Self-signed java applet raise error "Permission denied" while send mail via SMTP

I have self-signed java applet. This applet should send email message every time, when raise unhandled exception. My applet crashed with exception in that moment, when I am trying to send mail. For sending email I usung Java Mail API (javax.mail).

Java console shows follow text:

javax.mail.MessagingException: Could not connect to SMTP host: host.ru, port: 25;
 nested exception is:
java.net.SocketException: Permission denied: connect

It's possible that you are executing your code from eclipse with java 1.6 version, and when you use this code as an applet java plug-in is executing on java 1.7?

If this is the case you can add this parameter to your applet call:

<PARAM name="java_arguments" value="-Djava.net.preferIPv4Stack=true">

If you are using deployJava.js:

<script src="https://www.java.com/js/deployJava.js"></script>
<script>
   var attributes = {...} ;
   var version = '1.7';
   var parameters = { java_arguments : '-Djava.net.preferIPv4Stack=true'...} ;
   deployJava.runApplet(attributes, parameters, version);
 </script>

Keep in mind that if you use java mail api the SMTP Server must be located on the same machine as the web server (http://www.oracle.com/technetwork/java/faq-135477.html#applets)

Hope this helps,
