Missing start boundary Exception when sending mess

问题:

I've found a number of possible matches to this problem but none that work for me.

I'm using Apache Camel to deliver a file as an email attachement. 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 - I'll check these later and add.

This is a simplified version of my camel routes:

<route id="uploadFileForm">
    <from uri="jetty:http://0.0.0.0:9095/premier"/>
    <to uri="velocity:form.html"/>
</route>
<route id="uploadFile">
    <from uri="jetty:http://0.0.0.0:9095/fup"/>
    <to uri="log:mail?showBody=true&amp;showHeaders=true"/>
    <to uri="smtp://localhost"/>
    <setHeader headerName="content-type"><constant>text/plain</constant></setHeader>
    <setBody><constant>Message Sent</constant></setBody>
</route>

This is what the log shows:

[4 - seda://mail-ws-audio-files] mail                           INFO  Exchange[ExchangePattern:InOut, Headers:{Connection=Keep-Alive, CamelHttpServletRequest=org.eclipse.jetty.servlets.MultiPartFilter$Wrapper@bb32c5, upfile=D:downloads!37SQFTS.pdf, CamelHttpPath=/fup, subject=BBC Premier League Update - Edition 1, CamelHttpQuery=null, CamelHttpServletResponse=HTTP/1.1 200

    please find attached the latest edition of our file. 

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?

I have tried your simplified camel route sample, it works well with mvn jetty:run.

In my Tomcat 7.0.27, Java 6, it actually works. The mail was sent correctly. The only difference is I don't use the:

mvn install

Instead using:

mvn package

Then copy the target/test-mail-0.0.1-SNAPSHOT.war to the Tomcat webapps folder, and start tomcat (bin/startup.sh or bin/startup.bat).

Hope this works for you as well.

My suggestion that you pick the same Tomcat version as I had and follow the same step.

Other source of problem you should:

1. Check is whether you have environment variable CATALINA_HOME or CATALINA_BASE unsuspectingly to you set to point to other Tomcat installation.
2. Also in the environment variable, check the content of your JRE_HOME or JAVA_HOME (when using JDK), and your CLASSPATH variable. You should set your classpath to $JAVA_HOME/jre/lib:$JAVA_HOME/jre/lib/ext:. or %JAVA_HOME%/jre/lib;%JAVA_HOME%/jre/lib/ext;. (the last dot is very important)
3. Substitute JAVA_HOME/lib with JRE_HOME if you are running on JRE only.
4. What version of JVM are you running. I am using Oracle JDK 6. Are you using OpenJDK/J9 or something else?

回答2:

I've got a working solution to my problem, but not an answer to my question. My original route set works every way I've tried it except in Tomcat and requires no java code (of my own).

I've taken a brute force approach and moved the jetty generated attachement to the body, and then later in the route, move it back to an attachment. It gets me to something I can deploy, but its a hack.

Still looking for a way to deploy my original route set in Tomcat 6.
