CLASSPATH is used to find classes if a class name is given instead of the filename. The --classpath option can be used to override this.

JAVA_HOME is used to find the default bootstrap classpath. The default bootstrap classes are assumed to be in JAVA_HOME/jre/lib/rt.jar. The --bootclasspath option can be used to override this.

To see what packages a class uses:

jclassinfo --packages /usr/share/java/MyClass.class

To see what packages the classes in myproject folder use:

jclassinfo --packages myproject/*.class
