Verifying an Enterprise Application

See Also 

Before you deploy an enterprise application or any stand-alone web or EJB module to the Sun Java System Application Server, you should verify it, to ensure it is properly implemented to the J2EE 1.4 specification. The verifier tool validates both J2EE and application server-specific deployment descriptors against their corresponding DTD files and gives errors and warnings if a module or application is not J2EE and Sun Java System Application Server compliant. You can verify deployment descriptors in EAR, WAR, RAR, and JAR files.

The verifier tool is not simply an XML syntax verifier. Rules and interdependencies between various elements in the deployment descriptors are verified. Where needed, classes in your module are examined to ensure that what is referred to in the deployment descriptors actually exists and will work when deployed.

To verify a project deployment descriptors:

  1. Right-click any web application module, EJB module, or enterprise application project in the Projects window and choose Verify. The target server for the project must be the Sun Java System Application Server.

    The Verifier window opens and displays all the results.

  2. Filter the results according to your needs:
  3. Make appropriate changes, if any, and verify the project again.
