Hi @all,
I try to use SMTPAppender for logging errors to respective users via E-Mail
in OSGi.
My configuration is:
OS: Ubuntu Linux 10.04.03 LTS
Application Environment: Glassfish 3.1.1 using Apache Felix
Logback: tried logback classic Version 0.29 and current Version 1.0 leading
to same results
Glassfish has following bundles
g! lb mail
START LEVEL 10
ID|State |Level|Name
227|Resolved | 1|JavaMail API (1.4.4)
I write following BundleActivator (I switch the real addresses with stubs),
sending an email via SMTPAppender and Java Mail from scratch.
package de.sgbs.log;
import java.util.logging.Level;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.Marker;
import org.slf4j.MarkerFactory;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.core.joran.spi.JoranException;
public class Activator implements BundleActivator {
private final static Logger logger =
LoggerFactory.getLogger(Activator.class);
@Override
public void start(BundleContext context) throws Exception {
try {
LoggerContext lc = (LoggerContext)
LoggerFactory.getILoggerFactory();
JoranConfigurator configurator = new JoranConfigurator();
configurator.setContext(lc);
lc.reset();
lc.putProperty("application-name",
Activator.class.getSimpleName());
configurator.doConfigure("logback.xml");
Marker notifyAdmin = MarkerFactory.getMarker("NOTIFY_ADMIN");
logger.error(notifyAdmin,
"This is a serious an error requiring the admin's attention",
new Exception("Just testing"));
} catch (JoranException ex) {
java.util.logging.Logger.getLogger(Activator.class.getName()).log(Level.SEVERE,
null, ex);
}
sendEMail();
}
private void sendEMail() throws MessagingException {
java.util.Properties props = new java.util.Properties();
props.put("mail.smtp.host", "smtp");
props.put("mail.smtp.port", "25");
Session session = Session.getDefaultInstance(props, null);
// Construct the message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("me at gmail.com"));
msg.setRecipient(Message.RecipientType.TO, new
InternetAddress("foo at bar.com"));
msg.setSubject("Test");
msg.setText("Hello user, you got an error:");
// Send the message
Transport.send(msg);
}
@Override
public void stop(BundleContext context) {
logger.info("Goodbye Community!");
}
}
My logback.xml
NOTIFY_ADMIN
TRANSACTION_FAILURE
smtp
foo at bar.com
me at gmail.com
TESTING: %logger{20} - %m
%date %-5level %logger{35} - %message%n
Sending from scratch works. SMTPAppender raises an error. This error is
given on the osgi console:

First I thought MIME type multipart/mixed is the cause. I checked my SMTP
Server Settings, sending email is ok. I tried googlemail. It's working too.
I found another https://bugs.eclipse.org/bugs/show_bug.cgi?id=322398
resource with the same error message. Could it be an classloader problem?
Could someone help me to pinpoint the problem?
Thanks in advance.
