How To Induce Java.Lang.Classnotfoundexception: Org.Apache.Commons.Logging.Logfactory

java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory  or "Exception inward thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory" exception comes when yous don't apache commons-logging-1.1.1.jar inward your Classpath. I accept faced this exception many times piece using open source framework similar Struts, Spring too Displaytag which uses commons-logging framework for logging. commons-logging is non an actual coffee logging framework only provides a wrapper too thence that yous tin role log4j, java logging or any other Java logging framework. commons-logging is too smart plenty to notice which logging framework are yous using e.g if yous are using log4j it tin notice it past times looking log4j.jar inward your classpath. only if yous don't accept commons-logging.jar in your classpath yous may instruct java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at runtime even if your application gets deployed successfully.

Cause of java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

JVM non able to locate commons-logging-1.1.1.jar inward classpath only it may surface differently on dissimilar environment. Some fourth dimension fifty-fifty you get this mistake fifty-fifty if yous already accept commons-logging-1.1.1.jar inward classpath too many times it dissimilar reasons for different environment. It gets to a greater extent than hard on managed surroundings similar J2EE spider web servers too application servers where different classloader loads dissimilar classes e.g. AppClassLoader is responsible for loading spider web application but classes within lib directory of spider web server e.g. tomcat is loaded past times roughly other classloader. So yous tin too get "java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory" if commons-logging.jar is non visible to App classloader. roughly times this jounce tin too crusade memory leak inward tomcat.

here I accept outlined roughly steps to attain "java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory" these are based on approach I used to resolve such sort of error. it may assistance yous equally well.

java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory Solution

1.Check your classpath for commons-logging-1.1.1.jar, if yous are using saltation MVC too working inward spider web application it

must endure on /WEB-INF/lib directory.

2.Check if your Java plan has sufficient permission to access that jounce file (I faced this resultant inward Unix machine

when user who copied that jounce does override the default permission too application was non able to read this jounce file

so brand certain to cheque permissions if yous are copying commons-logging-1.1.1.jar into Java Classpath.

3.See if commons-logging-1.1.1.jar contains org.apache.commons.logging.LogFactory shape or non this may hap if commons-logging-1.1.1.jar is corrupt or non downloaded completely or may endure downloaded from wrong source.

4.See if your Classpath is getting overridden past times whatsoever start-up Script equally suggested on my postal service how to solve java.lang.ClassNotFoundException

5.If yous are using maven for managing dependency on your projection than cheque if your pom.xml file contains following

entry or non too if it doesn't than include next dependency for commons-logging-1.1.1.jar inward pom.xml:

Maven dependency for Apache commons-logging:

<dependency>

        <groupId>commons-logging</groupId>

        <artifactId>commons-logging</artifactId>

        <version>1.1.1</version>

</dependency>

That's all on How to attain java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory Error, it may surface as "Exception inward thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory" too only mostly cause of both errors are same. If yous accept whatsoever other useful footstep to figure out ClassNotFoundException propose it here.
