Start jbpm process through a Servlet
ivanice Oct 27, 2014 12:47 PMHi all,
i have a simple process that execute any script task. I make this with a simple JAR.
Now i want to run this process through a servlet.
I've created a Dynamic web project with a simple servlet into.
how i can start the process?
the code in to the process main of JAR file is:
package com.sample;
import java.util.List;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import org.jbpm.test.JBPMHelper;
import org.kie.api.KieBase;
import org.kie.api.KieServices;
import org.kie.api.runtime.KieContainer;
import org.kie.api.runtime.KieSession;
import org.kie.api.runtime.manager.RuntimeEngine;
import org.kie.api.runtime.manager.RuntimeEnvironmentBuilder;
import org.kie.api.runtime.manager.RuntimeManager;
import org.kie.api.runtime.manager.RuntimeManagerFactory;
public class ProcessMain {
public static void main(String[] args) {
KieServices ks = KieServices.Factory.get();
KieContainer kContainer = ks.getKieClasspathContainer();
KieBase kbase = kContainer.getKieBase("kbase");
RuntimeManager manager = createRuntimeManager(kbase);
RuntimeEngine engine = manager.getRuntimeEngine(null);
KieSession ksession = engine.getKieSession();
ksession.startProcess("com.sample.bpmn.hello");
manager.disposeRuntimeEngine(engine);
System.exit(0);
}
private static RuntimeManager createRuntimeManager(KieBase kbase) {
JBPMHelper.startH2Server();
JBPMHelper.setupDataSource();
EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");
RuntimeEnvironmentBuilder builder = RuntimeEnvironmentBuilder.Factory.get()
.newDefaultBuilder().entityManagerFactory(emf)
.knowledgeBase(kbase);
return RuntimeManagerFactory.Factory.get()
.newSingletonRuntimeManager(builder.get(), "com.sample:example:1.0");
}
}
If I copy the code of the main class into the serlvet class the same i don't know where take the bpmn file into the dynamic web project.
the structure of the web project is:
- ProjectName
+ Jax-ws web services
+Deployment descriptor:
- Java resources
- src
-crc
Servlet.java
+Libraries
+JavaScript Resources
+Build
-WebContent
+META-INF
+WEB-INF
