Using JT400.

Ok I'm trying to figure this out.  Here is the code:

import com.ibm.as400.access.AS400;
import com.ibm.as400.access.AS400SecurityException;

class Base extends Object
{

 public static void main(String args[])
 {
        
   int as400number;
   AS400 myas400 = new AS400();
   as400number = AS400.SIGNON;
   
   try {
   myas400.validateSignon();
   }
   catch (AS400SecurityException i) {}
   catch (Exception e){}
   
   ObjectDef iObject = new ObjectDef();
     
   if (args.length == 0) {
         // do nothing
   }
   
   if (args.length == 1) {
     iObject.Name = args[0];
     iObject.Library = "*LIBL";
   }
   
   if (args.length == 2) {
        iObject.Name = args[0];
        iObject.Library = args[1];
   }
   
   if (args.length == 3) {
        iObject.Name = args[0];
        iObject.Library = args[1];
        iObject.ObjectType = args[2];
   }

   System.out.println();
   System.out.println(iObject.Name);
   System.out.println(iObject.Library);
   System.out.println(iObject.ObjectType);
  }
}

According to what I have read when the AS400 myas400 = new AS400(); is
executed I should be prompted for sign on credentials (it's likely
something I have misunderstood).  When it hits that line no prompt
appears and it seems to just step into the com.ibm.whatever and return.
Also if I pass the value *PGM as a variable it replaces the constant
*PGM with the package name.  Please help a newbie....i'll buy a Krystal
burger & we can all split it.

Thanks,
