Deploying exploded RAR with exploded JAR fails with CNFE -------------------------------------------------------- Key: WFLY-2892 URL: https://issues.jboss.org/browse/WFLY-2892 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: JCA Affects Versions: 8.0.0.CR1 Reporter: Darryl Miles Assignee: Stefano Maestri Priority: Optional This is the default method of deployment for JBoss AS Connector when using Eclipse and JBoss Tools. The resulting file layout is like: deployments/com.domain.rarproject.rar/com.domain.rarimpl.jar/com/domain/MyClassFile.class When the RAR is built into a JAR file, that contains the com.domain.rarimpl.jar inside deployment is sucessfull. The RAR deployer should allow the exploded layout where the "com.domain.rarimpl.jar" is of type directory (not file). Or JBoss AS Tooling should be fixed to understand the limitation of the AS RAR deployer during development of RAR/JCA driver. Other kinds of deployments allow exploded format via JBoss VFS.
