Why doesn't work?

ricardomarques May 18, 2007 7:36 AM

Hi guys

I have the following process:

<process-definition
 xmlns="urn:jbpm.org:jpdl-3.1" name="sendmail">
 <start-state name="Inicio">
 <transition name="" to="Send Mail"></transition>
 </start-state>
 <end-state name="Fim"></end-state>
 <node name="Send Mail">
 <action class="test.MailMeActionHandler"></action>
 <transition name="" to="Fim"></transition>
 </node>
</process-definition>

And the following action handler:

package pep.test;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;
//import java.util.Properties;
//import javax.mail.*;
//import javax.mail.internet.*;
import java.io.*;

public class MailMeActionHandler implements ActionHandler {

 private static final long serialVersionUID = 1L;

 public void execute(ExecutionContext context) throws Exception {


 /* Tenta enviar o e-mail*/

 String host = "smtp.myserver.com";
 String from = "ricardo.marques@myserver.com";
 String to = "ricardo.marques@myserver.com";

 try {
 // Get system properties
 Properties props = System.getProperties();

 // Setup mail server
 Authenticator auth = new PopupAuthenticator();
 props.put("mail.smtp.host", host);
 props.put("mail.smtp.auth", "true");

 // Get session
 Session session = Session.getInstance(props, auth);
 session.setDebug(true);
 //session.setDebug(true);



 // Define message
 MimeMessage message = new MimeMessage(session);


 // Set the from address
 message.setFrom(new InternetAddress(from,"Ricardo Marques"));

 // Set the to address
 message.addRecipient(Message.RecipientType.TO,new InternetAddress(to,"Ricardo Marques"));

 // Set the subject
 message.setSubject("Hello JavaMail");

 // Set the content
 message.setText("Welcome to JavaMail");

 // Send message
 Transport.send(message);
 System.out.println("OK Man");
 }
 catch (Exception e) {
 e.printStackTrace();
 }

 context.leaveNode();

 }

 static class PopupAuthenticator extends Authenticator {
 public PasswordAuthentication getPasswordAuthentication() {
 return new PasswordAuthentication("rmarques@myserver.com", "******");
 }
 }

}

But just can't see the result of the execution, or any kind of error. On the process instances table, it appears a record about the execution, but nothing else.

The mail code, detach from the jbpm enviromnent, it works, so I suppose that should work on the enviroment.

I want to start the process and receive a e-mail.

Please need some help..!

the action is in a place where it does not do anything. It is neither related to the node as a node implementation, nor to an event, nor to a transition, nor to a timer. Look at the testcases and examples how to do this.

Ok, stupid not to use the preview; some < .. > I used are hidden in my previous reply.

So:

The package name isn't a problem, my mistake and I paste the code here.

Regarding how the process is design, i had look at the websale example, particulary to this part:

<node name="update books"> <action class="org.jbpm.websale.UpdateBooks"> <msg>accountancy application is now informed of the payment</msg> </action> <transition to="salejoin" /> </node>

I suspect that the problem has something doing with i'm using the class NewProcessInstanceCommand to start an execution, but something more must miss.

Do I need to signal a instance to start even i had a start node?

help needed!

ok... sorry I was wrong... that might indeed work (I still had the old format in mind, shame on me)

Can you analyse the debug output and see what really happens?

ricardomarques May 21, 2007 7:37 AM (in response to ricardomarques)

BTW, i'm trying to isolate the problem, now i've tried to execute the process from another way, this time using StartProcessInstanceCommand.

Using this code:

Properties props = System.getProperties();
 try {

 props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
 props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
 props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

 Context ctx = new InitialContext(props);

 Object obj = ctx.lookup("CommandService");

 CommandServiceRemoteHome remoteCommandService = (CommandServiceRemoteHome) javax.rmi.PortableRemoteObject.narrow(obj,CommandServiceRemoteHome.class);
 CommandServiceRemote commandService = remoteCommandService.create();

 StartProcessInstanceCommand cmd = new StartProcessInstanceCommand();

 cmd.setProcessName("send mail 4");
 cmd.setCreateStartTask(false);
 cmd.setActorId("grover");


 System.out.println("RETURNING OBJECT: " + commandService.execute(cmd).toString());

 commandService.remove();
 ctx.close();

I get this exception:
