Client Software Requirements

This release of Instant Messaging supports any XMPP-compliant client in addition to Instant Messenger. The jabber.org website has a full list of XMPP-compliant clients.

On Windows, you can run Instant Messenger using the browser’s Java plug-in from the following browsers:

• Netscape 4.7x, 7 or later

• Mozilla 1.2 or later

• Internet Explorer 5.0 or later

If the client machine has Java 1.4 or a higher version installed, there are no additional requirements to use either Java Plug-in or Java Web Start. Netscape Navigator v7 as well as the recent versions of the Mozilla browser include Java v1.4 or higher. Internet Explorer does not include the latest version of Java. If you experience problems using the client with Java 1.4, upgrade to 5.0. JDK 5.0 is included with Sun Java System Instant Messaging.

If the client machine does not have Java v1.4 or a higher version installed, you need to install it. You can download and install Java v1.4. from the following location:
