Of course, you could pass the security credentials of a valid WebLogic user if you need to establish and use the context under a particular security scope. Right-click a node to view the policy for that node. As the policies are inherited, by applying a policy to the root node you will effectively be applying it to all nodes of the tree.
By applying such a policy, you are creating an authorization requirement on the actual lookup in the JNDI tree. You also can create authorization policies that apply to the objects bound in the JNDI tree itself. So, for instance, you can create a policy that restricts the lookup of a connection pool, and another that restricts the use of the connection pool. The default policy on the root of the JNDI tree grants access to the anonymous user in fact, to the group Everyone. Thus, if you do not specify the credentials of a WebLogic user when establishing an initial context, the anonymous user is automatically used to verify access control to the JNDI tree.
So, by default, you do have the necessary authorization to access the JNDI tree. 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.
Hence, if a security policy has been defined on a specific branch of the JNDI tree, you need to ensure that a valid principal is associated with the thread, and that it has sufficient privileges to access the branch. There are two ways in which you can establish an identity under which the JNDI tree ought to be accessed:.
When you create a JNDI context in this way, the security scope is valid for the lifetime of the context. It is terminated when you invoke the close method on the Context object. The security context actually is associated with the thread running the code. This has important implications. Establishing a new context will replace any previous security context associated with the thread. Thus, you should not try to establish a nested context using differing security principals.
In that case, all code will run using the most recently created context. After clients finish working with a Context, the client close the Context in order to release resources and avoid memory leaks. If you attempt to close a context that was never instantiated because of an error, the Java client application throws an exception. Marketing Advertising Analytics Email.

To accomplish this, the client application code must perform the following procedure: Set up JNDI environment properties for the InitialContext.
Use the named object to get a reference for the remote object and invoke operations on the remote object. You set these properties either by using: a hashtable. UserInfo interface with the Context. WLInitialContextFactory" ; ht. Environment ; environment. You can use the same properties on either a client or a server.
If you define the properties: on a server-side object, a local Context is used. For: Glassfish. Due to security isolation features but also due to direct access requirements to a single partition, a number of tasks need to be looked at. This chapter discussed a number of the most common connectivity and administrative challenges that came along with the new partition concept.
