53. 2006 JavaOne SM Conference | TK 2006 | 53 Dependency Injection ● Example of Inversion of Control ● Container “injects” resources... ● DataSource, EJB ref, web service ref, persistence units, UserTransaction, env entries,... ●... into application... ● Fields, methods; public, private, or protected ●... in container-managed classes ● EJBs, servlets, JSF managed beans, web service endpoints, handlers, interceptors, app clients ● Avoids the need to use JNDI TS-1969 Wed. 4:00

54. 2006 JavaOne SM Conference | TK 2006 | 54 J2EE 1.4 Resource Lookup ● public class MyEJB implements SessionBean { private DataSource myDS; public void ejbCreate() { try { InitialContext ctx = new InitialContext(); myDS = (DataSource)ctx.lookup( “employeeDatabase”); } catch (NamingException ex) { // XXX – what to do? }... ● } ● Plus corresponding deployment descriptor entry

55. 2006 JavaOne SM Conference | TK 2006 | 55 Dependency Injection ● package com.example; ● @Session ● public class MyEJB { @Resource private DataSource myDS;... ● } ● Declares a resource named com.example.MyEJB/myDS ● And injects it into the myDS field ● No deployment descriptor entry needed!

56. 2006 JavaOne SM Conference | TK 2006 | 56 Dependency Injection ● package com.example; ● @Session ● public class MyEJB { @Resource(name = “employeeDatabase”) private DataSource myDS;... ● } ● Declares a resource named employeeDatabase ● And injects it into the myDS field ● Still no deployment descriptor entry needed!

57. 2006 JavaOne SM Conference | TK 2006 | 57 Dependency Injection ● package com.example; ● @Session ● public class MyEJB { @Resource(mappedName = “OracleDatabase”) private DataSource myDS;... ● } ● Declares a resource that's mapped to the app server's global resource named OracleDatabase ● And still no deployment descriptor entry needed!

60. 2006 JavaOne SM Conference | TK 2006 | 60 Application Packaging ● Packaging is now much simpler ● Many cases don't require deployment descriptors ● EJB jar file ● Web application using only JSP, web services ● Application client ● Enterprise application (ear file)

61. 2006 JavaOne SM Conference | TK 2006 | 61 Web Application Packaging Example ● app.war index.jsp images/logo.gif WEB-INF/classes/MyWebService.class ● That's it! ● No META-INF/web.xml ● No META-INF/webservices.xml ● No JAX-RPC mapping file

62. 2006 JavaOne SM Conference | TK 2006 | 62 Enterprise Application Packaging ● Rules and conventions make for simpler packaging ●.war files are web applications ●.rar files are resource adapters ● lib directory contains shared jar files ●.jar with Main-Class is an app client ●.jar file with @Stateless is an EJB

63. 2006 JavaOne SM Conference | TK 2006 | 63 Enterprise Application Packaging Example ● app.ear lib/shared.jar ui/web.war ui/client.jar biz/ejb.jar ● That's it! ● No META-INF/application.xml
