If the object of interest is bound in only one WebLogic Server, you must explicitly connect to the host WebLogic Server by setting the Context. To do so, pass the hashtable to the constructor for InitialContext. Perform the test again, but this time provide the command-line arguments along with the jndi. Properties such as these are identified by constants in the weblogic. Unless you choose the object not to be clustered, the binding is replicated across to the other servers. If the thread already has been associated with a WebLogic user, that security principal is used for all authorization checks when you subsequently access the JNDI tree. This approach is described later in this chapter in Section 4. Experiment with this example a little more by creating a jndi.
The WebLogic Server JNDI Service Provider Interface (SPI) provides an InitialContext implementation that allows remote Java clients to connect to WebLogic.
Using WebLogic’s JNDI WebLogic The Definitive Guide [Book]
To create a WebLogic context from a client, your code must minimally specify this as the initial context factory, and the URL of a WebLogic Server in the JNDI. receive the name of initial context factory in Weblogic Server. means you need to connect to the WebLogic Server jndi tree use the.
It's often useful to bind objects under subcontexts rather than under the root context. If you want to create InitialContext with these defaults, write the following code:.

However, while using only nonreplicated bindings, there will not be any naming conflicts; that is, two servers in the cluster can have different objects using the same name bound to their JNDI trees. The security context actually is associated with the thread running the code.
This section discusses the way an external client can be used to access the partition specific JNDI tree. The resulting Context is replicated so that it can fail over transparently to any WebLogic Server in the cluster.
In order to access WebLogic's JNDI tree, you need to establish a standard JNDI InitialContext representing the context root of the server's directory service.
The following Java class do WebLogic JNDI Lookup. It looks HR data source is not required. You can call the InitialContext without argument.
It is important to note that since this is not an RMI object, what you are binding into the JNDI tree and copying to the other WebLogic Servers is the object itself, not a stub that refers to a single instance of the object hosted on one of the WebLogic Servers. To accomplish this, you must perform the following procedure from within the client application:.
In the process of creating the context, user1 is associated with the thread and stored in the stack, that is, the current identity is set to user1. The InitialContext is built to the server where it's being requested. To tag a binding as a non-replicated, set the value of the WLContext. Destroying a Subcontext Just as subcontexts can be created, they can be destroyed.
Create a Context with username and credential called ctx1 for user1.
