使用slf4j和log4j

Question

I am having a problem with slf4j with log4j.

I have a log4j.xml on development environment and it is set to DEBUG.

In my pom.xml I have the following:

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>jcl-over-slf4j</artifactId>
        </dependency>

When I run my code and I use Logger (SLF4J) and I check whether debug is enabled - I get false and if anyway I try to log.debug I don't see the result.

but, if in the same class I use Logger (apache log4j) everything works well as I expect.

I read many posts about the log4j and slf4j but I could not solve it.

Your help is appreciated.

Thanks

Sorry, I found a hint and fixed the problem. I add to change the pom to:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
</dependency>

The mistake was I used slf4j-simple instead of slf4j-log4j12.

Thanks
