I'm trying to run a jar file which sends a mail, using this command:

java -jar sendmail.jar

When I run the code from NetBeans everything works fine, but when I export to a jar file and run the jar file I get the following error:

Error Sending mailjavax.mail.MessagingException: Could not connect to SMTP host:
 smtp.<xxx>.com, port: 25;
  nested exception is:
        java.net.SocketException: Permission denied: connect

After I got the error I executed the code from NetBeans, and the mail was sent. Thus I don't have any issue with SMTP or connection.

I think that the jar file cannot locate the mail.jar. Please advise.

  • have you set proper classpath for your jar? – Abubakkar Sep 30 '13 at 06:37
  • If you created `.jar` from netbeans then you don't have to worry about supporting `mail.jar` file. It copy supported `.jar` file in lib folder next to your `.jar` file. – Vicky Thakor Sep 30 '13 at 06:39
  • If it runs fine in netbeans and not after build then it must be some kind of import not included into the jar file.. – JWqvist Sep 30 '13 at 06:41

  • How you are creating `.jar` file? – Vicky Thakor Sep 30 '13 at 06:48
  • @Abu - yes class path is properly set. – Shann Sep 30 '13 at 06:48
  • @VickyThakor - i just clean and build the project – Shann Sep 30 '13 at 06:49

  • Is there any chance that you are using different JVMs in NetBeans and in console to run jar? There are known issue with JDK7: http://stackoverflow.com/a/12902187/1430055 – Maxim Kolesnikov Sep 30 '13 at 06:54
  • @MaksimKolesnikov - i think this may be the issue. i see that the jvm on netbeans is 1.6. and on console is 1.7.how to change it to 1.7 on netbeans? – Shann Sep 30 '13 at 07:00
  • In Netbeans, right click on the project > properties > Libraries and choose a JDK 7 Java Platform. After that you'll see this error both in console and in NetBeans. To fix it you should explicitly define VM option `-Djava.net.preferIPv4Stack=true`. – Maxim Kolesnikov Sep 30 '13 at 07:08

Does your machine by any chance use ipv6? if it does, you can try to start your jar with the -Djava.net.preferIPV4Stack=true argument.

Be sure that the mail.jar is probably imported under the libs and your not just referenced it.

Be sure to put your mail.jar file into lib folder and also ensure that your lib folder and sendmail.jar files are present in same directory.
