Hi, I am trying to implement a Java Class into my Service task but I am getting the following error in Camunda: “Cannot submit task form 943fe63b-7d3f-11ec-9632-70665515d97d: ENGINE-09008 Exception while instantiating class(…)”. It basically says that it can not load my Java class. Where is the error?
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
public class SendEmail {
final String senderEmail = "random@gmail.com"; //change email address
final String senderPassword = "random"; //change password
final String emailSMTPserver = "smtp.gmail.com";
final String emailServerPort = "465";
String receiverEmail = null;
static String emailSubject;
static String emailBody;
public SendEmail(String receiverEmail, String subject, String body) {
//receiver email
this.receiverEmail = receiverEmail;
//subject
this.emailSubject = subject;
//body
this.emailBody = body;
Properties props = new Properties();
props.put("mail.smtp.user",senderEmail);
props.put("mail.smtp.host", emailSMTPserver);
props.put("mail.smtp.port", emailServerPort);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.port", emailServerPort);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
SecurityManager security = System.getSecurityManager();
try {
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props, auth);
MimeMessage msg = new MimeMessage(session);
msg.setText(emailBody);
//System.out.println(emailBody);
msg.setSubject(emailSubject);
msg.setFrom(new InternetAddress(senderEmail));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(receiverEmail) );
Transport.send(msg);
System.out.println("Message sent!");
String className = this.getClass().getSimpleName();
System.out.println(className);
}
catch (Exception e) {
e.printStackTrace();
}
}
public class SMTPAuthenticator extends javax.mail.Authenticator{
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(senderEmail, senderPassword );
}
}
public class Tester {
public static void main( String [] args) {
SendEmail send = new SendEmail("testemail@gmail.com", "Test", "Camunda" ); //change receiver email
}
}
*here the print of the definitions made in the Service Task
