## Building
To build the module, use Maven's `package` goal:
```
mvn clean package
```
The `war` file will be available at `target/deep-jsf.war`
## Running
The `war` application is deployed to a Java EE 7 compliant application server, for example, to GlassFish 4 or later.
The example then will be accessible at http://localhost:8080/deep-jsf/index.xhtml
