The Java EE and EJB specifications provide a core set of security services that application developers can integrate declaratively and programmatically These include: Authentication This is the process of validating the identity of a user who is trying to access a secured system When authenticating, the application server verifies that the user actually exists in the system and has provided the correct credentials, such as a password Authorization Once a user is authenticated in a system, he will want to interact with the application Authorization involves determining whether a user is allowed to execute a certain action Authorization can police a user s access to subsystems, data, and business objects, or it can monitor more general behavior Certain users, for example, may be allowed to update information, whereas others are allowed only to view the data For web applications, maybe only certain users are permitted to access certain URLs. convert excel to pdf c# itextsharp Steps to convert excel document to PDF program matically:

For EJB applications, the user can be authorized on a permethod basis.. A mirror of stripes is constructed, as shown in Figure 7-5, by first creating a RAID 0 set and then mirroring it. 4. Create a data source and add a connection string to the application configura tion file by running the Data Source Configuration Wizard. 5. Create event handlers for the button-click events. 1 5 9 13 Although a small programmatic API is available for interacting with Java EE security services, users rarely have to write any code to secure their applications, because setting up security is usually a static, declarative process. Only session beans can be secured in EJB. This chapter focuses on how to set up authentication and authorization for your session beans. 2 6 10 14 5 In a secure EJB application, authentication involves verifying that a user is who she says she is. When a remote client logs on to the EJB system, it is associated with a security identity for the duration of that session. Once a remote client application has been associated with a security identity, it is ready to use beans to accomplish some task. When a client invokes a method on a bean, the EJB server implicitly passes the client s identity with the method invocation. When the EJB container receives the method invocation, it checks the identity to ensure that the client is valid and is allowed to invoke the target method. Unfortunately (or fortunately, depending on your perspective), the EJB specification does not specify how authentication happens. Although it defines how security information is propagated from a client to the server, it does not specify how the client is supposed to obtain and associate identity and credentials with an EJB invocation. It also does not define how the application server stores and retrieves authentication convert excel to pdf c# free How to convert Excel to PDF using C# and VB.NET | WinForms - PDF
