The Toolbox provides a set of Graphical Access classes. These classes use the access
classes described previously to retrieve data and then present the data to the user. The
classes use Java's Swing 1.0 (JFC 1.1) framework. Graphical APIs are available to access
various iSeries resources, such as the database, Integrated File System, command call, and
data queues. The iSeries data is then displayed in various pane formats.
In addition, the iSeries Toolbox for Java provides:
• Easy access to additional iSeries resources, to work better in a three-tier environment,
and to make it easier to write servlets and write GUI applications with improvements to
the GUI builder tool.
• Additional Java APIs for accessing iSeries resources. APIs are added to call iSeries
service programs, call iSeries Java programs, interact with the iSeries FTP server, and
work with profile tokens.
• Ability to run many Toolbox classes with a proxy server running on a middle tier.The
Toolbox separates interface classes from implementation classes. These two parts can
be run in the same JVM (traditional two-tier model) or can be run on different machines
(three-tier model). By running in a three-tier model, the Toolbox package on the end
tier is smaller. In an applet environment, this makes the download faster, and a thinner
client can be used on the end tier. Since much of the processing is done on the middle
tier, the Toolbox uses less resources on the end tier.
• Servlet/HTTP components new to the Toolbox help developers write applications for a
Web environment. As in the other Toolbox components, these are not complete
applications, but are building blocks for application developers. Two sets of
components are provided. HTML classes provide a set of generic HTML components.
Servlet classes provide components that use the Toolbox access classes to retrieve
data and then convert the results to an HTML table or form.
• Enhanced GUI Builder tool of the Graphical Toolbox with an improved, easier to use
interface and additional editing capabilities. Some of the highlights of the new V5R1
enhancements include support to generate Java source for event handlers and the
capability for editing panes in other resources. Runtime and tools support are
enhanced to include context menus, menu bars, and toolbars. Panels are resizable, so
when the end user resizes a panel, the controls on that panel can also resize to show
more data. Support for handicapped accessibility, including user-setable fonts and
colors, and fully-functional keyboard navigation has been added.
• Support for Toolbox to run on a Linux workstation, run in Java 2, and implement GUI
components using Swing 1.1. The Toolbox connects to iSeries servers running OS/400
V4R2 or later.
• The Toolbox contains a spooled file viewer class. This GUI class shows print output.
