Has anyone seen JavaMail not sending proper MimeMessages to an SMTP server, depending on how the JVM in started? At the end of the day, I can't send JavaMail SMTP messages with Subject: or From: fields, and it appears other headers are missing, only when running the app as a war.

The web project is built with Maven and I'm testing sending JavaMail using a browser and a simple mail.jsp to debug and see different behavior when launching the app with:

1) mvn jetty:run (mail sends fine, with proper Subject and From fields)

2) mvn jetty:run-war (mail sends fine, but missing Subject, From, and other fields)

I've meticulously run diff on the (verbose) Maven debug output (-X), and there are zero differences in the runtime dependencies between the two. I've also compared System properties, and they are identical. Something else is happening the jetty:run-war case that changes the way JavaMail behaves. What other stones need turning?

Curiously, I've tried a debugger in both situations and found that the javax.mail.internet.MimeMessage instance is getting created differently. The webapp is using Spring to send email picked off of an Apache ActiveMQ queue. When running the app as mvn jetty:run the MimeMessage.contentStream variable is used for message content. When running as mvn jetty:run-war, the MimeMessage.content variable is used for the message contents, and the content = ASCIIUtility.getBytes(is); call removes all of the header data from the parsed content. Since this seemed very odd, and debugging Spring/ActiveMQ is a deep dive, I created a simplified test without any of that infrastructure: just a JSP using mail-1.4.2.jar, yet the same headers are missing.

Also of note, these headers are missing when running the WAR file under Tomcat 5.5.27. Tomcat behaves just like Jetty when running the WAR, with the same missing headers.

With JavaMail debugging turned on, I clearly see different output.

GOOD CASE: In the jetty:run (non-WAR) the log output is:

BAD CASE: The log output when running as a WAR, with missing headers, is quite different:

Here's the actual mail.jsp that I'm testing war/non-war with.

<%@page import="java.util.*"%>
<%@page import="javax.mail.internet.*"%>
<%@page import="javax.mail.*"%>

<%
    InternetAddress from = new InternetAddress("[email protected]", "Webmaster");
    InternetAddress to = new InternetAddress("[email protected]", "Jason Thrasher");
    String subject = "non-Spring: Hello World";
    String content = "Hello World: message body here";

    final Properties props = new Properties();
    props.setProperty("mail.transport.protocol", "smtp");
    props.setProperty("mail.host", "mail.authsmtp.com");
    props.setProperty("mail.port", "465");
    props.setProperty("mail.username", "myusername");
    props.setProperty("mail.password", "secret");
    props.setProperty("mail.debug", "true");
    props.setProperty("mail.smtp.auth", "true");
    props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.setProperty("mail.smtp.socketFactory.fallback", "false");

    Session mailSession = Session.getDefaultInstance(props);

    Message message = new MimeMessage(mailSession);
    message.setFrom(from);
    message.setRecipient(Message.RecipientType.TO, to);
    message.setSubject(subject);
    message.setContent(content, "text/plain;charset=UTF-8");

    Transport trans = mailSession.getTransport();
    trans.connect(props.getProperty("mail.host"), Integer
            .parseInt(props.getProperty("mail.port")), props
            .getProperty("mail.username"), props
            .getProperty("mail.password"));
    trans.sendMessage(message, message
            .getRecipients(Message.RecipientType.TO));
    trans.close();
%>

email was sent

SOLUTION:

Yes, the problem was transitive dependencies of Apache CXF 2. I had to exclude geronimo-javamail_1.4_spec from the build, and just rely on javax's mail-1.4.jar.

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-frontend-jaxws</artifactId>
    <version>2.2.6</version>
    <exclusions>
        <exclusion>
            <groupId>org.apache.geronimo.specs</groupId>
            <artifactId>geronimo-javamail_1.4_spec</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Thanks for all of the answers.
