Extension-List MANIFEST attribute not honored during deployment of an EAR ------------------------------------------------------------------------- Key: JBAS-3131 URL: https://issues.jboss.org/browse/JBAS-3131 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Deployers Affects Versions: JBossAS-4.0.3 SP1 Environment: Windows XP SP2, JDK 1.5.0_06 Reporter: Alexander Sack Assignee: Jason Greene Fix For: 7.0.0.Beta1 If a JAR within an EAR specifies an Extension-List MANIFEST attribute, the EAR deployer does not honor it. I have a library, my.jar, that gets deployed that specifies an Extension-Name and Implementation-Version. If any of my jars within an EAR references this library, JBoss ignores the Extension-List attribute. The use of the Extension-List MANIFEST attribute is part of the core J2EE 1.4 spec and the EAR deployment should fail if the Extension-List library is not found (or if it is found and the <name>-Implementatino-Version does not meet the minimal requirements.
