SMTP server setting for Java Mail

[durnylka]

Hi,

I have a little knowledge of java and have no more ideas how to solve
my problem. Can you please have a look at it?

One of my applications is started via Java Web Start on a client PC.
This application has a possibility to send e-mails. Unfortunately
sending e-mails fails with the following log:

[...]
[10/26/06 13:15:01:413 CEST] 25cc04c4 SystemOut O * HOSTNAME =
linux.client.net

[10/26/06 13:15:02:098 CEST] 25cc04c4 WebGroup I SRVE0180I:
[ReportBrowser] [/ReportBrowser] [Servlet.LOG]: WARNING:
ReportJob.localExcecute(): Sending mail message failed for report (omc,
1019482) in REPORTER receivers: (e-mail address removed) Reason:

nested exception is:
javax.mail.MessagingException: Unknown SMTP host:
SMTPHOST.network.com;
nested exception is:
java.net.UnknownHostException: SMTPHOST.network.com

I can't find where SMTPHOST.network.com is set. Is it possible to
change this value? How to do it? I don't have source code of the
application in question but I hope that there is a way to set SMTP
server hostname without modifying the source code.

FYI: I edited the hostnames in the log.

Can you please help me?

Try this:

Properties properties = System.getProperties();
properties.put("mail.smtp.host", "yoursmtpserver");
Session mailSession = Session.getDefaultInstance(properties, null);
Message email = new MimeMessage(mailSession);
email.setFrom(..);
email.setRecipients(..)
email.setSubject(..);
email.setText(..);
Transport.send(email);

Check out javadocs on the above API usage for more information..

OK, thanks. But how to give properties to the application? Is it
possible to create a config file with the properties and force the
application to read it during the startup? I don't know it...:-/

Yes, it is possible. Some (easy) ways are :

-By having a properties file on the disk with name=value formatted
properties
-Using -D<name>=<value> option for the jvm when you run your program.
