Accessing Microsoft Windows Media Server from Java

 Java/J2EE COM Interoperability Products Page

This example demonstrates how to access Microsoft Windows Media Server from Java. J-Integra® for COM is a Java interoperability component that bridges Java and Microsoft Windows Media Server. It provides bi-directional access of Java objects and COM components. 

// This example shows a pure Java client using the J-Integra® pure Java-COM 
// bridge to talk to the Windows Media Server COM components to display 
// events when clients access media files.  You can run this program on any 
// machine that supports a standard JVM. 
// 
// For information on J-Integra® and to download an evaluation copy please 
// see http://j-integra.intrinsyc.com/ 
// 
// Create a file called WindowsMediaServerExample.java containing this 
// Java code. 
// 
// Create a subdirectory called 'windowsmedia' under the directory containing 
// this Java program, then generate the pure Java proxy files used by 
// this program to access the Windows Media Server COM components by running 
// the 'com2java' tool from the J-Integra® 'bin' directory. Specify 
// "\Program Files\Windows Media Components\Server\nsunimgr.ocx" 
// as the type library and "windowsmedia" as the package name, and the 
// windowsmedia subdirectory you created above, as the output directory. 
// 
// Compile and run the program with the J-Integra® runtime jintegra.jar in your  
// CLASSPATH. Start a client running from your browser, by selecting a URL such 
// as "mms://localhost/sample.asf" 
// 
// Watch the events arrive in the java client.
