You have to create the object and then assign to the parameters.  I have had these kind of similar problems when i started off with the webservices.

The following should work...

>>  Object[] params = { account, deposit };


Object[] params = new Object[2];
params[0] = new Integer(account);
params[1] = new Double(deposit);

This would help... try this out...

even you have to do the same for i == 3 section too

Otherwise... that won't work too

try this,

else if (i == 2)
                   {
                         System.out.println("Enter Account: ");
                         String account = reader.readLine();
                         Integer intAccount = new Integer(account);
                         
                         System.out.println("Enter Deposit: ");
                         String deposit = reader.readLine();
                         Double dblDeposit = new Double(deposit);
                         
                         call.setOperationName(new QName(BODY_NAMESPACE_VALUE, "deposit"));
                         call.addParameter("int_1", QNAME_TYPE_INTEGER, ParameterMode.IN);
                         call.addParameter("double_2", QNAME_TYPE_DOUBLE, ParameterMode.IN);
                         Object[] params = { intAccount, dblDeposit };

                         String result = (String)call.invoke(params);
                         System.out.println(result);
                    }
