---------------------------------------
Summary: Error while sending email because of javax.activation
Key: KARAF-5989
URL: https://issues.apache.org/jira/browse/KARAF-5989
Project: Karaf
Issue Type: Bug
Components: karaf
Affects Versions: 4.2.1
Reporter: Nicolas Dutertry
It is not possible to send email in Karaf 4.2 with javax.mail API. When an
email is sent, this exception is raised:
{code:java}
javax.mail.MessagingException: IOException while sending message;
nested exception is:
javax.activation.UnsupportedDataTypeException: no object DCH for MIME type
multipart/mixed;{code}
I’ve found that it is because the Activation Framework (javax.activation) is
not OSGI compliant. In the previous Karaf version (4.1) a servicemix
implementation of the Activation Framework was included but it is not the case
anymore.
The solution to have a working Activation Framework is to remove
javax.activation references in jre.properties and to install the bundle
org.apache.servicemix.specs/org.apache.servicemix.specs.activation-api-1.1/2.9.0.
For the future Karaf 4.2.2 can you please:
* Remove javax.activation from jre.properties
* Remove activation-1.1.1.jar from directory lib/boot
* Let the user install
org.apache.servicemix.specs/org.apache.servicemix.specs.activation-api-1.1/2.9.0
if needed
