The problems you are seeing are caused by the order you are calling
the methods.
1. addWebapp() will create the necessary Engine and Host but these
need to be in place before you call start().
2. There is no need to call init(). Calling start() will call init()
if it hasn't already been called.
The following should work:
Tomcat tomcat = new Tomcat();
tomcat.setBaseDir(baseDir);
tomcat.getConnector().setPort(8080);
tomcat.getServer().setParentClassLoader(getClass().getClassLoader());
tomcat.addWebapp("", path);
tomcat.start();
Patches for improvements to the Tomcat Javadoc welcome.
The Tomcat unit tests are a good source of examples of using the
Tomcat class.
