Re: Httpclient won't run in JUnit
Michael,
I confirm that the problem is perfectly reproducible with Sun JDK 1.2.2
(simple logger used per default) and Sun JDK 1.4.2 (JDK logger used per
default). However, what I discovered is that the problem occurred only
when using SwingUI. The same code runs without a hitch using TextUI.
I understand it's a small comfort to you, but the problem does not seem
to be caused by HttpClient. Try approaching JUnit people to see if they
know of any compatibility issues between JUnit's SwingUI and
commons-logging

I figured that since HttpClient uses JUnit for its test suite that
HttpClient had to be compatible with JUnit. Here's the most simple
JUnit example showing that the latest versions of HttpClient does not
run with JUnit. The example does nothing but start JUnit with the
latest versions of HttpClient and commons logging and no other
libraries involved:
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import junit.framework.*;
/**
* Simple example showing problem with running HttpClient code within
JUnit
*/
public class HttpClientJunitBug extends TestCase
{
public HttpClientJunitBug(String s)
{
super(s);
}
public void testSimple()
{
org.apache.commons.httpclient.HttpClient client = new
org.apache.commons.httpclient.HttpClient();
assertTrue( client != null );
}
}
prompt>javac HttpClientJunitBut.java
prompt>java -cp
junit.jar:commons-httpclient-2.0-rc2.jar:commons-logging-api.jar:.
junit.swingui.TestRunner HttpClientJunitBug
The result is:
java.lang.ExceptionInInitializerError
Caused by: org.apache.commons.logging.LogConfigurationException:
org.apache.commons.logging.LogConfigurationException: Class
org.apache.comons.logging.impl.Jdk14Logger does not implement Log
I thought maybe someone who runs the HttpClient test suite regularly
would be able to spot my mistake easily. (Hopefully!)

Re: Httpclient won't run in JUnit
Hi Michael, Looks like a class loader problem. My guess is that commons-logging is being loaded by more than one class loader.

HttpClient is supposed to work within JUnit since there's a test suite that uses JUnit. Unfortunately whenever I try to use HttpClient within JUnit, as in this one line instantiation: org.apache.commons.httpclient.HttpClient client = new org.apache.commons.httpclient.HttpClient(); what happens looks like a class loader error: java.lang.ExceptionInInitializerError Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.comons.logging.impl.Jdk14Logger does not implement Log It looks just like a class loader problem, but if HttpClient is tested from within JUnit there wouldn't be fundamental problems like this, so there's gotta be something wrong with what I'm doing. Note: I verified this with a couple of different JDK versions (1.4 and 1.5), on both Windows and OSX. (1.5 isn't available for OSX yet, and so that wasn't tested.) Thanks for any pointers-- I'd like to be able to use HttpClient.

Re: Httpclient won't run in JUnit
Michael, HttpClient is dependent on commons-logging library like many other Jakarta Commons components. You have to have commons-logging.jar on your classpath to be able to run HttpClient. You can obtain the commons-logging.jar at the following location: http://jakarta.apache.org/commons/logging.html This should help Oleg On Thu, 2004-01-29 at 22:43, Michael Czeiszperger wrote: > I apologize for asking a user-type question on the dev list, but the > common's user list was unable to help, and I've been working on this > for two weeks with no luck.
