Chapter 26. Using Java with Other Languages
Java has several methods of running programs
written in other languages. You can invoke a compiled program or
executable script using
, as I’ll describe in
Section 26.2. Or you can drop down to C level with
Java’s "native code” mechanism, and call
compiled functions written in
C/C++. From there, you can call to functions
written in just about any language. Not to mention that you can
contact programs written in any language over a
socket (see Chapter 15), with HTTP services (see Chapter 17), or with Java clients in RMI or CORBA clients
in a variety of languages (see Chapter 22).
There is an element of system dependency here, of course. You can only run MS-Windows applications under MS-Windows, and Unix applications under Unix. So some of the recipes in this chapter aren’t portable, though in a few cases I try to make them at least run on MS-Windows or Unix.
