Any idea.

Hi ,

Now i can get you.
So how can i write a class for mail with attachment ?

Is the class " org.activiti.engine.impl.bpmn.behavior.MailActivityBehavior" enough or which class i should use for using Commons email technique.

For attachment using commons email i found the code from the link http://commons.apache.org/email/userguide.html.

Where can i write the code and how can i assign values for the fields in the class?

Kindly help me out.

Thanks,
kavi

No, the mail task doesnt allow to add attachment.
But it is very easy to write your own (or extends the existing) ActivityBehaviour to do that.

Hi ,

Implement a java-class that implements JavaDelegate, and use that class in your process:

serviceTask id="javaService"
             name="My Java Service Task"
             activiti:class="org.activiti.MyJavaDelegate" />

public class ToUppercase implements JavaDelegate {
 
  public void execute(DelegateExecution execution) throws Exception {
    String var = (String) execution.getVariable("input");
    var = var.toUpperCase();
    execution.setVariable("input", var);
  }
 
}

You can read all this is the userguide, examples are included as unit-tests… That should do to get you started

Hi ,

I have created a class for mail attachment and wrote the code in myname.java.
In service task i included
<serviceTask completionQuantity="1"  activiti:class="mailattachment" id="sid-1430FC68-FA04-41E0-9EDB-A9A0329F42A3" implementation="webService" isForCompensation="false" name="Email to applicant on status &quot;OnHold&quot;" startQuantity="1">….
But when i run my process when it comes to this service it says "05280002 Wrapped Exception (with status template): couldn't instantiate class mailattachment ".

When i searched in forum i found that i should include the file in as jar in "activiti\apps\apache-tomcat-6.0.32\webapps\activiti-rest\WEB-INF\lib" .
How to create jar file for .java file.?

Hi,

package org.apache.commons.mail does not exist
import org.apache.commons.mail.EmailException;

What am i missing?

Hi ,

I am not able to compile any of the java file present in

C:\activiti\workspace\activiti-engine-examples\src\main\java\org\activiti\examples\bpmn\servicetask

.

     It says import error. It seems the lib reference is missing.

How to include reference. Eg:import org.activiti.engine.delegate.Expression; says cannot find org.activiti.engine.delegate.

So how to compile this?

Thanks
kavi

Just add the Activiti jar to your classpath.

HI @frederikheremans,

-As suggested by you,I tried implementing the Business logic in my java service task via commons email.
-Created 1 attachment field in the bpmn20.xml file as:-  <activiti:formProperty id="attachment to be provided" expression="${attachment}" name="attachment" type="string" required="false"/>
-Next I tried to modify the source code via MailActivityBehavior class.

This is throwing me an error as(partially quoted) :

Please let me know the type for email attachment to be according to the error?
Grateful if you could provide your email id.

Thanks in advance!!

Hi,

It looks like you try to set a variable of type EmailAttachment in the process instance context, is that right?
You can't do that because EmailAttachment doesn't implement the Serializable interface. Therefore this error message.

Best regards,
