WSO2
WSO2

The document discusses different programming languages that can be used to develop SOA applications and web services. It recommends C and C++ as they provide better performance than other languages like PHP and Java. It then provides code examples of developing a secure web service and client in PHP and C++ using the WSO2 web services framework. The framework supports various WS-* specifications and allows building fast and secure web services in C/C++.

SOA Workshop Santa Clara Language of your choice  You must have Freedom to choose  You must have Reasons to choose
SOA Workshop Santa Clara Why C?  Most portable  Less memory  Faster  Many interesting applications written in C  HTTPD  Ruby  MySQL  PHP
SOA Workshop Santa Clara Why C++?  Widely used (and some legacy)  Financial, Banking, Telco, DBMS, Embedded  Performance, Flexibility, Control
SOA Workshop Santa Clara Why PHP?  Installed on over 20 million websites  1 million web servers  Easiest way to write services and clients
SOA Workshop Santa Clara SOA in a Heterogeneous World

SOA Workshop Santa Clara PHP Example – Secure Service 1. function echoFunction($inMessage) { 2. $returnMessage = new WSMessage($inMessage->str); 3. return $returnMessage; 4. } 1. $pub_key = ws_get_cert_from_file("../keys/alice_cert.cert"); 2. $pvt_key = ws_get_key_from_file("../keys/bob_key.pem"); 1. $operations = array("echoString" => "echoFunction"); 1. $sec_array = array("encrypt" => TRUE, "algorithmSuite" => "Basic256Rsa15", 2. "securityTokenReference" => "IssuerSerial"); 1. $actions = array("http://php.axis2.org/samples/echoString" => "echoString"); 1. $policy = new WSPolicy(array("security"=>$sec_array)); 2. $sec_token = new WSSecurityToken(array("privateKey" => $pvt_key, 3. "receiverCertificate" =>$pub_key)); 1. $service = new WSService(array("actions" => $actions, 2. "operations" => $operations, 3. "policy" => $policy, "securityToken" => $sec_token)); 1. $service->reply();
SOA Workshop Santa Clara PHP Example – Secure Client 1. $rec_cert = ws_get_cert_from_file("../keys/bob_cert.cert"); 2. $pvt_key = ws_get_key_from_file("../keys/alice_key.pem"); 1. $reqMessage = new WSMessage($reqPayloadString, array("to"=> 2. "http://localhost/samples/security/encryption/encrypt_service.php", 3. "action" => "http://php.axis2.org/samples/echoString")); 1. $sec_array = array("encrypt"=>TRUE, "algorithmSuite" => "Basic256Rsa15", 2. "securityTokenReference" => "IssuerSerial"); 1. $policy = new WSPolicy(array("security"=>$sec_array)); 2. $sec_token = new WSSecurityToken(array("privateKey" => $pvt_key, 3. "receiverCertificate" => $rec_cert)); 1. $client = new WSClient(array("useWSA" => TRUE, "policy" => $policy, 2. "securityToken" => $sec_token)); 1. $resMessage = $client->request($reqMessage); 1. printf("Response = %s n", $resMessage->str);

SOA Workshop Santa Clara  Designed for embedding within C or C++ software stacks to enable Web services  All-in-one solution for the building and deploying of Web services  Widest range of WS-* specifications implementations  WS-Addressing, WS-Policy, WS-Security, WS- SecurityPolicy, WS-Reliable Messaging, MTOM and WS-eventing
SOA Workshop Santa Clara C++ Example - Service 1. #include <ServiceSkeleton.h> 1. using namespace wso2wsf; 1. class Echo: public ServiceSkeleton 2. { 3. public: 4. WSF_EXTERN WSF_CALL Echo(){}; 1. OMElement* WSF_CALL invoke(OMElement *message, MessageContext *msgCtx); 1. OMElement* WSF_CALL onFault(OMElement *message); 1. void WSF_CALL init(){}; 2. }; 1. OMElement* Echo::invoke(OMElement *element, MessageContext *msgCtx) 2. { 3. OMElement *echoElement = new OMElement(element->getLocalname(), 4. new OMNamespace(element->getNamespace(false)->getURI(), 5. element->getNamespace(false)->getPrefix())); 6. OMElement *textElement = new OMElement("messsage"); 7. echoElement->addChild(textElement); 8. textElement->setText("Hello World"); 9. return echoElement; 10. }
SOA Workshop Santa Clara C++ Example - Client 1. ServiceClient serviceClient(client_repo, end_point); 1. OMNamespace * ns = new OMNamespace("http://ws.apache.org/rampart/c/samples", "ns1"); 2. OMElement * payload = new OMElement(NULL, "echoIn", ns); 3. OMElement * child = new OMElement(payload, "message", NULL); 4. child->setText("Hello Service!"); 1. try 2. { 3. OMElement* response = serviceClient.request(payload, 4. "http://example.com/ws/2004/09/policy/Test/EchoRequest"); 5. if (response) 6. { 7. cout << endl << "Response: " << response << endl; 8. } 9. } 10. catch (AxisFault & e) 11. { 12. if (serviceClient.getLastSOAPFault()) 13. { 14. cout << endl << "Fault: " << serviceClient.getLastSOAPFault() << endl; 15. } 16. else 17. { 18. cout << endl << "Error: " << e << endl; 19. } 20. } 21. delete payload;
