Verifier GUI mode (invoked by verifier -u) will no longer be available. The equivalent functionality will be available in the NetBeans IDE.
The default mode for application verification when using verifier tool will change from “Verify J2EE rules” to “Verify J2EE rules and Sun Application Server Configuration Rules.” In other words, by default verifier will test whether an application meets J2EE rules and is configured to run on Sun Application Server. The verifier command will have a command-line switch to test an application for J2EE rules only.
