i development a system in my company..and everything work fine...connect to sap without any problem using JCO.Pool


 public IRepository createSapRepository()
  {
  	IRepository repository = null;
  	try {
      // Add a connection pool to the specified system
      //   The pool will be saved in the pool list to be used
      //   from other threads by JCO.getClient(SID).
      //   The pool must be explicitely removed by JCO.removeClientPool(SID)
	  //JCO.getClientPoolManager().setConnectionTimeout(30000);
      //JCO.getClientPoolManager().setMaxWaitTime(60000);
      JCO.Pool pool = JCO.getClientPoolManager().getPool(POOL_NAME);
	  
	  if (pool == null) 
	  {
	  	try
	  	{
	  		// SAP Login information is stored in logon.properties instead of
	  		//   hardcoded in Java Class. Hence, if SAP login infor has to be
	  		//   changed, modify it in logon.properties file 
			LoginProperties loginProperties = 
			LoginProperties.load("logon.properties");
			
			JCO.addClientPool(POOL_NAME, // pool name
			  			 MAX_CONNECTION, // maximum number of connections
						loginProperties); // properties
			
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
	  }
	  
      // Create a new repository
      //   The repository caches the function and structure definitions
      //   to be used for all calls to the system SID. The creation of
      //   redundant instances cause performance and memory waste.
      repository = JCO.createRepository("MYRepository", POOL_NAME);
      //System.out.println("SAP repository created successful..");
    }
    catch (JCO.Exception ex) 
    {
      System.out.println("Error Trace in ConnectionUtilities.getSapRepository:n"
      					 + ex.getMessage());
      ex.printStackTrace();
    }
    return repository;
  }

Hi,

Your company SAP is setup is different. Your home SAP system is a prirated one and it will have nothing of security settings and other settings, maybe does not support connection pool concept itself.

Cheers!!!
