Managing Information Access to an Enterprise Information System Using J2EE and Services Oriented Architecture

304 Managing Information Access to an EIS Using J2EE and Services Oriented Architecture

Working with the Chapter6and9 sample files

The ch06and09projects.zip contains projects that can be imported into

WebSphere Studio Application Developer Integration Edition V5.1.1 and the

ch06and09workspace.zip can be extracted to a WebSphere Studio Application

Developer Integration Edition workspace that contains the same projects. The

The projects are:

򐂰 IMSConnector

򐂰 IMSServiceEAR

򐂰 IMSServiceEJB

򐂰 Servers

򐂰 TraderEISCompEAR

򐂰 TraderEISCompEJB

򐂰 TraderLogEJB

򐂰 TraderSP

򐂰 TraderSPEAR

򐂰 TraderSPEJB

򐂰 TraderSPWeb

򐂰 J2C Tool Plugin Import Service

Note that the samples.zip file contains many of the same projects found in the

ch06and09projects.zip, but it also has modelling and design files. You should

extract the samples.zip file to a temporary folder. It contains:

򐂰 A readme.doc file

򐂰 ITSO Residency.zip

This file contains the business process models developed to describe the

Stock Trade scenario. It is a WebSphere Business Integration Modeler export

file. It contains the business items Analysis Details, Order Details, and Trade

Details. It includes process models Stock Analysis, Stock, Brokerage, and

Stock Trade.

򐂰 JMSJCADesign.zip

The file contains the EJB code model for the Trader EIS Component

developed with XDE developer. The code model includes the StockOrderBO,

StockOrderRequest, and StockOrderConfirmation java classes. It also

contains the TraderIMSFeature EJB and the TraderIMSIntegration EJB. UML

diagrams as shown in 6.4, “Develop EIS integration using JMS” on page 137

have been created from this model.

Appendix A. Deploying the sample code 305

򐂰 IMSService.jar

The file contains the IMS access code generated with WebSphere Studio

Application Developer Integration Edition. It includes:

– The WSDL files including the IMS binding: Trader.wsdl, TraderIMS*.wsdl

– The utility classes: INPUT, OUTPUT, WSIF Format Handlers

– The proxy class to call the IMS transaction: TraderProxy.java

– The JUnit test class to test the proxy: TraderProxyTest.java

򐂰 TraderEISCompEAR.ear

This EAR file contains the TraderEISCompEJB module and utility Jars

required to compile the module (IMSService.jar, IMSServiceEJB.jar). The

TraderEISCompEJB module includes the following EJBs:

– The IMS feature session bean: TraderIMSFeature

– The EIS component session bean: TraderIntegration

– The MDB that processes incoming messages and calls TraderIntegration:

TraderIntegrationMDB

– The session bean to sent the reply back to clients: TraderReply

򐂰 IMSServiceEAR.ear

This EAR file contains the client code for the EIS component. The EJBs have

been used to test the Trader EIS component. Later they have also been

included in the Trader system process (BPEL) to call the EIS component. The

EAR includes utility JARS required to compile the module (IMSService.jar,

TraderEISCompEJB.jar) and the IMSServiceEJB module which has the

following EJBs:

– The session bean to create and send the JMS request to the Trader EIS

component: TraderIntegrationTest

– The MDB to receive and log the reply from the EIS component:

TraderRepl yTest

򐂰 TraderLogEJB.jar

The EJB module contains the two EJBs used to log the request message sent

to the EIS component (see 9.4.1, “Transaction support” on page 289s). The

module contains:

– The entity bean used to log the request in the database: LogCMP

– The session that creates the LogCMP objects on request: LogSB

򐂰 TraderSPService.zip

The zipped file that contains the service project with BPEL process and

WSDL definitions. It includes:

– The BPEL system process: TraderSystemProcess.bpel

– The WSDL interface of the BPEL process: TraderSPInterface.wsdl

– The service description of the J2C IMS service: TraderEIS*.wsdl

– The service description of the EIS component (EJB):

TraderIntegration(EJB)*.wsdl

– The service description of the EIS component (JMS):

TraderIntegrationSend(EJB)*.wsdl

– The service description of the Log service: LogRequest(EJB).wsdl

– The XML schema definitions of the business objects used in the WSDL

files: *.xsd
