The ParentPackage Annotation has configures the XWork package (an XWork package is created per Java package) to extend the defined package. Multiple packages one or more defined packages. The best place for this annotation is on the package via the package-info.java file, however, for backward-compatibility, they can be specified through annotations on multiple Actions in the package.one or more Actions in the package. To determine which parent packages should be set, first, it looks for the package annotation, then adds the action annotations as they are loaded. Because the load order of Actions is undetermined, it is highly recommended you avoid putting the @ParentPackage annotation on Action classes themselves.

For example, if you wanted to set the parent package for the com.mycompany.myapp.actions package, create this package-info.java file:

@ParentPackage("my-parent-package")
package com.mycompany.myapp.actions

import org.apache.struts2.config.ParentPackage;

To define multiple parent packages, list an array of package names:

@ParentPackage({"my-parent-package1, my-parent-package2"})
package com.mycompany.myapp.actions

import org.apache.struts2.config.ParentPackage;
