Logging related problem with HttpClient

Hello,

I am having problems while using HttpClient. Here is a sample code :

package src.com.example.web;
// all necessary imports
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import org.apache.commons.httpclient.params.HttpMethodParams;


public class Sample {

	private static String url = "http://www.apache.org/";

	  public static void main(String[] args) {
	    // Create an instance of HttpClient.
	    HttpClient client = new HttpClient();

	  }
}

I have made sure that following jars are in the classpath :
commons-codec-1.3.jar
commons-logging-1.1.jar
commons-logging-adapters-1.1.jar
commons-logging-api-1.1.jar
junit-4.1.jar
commons-httpclient-3.0.1.jar

I am getting the following runtime error:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/commons/logging/LogFactory
	at org.apache.commons.httpclient.HttpClient.<clinit>(HttpClient.java:65)
	at src.com.example.web.Sample.main(Sample.java:12)

I have also tried using log4j but that didnot solve the problem. (As
an aside I am using Java 5.0 so I thing the logging facility provided
by java.util should be fine)

Any pointers regarding how to remove this error and get the code working?

Thanks in Advance
~Neelesh

Hi Neelesh/Ortwin,

While the library being used is HttpClient, the problem does seem to
really be a commons-logging(JCL)issue, and therefore belongs on this
list. I've changed the subject of this email to indicate this.

The httpclient 3.0.1 dependencies do specify commons-logging 1.0.3, but
the latest version (1.1) should be 100% backwards compatible while
having a lot less bugs, so logging 1.1 should be the right version to
use in this case.

In general, the commons-logging-api jar is intended only for use by
Apache Tomcat (and maybe other container frameworks). You might want to
use the full jar, or possibly the -adapters one if you're running this
code in a container that already deploys JCL.

>>From the exception stacktrace it looks like you're writing some sort of
webapp, running in some sort of container:
org/apache/commons/logging/LogFactory
org.apache.commons.httpclient.HttpClient.<clinit>(HttpClient.java:65)
src.com.example.web.Sample.main(Sample.java:12)

This page might be helpful:
  http://jakarta.apache.org/commons/logging/troubleshooting.html
If this doesn't solve your problem, then please post further details of
the environment you're actually running this code in.

Regards,

Simon

Neelesh,

Please see http://jakarta.apache.org/commons/httpclient/dependencies.html
for the correct version of the dependencies.

Note: HttpClient is no longer in Jakarta Commons. Our mailing lists are
these:

Cheers

Ortwin
