Question

Hi,
I enable JCOM in WLS 8.1.2 and once awhile I would see the following error message

Hello,
In general, JNDI clients should assume the correct environment is already configured so there is no need to explicitly set property values and pass them to the InitialContext constructor. However, a JNDI client may need to access a name space other than the one identified in its environment. In this case, it is necessary to explicitly set the java.naming.provider.url (provider URL) property used by the InitialContext constructor. A provider URL contains bootstrap server information that the initial context factory can use to obtain an initial context. Any property values passed in directly to the InitialContext constructor take precedence over settings of those same properties found elsewhere in the environment.
Context.PROVIDER_URL— specifies the URL of the WebLogic Server that provides the name service. The default is t3://localhost:7001. So that you are getting the following result:
ProviderURL=t3://localhost:7001
