NonStop Server for Java Programmer's Reference (NSJ 4.0+)

Java Print Service (JPS)
The Java Print Service is implemented into NonStop Server for Java 4. The Java Print Service allows you to
print on printers directly to NonStop systems and to network printers attached to local a area network (LAN)
or wide area network (WAN). For information on configuring network printers, see the Spooler FASTP
Network Print Processes Manual. For information on the Spooler subsystem, see the Spooler Utilities
Reference Manual.
The Java Print Service implemented into NonStop Server for Java 4 uses the headless version of the
javax.print API. All printing features and attributes in the JPS classes listed below function when the
NonStop Kernel spooler and printer support the API. However, the NonStop Kernel requirement for sending
text and postscript files to separate printers also applies when printing under JPs The JPs classes are:
javax.print●
javax.print.attribute●
javax.print.attribute.standard●
javax.print.event●
JavaBeans
JavaBeans are reusable software components that can run in both a design environment (inside a builder tool)
and a run-time environment.
The design environment is highly visual and requires that JavaBeans provide design information to the
programmer and allow the end user to customize its behavior and appearance.
In the run-time environment, JavaBeans might be visible, as in the case of a Graphical User Interface
(GUI), or invisible, as in the case of a data feed control.
Because of the nonvisual nature of the NonStop Kernel operating system, the NonStop Server for Java 4
supports only run-time execution of invisible JavaBeans. The NonStop Server for Java 4 does not support
design-time execution or run-time execution that requires a GUI operation. For this reason, in the NonStop
Server for Java 4, the Boolean expression java.beans.Beans isGuiAvailable returns the value
false.
The NonStop Server for Java 4 includes the JavaBeans Development Kit (BDK).
