= Creating a Server-Side Component
Typical server-side Vaadin applications use server-side components that are
rendered on the client-side using their counterpart widgets. A server-side
component must manage state synchronization between the widget on the
client-side, in addition to any server-side logic.
[[gwt.server-side.basic]]
== Basic Server-Side Component
The component state is usually managed by a __shared state__, described later in
<<gwt-shared-state#gwt.shared-state,"Shared
State">>.
[source, java]

public class MyComponent extends AbstractComponent {
public MyComponent() {
getState().setText("This is MyComponent");
}
@Override
protected MyComponentState getState() {
return (MyComponentState) super.getState();
}
}
