<package name="default" namespace="/" extends="struts-default">
    <action name="login">
        <result>/menu/login.jsp</result>
    </action>

    <action name="authendicate" class="com.rajesh.Authendicate" method="verify">
        <result>/menu/success.jsp</result>
    </action>
</package>

We can provide four parameters with package declaration.

1. name        –        Name of the package (required)
2. namespace   –   Namespace for the actions in the package
3. extends     –      Parent package to inherit
4. abstract    –       If true this package will only be used to define inheritable components not actions. (Discuss in detail later)

• The main use of packages are we can group similar actions together.
• We can inherit one packages options to another one simply by extending it.
• An example is we can group all the actions that required authentication, then by adding particular rule for that package alone we can control the unauthorized access.

Most of the Struts 2 Framework default classes and functionality methods are grouped into packages. We can make use of those by simply extend it. See our example code above, we extended the “struts-default” package where major struts 2 default implementations are available.
