applications for AS/400 system. The AS/400 Developer Kit for Java allows you to create and
run Java programs on the AS/400 system. The AS/400 Developer Kit for Java is a compatible
implementation of the Sun Microsystems, Inc. Java Technology. Unique aspects of the
AS/400 Developer Kit for Java design include:
• The integration of critical Java Virtual Machine components below the Technology
Independent Machine Interface (TIMI)
• A Java transformer for the conversion of Java bytecodes to RISC machine instructions
• Advanced, scalable implementations of garbage collection, object allocation, and
synchronization
• The Remote Abstract Window Toolkit implementation that supports the java.awt APIs
The AS/400 Developer Kit for Java is not an integrated language environment (ILE) language.
It introduces a new language environment on AS/400 that is built on Java, American National
Standard Code for Information Interchange (ASCII), integrated file system, and other industry
standards.
The AS/400 Developer Kit for Java supports the common JDK tools, such as javac, javadoc,
and jar. There are also CL commands and Operations Navigator interfaces to the AS/400
Developer Kit for Java.
Beginning with V4R3, JDK 1.1.6 was supported. Support for JDK 1.1.7 was added with V4R4
in February 1999.
AS/400 Developer Kit for Java V4R5 Enhancements
Options for Java 1.1.8 and Java2 Standard Edition (J2SE) 1.2.2 are shipped with the AS/400
Developer Kit for Java. Options for Java 1.1.6 and 1.1.7 can be enabled on V4R5 by
installing the Developer Kit over the V4R4 version. The concurrent JDK support enables
different versions of Java to be used for application development and deployment on the
AS/400 system. This support should also permit future installation of additional UDK versions
as they become available.
This updated version of AS/400 Developer Kit for Java includes additional performance
improvements, including IBMs 3.5 JIT.
