Add slf4j dependency with Ant to Spring 4.0 application

Question

I'm using spring 4.0 and I've started with the hello world example. When I ran the examples, I just got this exception,

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
    at org.springframework.context.support.AbstractApplicationContext.<init>(AbstractApplicationContext.java:153)
    at org.springframework.context.support.GenericApplicationContext.<init>(GenericApplicationContext.java:100)

    at hello.service.main.Main.main(Main.java:14)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 5 more

But I read that if we are not using commons logging and I want to use slf4j then I just want to add slf4j logging jar in the classpath. I've added that also.

Please help me in resolving the issue.

To use slf4j your pom.xml must include following set of dependencies

     <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.0.0.RELEASE</version>
        <scope>runtime</scope>
        <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>
    <dependency>
        <groupId>org.slf4j</groupId>

download commons-logging.jar and add it to your class-path.

http://commons.apache.org/proper/commons-logging/download_logging.cgi

download the zip file commons-logging-1.1.3-bin.zip and extract commons-logging.jar, add it to classpath, will solve the issue.

But in spring documentation it is mentioned that commons logging can also be avoided http://docs.spring.io/spring/docs/4.0.0.RELEASE/spring-framework-reference/htmlsingle/#overview-logging-slf4j – vvekselva Dec 24 '13 at 09:15

Just add the jcl-over-slf4j.jar file to your libraries. See slf4j docu for the details.
