Hey all...
We've been playing with using Java/HotJava applets to connect to an
internal data server and return info to the user. Unfortunately, our
server expects us to send a discrete packet of data across the net and then
wait for a response.
In C code, we simply have a structure, which we cast to a (char *) buffer and
write() into the socket.
We'd love to be able to do this in Java, but you can't cast a class to a
bytestream. We end up having to write each piece of the (large) struct
separately. This gets rather tiring for a struct with 15 elements!
Any suggestions? We've thought about implementing a write() method or
something, which knew how to write the struct to a stream, but it seems
redundant to do this for each structure.
I'm hoping I missed something realy simple in the java toolkit :)
Suggestions?
