When I try to cf push, I get an error, so my app won't start:

I fixed this by adding 

    <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
    </dependency>

to my pom.

Hi,

this is interesting. Which java buildpack have you used?

Maybe i had a transitive dependency on it and therefore no issue?

Thanks for clarification. Nena
