Web-enabling with Java 13

Web-enabling Open. VMS Data & Applications JAVA Based technologies – JAVA, Java Beans, Enterprise Java Beans – Servlets – Java Server Pages (JSPs) – JDBC 14

Enterprise Java. Beans - EJB • • • Jave. Beans are components that can be used to build Java Applications. Using Java. Beans to create a server application, you have to build the entire server framework EJBs provide a model for a services framework into which Java components can be portably deployed With Enterprise Java. Beans the framework is provided for you (by the EJB software) Customization is not performed at development time using properties, but at runtime (deployment time) using a ‘deployment descriptor’ JBs and EJBs are the components used to web-enable VMS data and applications 16

Java Servlets • Servlets are programs written in Java to extend the functionality of HTTP servers • Servlet is to Web server as Applet is to Web browser • Replacement for CGI scripts and programs Why Servlets and not CGI? • Servlets are faster and scale with multiprocessors (Java Threading) • Servlet API is consistent and standard (don’t have to learn for each platform) • Supported by all major Web servers and Engines • User Session Tracking built in (e. g. , for Shopping Carts) 17

Java Server Pages Mix HTML with dynamically generated content from Servlets • Separate ‘Form’ from ‘Function’ or ‘Designers’ from ‘Developers’ • Allows Web page designers to design – Developers to develop – This… Produces <UL> <LI>Time: <%= new java. util.

Webservices 30

Defining Web Services • A Web service is a chunk of functionality that can be accessed using Web technology – Across an intranet or the Internet • Usually: – What’s accessed is a method in a language such as Java or Visual Basic. NET – The Web technology used is the Simple Object Access Protocol (SOAP) carried over HTTP • Both the. NET and Java camps have endorsed Web services 31

Web Services Technologies • Simple Object Access Protocol (SOAP) – An XML-based way to invoke Web services • Web Services Description Language (WSDL) – An XML-based language for describing Web services • Universal Description, Discovery, and Integration (UDDI) – A registry for Web services • Global XML Web Services Architecture (GXA) – Infrastructure Protocol Framework (Microsoft) 32

e. Xtensible Markup Language - XML • A tag-based textual format for: Document mark-up – Data – Standard • Rigorous, so easy to parse (relative to HTML) • – • well-formed versus valid Unfettered by legacy ad-hoc ‘standards’ 33

e. Xtensible Markup Language - XML Defines semantics, not display • HTML defines display, not semantics • <p><b>January 26 th 1998</b></p> • – • HTML defining some text - but giving no meaning to it <Change. Date>January 26 th 1998</> – XML defining a date, but not saying how it should be displayed 34

XML for Open. VMS XML C++ Technology Version 2. 0 for Open. VMS is based on Apache Xerces C Version 2. 2. 0 and Apache Xalan C Version 1. 5. • XML Java Technology Version 2. 0 for Open. VMS is based on Apache Xerces-Java Version 2. 3. 0 and Apache Xalan-Java Version 2. 4. 1. • XML Technology for Open. VMS supports Java and C++ and comprises the following components: • XML Parser in Java and C++ Based on the Apache XML Project's Xerces, which provides parsing and generation. The fully validating parser implements the W 3 C XML and DOM (Level 1 and 2) standards. – XSLT Stylesheet Processor in Java and C++ Based on the Apache XML Project's Xalan, which provides highperformance XSLT – 35

SOAP – The Cornerstone of Interoperability Simple – self-describing messages requests based on proven conventions. SOAP is not simple. But, it is much simpler than any of its predecessors (DCOM, CORBA, DCE, …) Object – has its roots as a way of invoking COM objects across the Internet. SOAP can invoke methods across the Internet. Access – Possible to create SOAP bindings for almost any protocol. The de facto binding is currently HTTP or SMTP, allowing SOAP through most firewalls. Protocol – Put all the previous factors together: • Simple • Object • Access – and you get a very flexible, XML-based protocol for exchanging information throughout a distributed environment 36

SOAP Toolkit for Open. VMS™ Alpha™ V 1. 1 • SOAP Toolkit for Open. VMS™ Alpha™ – Version 1. 1 – Based on Apache SOAP Version 2. 3. 1 and includes Xerces-J • Support – Support for the SOAP Toolkit Version 1. 1 for Open. VMS Alpha is provided by Compaq under existing Open. VMS service agreements through standard support channels – For technical feedback to the SOAP Toolkit for Open. VMS engineering team, please send mail to Open. VMSSoap. Toolkit@hp. com – Exchange information with other users through comp. os. vms • System Requirements • Operating System Alpha Open. VMS Version 7. 2 -2 (or higher) Note: The SOAP Toolkit runs on Open. VMS Version 7. 2 -1, but is officially supported only on Version 7. 2 -2 and higher 37

SOAP Toolkit for Open. VMS™ Alpha™ V 1. 1 SOAP Client prerequisites – Compaq Software Development (SDK) for the Java™ Platform Version 1. 2. 2 -3 (or higher) – All patches required for Compaq SDK for the Java™ Platform. Check the Compaq SDK documentation for the version of Java you are installing to be sure that you have all prerequisite Open. VMS Alpha patches. – Installing on an ODS-5 enabled disk is recommended. Because of long file names and directory depth issues, the installed code base and the accompanying documentation cannot be guaranteed to function properly in a non-ODS 5 environment SOAP Server Prerequisites – All of the SOAP Client prerequisites – Compaq Secure Web Server Version 1. 1 -1 (or higher) for Open. VMS Alpha – CSWS_JAVA Version 1. 0 (or higher) for Compaq Secure Web Server for Open. VMS Alpha 38

. NET • • • . NET is Microsoft’s Web services architecture. NET is based on XML, SOAP, WSDL and UDDI. NET provides a set of Web services, called Hailstorm, together with a security scheme called Passport. NET also provides a development environment and runtime for creating more Web services. NET servers are Microsoft’s pre-existing servers (like Biztalk) brought under the. NET marketing umbrella All this is the basis for Microsoft’s fee-for-use software strategy 40
