# Enabling JAX-WS in an existing project

Enabling JAX-WS adds the required builders, natures and classpath entries to a project.

To enable JAX-WS in an existing Java or Web project:

1. Select the project in the Package Explorer.
2. Choose JAX-WS > Enable JAX-WS from the menu bar.

Once you have a JAX-WS project you need to add annotations to your classes and methods.
