RE: DEPLOYMENT

Hi Rana,

In your code you are trying to use a CompoundImpl that you create yourself and then use it to deploy the description.

You cannot create a compound in that way. A component needs to be loaded in memory, deployed and started, and all this needs to be done in the right way. The easies way to do it is to create a component class and a description that deploys it and use the framework for the deployment. Look at examples/spawn. Spawn is a compound that deploys component descriptions, also ArrayCompound

If what you want is to deploy a description from a third party application, the best way to do it is to create a common/ConfigurationDescriptor and use the SFSystem.runConfigurationDescriptor(cfgD) method. You can also have a look at the way the SF Ant tasks do it. 

I have also attached an example that does this in a very simplify way. You need to have a sfDaemon running before trying the example.

The steps are:

- Get a component description that you want to deploy
- Get a Compound that is already deployed: 
	In this case I use the sfDaemon 
- Ask that compound to deploy the description for you.

It is not clear to me what you are trying to achieve, Could you explain it a bit so that I can help you? 

Regards, 
	Julio

New DeployExample:

public class DeployExample {

    public static void main(String[] args) {      
        try {
            // Init SF System
            org.smartfrog.SFSystem.initSystem();
            // Get an DEPLOYED component. In this case the sfDaemon in local host.
            Compound cp = SFProcess.getRootLocator().getRootProcessCompound(InetAddress.getByName("localhost"),3800);                
            
            // Get a ComponentDescription
            ComponentDescription cd = ComponentDescriptionImpl.sfComponentDescription("/org/smartfrog/examples/pong/singlePlayer.sf");
            
            // Deploy the component description        
            Prim p = cp.sfCreateNewApp("Application_Hola_Pong", cd, null);
                  
            System.out.println(" We just deployed: "+ p.sfCompleteName());
            
        } catch (SFGeneralSecurityException ex) {
            ex.printStackTrace();
        } catch (SmartFrogException ex) {
            ex.printStackTrace();
        } catch (Exception ex){
            ex.printStackTrace();
        }
    }
}
