Hi, I am getting an exception - java.net.SocketException: Software caused connection abort: JVM_recv in socket input stream read I get this error for the line as follows: SmtpClient client = new SmtpClient(mailServer); The constructor takes the ip of the smtp server. import sun.net.smtp.SmtpClient; I have never used the sun.net.smtp.SmtpClient before. Where can I find a documentation or Api for knowing it better as I am debugging the code written by someone else. How do I get the error above? Thank You..
