Hello, 1. First you go to the command prompt (If you are using Windows) and set the JAVA_HOME and PATH environment variables to jdk path. For executing the installer.jar file, we have to set the PATH variable. For Windows, | >set JAVA_HOME=<jdk home directory path>; | >set PATH=%PATH%;<jdk home directory path>/bin; | For Unix or Linux, | #export JAVA_HOME=<jdk home directory path> | #export PATH=<jdk home directory path>/bin | 2. set the DISPLAY variable. For Windows, | >set DISPLAY=<Your Desktop system's ip-addr>:0 | For Unix or Linux, | #export DISPLAY=<Your Desktop system's ip-addr>:0 | 3. Start the XWindow Manager. 4. Go to the installer.jar file path in command prompt and run the following command. | java -jar jboss-4.0.4.GA-Patch1-installer.jar | It will display the GUI, you can install the JBoss AS of your choice of Server configuration.
