Question

Answer 1

A:

Make sure your bean is in a bean archive - i.e. that you have META-INF/beans.xml

Apart from the weld extension, which I can't help you with unless you give the whole exception, you can create a producer that @Produces a Logger

I was using mvn dependency for <groupId>org.jboss.weld</groupId> <artifactId>weld-logger</artifactId> <version>1.0.0-CR2</version> <groupId>org.jboss.weld</groupId> <artifactId>weld-extensions</artifactId> <version>1.0.0.Alpha1</version> <groupId>org.jboss.weld</groupId> <artifactId>weld-api</artifactId> <version>1.0-CR2</version> <groupId>org.jboss.weld</groupId> <artifactId>weld-core</artifactId> <version>1.0.1-CR2</version>Something else?

Answer 2

A:

The default slf4j logger producer is defined in Weld Extensions. You can see how the producer is written here if you wanted to wire up your own without including all of Weld Extensions.

Answer 3

+1 A:

This is my approach:

Add the following dependencies to the pom.xml:

<!-- SL4J API -->
 <dependency>
 <groupId>org.slf4j</groupId>
 <artifactId>slf4j-api</artifactId>
 <version>1.6.0</version>
 </dependency>

 <!-- SLF4J JDK14 Binding  -->
 <dependency>
 <groupId>org.slf4j</groupId>
 <artifactId>slf4j-jdk14</artifactId>
 <version>1.6.0</version>
 </dependency>

 <!-- Injectable Weld-Logger -->
 <dependency>
 <groupId>org.jboss.weld</groupId>
 <artifactId>weld-logger</artifactId>
 <version>1.0.0-CR2</version>
 </dependency>

Inject the Logger and use it as usual:

import javax.inject.Inject;
import org.slf4j.Logger;

public class Example {
  @Inject
  private Logger logger;

  public void exampleFunc() {
    logger.info("Hello Logger!");
  }
}

If you wanna use Log4J instead of the SLF4J-JDK14-binding, i found this page. I tried it, but i couldn't get it to work so i still stick with my own solution.
