An external JNDI resource defines custom JNDI contexts and implements the javax.naming.spi.InitialContextFactory interface. There is no specific JNDI parent context for external JNDI resources, except for the standard java:comp/env/.
Create an external JNDI resource in one of these ways:
To create an external JNDI resource using the Administration Console, open the Resources component, open the JNDI component, and select External Resources. For details, see the Sun Java System Application Server Platform Edition 8.2 Administration Guide.
To create an external JNDI resource, use the asadmin create-jndi-resource command. For details, see the Sun Java System Application Server Platform Edition 8.2 Reference Manual.
