Duplicate resource names might cause problems
 Technote (FAQ)
 
Problem
If the administrative console is used to create two different resources and the same name and JNDI name are assigned to both of the resources, the error will be detected and reported but the Default Server will still start successfully. However, when an application program does a lookup using the duplicate JNDI name, it may get the wrong resource and try to use it, which could cause problems.

For example, suppose a user creates a JavaMail mail session with one set of properties (Mail Transport Host = transhost1.com, Mail Store Host = storehost1.com, and so on) and with a name of "Test MailSession" and a JNDI name of "mail/DefaultMailSession". Further suppose the user then creates a second JavaMail mail session with a different set of properties (Mail Transport Host = transhost25.com, Mail Store Host = storehost25.com, and so on) and with the same name and JNDI name as the first mail session. Error messages similar to the following will be reported by the administrative console when the duplicate resource is created and in the default_server_stdout.log file when the server is started:

CHKW3050E: Duplicated resource factory name Test MailSession. [MailSession_3] CHKW3051E: Duplicated resource factory JNDI name mail/DefaultMailSession.
[MailSession_3]

If the user runs an application affected by the duplicate name errors, transhost1.com and storehost1.com might be used when the user really wants to use transhost25.com and storehost25.com.
 
Solution
When you see a duplicate name message (either at resource creation time or server startup time), change the names of one of the resources to resolve the problem. You can then start the server and run your application.
