“SimpleLogger does not seem to be location aware” exception

[fashoom]

I'm getting an exception in a Spring 2.5 app on my first line of code:

ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");

I have commons-logging-1.1.1.jar configured as a project library.

Here is the stack trace:

java.lang.UnsupportedOperationException: The logger [org.slf4j.impl.SimpleLogger(org.springframework.co ntext.support.ClassPathXmlApplicationContext)] does not seem to be location aware.

You seem to want/be using slf4j (judging from the stacktrace) but also log4j and commons... That is somewhere going to bite you... Remove the commons-logging stuff, -sinclude the jcl-over-slf4j.jar (acts as commons-logging), and either use logback or the log4j binding (you seem to be wanting to use log4j).

This is a Spring/Hibernate project and somehow I had included both a versioned and an unversioned slf4j-simple.jar in the project as part of the Hibernate config. I deleted slf4j-simple.jar, leaving slf4j-simple-1.4.2.jar matching the slf4j-simple-api-1.4.2.jar that is part of the Hibernate distribution I'm using.

It is now working fine w/ commons-logging-1.1.1. I tried removing commons-logging-1.1.1 but Spring complained.
