jbpm-drools integration ----------------------- Key: DROOLS-168 URL: https://issues.jboss.org/browse/DROOLS-168 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Environment: windows operating system(xp) Reporter: sangeetharaman c Assignee: Mario Fusco Labels: jbpm-drools, jbpm-drools-inte i am integrating jbpm process with drools. In my case during a transition from one process to another i have added an action which performs following : package com.sample.action; import java.io.InputStreamReader; import java.io.Reader; import org.apache.log4j.Logger; import org.drools.RuleBase; import org.drools.RuleBaseConfiguration; import org.drools.RuleBaseFactory; import org.drools.WorkingMemory; import org.drools.compiler.PackageBuilder; import org.drools.compiler.PackageBuilderConfiguration; import org.drools.rule.Package; import org.jbpm.graph.def.ActionHandler; import org.jbpm.graph.exe.ExecutionContext; public class TestDroolActionHandler implements ActionHandler { /** * */ private static final long serialVersionUID = 1L; static Logger logger = Logger.getLogger(TestDroolActionHandler.class); @Override public void execute(ExecutionContext executionContext) throws Exception { // TODO Auto-generated method stub try { RuleBase ruleBase = readRule(); WorkingMemory workingMemory = ruleBase.newStatefulSession(); Message message = new Message(); message.setMessage( "Hello World" ); message.setStatus( Message.HELLO ); workingMemory.insert( message ); workingMemory.fireAllRules(); } catch (Throwable t) { t.printStackTrace(); } } private RuleBase readRule() throws Exception { Reader source = new InputStreamReader( TestDroolActionHandler.class.getResourceAsStream( "/Sample.drl" ) ); //Use package builder to build up a rule package. ClassLoader classLoader = this.getClass().getClassLoader(); PackageBuilderConfiguration configuration = new PackageBuilderConfiguration(); configuration.setClassLoader(classLoader); PackageBuilder builder = new PackageBuilder(configuration); //this wil parse and compile in one step builder.addPackageFromDrl( source ); //get the compiled package (which is serializable) Package pkg = builder.getPackage(); //add the package to a rulebase (deploy the rule package). RuleBaseConfiguration ruleBaseConfiguration = new RuleBaseConfiguration(); ruleBaseConfiguration.setClassLoader(classLoader); RuleBase ruleBase = RuleBaseFactory.newRuleBase(ruleBaseConfiguration); ruleBase.addPackage( pkg ); return ruleBase; } public static class Message { public static final int HELLO = 0; public static final int GOODBYE = 1; private String message; private int status; public String getMessage() { return this.message; } public void setMessage(String message) { this.message = message; } public int getStatus() { return this.status; } public void setStatus( int status ) { this.status = status; } } } this code reads .drl file: package com.sample.action import com.sample.action.TestDroolActionHandler.Message; 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 ); update( m ); end rule "GoodBye" no-loop true when m : Message( status == Message.GOODBYE, message : message ) then System.out.println( message ); m.setMessage( message ); end i get the following error: 19:05:02,206 ERROR [STDERR] org.drools.rule.InvalidRulePackage: Unable to resolve ObjectType 'Message' : [Rule name=Hello World, agendaGroup=MAIN, salience=0, no-loop=false] Unable to resolve ObjectType 'Message' : [Rule name=GoodBye, agendaGroup=MAIN, salience=0, no-loop=true] com.sample.action.TestDroolActionHandler.MessageRule Compilation error : [Rule name=GoodBye, agendaGroup=MAIN, salience=0, no-loop=true] com/sample/action/Rule_GoodBye_0.java (2:35) : The import com.sample.action.TestDroolActionHandler.Message cannot be resolved com/sample/action/Rule_GoodBye_0.java (7:294) : message cannot be resolved com/sample/action/Rule_GoodBye_0.java (8:309) : m cannot be resolved com/sample/action/Rule_GoodBye_0.java (8:323) : message cannot be resolved Rule Compilation error : [Rule name=Hello World, agendaGroup=MAIN, salience=0, no-loop=false] com/sample/action/Rule_Hello_World_0.java (1:0) : The type com.sample.action.TestDroolActionHandler$Message cannot be resolved.
