Working With Proxies › Common Features of the Proxies

Common Features of the Proxies

Depending on your application, you need to use the most appropriate proxy. However, the .NET, Java, COM, and C Proxies share common features listed as follows:

• Allow access to CA Gen servers.
• Provide additional ways of building multi-tier applications.
• Provide a supporting interface for use with user-written code.
• Support multiple communication protocols. Each proxy uses a transport mechanism to communicate with a server execution environment.
• By default, each generated proxy provides a synchronous programming interface that can be accessed by user-written code. A CA Gen application developer can create proxies containing additional programming interface calls that support asynchronous flows to the target DPS. The communication protocol used must support asynchronous operation. Oracle Tuxedo does not support asynchronous communications.
• By default, each generated proxy provides a language specific definition to the data being exchanged, between the user-written client and server. A CA Gen application developer can create proxies that provide an XML interface. The XML interface can be used to provide a more flexible mechanism of exchanging data with the end user of a user-written application.

  Note: The XML interface is not available for C proxy.
