Hi, you could also take a look to this work by Jarl Lindrud (http://www.codeproject.com/KB/threads/Rcf_Ipc_For_Cpp.aspx), which is already based on boost (uses boost asio and boost serialization, but also provides custom alternatives for both), but it's not in the form of a boost library. In the past there has been some discussion about possible integration between this library and boost.interface. As a user, I'd highly appreciate to have one such library in boost (I'm currently using the library by Lindrud in several projects).

Hi All,

For the google summer of code 2008, I wish to build a Cross Platform Remote Method Invocation Framework for C++ using Boost.Asio, similar to Java's remote method invocation (RMI). I will provide some macro definitions to create the proxy code.

Please provide me your comments to adjust this idea to best suit the interests of boost community. I higly appreciate your suggestions.

A sample code that will use this framework wold look like,

account.h -------------- DECLARE_BEGIN_PROXY(account) DECLARE_METHOD_1(deposit, void, double); DECLARE_METHOD_0(get_balance, double); DECLARE_END;

class account { .......... ......... }

Server Code ----------------- account acc = new account("Foo", 250); Server s = new server(server::TCP, 19000); s.attach("Foo", acc); s.run();

Client Code ---------------- account_proxy acct = account_proxy::get_proxy("172.25.44.195", server::TCP, 19000, "Foo"); acct.deposit(100); double balance = acct.get_balance();

Thank You, Salinda _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost

What does cross-platform mean here if you can only make boostified C++ talk to boostified C++? Why invent the wheel all over again? Why not stick to some already existing solutions like Corba or such? Admittedly, the C++ language binding of Corba is just horrible nowadays and needs to be revisited. So in my eyes, it would be much more rewarding to work out a modern, boostified C++ language binding to an already existing RPC framework like Corba (or the like).

account.h -------------- DECLARE_BEGIN_PROXY(account) DECLARE_METHOD_1(deposit, void, double); DECLARE_METHOD_0(get_balance, double); DECLARE_END;

That would effectively go to an idl file. The advantage is that the same idl file would also be usable for C, Java, C# or whatever.

Server Code ----------------- account acc = new account("Foo", 250); Server s = new server(server::TCP, 19000); s.attach("Foo", acc); s.run();

Client Code ---------------- account_proxy acct = account_proxy::get_proxy("172.25.44.195", server::TCP, 19000, "Foo"); acct.deposit(100); double balance = acct.get_balance();

Something similar is needed in any of those frameworks and may be found as introductory example in many books. But how will client and server get to know each other? How will they be started? What about dynamic port numbers? What about authentication? Authorization? Lifetime management for proxy and/or server objects? If you just want some fun and do your own implementation, just go ahead and have fun. But if you want a broadly useful RPC mechanism for modern C++, get out some literature about existing frameworks, and think about why e.g. Corba is such a complex monster. You will probably observe that most pieces do indeed have their use cases. I assume that people behind Corba did probably invest much more brain power than most of us (at least me personally) would be willing to do.
