How to send data streams?

[DennyOR]

I would like to efficiently send long streams of numerical data (byte or
integer arrays) back and forth between a local application and a java
servlet application. I assume the java APIs provide an easy way to do this.
What is it?

Thanks,
Denny

Depends on whyt you mean with "easy" and what your local application
uses. The standard way would be via a socket communication, but under
Unix, a named pipe would be a simpler alternative.

As for the actual data formatting, java.io.DataInputStream and
java.io.DataOutputStream (possible on top of BufferedIn/OutputStream)
should do fine, though you'll have to make up a communications protocol
to delimit the data and specify its type. Or is the "locap app" also
in Java? Then you can use ObjectIn/OutputStream.
