Troubleshooting: Naming service

The name service in a J2EE service which publishes and provides access to resources such as connection pools. If you have problems in accessing a resource which otherwise appears to be active, the naming service might be involved. Use these resources to determine the cause of the problem:

• Check the log files of the server for errors. Messages starting with NMSV are related to the naming service. For information on the logs files and where they are located, see WebSphere Application Server - Express log files.

• With the application server running, use the dumpNameSpace script to view the resources bound in to the name space for the application server. If the object a client needs to access does not appear in the name space, use the administrative console to verify that:

  • The server hosting the target resource is started.

  • The Web module hosting the target resource is running.

  • The JNDI name of the target resource is correct and up-to-date.

• If you see an exception that appears to be CORBA related, where CORBA appears as part of the exception name, look for a naming-services-specific CORBA minor code, in the exception stack for information on the cause of the problem.

• Read the release notes. See WebSphere Application Server - Express Release Notes for more information.
