EAServer requires version 1.3.1 of the Java Development Kit (JDK) from Sun Microsystems. You can optionally run servers with JDK 1.4.2 instead. By default, JDK 1.3.1 and the optional JDK versions that you select are installed with EAServer. You can also configure the install to use an existing version, as long as it is of the required patch level as listed in Table 1-1.
JDK version |
Patch level |
Notes |
|---|---|---|
1.3.1 |
11 |
This version is required to run EAServer Manager, jagtool, and other tools. It is also the default for running servers. |
1.4.2 |
06 |
This version is required to run the Web services toolkit. With JDK 1.4, the client and server virtual machines (VMs) are supported; the classic VM is not. |
To verify the version and patch level, open a DOS prompt in the bin directory of the JDK installation and run the following command:
java -version
To configure the installation to use an existing JDK installation, choose the Custom installation type when running the installer. After you select the desired JDK versions, the installer scans your machine for JDK installations that match the selected versions. The installer prompts you to specify whether to use an existing JDK and for the location of the JDK. If an existing JDK has been detected, the location is given as the default in this prompt. You can specify a different location.
