To view the Java Platform Manager, select Tools > Java Platforms. Alternatively, right-click on a project, choose Properties from the context menu, select Platform, and select the Manage Emulators button.
The Java Platform Manager is a tool for managing different versions of the Java Development Kit (JDK) and customizing Java platforms that your applications depend on. You can add source files and Javadoc™ documents to the existing platforms. For Java ME purposes, the platforms are emulators or SDK platforms for mobile devices.
The Java ME Platform SDK pre‐registers J2ME™ (CLDC and MIDP) and Java™ SE (the JDK serves as the default platform).
To view the Java Platform Manager, select Tools > Java Platforms. The Java ME platform supports CLDC projects. This platform also serves to run JavaFX projects.
Devices. View all the CLDC devices (including JavaFX devices) that the Device Manager has discovered. Click Refresh to reconfigure the platform and refresh the list.
Sources. Add JAR files or source files to the Sources tab to register source code.
Javadoc. Add Javadoc documentation to support any new classes or sources files you have added.
Tools & Extensions. View the tools and extensions for this platform.
