Title: Oracle (BEA) Web Logic Introduction


1
Oracle (BEA) Web Logic Introduction
  • Presented by Chunyan Fu
  • PhD, Researcher at Ericsson
  • Chunyan.fu_at_ericsson.com

2
Agenda
  • Tool overview
  • How to install and use
  • A real case tutorial
  • Hints for the project

3
Tool overview
  • A Free Tool that can be used for developing web
    services
  • Web logic server a server that can deploy web
    services
  • Workshop environment for development

4
Web logic Server
  • A Java EE (5.0) application server
  • That provide a platform for building
  • Web services and many other applications, e.g.
  • Web application (JSP, Servlet), EJB, JDBC, JMS,
    RMI
  • In terms of web service, it supports
  • XML, SOAP, WSDL, UDDI, Web service security
  • Java API for XML-based Web Services (JAX-WS) is
    used
  • JAX-WS is a standards-based API for coding,
    assembling, and deploying Java Web Services

5
Workshop
  • Built on Eclipse 3.3.2 and Web Tools Platform
    2.0.3
  • An extension to Eclipse
  • Workshop version 10.3 is supported by Windows
    Vista

6
Installation
  • http//www.oracle.com/technology/software/products
    /ias/bea_main.html
  • Accept license agreement on the top of the page
  • Click the link
  • Oracle Workshop for WebLogic 10.3 - Package
    Installer OR
  • Oracle Workshop for WebLogic 10.3 - Net
    Installer
  • Sign in or register if you are new
  • Documentations

How to use
  • A concrete example a web service that prints
  • Create a web service project
  • Create project, add to ear
  • Create package
  • Create a web service
  • Add web methods see JAX-WS annotations
  • Add/start web logic server
  • Create a domain
  • Start server
  • Deploy and test web service
  • Run on server
  • Web logic test client
  • See SOAP, WSDL

8
Hints for the project
  • Server side
  • a conferencing web service that implements a
    simplified conference focus
  • uses SIP stack to listen to, receive, process and
    send SIP messages
  • Client side SIP client
  • Download or
  • Code your client using SIP stack
  • Use of JMF for media

9
How to download SIP Stack
  • JSR 32 Jain SIP
  • API doc and .jar can be downloaded at
  • http//jcp.org/aboutJava/communityprocess/mrel/jsr
    032/index.html
  • Unzip
  • Reference implementation .jar can be downloaded
    at
  • http//download.java.net/communications/jain-sip/n
    ightly/
  • Click jain-sip-ri/, you can find all nightly
    build implementations .jar
  • You can also find sdp implementations there
  • When implementing a web service using Jain SIP
    stack, put the two jar files (one api, one impl)
    into your project \WEB-INF\lib
  • jsip_api_v1.2.jar
  • jain-sip-ri-1.2.xx.jar
  • Tip you may need log4j-xxx.jar if you always
    have running errors when using Jain SIP (this
    depends on which sip impl that you use)

Course ProjectSDS or Web Logic ?
  • Ericsson SDS
  • For developing conferencing application in IMS
  • Need to configure IMS first
  • Can use SIP Servlet
  • Trigger from SIP client or HTTP Servlet
  • Both need programming work
  • Conference client registration register to CSCF
  • Oracle Web Logic
  • For developing conferencing application in a
    network (LAN, Internet)
  • Can use SIP Stack (lower level of abstraction
    than SIP Servlet)
  • Trigger from web logic test client or any web
    service that talks SOAP
  • The first option is provided by the tool, no need
    to code
  • Conference client registration register to your
    SIP Listener (in your WS logic)
  • Whats in common
  • Media handling RTP/RTCP (JMF)
  • Conference client SIP client that talks RTP
