This example shows how to create an Zend Framework based SOAP Server and connect to it by a Java Client. The process itself is really easy but some things ara a bit tricky for example at the status were i created it there were some problems if using WS style for the SOAP Server so i decided to use RPC style. The Server basically allows a user to logon by credentials and gives back a userstatus, the Java Client is connecting through this service and requesting the userstatus.
The Soap Server Class
<?php
// orginal code has phpdoc compatible comments with slash star
//
// SoapUserServer Class
//
// @author
//
//
// Description of SoapUserServer
//
// @author johny
//
class Example_SoapUserServer {
//
//
// Returns Api Version
// @return string getApiVersion
//
public function getApiVersion()
{
$apiVersion="0.9.3";
return $apiVersion;
}
//
// getUser
// Returns user Status for a given Username, Password combination
// @param string $username
// @param string $password
// @return string getUserResponse
//
public function getUser($username, $password){
$adapter = new Example_AuthAdapter($username,$password);
$userStatus=false;
//retrive login
$auth = Zend_Auth::getInstance();
$auth->authenticate($adapter);
$acl = new Zend_Acl($auth);
if (!$auth->hasIdentity()) {
//user not valid
$userStatus=false;
}else{
//user okay
//@todo dynamic membership types
$membership=$auth->getIdentity()->getMembership();
if($membership && $membership->getMembershipTypeId()>=1){
$userStatus="premiummember";
}else{
$userStatus="normalmember";
}
}
if($userStatus!=false){
return $userStatus;
}else{
return "wrong credentials";
}
}
}
?>
Zend Controller for the Soap Server
<?phpclass SoapController extends Zend_Controller_Action
{ // // Zend Soap Server Action // Representing the soap Server /// public
function serverAction
(){ if(isset($_GET['wsdl'])) { $autodiscover =
new Zend_Soap_AutoDiscover
();
$autodiscover->
setBindingStyle(array('style' =>
'rpc'));
$autodiscover->
setClass('Example_SoapUserServer');
$autodiscover->
handle();
exit;
} // disabling WSDL cache cause we are still in Development ini_set("soap.wsdl_cache_enabled",
"0");
$server =
new SoapServer
('http://example.com/soap/server?wsdl');
$server->
setClass('Example_SoapUserServer');
$server->
handle();
$this->_helper->
viewRenderer->
setNoRender();
$this->_helper->
layout->
disableLayout();
}}?>
Java Client Code
With Netbeans a webservice client is really easy to create, right click on the project create new "Web Service Client"
More Information:
http://netbeans.org/kb/docs/websvc/jax-ws.html
JAX RPC Style works better with Zend Framework and PHP.
The Stub and Port classes will be Auto generated by Netbeans, so you don´t need to worry about that.
