java.lang.NoClassDefFoundError: org/apache/commons/httpclient/Credentials error

Question

I have started fitnesse rest api testing. I am only 3 days old to it. I am able to run on localhost 80. But it showed few error to me, there were few jar files missing.

I am still getting below error.

List of jar I have added:

httpclient-4.0.jar
log4j-1.2.16.jar
slf4j-api-1.7.12.jar
slf4j-simple-1.7.12.jar
smartrics-RestClient-2.1.jar
xstream-1.4.8.jar
xuggle-xuggler-5.4.jar

I am not using any IDE. I open `fitnesse-standalone.jar` in `cmd`. It gives `fitnesse` front page on `localhost`, from there I click `Test` and tests runs. — paul, Jun 28 '15 at 07:52

RestFixture depends - for it's HTTP interactions with the System under test - on RestClient (https://github.com/smartrics/RestClient), which in turns depends on Apache HTTP Client 3.1 (http://hc.apache.org/httpclient-3.x/).

The exception you see is caused by having added to your classpath "httpclient-4.0.jar" (which doesn't contain the missing class).

You can fix the problem (and avoid any other class not found issue) by adding all jars provided in the RestFixture bundle smartrics-RestFixture-4.0-bin.zip for example available from http://repo1.maven.org/maven2/smartrics/restfixture/smartrics-RestFixture/4.0/
