Weblogic jndi initialcontextfactory

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.

    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.

    Remember that a custom object can be bound to the JNDI tree only if its class implements the java.

    The clustered bindings from different servers are replicated across to all the servers, keeping them in sync. If network channels are configured, it is possible to set the cluster address on a per channel basis.

    WebLogic JNDI access from external clients

    This is not an efficient use of resources and may result in the incorrect user being returned by ctx. The following code snippet illustrates such use:.

    In addition to the standard Java interfaces for JNDI, WebLogic Server provides its own Establish an InitialContext with WebLogic Server.

    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.

    Creating a subcontext named wlsunleashed. To a client, each naming service is identical, regardless of which clustered server it's connected to—hence the concept of a single clusterwide JNDI tree. After the InitialContext has been used, the context isn't necessary any more. Oracle technology is changing and we strive to update our BC Oracle support information.

      To tag a binding as a non-replicated, set the value of the WLContext.

    2. Aram:

      The property java. AddToEnvironment can be used to change other properties after the creation of the context.

    3. Mesho:

      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. All you have to do is to configure these resources in the appropriate configuration descriptor.

    4. Brakus:

      A Java client that wants to access services of an object that's already been loaded into a WebLogic Server's JNDI tree would typically perform the following tasks:.

      This attribute defines the address to be used by clients to connect to a cluster.
