This topic describes how to install the Application Client for
WebSphere Application Server using the installation image on the product CD-ROM.
Before you begin
Running client applications
that communicate with a WebSphere Application Server requires that elements
of the Application Server are installed on the system on which the client
applications run. However, if the system does not have the Application Server
installed, you can install Application Client, which provides a stand-alone
client run-time environment for your client applications.
See
the Supported Prerequisites page for more information on
supported product platforms.The steps that follow provide enough detail to guide you through
preparing for, choosing, and installing the variety of options and features
provided. To prepare for installation and to make yourself familiar with installation
options, complete the steps in this topic and read the related topics, before
you start to use the installation tools. Specifically, read these topics before
installing the product:
As a general rule, if you launch
an installation and there is a problem such as not having enough temporary
space or not having the right packages on your Linux or UNIX systems, then
cancel the installation, and make the required changes. Restart the installation
to initiate your changes.
Although
it is not supported or recommended, you can install this product as a non-root
user on a UNIX operating system. However, you must use a user ID that is part
of the administrator group on Windows platforms.
In Version 6.x, the Application Client for
WebSphere Application Server is installable on a machine with a previous version
of Application Clients. However, you cannot install a Version 6.x Application
Client on top of a previous version of the Application Client.

For
example, if a Version 5 Application Clients install under the
C:\WebSphere\AppClient directory,
you can not choose the same install location for your V6.x Application Clients
installation.
Note: For Application Clients to coexist,
there is a limitation on Applet client and ActiveX client on Windows that
can not be coexisted with V5.0.x and V4.x of the clients. For example, the
Applet client feature in Version 6.x cannot coexist with the Applet client
feature in any previous release. This coexistence is not available because
the installation of Applet client feature in Version 6.x sets the browser
default Java Virtual Machine (JVM) using the Java Runtime Environment (JRE)
from the Version 6.x installation, which is Java Runtime Environment Version
1.4.2. Similarly, the ActiveX to EJB Bridge feature in Version 6.x sets the
Windows system path to use the JRE from the Version 6.x installation.
