Seam mail : IncompatibleClassChangeError

greko.gregory.tanneau.gmail.com Mar 10, 2008 6:41 PM

Hi all !

I would like to have your opinion on my error.
I have a Seam 2.0.1 EAR running on jboss-4.2.1.GA, using Seam mail with attachement.

When I compile/deploy on Windows (using jdk1.5) evertything is ok.

When I compile/deploy on Unix (same jboss, jdk1.5 too), everything seems ok, except when i have an attached file in my email :

Here is the view :

<m:message xmlns="http://www.w3.org/1999/xhtml"
           xmlns:m="http://jboss.com/products/seam/mail"
           xmlns:ui="http://java.sun.com/jsf/facelets"
           xmlns:f="http://java.sun.com/jsf/core"
           xmlns:h="http://java.sun.com/jsf/html">

    <m:from name="do-not@reply.fr" address="do-not@reply.fr" />
    
    <m:to name="#{identity.username} &lt;#{emailSender.email}&gt;">#{emailSender.email}</m:to>
    
    <m:subject>The e-mail you requested (Pdf attached)</m:subject>
    
    <m:body type="html">
      <html>
       <body>
        <p><h:outputText value="Dear #{identity.username}" />,</p>
        <p>This example email demonstrates how <u>easy</u> it is to send an email!</p>
        <br />
        <p>Regards.</p>
       </body>
      </html>
    </m:body>
    
    <m:attachment fileName="pdf_users.pdf">
      <ui:include src="/test/pdf_test.xhtml" />
    </m:attachment>
    
</m:message>

Here is what I get, after compiling, recompiling, testing and testing again :

Even if I try to put a simple attachment (image, or even plain text), I have the same error.

If a remove the attachment, everything is ok ...

Could you help me, or give me an advice ?

Thanks !

Do you have som sort of version mismatch between the Javamail and Java Activation Framework jars (own version of one, picking other from AS or such)?

Hello Nickals,

I tried to pickup the activation.jar from AS (the one I used was different).

But the error is still the same...

I tried to deploy with another JBoss AS (same version), on another Unix server, and I have the same problem.

Any idea ?

Can you send a mail with attachments if you assemble it through the JavaMail API (and not through a template)?

Hello again,

I'm currently using activation.jar and mail.jar from seam 2.0.1.GA.
I deploy on JBoss AS 4.2.1.GA

Here is what I get, after trying to send an email with an attachment, directly via JavaMail API :

Caused by: java.lang.LinkageError: loader constraint violation: when resolving method "javax.mail.internet.MimeBodyPart.setDataHandler(Ljavax/activation/DataHandler;)V" the class loader (instance of org/jboss/m
x/loading/UnifiedClassLoader3) of the current class, com/cat/lc/nfp/sandbox/EmailSender, and the class loader (instance of org/jboss/mx/loading/UnifiedClassLoader3) for resolved class, javax/mail/internet/MimeB
odyPart, have different Class objects for the type javax/activation/DataHandler used in the signature

I wonder which version of which jar is correct ...

Fixed !

I found out that I had an activation.jar in my ear's lib directory.
I tried to replace it with the one from my JBoss AS : same error.
Then I tried to remove it : it works perfectly.

So there is no need of this jar in the ear (however that's what I read from seam doc : activation.jar, runtime, ear, Required for attachment support).

Anyway, thanks for your time.

The docs describe the generic dependencies required for a Seam runtime - not only for JBoss AS.
