AS/400e Advanced Technology
state-of-the-art performance and support. AS/400e single-level-store technology permits
Java objects to be stored in their object form without the performance and maintenance
overhead of two-level-store operating systems.
Java Deployment Tools provided in V4R4 are aimed at simplifying the deployment,
management, and tuning of Java applications on AS/400e. IBM has tested InstallShield's
Java Edition product. InstallShield allows Java application developers to create packages that
will install natively on the AS/400e. It is the common method used to package and install
applications on other platforms, such as Windows NT. InstallShield on AS/400e makes it
easier to port applications to AS/400e that are currently targeted for other platforms. A
number of Qshell enhancements and utilities are provided to support zip or unzip of Java
packages. To aid in performance analysis and tuning of Java applications on AS/400e,
support is provided to convert data collected by Performance Explorer into standard formats
used by popular Java performance analysis tools such as Javation and Hyperprof.
The AS/400 Toolbox for Java is available. Java applets and applications that access AS/400e
programs and data from client workstations (or a Java-enabled server) can be written using
the AS/400 Toolbox for Java. Java classes on the client can be used to access existing
AS/400e applications and data using low-level APIs. The classes provide easy entry into Java
development while leveraging what already exists on the AS/400e today. A socket is used to
connect to OS/400 servers that provide access to AS/400 resources including:
• Remote commands
• Distributed program calls
• Data queues
• Data areas
• System values
• Integrated file system data (extended in V4R4)
• Print
• Record-level access
• Database access using a JDBC on the client
• User spaces
• Digital certificates
• Jobs
• Message queues
• Message files
• Users
• Object authority
• System status
The AS/400 Toolbox for Java provides a set of GUI classes as well. These classes use the
access classes discussed earlier to retrieve data for the user. The classes use Java's Swing
1.0.03 framework. When invoked, graphical APIs can display AS/400e data in the following
formats:
