Enable client to connect to server by IP, not host name ------------------------------------------------------- Key: EJBTHREE-1935 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1935 Project: EJB 3.0 Issue Type: Feature Request Environment: JBoss 4.2.3 Reporter: Vasya Vasilchikov When a client lookups an EJB on the server for the first time, InitialContext is initialized and the client receives NamingServer_Stub. The stub contains server host name, not IP address, although the client called server with IP. If client machine fails to resolve the host name, subsequent calls for NamingServer_Stub fail. In Jboss 4.0.4GA the stub contained IP address. Please allow to configure IP-based stubs in Jboss 4.2.x also.
