I have a class that have a method that sends an email using javax.mail .I've compiled the code and it was working fine,then suddenly I started to get InvocationTargetException and I don't know what is causing it.
Here is my code :
import java.lang.reflect.InvocationTargetException;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
public class SendEmailClass {
private static String USER_NAME = "email@domain.com" ;
private static String PASSWORD = "Password";
private static String RECIPIENT = "email@domain.com";
private SendEmailClass () {
}
public static String getStr (String str) {
String from = USER_NAME;
String pass = PASSWORD;
String[] to = { RECIPIENT }; // list of recipient email addresses
String subject = "Test Email";
String body = "mail notification " + str ;
SendEmail(from, pass, to, subject, body);
return "test" + str ;
}
public static void SendEmail(String from, String pass, String[] to, String subject, String body) {
Properties props = System.getProperties();
String host = "Some IP Address";
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props);
MimeMessage message = new MimeMessage(session);
try {
message.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
// To get the array of addresses
for( int i = 0; i < to.length; i++ ) {
toAddress[i] = new InternetAddress(to[i]);
}
for( int i = 0; i < toAddress.length; i++) {
message.addRecipient(Message.RecipientType.TO, toAddress[i]);
}
message.setSubject(subject);
message.setText(body);
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
catch (AddressException ae) {
ae.printStackTrace();
}
catch (MessagingException me) {
me.printStackTrace();
}
}
}
When I invoke method "getStr" I get that exception ,I tried to handle it by putting catch block after at the end of "SendEmail" method , so the method becomes like this :
public static void SendEmail(String from, String pass, String[] to, String subject, String body) {
Properties props = System.getProperties();
String host = "40.101.62.34";
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
Session session = Session.getDefaultInstance(props);
MimeMessage message = new MimeMessage(session);
try {
message.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
// To get the array of addresses
for( int i = 0; i < to.length; i++ ) {
toAddress[i] = new InternetAddress(to[i]);
}
for( int i = 0; i < toAddress.length; i++) {
message.addRecipient(Message.RecipientType.TO, toAddress[i]);
}
message.setSubject(subject);
message.setText(body);
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
catch (AddressException ae) {
ae.printStackTrace();
}
catch (MessagingException me) {
me.printStackTrace();
}
catch (InvocationTargetException ex){
// handle exception
}
}
}
But then I get that : "Unreachable catch block for InvocationTargetException. This exception is never thrown from the try statement body"
How do I handles this and find what causing the exception? Please help .
