Enterprise JavaBeans - EJB
•
•
•
•
•
JaveBeans are components that can be used to build
Java Applications.
Using JavaBeans 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 JavaBeans 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
page 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)
page 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

Webservices

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
page 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)
page 32
eXtensible Markup Language - XML
•
A tag-based textual format for:
–
–
•
•
Standard
Rigorous, so easy to parse (relative to HTML)
–
•
Document mark-up
Data
well-formed versus valid
Unfettered by legacy ad-hoc ‘standards’
page 33
eXtensible Markup Language - XML
•
•
•
Defines semantics, not display
HTML defines display, not semantics
<p><b>January 26th 1998</b></p>
–
•
HTML defining some text - but giving no meaning to it
<ChangeDate>January 26th 1998</>
–
XML defining a date, but not saying how it should be
displayed
page 34
XML for OpenVMS
•
XML C++ Technology Version 2.0 for OpenVMS is based on
Apache Xerces C Version 2.2.0 and Apache Xalan C Version 1.5.
• XML Java Technology Version 2.0 for OpenVMS is based on
Apache Xerces-Java Version 2.3.0 and Apache Xalan-Java
Version 2.4.1.
• XML Technology for OpenVMS 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 W3C 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
page 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

SOAP Toolkit for OpenVMS™ Alpha™
V1.1
•SOAP
Toolkit for OpenVMS™ 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 OpenVMS Alpha is provided by Compaq
under existing OpenVMS service agreements through standard support channels
– For technical feedback to the SOAP Toolkit for OpenVMS engineering team, please send
mail to [email protected]
– Exchange information with other users through comp.os.vms
•System
Requirements
• Operating System
Alpha OpenVMS Version 7.2-2 (or higher)
Note: The SOAP Toolkit runs on OpenVMS Version 7.2-1, but is officially
supported only on Version 7.2-2 and higher
page 37
SOAP Toolkit for OpenVMS™ Alpha™
V1.1
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 OpenVMS 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-ODS5 environment
SOAP Server Prerequisites
– All of the SOAP Client prerequisites
– Compaq Secure Web Server Version 1.1-1 (or higher) for OpenVMS Alpha
– CSWS_JAVA Version 1.0 (or higher) for Compaq Secure Web Server for
OpenVMS Alpha

.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
