Why and when to perform this task
Several assembly tools exist that are graphical user interfaces for assembling enterprise or Java 2 Platform, Enterprise Edition (J2EE) applications. You can use these tools to assemble an application and secure Enterprise JavaBeans (EJB) and Web modules in that application. An EJB module consists of one or more beans. You can enforce security at the EJB method level. A Web module consists of one or more Web resources: an HTML page, a JavaServer Pages (JSP) file, or a servlet. You can also enforce security for each Web resource. You can use an assembly tool to secure an EJB module, a Java archive (JAR) file, a Web module, a Web archive (WAR) file, or an application enterprise archive (EAR) file. You can create an application, an EJB module, or a Web module and secure them using an assembly tool or development tools like the IBM Rational Application Developer.Steps for this task
Result
After securing an application, the resulting .ear file contains security information in its deployment descriptor. The EJB module security information is stored in the ejb-jar.xml file and the Web module security information is stored in the web.xml file. The application.xml file of the application EAR file contains all the roles that are used in the application. The user and group-to-roles mapping is stored in the ibm-application-bnd.xmi file of the application EAR file.The was.policy file of the application EAR contains the permissions granted for the application to access system resources protected by Java 2 security.
This task is required to secure EJB modules and Web modules in an application. This task is also required for applications to run properly when Java 2 security is enabled. If the was.policy file is not created and it does not contain required permissions, the application might not be able to access system resources.
What to do next
After securing an application, you can install an application using the administrative console. When you install a secured application, refer to Deploying secured applications to complete this task.Related concepts
