Introduction

This document describes how to check the exact Java version that is active on your PC. This is useful if you need to troubleshoot Cisco Transport Controller connection problems.

Cisco Transport Controller is a Java application that is launched from an Internet browser and runs as a standalone process on a Microsoft Windows or Solaris computer. Cisco Transport Controller makes use of the Java Runtime Environment (JRE) provided by Sun Microsystems. The JRE provides Cisco Transport Controller with a Java Virtual Machine (JVM) and a standard set of application program interfaces (APIs).

Check the Java Version

Complete these steps to check the Java version that runs on a PC:

1. Open a DOS window.

Select Start > Accessories > Command Prompt.

2. Change the directory to c:\Program Files\JavaSoft\JRE\1.3.1_02\bin, where c: and 1.3.1_02 represent the drive where Java was installed and the Java version.

3. Enter java -version at the prompt and make sure that there is a space between "java" and "-version".

This is a sample output:

C:\Program Files|JavaSoft\JRE\1.3.1_02\bin>java -version

java version "1.3.1_02"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)

Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)
