May I didn't do the properly project settings for a right execution...
Could some body help me?
Thanks a lot in advance.
Pablo.

This is the Batch.class:
package bcbatch;
import oracle.jbo.*;
import oracle.jbo.client.*;
import oracle.jbo.domain.Number;
public class Batch
public Batch()
public static void main(String[] args)
if (args.length==0)
show("Customer ID is required.");
System.exit(0);
//new Batch();
ApplicationModule am_Ord = Configuration.createRootApplicationModule("OnlineOrders.OnlineOrdersModule", "OnlineOrdersModuleLocal");
ViewObject vo=am_Ord.findViewObject("CustomersView1");
Key custKey = new Key(new Object[] {args[0]});
Row[] customersFound = vo.findByKey(custKey,1);
if (customersFound.length==0)
show("Customer " + args[0] + " not found.");
else
Row row_Cust = customersFound[0];
show("Customer");
show("========");
show("ID: " + row_Cust.getAttribute("CustomerId"));
show("Email: " + row_Cust.getAttribute("CustEmail"));
private static void show(String s)
System.out.println(s);
} // end show()
