Java Edition Introduction

About the Autodesk MapGuide Viewer, Java Edition

The Autodesk MapGuide Viewer, Java Edition works with Internet Explorer and Netscape Navigator, on Windows, MacOS^®, and Solaris^® systems. It exposes an API that is accessible from JScript, JavaScript, and Java. The API classes are defined in the com.autodesk.mgjava package, which is located in the mgjava.cab file (for Windows systems only) and the mgjava.jar file (for all platforms). All configurations expose the Autodesk MapGuide Viewer, Java Edition API to other Java code if it has been compiled to directly instantiate MGMapApplet or MGMapComponent. See "Accessing Maps" in the Autodesk MapGuide Developer's Guide for more information.

Depending on your application needs, Autodesk MapGuide Viewer, Java Edition applications may need certain Java files provided by Autodesk MapGuide. For more information about what files your application may need, go to Plug-In/Java Edition Downloadable Files.

The Autodesk MapGuide Viewer, Java Edition is almost identical to the Autodesk MapGuide Viewer Plug-In API with the following exceptions:

The Autodesk MapGuide Viewer Plug-In API resides in the mapguide package, located in the npmapv32.zip file in the Netscape Plugins folder. The Autodesk MapGuide Viewer, Java Edition API resides in the com.autodesk.mgjava package, which is located in the mgjava.cab file (for Windows systems only) and the mgjava.jar file (for all platforms).
Classes in the Autodesk MapGuide Viewer Plug-In API are Java interfaces in the Autodesk MapGuide Viewer, Java Edition API.
The Autodesk MapGuide Viewer, Java Edition has some cosmetic and functional differences from the other Autodesk MapGuide Viewers. For details about these differences, see "About the Java Edition" in the Autodesk MapGuide Viewer Help.
