I tried to run a simple example with JSF and Primefaces but I believe it is something related to some incorrect configuration. The application is running on Tomcat 9.0.13, below the project settings:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.faces</artifactId>

<dependency>

Try to include cdi in your application, put that dependency in pom:
<dependency>
 <groupId>javax.enterprise</groupId>
 <artifactId>cdi-api</artifactId>
 <version>1.2</version>
</dependency>– Adriano Gomes
@Adrianogomes worked, I would like you to create the answer so I give the question as answered, if you would like me to explain what the difference between using cdi-api and Weld would be a hand on the rsrs wheel anyway thanks.
– William.Andrade
I’ve never worked with Weld, so I can’t help you answer that question.
