Example Overview

Example name : AssignOperationToView.java
Location : <Web NMS Home>/examples/Security/authorization directory

This example explains how to use the method "assignOperationToView()" and how a program will associate an operation to the already existing view. When the operation name and the view name are given as command line arguments, the respective operation will get added into the appropriate view.

The interface used in this example is AuthorizationAdmin

Method used in this example is :

assignOperationToView(java.lang.String operationName, java.lang.String authorizedViewName)

This method is used to associate an operation with an authorizedView.

Parameters: operationName - the name of the operation that is to be associated with the AuthorizedView.
authorizedViewName - the name of the AuthorizedView to which the operation is to be associated.
Throws: java.rmi.RemoteException - In case of RMI.
AuthorizationException - In case of null parameter, any exception or error during database operation.

After getting the handle of NmsAuthAdminAPI through an RMI lookup, the example assigns the specified operation to the respective view using the assingOperationToView() method.

Note : The source code will have comment statements in it which will explain to you the different segments of the program.

Integration with Web NMS

The steps given below will help you in integrating this example with Web NMS. If any of the steps given below are not followed properly, then the example might not function in a desired manner.

Set the <Web NMS Home>/classes directory to classpath
Compile the AssignOperationToView.java source file [ javac -d <Web NMS Home>/classes AssignOperationToView.java ]
Ensure that the class file is placed in the <Web NMS Home>/classes directory after compilation, in line with the package name specified in the program
Now start the Web NMS Server and wait till it successfully starts up
Execute the program, giving a operation name and view name as arguments (Ideally, the view must exist !) as given below :

java com.adventnet.nms.example.security.authorization.AssignOperationToView <operation name> <view name>

Sample Output

On giving an operation name and view name as arguments to this example program, the output of the program printed in your console, will be : "Assigned <operation name> to <view name>".

De-referencing

After you have tried this example, to remove its association with Web NMS, you must remove the class file AssignOperationToView.class from <Web NMS Home>/classes/com/adventnet/nms/example/security/authorization directory.
