Chapter 14 Working with Java

Reverse engineering servlets

You can reverse engineer servlet code and deployment descriptor into an OOM. The reverse engineering feature reverses the Java class as a servlet class, it reverses the servlet as a component, and associates the servlet class with this component. The reverse engineering feature also reverses the deployment descriptor and all the files inside the WAR.

You start reverse engineering servlet from Language→Reverse Engineer Java.

Select one of the following Java formats from the Selection page, and select the Reverse Engineer Deployment Descriptor check box from the Options page:

• Java directories
• Class directories
• Archive (.JAR file)

For more information on the Java formats, see section Reverse engineering Java formats in chapter Reverse engineering.

   For more information on merging models, see section Merging Models, in chapter Comparing and Merging Models in the General Features Guide .
8. Click OK.
   
   The Reverse page of the Output window displays the changes that occurred during reverse and the diagram window displays the updated model.
