What’s in WSDP
  • Java Architecture for XML Binding (JAXB)
    • Providing API and tools for automating the mapping between XML documents and Java objects;
    • Compiling an XML schema into one or more Java technology classes;
    • The following operations can be performed:
      • unmarshal XML content into a Java representation;
      • access, update and validate the Java representation against schema constraint;
      • marshal the Java representation of the XML content into XML content.

  • Java Architecture for XML Binding (JAXB)
what s in wsdp7
What’s in WSDP
  • Java API for XML Processing (JAXP)
    • supports processing of XML documents using DOM, SAX, and XSLT;
      • Document Object Model (DOM): an application programming interface for HTML and XML documents;
      • Simple API for XML (SAX): a common interface implemented for many different XML parsers;
      • XSL Transformations (XSLT): a language for transforming XML documents into other XML documents;
    • supports for XML schema and an XSLT compiler (XSLTC);
what s in wsdp8
What’s in WSDP
  • Java API for XML-Based RPC (JAX-RPC)
    • an API for building Web services and clients that use remote procedure calls (RPC) and XML ;
    • an easy-to-develop programming model for development of SOAP based web services, including web service clients and endpoints;
      • developers are not exposed to the complexity of SOAP protocol level mechanisms;
    • support for WSDL->Java and Java->WSDL mapping;
    • support for SOAP message processing model;
    • support for document based messaging;
    • support HTTP level session management and SSL based security mechanisms.

What’s in WSDP
  • Java API for XML-Based RPC (JAX-RPC)
what s in wsdp10
What’s in WSDP
  • SOAP with Attachments API for Java (SAAJ)
    • enables developers to produce and consume messages conforming to the SOAP 1.1 specification and SOAP with Attachments note;
    • derived from the package originally defined in the JAXM 1.0 specification;
    • SOAP messages can contain both XML contents and non-XML contents (as attachments);
    • Messages sent using the SAAJ API are called request-response messages;

  • SOAP with Attachments API for Java (SAAJ)
what s in wsdp12
What’s in WSDP
  • Java API for XML Registries (JAXR)
    • provides a uniform and standard Java API for accessing different kinds of XML Registries;
      • ebXML Registry and Repository standard;
      • Universal Description, Discovery, and Integration (UDDI);
    • JAXR enables Java software programmers to use a single, easy-to-use abstraction API to access a variety of XML registries. A unified JAXR information model describes content and metadata within XML registries;

What’s in WSDP
  • JavaServer Faces Technologies
    • a server-side user interface framework for Java technology-based Web applications ;
    • Main components include:
      • A set of APIs for:

representing UI components and managing their state;

handling events and input validation;

defining page navigation;

supporting internationalization and accessibility .

      • A JavaServer Pages (JSP) custom tag library for expressing UI components within a JSP page.

  • JavaServer Pages Standard Tag Library (JSTL)
    • encapsulates core functionality common to many JSP applications;

What’s in WSDP
  • XML and Web Services Security
    • Transport-Level Security

security is addressed by the transport layer.

      • Basic Authentication with JAX-RPC;
      • Client-Certificate Authentication over HTTP/SSL with JAX-RPC;
    • Message-Level Security

security information is contained within the SOAP message.

what s in wsdp19
What’s in WSDP
  • Java WSDP Registry Server
    • The Java Web Services Developer Pack (Java WSDP) Registry Server implements Version 2 of UDDI;
    • provide a UDDI registry for Web services in a private environment;
    • use it with the Java WSDP APIs as a test registry for Web services application development.
an example
An Example
  • The Coffee Break server obtains the
  • coffee varieties and their prices by
  • querying distributors at startup and
  • on demand.
  • The Coffee Break server uses SAAJ messaging to communicate with one of its distributors.
  • The Coffee Break server uses JAXR to send a query searching for coffee distributors that support JAX-RPC to the Registry Server.
  • The Coffee Break server requests price lists from each of the coffee distributors.
  • The Coffee Break server forwards
  • suborders to each distributor to get
  • confirmations.
  • Coffee Break Application
an example coffee break
An Example-Coffee Break
  • JAX-RPC Distributor Service
    • Service side
      • Service Interface

public interface SupplierIF extends Remote {

public ConfirmationBean placeOrder(OrderBean order)

throws RemoteException;

public PriceListBean getPriceList() throws RemoteException;

}

      • Publishing the Service in the Registry

JAXRPublisher publisher = new JAXRPublisher();

publisher.makeConnection(queryURL, publishURL);

String key = publisher.executePublish(username, password, endpoint);

an example coffee break22

  • JAX-RPC Distributor Service
    • Client side
      • Building the Static Stub Client;

Clients makes remote call through a stub, a local object which acts as a proxy for the remote service.

wscompile -gen:client -d build -classpath build config-wsdl.xml

-gen:client flag instructs wscompile to generate the stubs;

-d: flag tells the tool to write the output to the build subdirectory;

config-wsdl.xml file: specifies the location of the WSDL file;

      • Invoking the remote method

PriceListBean priceList = PriceFetcher.getPriceList(distributor);

an example coffee break23
An Example-Coffee Break
  • SAAJ Distributor Service
    • SAAJ Service
      • Returning the Price List

public void doPost(HttpServletRequest req, HttpServletResponse resp)

{

…Analyze the request…

…Compose the message…

OutputStream os = resp.getOutputStream();

reply.writeTo(os);

os.flush();

}

      • Returning the Order Confirmation

  • SAAJ Distributor Service
    • SAAJ Client

SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance(); SOAPConnection con = scf.createConnection();

……

Compose the request

……

SOAPMessage response = con.call(request, endpoint);

an example coffee break25
An Example-Coffee Break
  • Coffee Break Server

The Coffee Break Server uses servlets, JSP pages, and JavaBeans components to dynamically construct HTML pages for consumption by a Web browser client.

    • RetailPriceListServlet & RetailPriceList
      • The RetailPriceListServlet responds to requests to reload the price list;
      • Component RetailPriceList
        • Discovering the JAX-RPC Service

JAXRQueryByName jq = new JAXRQueryByName(); connection = jq.makeConnection(queryURL, publishURL); jq.executeQuery(queryString);

        • Query JAX-RPC service and SAAJ service
    • CheckoutFormBean

submits suborders to each distributor
