Hi, I just upgraded from 3.2.6 to 3.3.1. I had some conflicts of packages, and ended up having to upgrade to the following dependancies to get everything to work:

Code:

        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.14</version>
        </dependency>

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.5.6</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.5.6</version>
        </dependency>

Now in IntelliJ IDEA, I get two loggers going at the same time... Spring is using the same logger as before in a black font... and now all the Hibernate messages (validator, core, etc.) is in a burgundy colour. The weird thing is that the output no longer responds to my log4j settings in log4j.properties :(

Can anyone enlighten me as to what happened? Is slf4j using another logger now? I know next to nothing about slf4j, so any advice on how to stop this from happening would be fantastic if you already know. At this moment, I can't spend the 3 hours it might take someone of my ignorance to fix it ;(

Thanks

Okay, I'm convinced my log4j files aren't even being read anymore. They used to be... like before I upgraded some jar files. now rootLogger=OFF doesn't work at all. It must be getting overrided somehow... OR log4j isn't being used. I dunno how to tell if another log system is being used. Not a clue.

Okay, I'm positive slf4j has hijack my original settings. Grrrrrrrr.

I made a test logger like this:

Code:

static Logger logger = org.slf4j.LoggerFactory.getLogger( JobManager.class );

And when I log to it, sure enough, it looks exactly like the other logging information that is being thrown at the screen.

What logger is this?

Code:

Sep 20, 2009 5:07:16 AM org.hibernate.cfg.Environment <clinit>
INFO: Hibernate 3.3.1.GA
Sep 20, 2009 5:07:16 AM org.hibernate.cfg.Environment <clinit>

YES!

Solution:

Code:

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-orm</artifactId>
            <version>${spring.version}</version>
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-jdk14</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

Each that Spring! :/
