  1. Oracle (BEA) Web Logic Introduction Presented by: Chunyan Fu PhD, Researcher at Ericsson Chunyan.fu@ericsson.com INSE 7110 Winter 2009

  2. Agenda • Tool overview • How to install and use • A real case tutorial • Hints for the project INSE 7110 Winter 2009

  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 INSE 7110 Winter 2009

  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 INSE 7110 Winter 2009

  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 INSE 7110 Winter 2009

  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: • http://e-docs.bea.com/wlw/docs103/index.html • http://e-docs.bea.com/wls/docs103/webservices.html INSE 7110 Winter 2009

  7. 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 INSE 7110 Winter 2009

  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 INSE 7110 Winter 2009

  9. How to download SIP Stack • JSR 32 Jain SIP • API doc and .jar can be downloaded at: • http://jcp.org/aboutJava/communityprocess/mrel/jsr032/index.html • Unzip • Reference implementation .jar can be downloaded at: • http://download.java.net/communications/jain-sip/nightly/ • 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) • http://www.apache.org/dyn/closer.cgi/logging/log4j/1.2.15/apache-log4j-1.2.15.zip INSE 7110 Winter 2009

  10. Course Project:SDS 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) • What’s in common: • Media handling: RTP/RTCP (JMF) • Conference client: SIP client that talks RTP INSE 7110 Winter 2009
