Question

Answer 1

+1 A:

This should indeed work, the slf4j-log4j12 binding contains org/slf4j/impl/StaticLoggerBinder.

Try to clean and redeploy your application, maybe something went wrong during deployment.
Double check that the downloaded slf4j-log4j12-1.5.8.jar is not corrupted (try to open it).
Maybe even delete it and let maven re-download it.

Some unrelated remarks:

Instead of repeating frameworks version in dependencies, you should use a property. For example:

...
<properties>
  <spring.version>3.0.2.RELEASE</spring.version>
  ...
</properties>
<dependencies>
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>${spring.version}</version>
  </dependency>
  ...
</dependencies>

hibernate-core is a transitive dependency of hibernate-annotations, you don't need to declare it (if you want to use JPA, you should actually depend on hibernate-entitymanager).

1. done several times - no success here2. the file is ok - I can open it in eclipse or per fs3. tried this too - no success too.I tried instead of `slf4j-log4j12`other bindings with no effect. I only get this exception

Answer 2

+3 A:

Include the slf4j-api in your dependencies:

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>1.5.8</version>
</dependency>

Exclude the commons-logging dependency for minimum one of your declared spring dependencies and provide the slf4j facade for commons-logging:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
  <version>3.0.2.RELEASE</version>
  <exclusions>
     <exclusion>
       <groupId>commons-logging</groupId>
       <artifactId>commons-logging</artifactId>
     </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>jcl-over-slf4j</artifactId>
  <version>1.5.8</version>
  <scope>runtime</scope>
</dependency>

Include the log4j dependency for your logging together with the slf4j facade:

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>1.5.8</version>
  <scope>runtime</scope>
</dependency>
<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.14</version>
  <scope>runtime</scope>
</dependency>

A great blog post for further reading about logging with SLF4J and Spring can be found in the SpringSource Team blog under http://blog.springsource.com/2009/12/04/logging-dependencies-in-spring/.

Following this advices worked out - now I'm getting another exception. Well its a step forward.

asrijaal 2010-06-13 15:49:00

Is it still any logging related exception?

codescape 2010-06-13 15:53:45

No, now it is `java.lang.ClassNotFoundException: javassist.util.proxy.MethodFilter` importing javassist dependcy doesn't works... Think I just let this world burn...

Answer 3

A:

You are missing

  <dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.5.8</version>
  </dependency>

That's a transitive dependency of Hibernate, the OP has this dependency.

Answer 4

+1 A:

Hibernate depends on slf4j-api, so declaring it yourself shouldn't make any difference. Apart from that, I don't know why it's not working.
