NMSV0307E: Naming error seen when using the embeddable EJB Container in J2SE program

Troubleshooting


Problem

When writing a J2SE program that performs java:comp lookups using the embeddable EJB container, you must remember that java:comp is only accessible within an EJB method. If you attempt to lookup a java:comp name directly from the main method, you will get an NMSV0307E error.

Symptom

NMSV0307E: A java: URL name was used, but Naming was not configured to handle java: URL names. The likely cause is a user in error attempting to specify a java: URL name in a non-J2EE client or server environment. Throwing ConfigurationException.
javax.naming.ConfigurationException: Name space accessor for the java: name space has not been set. Possible cause is that the user is specifying a java: URL name in a JNDI Context method call but is not running in a J2EE client or server environment.
