Answer 1

You have to include a JSF library like for example Mojarra in the classpath of your application.

First of all have a look at the Primefaces user guide (especially chapter 2.2). You can download eg Mojarra here and include the JAR or add the dependency to your POM.xml if you are using Maven. Hope that helps.

Answer 2

If you're using maven for build automation, add the latest jsf-api dependency to your pom.xml:

<dependency>
    <groupId>javax.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.1</version>
</dependency>

Or the latest javax.faces-api implementation :

<dependency>
  <groupId>javax.faces</groupId>
  <artifactId>javax.faces-api</artifactId>
  <version>2.3</version>
</dependency>

However, note that JSF is integrated into most Java EE application servers, such as JBoss.

If you're not using maven you have to manually install the jar. You can download it at this link:

javax.faces

If you're using eclipse you can right click your Web App project and click properties at the bottom. Then under the java build path make sure the libraries panel at the top is selected then select the Web App library and on the right click Add External JARS. You can go to your downloads folder and select the jsf-api-2.1.jar and refresh the project and you can now import that annotation.
