4.05GA javamail problem

[bezdomny]

I'm using a base install of 4.05GA and I get the following exception when trying to use javamail. I'm using the default service bound to java:/Mail.

java.lang.NoClassDefFoundError: com/sun/mail/util/SharedByteArrayInputStream

I get the mail session fine, but when I try to create a MimeMessage object like so:
Message m = new MimeMessage(mailSession);

//this also fails:
MimeMessage m = new MimeMessage(mailSession);

I get the exception. Any ideas?

Thanks!!

Can you post the full stacktrace?

Hey Dimitris,
I would if I could, but as soon as the MimeMessage(mailSession) constructor is called and InvocationTargetException is thrown, then I see the java.lang.NoClassDefFoundError: com/sun/mail/util/SharedByteArrayInputStream

Here is my method:

public void sendMessage() {

try {
Session mailSession = null;

try {
Context ctx = new InitialContext();
Object objref = ctx.lookup("java:/Mail");
mailSession = (Session) PortableRemoteObject.narrow(objref, Session.class);
} catch (NamingException e) {

System.out.println(e);
e.printStackTrace();
}

MimeMessage msg = new MimeMessage(mailSession);

msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO, getAddresses());
msg.setText(mailMessage);

Transport.send(msg);

}
catch (MessagingException e) {
logger.log(Level.SEVERE, "messaging error: ", e);
}
}

Do you happen to have any duplicate version of mail.jar in your deployment?

[bezdomny]

Yep That was it. I'm using a third party jar that has some of the old sun/* classes included. When I removed that, my problem was solved. Thanks for the help.
