Using SendMailTransfomer with Cocoon 2.1.8

The SendMailTransformer needs the JavaMail and JavaBeans Activation Framework (JAF) API's from Sun to work. Add them to WEB-INF/lib. Remove geronimo-spec-javamail-1.3.1-rc5.jar and geronimo-spec-activation-1.0.2-rc4.jar from WEB-INF/lib.

Simple example

Add this to the transformers in your sitemap

<map:transformer name="sendmail" src="org.apache.cocoon.mail.transformation.SendMailTransformer"/>

Add this in a pipeline in your sitemap

<map:match pattern="mailme">
    <map:generate src="sendmail.xml"/>
    <map:transform type="sendmail"/>
    <map:serialize type="xml"/>

Example of sendmail.xml. The values in this document override those from the sitemap. You can remove them here if you have set them in the sitemap.

<?xml version="1.0" encoding="UTF-8"?>
<document xmlns:email="">
        <email:subject>My first mail</email:subject>
        <email:body>The body of the mail</email:body>

Advanced examples and parameters

See the APIdoc


It doesn't matter which SMTP-Host (or SMTP-Port) you fill in, you get the following error:

"Could not connect to SMTP host: localhost, port: 25 ( Connection refused: connect)"

if you have a mailserver running on your machine on port 25:

Exception sending mail java.lang.ClassCastException: java.lang.String


Cocoon uses geronimo-spec-javamail-1.3.1-rc5.jar and geronimo-spec-activation-1.0.2-rc4.jar (or the version that is included with your distribution) instead of Sun JavaMail and JAF. Remove geronimo-spec-javamail-1.3.1-rc5.jar and geronimo-spec-activation-1.0.2-rc4.jar from WEB-INF/lib and restart Cocoon.

If this still doesn't work remove geronimo-spec-javamail-1.3.1-rc5.jar from /lib/optional and remove it in lib/jars.xml (or comment it with <!-- -->). Copy src/blocks/mail/mocks from Cocoon 2.1.7 to the same directory in Cocoon 2.1.8 and rebuild Cocoon. Then add Sun JavaMail and Activation into WEB-INF/lib and remove geronimo-spec-activation-1.0.2-rc4.jar.
