I'm not aware of that being supported within Java itself since it inherently breaks the JVM sandbox model - not usually something Java is looking to do.<br />
<br />
If you want access to a Win32 native Mutex, I'd suggest calling that API directly through JNI (Java Native Interface).<br />
<br />
That may sound a bit intimidating if you've not dealt with it before, but it's actually not much code to write, esp if you're familiar with C/C++.<br />

There's a tutorial here: <a href="http://www3.ntu.edu.sg/home/ehchua/programming/java/JavaNativeInterface.html" rel="ugc">http://www3.ntu.edu.sg/home/ehchua/programming/java/JavaNativeInterface.html</a><br />

Ended up using a native EXE to create mutexes.

Can anyone suggest a class to use or does anyone know if the Mutex class changed to something else?

Global Windows Mutex in Java

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Microsoft Development

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
