Remote procedure call supporting multiple versions

A remoting server comprising:

• a memory to store a version identifier of a server remote access application;
• a processing device, operatively coupled to the memory, the processing device to:
• receive an invocation request from a remoting client, the invocation request comprising a prefix comprising a client version identifier to indicate a version of a client remote access application of the remoting client, wherein the invocation request is formed by a client invoker instance on the remoting client, the client invoker instance being identified from an invoker registry on the remoting client using an invoker locator corresponding to the remoting server, the invoker locator comprising a uniform resource locator (URL);
• convert the invocation request from a wire data format to an object format with a data unmarshaller of the remoting server;
• generate a response to the remoting client with an invocation handler of the remoting server;
• associate a prefix with the response, the prefix comprising a server version identifier to indicate a version of a server remote access application of the remoting server;
• convert the response from an object format to a wire data format with a data marshaller of the remoting server for communication over a network to the remoting client;
• send the response comprising the server version identifier of the server remote access application to the remoting client;
• determine a compatible version between the client remote access application and the server remote access application in view of the client version identifier received from the client remote access application and the server version identifier of the server remote access application, wherein to determine the compatible version, the processing device to select a version for the server remote access application to support a plurality of client versions concurrently, each for a different client connection;
• and
• adjust the version of the server remote access application in response to determining the compatible version.

A non-transitory computer-accessible storage medium including data that, when accessed by a processing device, cause the processing device to:

• receive an invocation request from a remoting client, the invocation request comprising a prefix comprising a client version identifier to indicate a version of a client remote access application of the remoting client, wherein the invocation request is formed by a client invoker instance on the remoting client, the client invoker instance being identified from an invoker registry on the remoting client using an invoker locator corresponding to the remoting server, the invoker locator comprising a uniform resource locator (URL);
• convert the invocation request from a wire data format to an object format with a data unmarshaller of the remoting server;
• generate a response to the remoting client with an invocation handler of the remoting server;
• associate a prefix with the response, the prefix comprising a server version identifier to indicate a version of a server remote access application of the remoting server;
• convert the response from an object format to a wire data format with a data marshaller of the remoting server for communication over a network to the remoting client
• provide the response comprising the server version identifier of the server remote access application to the remoting client;
• determine, by the processing device of the server, a compatible version between the client remote access application and the server remote access application in view of the client version identifier received from the client remote access application and the server version identifier of the server remote access application, wherein to determine the compatible version, the processing device to select a version for the server remote access application to support a plurality of client versions concurrently, each for a different client connection;
• and
• adjust the version of the server remote access application in response to determining the compatible version.
