Can't call method Java web service from PHP client (in WSDL mode)

Thanks for reply,

 I was trying it since yesterday & i got it without any changes in my WSDL file. here is sample code for that.

require_once('nusoap.php');
  /* create the client for my rpc/encoded web service */
 $wsdl = "http://localhost:8084/webserviceproj/WebServicesService?wsdl";
  $client = new soapclient($wsdl,array('trace' => 1));

/* Initialize parameter */
$params = array('i'=>"ASD");

// Method name
 $response = $client->__soapCall('simple', array('parameters' => $params));
     print_r($response->return);
Now i am trying to connect to DB and return a set of values (array) and capture it in PHP to display it in the client side. from client side i am passing a name "i" whose data i am querying to DB to fetch data. so is there a need to query DB to get data in XML format using XMLELEMENT command in oracle or what  should be done to send back an array of data from JWS

I am using a String Array to store data n send it back to PHP . in .net we have Dataset to fill up data n send it back . sample code is here for (JWS).

public String[] simple(@WebParam(name = "i")
    String i) {       
        String res[] = new String[3];

/// Connection code goes here     
        if(rs.next()){
          res[0] = rs.getString(1) ;
                   res[1]=rs.getString(2) ;
                           res[2]= rs.getString(3);   }

Out put is here :

Array ( [0] => 5 [1] => Adil [2] => hyd )

Response: <?xml version="1.0" ?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">

<S:Body><ns2:simpleResponse xmlns:ns2="http://sample/">

<return>5</return><return>Adil</return>

<return>hyd</return></ns2:simpleResponse></S:Body></S:Envelope>

thanks
