Good afternoon, you guys!

Here’s the thing: I’m with a JSF application that if I build it from Maven (Maven install) and get the . War generated and der deploy on it by Tomcat, runs normally. However, I cannot run directly through the eclipse using the same installation as Tomcat. Launches java.lang.ClassNotFoundExceptionto the dependencies.

One of them: 

GRAVE: Error configuring application listener of class [org.jboss.weld.environment.servlet.Listener]

In this case, the dependency is as follows in the web xml.:

   <listener>
        <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
    </listener>

and in the pom.xml:

<dependency>
   <groupId>org.jboss.weld.servlet</groupId>
   <artifactId>weld-servlet</artifactId>
   <version>2.4.2.Final</version>
   <scope>runtime</scope>
</dependency>

I am not able to understand the reason of error of these dependencies when running for eclipse, but on the server it compiles normally. If anyone can shed a light...

java jsf eclipse tomcat

Well, after a lot of research, I discovered the problem: I needed to include the Maven dependencies in the assemblies to be compiled by Eclipse when starting the server from the IDE.

To do this:

  1. Right click on the project - Preferences.
  2. Deployment Assembly. Click on Add.
  3. Java Build Path Entries. Next.
  4. Select Maven Dependencies and apply.
