2. This line makes all of the IBM Toolbox for Java classes in the vaccess package available to this program. The classes in the vaccess package have the common prefix com.ibm.as400.vaccess. By using an import statement, the program calls the name instead of the package plus name. For example, you can reference the AS400ExplorerPane class by using AS400ExplorerPane, not com.ibm.as400.AS400ExplorerPane.
