Problem with jetty & javamail running camel under tomcat

[julianc]

I'm using Apache Camel to deliver a file as an email attachment. It works perfectly using the following maven goals:

jetty:run

jetty:run-exploded

jetty:run-war

I'm using java 1.6. My deployment container is tomcat6. In tomcat6 and tomcat7 I get the following exception:

org.springframework.mail.MailSendException: Failed messages: javax.mail.MessagingException: Missing start boundary; message exception details (1) are:

Failed message 1:

javax.mail.MessagingException: Missing start boundary

at javax.mail.internet.MimeMultipart.parsebm(MimeMultipart.java:882)

The advice on the web suggests this is a class loader problem. Its either that the activation-1.1.jar or mail-1.4.4.jar files are not being found, or the mailcap file in mail-1.4.4.jar is not being found.

I've tried putting these jar files in tomcat/lib. I've tried copying the mailcap from the jar file into the META-INF directory of the exploded war. Neither of these make a difference.

Versions:

Windows: Apache Tomcat/7.0.5 JDK 1.6.0_27-b07 Apache Camel 2.8.0-fuse-00-08

Linux - the versions that come with ubuntu 10.04 LTS.

This is a simplified version of my camel routes:

     please find attached the latest edition of our file.

</pre>

A minimal example maven project is  here and the war is here. If you run the project in eclipse or with

    mvn jetty:run

and then use the form at http://localhost:9095/premier

You will get a "cannot contact server" exception. But if you deploy the war to tomcat you will get the missing start boundary exception. If you edit applicationContext.xml and replace the **** with valid values, it will actually send an email.

Any ideas?

There is a java mail 1.4.5 release. Maybe that works?

[julianc]

Thanks Claus, how would I change my pom to use that? Its picking the dependencies up from camel-mail with camel-version set to a fuse 2.8 version.

I've also shown that the most recent V7 tomcat fixes the problem, so its definately a class loader problem and jetty contains its own implementations of some of the java mail mime interfaces.

You can add a dependency on the javax mail 1.4.5 in your pom.xml, then that should shadow the transitive dependency from camel-mail.
