Error with inbound mailserver: ClassCastException

binary-two — Thu, 07 Jan 2010 06:41:50 GMT

Hello Alfresco forum members!When I try to submit e-mails with attachments using the internal smtp-server, I get following error message (i.e. Java ClassCastException) on the server side:17:27:32,222 ERROR [org.alfresco.email.server.impl.subetha.SubethaEmailServer] javax.mail.internet.MimeMultipart

Hello Alfresco forum members,

has no one experienced the same issues? Any help would be highly appreciated. Has anyone the inbound e-mail server working for e-mails with attachments?

Kind regards,

Björn

I'm seeing the exact same error message. Reading the documentation ( http://java.sun.com/javaee/5/docs/api/javax/mail/internet/MimeMultipart.html )for javax.mail.internet.MimeMultipart, it looks like its parent is:

java.lang.Object
  extended by javax.mail.Multipart
      extended by javax.mail.internet.MimeMultipart
‍‍‍‍

AFAIK, you should be able to cast javax.mail.internet.MimeMultipart to javax.mail.Multipart since there is a parent/child relationship. The code causing the error seems to back this up:

            else if (messagePart.isMimeType(MIME_MULTIPART))
            {
                // if multipart, this method will be called recursively
                // for each of its parts
                Multipart mp = (Multipart) messagePart.getContent();
‍‍‍‍‍‍

Unless I'm reading something wrong. Maybe this is a bug in the version of Java?

I have:

# java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode)

Filed as a bug until I can figure out otherwise: https://issues.alfresco.com/jira/browse/ALFCOM-3813

Solution (on Red Hat Enterprise Linux 5):

mkdir -p WEB-INF/lib 
cp /usr/share/java/classpathx-mail/mail-1.3.1-providers.jar /usr/share/java/classpathx-mail/mail-1.3.1-api.jar WEB-INF/lib 
zip -d WEB-INF/lib/mail.jar 
zip -u alfresco.war WEB-INF/lib/* 
rm -rf WEB-INF/lib ‍‍‍‍‍

In other words, mail.jar is bad, mail-1.3.1-api.jar and mail-1.3.1-providers.jar are missing and need to be added.

This also fixes outgoing mail.
