CDI deployment failure:WELD-001414 Bean name is ambiguous

Question

I have an application, which has multiple modules and various dependencies. When I deploy the application on Glassfish 4, I am getting error:

org.jboss.weld.         


        

Answer 1

Are you by any chance packaging the Jersey specific libraries in your EAR file. I believe glassfish does provide the Jersey libraries and you do not need to package them.

Answer 2

I think you have two @Named bean class with the same name.

Answer 3

Glassfish is already having Jerseys libraries packaged for you, so you need add provided scope into your Maven pom.xml as stated in the docs.

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0</version>
    <scope>provided</scope>
</dependency>

If you are using any Jersey specific feature, you will need to depend on Jersey directly.

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.4.1</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.4.1</version>
    <scope>provided</scope>
</dependency>
