To view .jtx files in your web browser, you must configure your
  web server to use the JT Harness
  harness ExcludeBrowser servlet.
com.sun.javatest.servlets.ExcludeBrowser
Refer to your server documentation for information about configuring it to
  use the harness ExcludeBrowser servlet. Typically, you
  configure the web server to direct .jtx files to the servlet for
  rendering.
