Exclude the javax.mail jar from the kie-server war -------------------------------------------------- Key: DROOLS-1138 URL: https://issues.jboss.org/browse/DROOLS-1138 Project: Drools Issue Type: Bug Components: kie server Affects Versions: 6.3.0.Final, 6.4.0.Final, 7.0.0.Final Reporter: Marco Rietveld Assignee: Maciej Swiderski As far as I can tell, the `javax.mail` specification is part of the JEE 6 (and higher) specifications. However, we do *not! exclude the `javax.mail:mail` jar from the `kie-server` wars: See https://github.com/droolsjbpm/droolsjbpm-integration/blob/6.3.x/kie-serve... (`javax.mail:mail` is being included via the `jbpm-human-task-core` jar, which the `kie-server-services-jbpm` jar depends on.) Community users have reported running into classpath problems, which seem to be due to the inclusion of the `javax.mail:mail` jar In the JSR-316 (JEE 6 Specification) PDF, I found the following: {quote} EE.2.7.10JavaMail™ Many Internet applications require the ability to send email notifications, so the Java EE platform includes the JavaMail API along with a JavaMail service provider that allows an application component to send Internet mail. The JavaMail API has two parts: an application-level interface used by the application components to send mail, and a service provider interface used at the Java EE SPI level." {quote}
