There are a few ways to connect into JNDI via the InitialContext() method.
You need to tell the JNDI program a few things so it knows how to connect,
where to connect, etc.
Since a Properties object extends the Hashtable, and the information that
you pass in tends to be
in the form of String's, you can use either a Properties object or a
Hashtable.
You often need to pass in the following:
java.naming.factory.initial = the jndi driver class (e.g.
weblogic.jndi.WLInitialContextFactory for BEA WebLogic)
java.naming.provider.url = where to find the jndi service (e.g.
t3://www.foo.com:7001)
java.naming.security.principal = often the username
java.naming.security.credentials = often the password
The strings above, are set as static final String's in the
javax.naming.Context class.
Context.INITIAL_CONTEXT_FACTORY = java.naming.factory.initial
Context.PROVIDER_URL = java.naming.provider.url
Context.SECURITY_PRINCIPAL = java.naming.security.principal
Context.SECURITY_CREDENTIALS = java.naming.security.credentials
So, in code, you can use either the strings, or the class constants.
If you do not want to hard code this information, you can place the string
information in a file named "jndi.properties"
that is located in your CLASSPATH, or $JAVA_HOME/lib/jndi.properties, and
just call new InitialContext() instead of new
InitialContext(hashtable_or_properties)
For example, in $JAVA_HOME/lib/jndi.properties:
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://www.foo.com:7001
java.naming.security.principal=system
java.naming.security.credentials=thepassword
Hope this helps,
