Posted on 1998-07-14

Platform : Windows NT 5.0
Language : VC++ 5.0, JDK1.1.6

I want to make a server with JKD1.1.6 and clients with VC++5.0.
Which data types do I have to use for socket comunication between VC++5.0 and JDK1.1.6?

There is no problem on each side.
I tested server  with JKD1.1.6 test client. And client with VC++5.0 test server.

Any idea?
If you have any sample code, please send it with your response.
Thanks in advance.

Any chance you can use CORBA for your project. There the conversion between language data formats will be handled by the ORB all you will need to do is to write interfaces using C++ and JAVA IDLs.

Hi, msmolyak!

But this time, I don't want to use CORBA.
I want to make it with pure java and VC++.

I'll wait your kindly response again.
Thanks again.

If you can't use higher-level network protocols like RPC, RMI or CORBA, you are limited to what TCP and UDP.

On the Windows side this means using winsock or another sockets library (such as the Cygnus Win32 Gnu libraries). On the Java side TCP and UDP are both supported in the java.net packet of course.

Once you're on this path, the data types are simply bytes. However these bytes can be cast into other native types on the C++ side, or produced via one of the factory methods on the Java side. While this is straightforward it's certainly low-level. You have to deal with marshalling your arguments for method calls by hand. None of it is difficult per se, but it is tedious.

A good reference on this topic is Stevens book called _Unix Network Programming_. When it was written sockets was not yet the standard on Windows that it is today, and so while the title refers to Unix it is generally applicable to all TCP/IP programming.
