J/Direct

J/Direct

J/Direct was a technology included in some versions of Microsoft's Java Virtual Machine, which allowed direct calls into the Windows API. J/Direct was specific of Microsoft's Virtual Machine, in replacement of the standard Java Native Interface (JNI).

A Java program which used J/Direct would not run on platforms other than Microsoft Windows.

The release of J/Direct (along with AFC and WFC), was part of an effort by Microsoft to gain leadership on the growing Java community [cite web

Since this destroyed one of the main advantages of Java, its cross-platform nature, J/Direct was often seen as an attempt by Microsoft to undermine Java's cross-platform capabilities, andan example of the tactic of Embrace, extend and extinguish.

After the drop by Microsoft of their specific Java Virtual Machine, and the switch to the .NET environment, J/Direct was no longer maintained.
