Release 10.1A: OpenEdge Getting Started:
Installation and Configuration

Java considerations

Many OpenEdge products require the Java Run-time Environment (JRE), the Java Development Kit (JDK), or both of these components to use specific product functionality once the products are installed.

JDK component

The JDK contains the software and tools that developers need to compile, debug, and run applets and applications written using the Java programming language. The JDK software and documentation, typically included with each new release of an operating system, are available for download at the vendor’s Web site. You need a JDK if you intend to develop Java stored procedures and triggers with the database.

OpenEdge products that require the JRE component

The JRE consists of the Java Virtual Machine, the Java Core Classes, and supporting files. The JRE is the run-time part of the JDK and does not include a compiler, a debugger, or development tools. You will need the JRE if you intend to use one of the following:

Progress Explorer.
WebSpeed® Transaction Server.
OpenEdge® Application Server – Basic Edition.
OpenEdge® Application Server – Enterprise Edition.
Java application or applet.
Web Services Adapter.
Secure AppServer™ Internet Adapter (AIA).

You will also need the JRE to execute Java stored procedures and triggers from the OpenEdge database.

Additional Java considerations

Note these additional Java considerations:

Depending on which products you choose to install, the installation process might not automatically update your system with the JRE and the JDK. For example, the installation program does not automatically install the JDK component when you install any of these products: the OpenEdge® RDBMS Enterprise Edition, the OpenEdge® RDBMS Workgroup Edition, or when you install the OpenEdge® RDBMS Personal Edition with the OpenEdge® SQL Client Access.
If you intend to develop Java stored procedures and Java triggers for your database, you must install an OpenEdge development product such as OpenEdge® Studio. For information on writing Java stored procedures and triggers, see OpenEdge Data Management: SQL Development and OpenEdge Data Management: SQL Reference .

JRE and JDK requirements by platforms

Table 1–1 lists operating systems and specifies the versions of JDK and JRE each supports. When Javasoft provides a JDK and JRE for a certain platform, Progress Software Corporation includes the JDK and JRE in its distribution. For other systems, you must obtain the JDK from the system’s operating system vendor. Please contact your operating system vendor for assistance in obtaining the JDK.
