Wrapping it up

When companies like Microsoft and Sun Microsystems release innovative products like Java and Win32, the computer industry benefits. I believe that the combination of these two technologies will usher in a new era of Windows software that is more robust than equivalent software written purely in C++. The ZIP application, introduced in this article, provides a bare glimpse of what is possible. I think this is exciting -- the potential is great. And who knows, maybe Sun and Microsoft will merge after all!

Resources
  • The zip archive contains all of the necessary C++/Java source and deployment files used by this article http://www.javaworld.com/jw-07-1998/java-win32/zip.zip
  • I've found the following resources beneficial when I'm writing applications that use the Java native Interface (JNI).
  • Essential JNI Java Native Interface, by Rob Gordon. PublisherPrentice Hall, Copyright1998. This book dives into JNI, and covers many techniques for calling C++ code with Java and calling Java with C++ code. One chapter focuses on the Invocation API and how to construct a C++ application which embeds the Java Virtual Machine -- in other words, how to create your own AppletViewer.exe program.
  • The JavaWorld article Use native methods to expand the Java environment provides an introductory look at the Java Native Interface http://www.javaworld.com/javaworld/jw-07-1997/jw-07-javadev.html
