage> kpkgs = kbuilder.getKnowledgePackages();
knowledgeBase.addKnowledgePackages( kpkgs );
emp = new EmployeeDataDTO();
emp.setEmpNo(1);
emp.setEmpName("PC");
emp.setAge(29);
emp.setSalary(new BigDecimal("6500"));
session.insert(emp);
session.fireAllRules();
I am getting all the rules executed as per exceptation since it is in the
same session, however the new rules that i have added are not reflected in
Drools-Guvnor UI....
please help me on code for deploying the knowldgeBase/Package(kpkgs) to
Drools-Guvnor UI..
