Java Programming

Hello Everybody,

I have written a code in java for sending mail. Following is the
code:


public static void sendMail( String recipients[ ], String subject,
String message , String from) throws MessagingException
{
boolean debug = false;
//Set the host smtp address
Properties props = new Properties();
props.put("mail.smtp.host", "192.168.1.12");
// create some properties and get the default Session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
// create a message
Message msg = new MimeMessage(session);
// set the from and to address
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new
InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++)
{
addressTo[i] = new InternetAddress(recipients);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
System.out.println("To Address Set");
msg.addHeader("MyHeaderName", "myHeaderValue");
// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
System.out.println("Sub and content type set");
Transport.send(msg);
}
when I run this as a seperate code it works fine. But when I
integrate it into my application Apache server gives me following exception :
