To view the Java Platform Manager, select Tools > Java Platforms. The J2SE platform supports the Java ME Platform SDK. The CDC platform supports the CDC Stack, which also supports the BD-J Stack. In the standard Java ME Platform SDK installation the J2SE and CDC platforms have the same options:
Classes. View the platform’s classpaths. Add a JAR or folder containing additional classes, moving the classes up and down in the list determines their place in the classpath.
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.
