[Archive] Unable to launch Smartpass web GUI



Article ID: KB31644 KB Last Updated: 16 Jun 2020Version: 2.0

This article describes a scenario where the user was unable to launch the Smartpass web GUI. Then after upgrading to Smartpass 9.2, this issue was resolved.


Unable to launch the web GUI of Smartpass.


In this case, the user was unable to launch the Smartpass GUI because they had Java version 1.6. 


In most instances, Ringmaster and Smartpass applications are both installed on the same server (Linux/Windows). If you have Ringmaster version 9.2 and Smartpass versions 9.0/8.0 or earlier, then Smartpass should be upgraded to version 9.2, which supports Java version 1.8, and to launch Smartpass GUI.

Check your Java version in Smartpass and see if it needs an upgrade.

  1. Log on to the server in which Smartpass is installed.

  2. Open the Command Prompt window.

  3. Type the following commands to get into the BIN folder which is placed inside the JRE folder of Smartpass.

    cd Program Files
    cd Trapeze Networks
    cd SmartPass
    cd jre
    cd bin
  4. Execute the following command to verify the Java version:

    C:\Program Files\Trapeze Networks\Smartpass\jre\bin>java -version
