tomcat via java code

[fahad siddiqui]

I am creating an instance of tomcat via java code using the following snippet.

     public void startTomcat() throws Exception {
        
        Engine engine = null;
        // Set the home directory
        System.setProperty("catalina.home", getPath());
        
        // Create an embedded server
        embedded = new Embedded();
        // print all log statments to standard error
        //embedded.setDebug(1);
        
        embedded.setLogger(new SystemOutLogger());
 
        // Create an engine
        engine = embedded.createEngine();
        engine.setDefaultHost("localhost");
       
        // Create a default virtual host
        host = embedded.createHost("localhost", getPath()+ "\\webapps");
        engine.addChild(host);
        host.setAutoDeploy(true);
        // Create the ROOT context
        Context context = embedded.createContext("",getPath() + "\\webapps\\ROOT");
        host.addChild(context);
        
        // Install the assembled container hierarchy
        embedded.addEngine(engine);
        
        // Assemble and install a default HTTP connector
        System.out.println("Creating connector and Catlina Port="+catlina_port)     ;
        Connector connector = embedded.createConnector("0.0.0.0", catlina_port, false);
        embedded.addConnector(connector);
        // Start the embedded server
        
        embedded.start();
    }

This uses the catlina jar.
My concern is, can i use this instance as a normal tomcat instance for deploying my war files?
I ran this and got an instance of tomcat running on 8080.
Now, i want some other program to deploy a war file on this running server. Is it possible? Because i am not able to.
Please advise on how to?

If i register a war in this class only right after starting the tomcat, it works, but can't i do this from some other class or something at a later point of time?

I use the following snippet for registering the war:

      public void registerWAR(Host host,String contextPath, URL warFile)
    throws Exception {
        
        if ( contextPath == null ) {
            
            throw new Exception("Invalid Path : " + contextPath);
        }
        if( contextPath.equals("/") ) {
            
            contextPath = "";
        }
        if ( warFile == null ) {
            
            throw new Exception("Invalid WAR : " + warFile);
        }
        
        Deployer deployer = (Deployer)host;
        Context context = deployer.findDeployedApp(contextPath);
        
        if (context != null) {
            
            throw new
            Exception("Context " + contextPath
            + " Already Exists!");
        }
        deployer.install(contextPath, warFile);
    }
