     <h1>
       Creating a Java application launch configuration
     </h1>
     <p>
       When you choose <strong>Run &gt;Run As &gt;Java Application </strong>to
       launch your class, you are running your class using a generic <strong>Java
       Application</strong> launch configuration that derives most of the launch
       parameters from your Java project and your workbench preferences.&nbsp; In
       some cases, you will want to override the derived parameters or specify
       additional arguments.
     </p>
     <p>
       You do this by creating your own <strong>Java Application</strong> launch
       configuration.&nbsp;
     </p>
     <ol>
       <li>
         Select <strong>Run &gt;Run... </strong>or <strong>Run &gt;Debug...</strong>
         from the workbench menu bar.&nbsp; This opens a dialog that lets you
         create, modify, and delete launch configurations of different types.
       </li>
       <li>
         Select <strong>Java Application</strong> in the left hand list of launch configuration types, and press <strong>New</strong>. This will create a new launch configuration
         for a Java application.&nbsp;The tabs on the right hand side allow you
         control specific aspects of the launch.
       </li>
     </ol>
     <blockquote>
       <ul>
         <li>The <strong>Main</strong> tab defines the class to be launched. Enter the name of the project containing the class to launch in the project field, and the fully qualified
         name of the main class in the the Main class field.&nbsp;Check the <strong>Stop
           in main</strong> checkbox if you want the program to stop in the main method
           whenever the program is launched in debug mode.<br>
         Note:&nbsp; You do not have to specify a project, but doing so allows a
         default classpath, source lookup path, and JRE to be chosen.</li>
         <li>The <strong>Arguments</strong> tab defines the arguments to be passed to the application and to the virtual machine (if any).
           You can also specify the working directory to be used by
         the launched application.</li>
         <li>The <strong>JRE</strong> tab defines the JRE used to run or debug the application.
           You can select a JRE from the already defined JREs, or define a new
           JRE.</li>
         <li>The <strong>Classpath</strong> tab defines the location of class files used when running or debugging an application. By default, the user and bootstrap class locations
         are derived from the associated project's build path. You may
           override these settings here.</li>
         <li>The <strong>Source</strong> tab defines the location of source files used to display source when debugging a Java application. By default, these settings are derived from
         the associated project's build path. You may override these settings
           here.</li>
         <li>The <strong>Common</strong> tab defines general information about
           the launch configuration.&nbsp; You may choose to store the launch
           configuration in a specific file and specify which perspectives become
           active when the launch configuration is launched.</li>
       </ul>
