Error sending email in jbpm-4.2

[cmjhingeniero]

Hi

Currently I have a  problem, what happens is that I want to notify a user by e-mail that  has a task. I searched lot on the web but I can not  find the problem. I'm using jbpm-4.2 with  apache-tomcat-6.0

Example process

  <start g="13,13,48,48" name="inicio">
        <transition to="enviar"/>
   </start>

  <mail g="274,755,86,40" name="enviar">
        <to addresses="[e-mail]"/>
        <cc addresses="[e-mail]"/>
        <subject>Prueba</subject>
        <text>Prueba</text>
        <transition to="despacho caf"/>
   </mail>
  
   <task candidate-groups="caf" form="com/procesos/interfaces/nCaf.jsp" g="352,695,92,52" name="despacho caf">
        <notification>
            <to addresses="[e-mail]"/>
            <cc addresses="[e-mail]"/>
            <subject>Prueba 2</subject>
            <text>Prueba 2</text>
        </notification>
        <transition to="fin"/>
   </task>

<end g="1082,228,48,48" name="fin"/>

Hi Carlos,

I googled on net.  And somebody said that it could be caused by wrong version of email.  I suggest you try the mail.jar included in jBPM distribution.

Hi HuiSheng

thanks  for responding in the classpath if you are activation.jar and mail.jar

[cmjhingeniero]

I could not solve the  problem, so I consulted the web is in the configuration of tomcat. If anyone can help me I  appreciate it. I tried sending email  from a normal java method and I get the following error:

javax.mail.NoSuchProviderException:  smtp

Source  Code Java:

public void send(){
        MimeMultipart multipart = new MimeMultipart();
        Properties properties = new Properties();
        properties.put("mail.smtp.host", "10.1.1.20");
        Session session = Session.getDefaultInstance(properties, null);
        session.setDebug(true);
        try {
            MimeMessage msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress("[e-mail]"));
            msg.setRecipients(Message.RecipientType.TO, "[e-mail]");
            msg.setSubject("PROBANDO");
            msg.setSentDate(new Date());
            MimeBodyPart mbp = new MimeBodyPart();
            mbp.setText("PROBANDO");
            multipart.addBodyPart(mbp);
            msg.setContent(multipart);
            Transport t = session.getTransport("smtp");
            t.connect();
            Transport.send(msg);
            t.close();
            System.out.println("===>Correo Enviado...");
        }
        catch (Exception mex){
            System.out.println("===>Error MailSender.send() = "+mex);
        }
    }

Thanks

First of all please add :

mail.debug set to true to mail properties:

Properties properties = new Properties();
properties.put("mail.smtp.host", "10.1.1.20");
properties.put("mail.debug", "true");

that should print quite some information. Please attach the log file to the discussion.

What version of mail.jar are you using?

[cmjhingeniero]

Thanks  for responding. The mail.jar I'm using is the one who brings jbpm-4.2  package. Associate the image with the error found

I appreciate any information that you can give me

[swiderski.maciej]

Could you describe a bit your environment setup?

It seems like some class loader issues. Please make sure that jbpm and mail libraries are loaded by the same class loader.

I  installed the jbpm-4.2 package and install it on tomcat with  demo.setup.tomcat I check in the lib folder of apache-tomcat libraries  were the activation.jar and mail.jar Also in the lib folder of src-4.2  jbpm is the activation.jar and mail.jar libraries

Thanks for your  help

I  updated the version of mail.jar to Tomcat 1.4.3 I have reinstalled with  reinstall.tomcat.and.jbpm but the error persists. I have found in a  different forum following the error I get:

Forum Response:
"Undoubtedly  this is a configuration error in your production Tomcat server.
If you're  Including mail.jar in your web application Tomcat Then Most Likely
Also has a  version of mail.jar that's somehow Causing the problem. Possibly there's a  problem with the Tomcat ClassLoader That makes Used in
Unable to look it  up the file That resource providers configure the protocol "

I do not know  what to check in the apache-tomcat.6.0.20
I have four days and I could not find the solution thank any  help

Thanks

did you try removing the mail.jar & activation.jar from the tomcat/lib directory and just keep the ones in your application's lib directory?

and maybe you should give tomcat 6.0.26 a try
