java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

Problem

Web application is deployed, but hits following error message.

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
	at org.apache.commons.httpclient.HttpClient.<clinit>(HttpClient.java:66)
	at com.mkyong.SimpleHttp.main(SimpleHttp.java:18)

Solution

This is caused by the missing of commons-logging-xxx.jar.

To fix it, download the commons logging library via http://commons.apache.org/downloads/download_logging.cgi, or Maven repository

<dependency>
	<groupId>commons-logging</groupId>
	<artifactId>commons-logging</artifactId>
	<version>1.1.1</version>
</dependency>

Then include it into your project classpath.
