Using ejb-jar.xml for @Singleton bean ------------------------------------- Key: JBMETA-329 URL: https://issues.jboss.org/browse/JBMETA-329 Project: JBoss Metadata Issue Type: Bug Security Level: Public(Everyone can see) Components: ejb Environment: JBoss AS 6.0.0.Final Reporter: Benoit Heinrich Assignee: jaikiran pai Attachments: startup-example.zip Hi all, After talking on the forum about a problem with @Singleton and the use of ejb-jar.xml I've been instructed to open a bug report. An example project is available on the jboss forum post, and can be used to reproduce the problem here. Here is the stacktrace thrown by jboss when deploying the attached sample project: {code} 12:48:35,699 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Real:
