Client stub reuse

[Tim Bartley]

Hi,

Are there any limitations on the reuse of client stub objects?

For example support I have Foo.wsdl and generate a client stub class Foo. Is it safe to do:

Foo stub;

while (1) {
        char* url = "" url from list of replicated servers>;
        if (tried all servers) {
                return error;
        }

        stub.setEndpoint(url);
        try {
                stub.invoke();
                return success;
        }
        catch (server unavailable) {
                continue;
        }
        catch (...) {
                return error;
        }
}

I expect that the stubs are re-entrant but not thread safe i.e. I expect to use exactly one, long lived, stub object per-thread (yes, I realize the code above doesn't quite achieve that).

Also, are transport connections e.g. in HTTP 1.1. transport, reused between method invocations? This particularly important for SSL where connection set up overhead can be very high. I assume they are (which is why I want to do the above) but thought I'd check.

Thanks,

Tim
