Hi, You will have to download the "J2EE 1.4 Tutorial Update 2 (for Sun Java System Application Server Platform Edition 8 Update 1) June 22, 2004". The link is http://java.sun.com/j2ee/1.4/previous_downloads.html. You will find it at the bottom of the page.
You can find a tutorial about the Dukeâs Bank on http://www.student.nada.kth.se/~d95-cro/j2eetutorial14/doc/Ebank.html The first thing you have to do is protecting the Web Client Resources. I have used MySQL as follow, #1.- Create two tables -users, with two fields (username, passwd) and fill the table with the users as your own. In my case I followed the tutorial, username passwd 200 j2ee admin admin and some other users that I have created on the desktop client. I mean (201, 201), (164, 164), etc where user and pass are the same value -userroles, with two fields (username, userRoles) and fill the table as follow username userRoles 200 bankCustomer admin bankAdmin and the rest of the users with the role bankCustomer. #2.- The next step is setup the datasource and security policy on JBoss In your mysql-ds.xml, in the directory jboss-4.2.2.GA\server\default\deploy create de datasource as follow, | <datasources> | <local-tx-datasource> | <jndi-name>DefaultDS</jndi-name> | <connection-url>jdbc:mysql://localhost:3306/yourDB</connection-url> | <driver-class>com.mysql.jdbc.Driver</driver-class> | <user-name>yourUser</user-name> | <password>yourPasswd</password> | <exception-sorter-class-name> | org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter | </exception-sorter-class-name> | <metadata> | <type-mapping>mySQL</type-mapping> | </metadata> | </local-tx-datasource> | </datasources> | And the security policy, in the directory jboss-4.2.2.GA\server\default\conf\login-config.xml, as follow, | <application-policy name="dukesbank"> | <authentication> | <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required"> | <module-option name="dsJndiName">java:/DefaultDS</module-option> | <module-option name="principalsQuery"> | select passwd from Users where username=? | </module-option> | <module-option name="rolesQuery"> | select userRoles,'Roles' from UserRoles where username=? | </module-option> | </login-module> | </authentication> | </application-policy> | #3.- Now the structure of our application I have developed the application on Eclipse 3.2.2 IDE so my tree is as follow, The root of the application will be the name of it. I named it JBossDukesBank. So, | JBossDukesBank | src | com.sun.ebank.appclient | BankAdmin.java | DataModel.java | EventHandle.java | AdminMessages_es.properties | AdminMessages.properties | com.sun.ebank.ejb.account | Account.java | AccountBean.java | AccountController.java | AccountControllerBean.java | AccountControllerHome.java | AccountHome.java | com.sun.ebank.ejb.customer | Customer.java | CustomerBean.java | CustomerController.java | CustomerControllerBean.java | CustomerControllerHome.java | CustomerHome.java | com.sun.ebank.ejb.exception | (All the ejb exception classes) | com.sun.ebank.ejb.tx | Tx.java | TxBean.java | TxController.java | TxControllerBean.java | TxControllerHome.java | TxHome.java | com.sun.ebank.util | AccountDetails.java | CodedNames.java | CustomerDetails.java | DateHelper.java | DBHelper.java | Debug.java | DomainUtil.java | EJBGetter.java | TxDetails.java | com.sun.ebank.web | AccountHistoryBean.java | ATMBean.java | BeanManager.java | ContextListener.java | CustomerBean.java | DateHelper.java | Dispatcher.java | TransferBean.java | WebMessages_en.properties | WebMessages_es.properties | WebMesages.properties | com.sun.ebank.web.template | Debug.java | Definition.java | DefinitionTag.java | InsertTag.java | Parameter.java | ParameterTag.java | ScreenTag.java | Now you have to import the jars. From the folder /server/default/lib all jars and from /client/, jboss-client.jar, jbossall-client.jar and jbossws-common.jar. I am not sure if needed but my app works ok. Following, I have created some other folders on the structure tree. The dd (deployment descriptors) folder, | dd | client | application-client.xml | jboss-client.xml | client-app | application.xml | ejb | ejb-jar.xml | web-app | application.xml | dd/client/application-client.xml.- | <?xml version="1.0" encoding="UTF-8"?> | | <!DOCTYPE application-client PUBLIC | '-//Sun Microsystems, Inc.//DTD J2EE Application Client 1.3//EN' | 'http://java.sun.com/dtd/application-client_1_3.dtd'> | <application-client> | <display-name>BankAdmin</display-name> | <ejb-ref> | <ejb-ref-name>ejb/CustomerControllerEJB</ejb-ref-name> | <ejb-ref-type>Session</ejb-ref-type> | <home>com.sun.ebank.ejb.customer.CustomerControllerHome</home> | <remote>com.sun.ebank.ejb.customer.CustomerController</remote> | </ejb-ref> | | <ejb-ref> | <ejb-ref-name>ejb/AccountControllerEJB</ejb-ref-name> | <ejb-ref-type>Session</ejb-ref-type> | <home>com.sun.ebank.ejb.account.AccountControllerHome</home> | <remote>com.sun.ebank.ejb.account.AccountController</remote> | </ejb-ref> | | <ejb-ref> | <ejb-ref-name>ejb/TxControllerEJB</ejb-ref-name> | <ejb-ref-type>Session</ejb-ref-type> | <home>com.sun.ebank.ejb.tx.TxControllerHome</home> | <remote>com.sun.ebank.ejb.tx.TxController</remote> | </ejb-ref> | </application-client> | dd/client/jboss-client.xml.- | <jboss-client> | <jndi-name>bank-client</jndi-name> | | <ejb-ref> | <ejb-ref-name>ejb/AccountControllerEJB</ejb-ref-name> | <jndi-name>accountController</jndi-name> | </ejb-ref> | | <ejb-ref> | <ejb-ref-name>ejb/CustomerControllerEJB</ejb-ref-name> | <jndi-name>customerController</jndi-name> | </ejb-ref> | | <ejb-ref> | <ejb-ref-name>ejb/TxControllerEJB</ejb-ref-name> | <jndi-name>txController</jndi-name> | </ejb-ref> | | </jboss-client> | dd/client-app/application.xml.- | <?xml version="1.0" encoding="UTF-8"?> | <application xmlns="http://java.sun.com/xml/ns/j2ee";
