Get database result as a type of complex object

Question

Hi,
I would like to make a query and send the results with web service to the client by a user defined object type. I send the servis and client code below. My query works fine but I got all array elements of my object equal to null. I could not understand the reason.
Could you look and help me to solve it please?
Server Code:
import com.sun.rowset.CachedRowSetImpl;
import java.sql.SQLException;
public class deneme3 {
public datayeni hesapla(datayeni don){
int counter = 0;
CachedRowSetImpl crs=null;
SQLInterface iface = new SQLInterface();
if (!iface.execQuery("SELECT isim, soyisim, email, " +
"kart FROM musteri"))
System.exit(1);
// create CachedRowSet and output data to object data
try
crs = new CachedRowSetImpl();
crs = iface.getRowSet();
     if(crs != null)
     while (crs.next())
     counter++;
     int j = 1;     
     int i = 0;                         
     don.setisim(i,crs.getString(j++)) ;
     System.out.println (don.getisim(i));
     don.setsoyisim(i,crs.getString(j++)) ;
     System.out.println (don.getsoyisim(i));
     don.setemail(i,crs.getString(j++)) ;
     System.out.println (don.getemail(i));
     don.setkart(i,crs.getString(j++)) ;
     System.out.println (don.getkart(i));          
     i++;
} catch (SQLException se) {        
     return don;
The Client Code:
import org.apache.axis.AxisFault;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.utils.Options;
import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;
public class deneme3_Client {
public static void main(String [] args) throws Exception {
Options options = new Options(args);
String ad[]=new String[10];
String soyad[]=new String[10];
String eposta[]=new String[10];
String card[]=new String[10];
datayeni obje_return = new datayeni();
Service service = new Service();
Call call = (Call) service.createCall();
QName qn = new QName( "urn:BeanService", "datayeni" );
call.registerTypeMapping(datayeni.class, qn,
new org.apache.axis.encoding.ser.BeanSerializerFactory(datayeni.class, qn),
new org.apache.axis.encoding.ser.BeanDeserializerFactory(datayeni.class, qn));
call.setTargetEndpointAddress( new java.net.URL(options.getURL()) );
call.setOperationName( new QName("deneme3", "hesapla") );
call.addParameter( "arg1", qn, ParameterMode.INOUT );
call.setReturnType( qn );
datayeni ret = new datayeni();
obje_return = (datayeni) call.invoke( new Object[] {obje_return} );
int i = 0;
for (i = 0;i<4;i++)
     ad[i] = obje_return.getisim(i);
     System.out.println(ad);     
     soyad[i] = obje_return.getsoyisim(i);
     System.out.println(soyad[i]);
     eposta[i] = obje_return.getemail(i);
     System.out.println(eposta[i]);
     card[i] = obje_return.getkart(i);
     System.out.println(card[i]);
And the code for the class datayeni:
public class datayeni{
//attributes
private String isim[]=new String[10];
private String soyisim[]=new String[10];
private String email[]=new String[10];
private String kart[]=new String[10];
//setter methods
public void setisim (int index,String isim)
     this.isim[index] = isim;
public void setsoyisim (int index,String soyisim)
     this.soyisim[index] = soyisim;
public void setemail (int index,String email)
     this.email[index] = email;
public void setkart (int index,String kart)
     this.kart[index] = kart;
//getter methods
public String getisim(int index)
     return this.isim[index];
public String getsoyisim(int index)
     return this.soyisim[index];
public String getemail(int index)
     return this.email[index];
public String getkart(int index)
     return this.kart[index];
Thank You!!!

I really wonder, how ur code got compiled ...
Try removing this four lines from ur clinet side code:
String ad[]=new String[10];
String soyad[]=new String[10];
String eposta[]=new String[10];
String card[]=new String[10];Now
your all get methods return String...but u are assigning that string to
array of strings like :
ad = obje_return.getisim(i);
soyad = obje_return.getsoyisim(i);
eposta = obje_return.getemail(i);
card = obje_return.getkart(i);instead write it like this:
String ad = obje_return.getisim(i);
String soyad = obje_return.getsoyisim(i);
String eposta = obje_return.getemail(i);
String card = obje_return.getkart(i);If above thing doesnt work ....
I am very sure problem is not with webservice..its between jumbling of string/int and arrays of respective...
because when u define new array of objects(in ur case: array of Strings), all newborn strings are initlialized to null.
