J2EE Connector architecture establishes contracts amongst the application, the resource adapter and the application server, where the application will eventually be deployed. These contracts imply that all the participating components are J2EE Connector architecture compliant for the sake of working together. The application contract is nothing more than the definition for the communication between connector and the application. The system contract defines the connection management, transaction management and the security management. Application Application Contract Connector or Resource Adapter EIS-specific interface Enterprise Information System (EIS) Container contract System contract -Connection management -Transaction management -Security management Application Server Connection Manager Transaction Manager Security Manager Figure 7-27 J2EE Connector architecture The security contract enables the application server to connect to an Enterprise Information System using security properties. The application server authenticates with the EIS system by using the security properties the user credentials. There are two different methods the application server can authenticate to an Enterprise Information System. ► Container-managed sign-on: the security properties are configured when the resource adapter is deployed on the application server. Again there are several ways to configure security properties here. With Configured Identity all resource adapter connections use the same identity when connecting to the Enterprise Information System. With Principal Mapping the principal used when connecting to the Enterprise Information System based on a combination of the current principal in the application server and the mapping. With Caller Impersonation the principal used in the Enterprise Information 170 IBM WebSphere V5.0 Security Handbook
► System exactly matches the principal in the application server. With Credentials Mapping the type of credentials must be mapped from application server credentials to Enterprise Information System credentials. Though it is easy to have container-managed sign-on, there is little flexibility as it is not possible to change the security properties in runtime. Component-managed sign-on allows you to pass security configuration properties each time a connection is acquired from the resource adapter. 7.3.2 Java 2 Connector security The Enterprise Information System stores very important information and the information must be protected from unauthorized users. Java 2 Connector architecture is designed to address the security of connection to Enterprise Information System. The application server and the Enterprise Information System collaborate to ensure the proper authentication of a resource principal which establishes a connection to an underlying enterprise information system. Connector architecture supports the following authentication mechanisms: ► ► BasicPassword: Basic username-password based authentication mechanism specific to enterprise information system. Kerbv5: Kerberos version 5 based authentication model WebSphere Application Server V5 Java 2 Connector supports basic password model currently. Kerberos authentication model will be supported in the near future. The user ID and password for the target EIS is either supplied by applications or by the application server. WebSphere Application Server uses the JAAS pluggable authentication mechanism to perform principal mapping to convert WebSphere principal to resource principal. WebSphere Application Server provides a DefaultPrincipalMapping LoginModule, which basically converts any authenticated principal to the pre-configured EIS resource principal and password. Subsequently, you can plug in your own principal mapping LoginModule using the JAAS plug-in mechanism. The user ID and password can either be configured using the Administrative Console or can be sent to the Enterprise Information System programmatically. Using J2C Authentication Data Entries for Datasource First, you will have to create a new J2C entry for WebSphere. In order to create the appropriate entry for this section follow the configuration steps from 10.7.2, “J2C Authentication data entries” on page 257. Chapter 7.
