A Java program using the toolbox can connect to OS/400 V4R2 or later. OS/400 V4R4 or later
is required when a Java program using the Toolbox is running on the iSeries.
The Toolbox requires JVM 1.1.6 or later and Swing 1.0.3 or later to balance content and
workload. Use a Web browser to administer and configure these servers.
The classes can be used by Java applets and applications to easily access iSeries data and
resources. They require no additional support over the inherent OS/400 support of Java
Virtual Machine and the iSeries Developer Kit for Java. The Toolbox for Java provides support
for similar functions to that provided by Client Access APIs. It uses the OS/400 host servers
(part of OS/400) to access the iSeries data and resources.
Each of these servers runs in a separate job on the iSeries server, communicating with a
Java client program using architected data streams on a socket connection. The socket
interfaces are hidden from the Java programmer by the Toolbox classes. JavaBeans are
provided for most public interfaces. They provide access to these iSeries resources:
• Database using JDBC driver. Supports the JDBC 2.0 specification.
• Database using Record-Level file access using the interface of the classes.
• Integrated file system.
• Programs: Any iSeries program can be called, parameters are passed to the iSeries
program, and data is returned to the Java program.
• Commands: Any iSeries batch command that is not interactive can be run.
• Data Queues: Access to both keyed and sequential data queues.
• Print: Using the print classes lists of spooled files, output queues printers, and other
print resources can be retrieved.
• User spaces: Create, read from, write to, and delete iSeries user spaces.
• Digital Certificates: Manage digital certificates stored on the system.
• Jobs: List active jobs on the iSeries and retrieve information about those jobs,
including the messages in the job log of a job.
• Message Queues: List, delete, and answer messages in a message queue. The ability
to send messages is also provided.
• Users: List users on the iSeries server and retrieve information about those users.
Additional classes provide the infrastructure needed to manage signon information, create
and maintain sockets connections to the iSeries services, and send and receive data. Data
description classes for numeric and character data are provided to allow the Java program to
describe the record format of a buffer of data with an object.
