CORBA from .NET - (dis)recommended libraries?

I am working on a .NET-based server component that talks to a set of destinations (equity options exchanges, to be specific) using a variety of destination-specific protocols.

What is the best ORB for Java/C++ interoperation using CORBA?

I have a client-server application written in Java using CORBA for the communication. The ORB used is orbd, the one provided by the Java6 platform.

Cross-platform alternative to COM

I've been enamoured with component based programming (be it with COM, another system, or just using the paradigm in plain C++). It requires a bit of getting used to, if one is usually used to the "traditional" OOP model, but it's definetely worth it. It's made my code more maintainable and easier to extend. The project I'm currently wo...

Corba request timeout

I am working on a Corba client for some time. One problem that I run in is that I am not really able to define a timeout configuration. I am using a Mico C++ orb but it seems to be a global problem because I found noone who could describe if there is a Corba defined method to configure a request timeout. Does anyone know of such an int...

Corba sequence<octet> a lot slower than using a socket

I have a corba releated question. In my Java app I use typedef sequence Data; Now I played around with this Data vector. If I am right with the Corba specification sequence will either be converted to xs:base64Binary or xs:hexBinary. It should be an Opaque type and so it should not use any marshalling. I tried different idl styles: v...
