Comment 9 for bug 459251

My apologies - by bug report does suck. I swear - I don't normally make such horrifically vague and uninformative bug reports!

When using the "HTTP Request Sampler," jmeter seems to work correctly.

When using the "HTTP Request HTTPClient Sampler," I get the attached output in jmeter.log. IMHO, the most interesting part of the log is this:

"ERROR - jmeter.threads.JMeterThread: Test failed! java.lang.NoClassDefFoundError: org/apache/commons/codec/DecoderException

"org.apache.commons.codec.DecoderException" can be found in Apache Commons Codec, which is Ubuntu's libcommons-codec-java, which I do have installed. In /usr/share/java/commons-codec-1.3.jar, org.apache.commons.codec.DecoderException is defined... so I don't know why jmeter is unable to find it.
