[news.eclipse.dsdp.tm] RSE:How to set timeout to stop the connecting sta

[he.meihua@xxxxxxxxxx (hemeihua )]

I creat a FTP connection with the specified port such as 8092 which has 
been used by other applications,and connect the FTP connection,but can not 
open a Socket connected to a remote host at the specified port(8092) by 
indirectly call {@link org.apache.commons.net.SocketClient$connect(String 
hostname, int port)},and keep on connecting state for ever. 

Here is my configuration:
- Windows XP PC running Eclipse 3.3.0 with plugin RSE (RSE-SDK-3.0.1.zip)

Here are my code:
/*creat a FTP connection with the specified port such as 8092*/
public IHost creatFTPConnection(String siteName, String ip, int port ){
		IHost ftpSite = null;
		IRSESystemType systemType = 
RSECorePlugin.getTheCoreRegistry().getSystemTypeById(RSE_SYSTEM_TYPE_ID);
		ISubSystemConfigurator[] configurators = getSubSystemConfigurators();
		String[] defaultProfileNames = 
sr.getSystemProfileManager().getActiveSystemProfileNames();	
		String aliasName = decorateAliasName(siteName);
		
		if(defaultProfileNames.length > 0){
			try {
				ftpSite = sr.createHost(defaultProfileNames[0], systemType, aliasName, 
ip,
						"", "", 0,configurators);
			} catch (Exception e) {
				e.printStackTrace();
			}
			if(ftpSite != null){
				ISubSystem[] subsystems = ftpSite.getSubSystems();
				for (int i = 0; i < subsystems.length; i++){
					ISubSystem subsystem = subsystems[i];
					subsystem.getConnectorService().setPort(port);//port=8092
			    }
			}
		}
		return ftpSite;
	}

/*to connect the FTP connection with the specified port such as 8092*/	
public class ConnectAllJob extends Job
	{
		private IHost fFtpSite, fTabDate;
		private Viewer fViewer; 
		public ConnectAllJob(IHost site,IHost data, Viewer v )
		{
			super(SystemResources.ACTION_CONNECT_ALL_LABEL);
			fFtpSite = site;
			fTabDate = data;
			fViewer = v;
		}
		
		public IStatus run(IProgressMonitor monitor)
		{			
		    List failedSystems = new ArrayList();
			try 
			{
			    //forced instantiation of all subsystems
			    ISubSystem[] subsystems = fTabDate.getSubSystems();
			    for (int i = 0; i < subsystems.length; i++)
			    {
			        ISubSystem subsystem = subsystems[i];
			        IConnectorService system = subsystem.getConnectorService();
			        if (!subsystem.isConnected()
			          && 
subsystem.getSubSystemConfiguration().supportsSubSystemConnect()
			          && !failedSystems.contains(system))
			        {
			            try
			            {
			                subsystem.connect(monitor, false);
			            }
						catch (SystemMessageException e) {
							//TODO should we collect all messages and just show one dialog with 
a MultiStatus?
			                failedSystems.add(system);
							SystemMessageDialog.displayMessage(e);
						}
						catch (Exception e) {
			                failedSystems.add(system);
			                if ((e instanceof InterruptedException) || (e 
instanceof OperationCanceledException)) {
				                // if the user was prompted for password and cancelled
				                // or if the connect was interrupted for some other 
reason
				                // we don't attempt to connect the other subsystems
								break;
			                }
							SystemBasePlugin.logError(
									e.getLocalizedMessage()!=null ? e.getLocalizedMessage() : 
e.getClass().getName(),
									e);
							
							SystemMessageDialog.displayErrorMessage(getShell(), e.getMessage());
						}
			        }
			    }
			} 
			catch (Exception exc) 
			{
			} 	// msg already shown	
			if (failedSystems.size() > 0)
			{
				return Status.CANCEL_STATUS;
			}
		}
	}
How to set timeout to stop the connecting state or what is the best way to 
handle this problem? 
Somebody can help me?
