Action (XWork: Core 2.3.24.1 API)

All Known Implementing Classes:

ActionSupport
```
public interface Action
```
All actions may implement this interface, which exposes the execute() method.
However, as of XWork 1.1, this is not required and is only here to assist users. You are free to create POJOs that honor the same contract defined by this interface without actually implementing the interface.
