Did this by ourselves.. I've been getting so many emails abt this.. so here's the code after 5 years

public void send(String uniqueId, Date reviewDateTime) throws Exception

{

          String from = "123@456.com";

          String to = "456@456.com";

                   // Define message

                   message.setFrom(new InternetAddress(from));

                   message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to, false));

I tried many blogs but none of them could solve my problem. Though stand alone java programs were sending the meeting invites, but on trying to send from JBOSS webservice, they were throwing exceptions and were failing.
Finally the code that worked for me was
