Usage

From source file:org.apache.catalina.launcher.CatalinaLaunchFilter.java

/**
 * This method allows dynamic configuration and error checking of the
 * attributes and nested elements in a "launch" task that is launching a
 * Catalina application. This method evaluates the nested command line
 * arguments and, depending on which class is specified in the task's
 * "classname" attribute, may force the application to run
 * in the foreground by forcing the "waitforchild" attribute to "true".
 *
 * @param launchCommand a configured instance of the {@link LaunchTask}
 *  class//from   www  .j  av a2  s  .com
 * @throws BuildException if any errors occur
