java.lang.Throwable: Could not access /usr/share/jmeter/lib/junit

Do you have a sample test plan which I can use to reproduce the problem?

Apparently some files required by junit module were not part of the upstream distribution. They have been checked in recently in upstream SVN. I will need to backport them as patch.

The upstream svn change is http://svn.apache.org/viewvc?view=revision&revision=817394

This error occurs for every jmeter test case I've tried.

While the missing directory error is always there, it surely doesn't affect every testcase. I just tried HTTP sampling (www.google.com) and it works without problem.

I suppose the problem is seen only when running junit sampling. Can you please confirm and if possible add a sample .jmx file?

On further analysis i found out that the files missing are just dummy test cases. They are not referred from junit module and hence should not cause any problem in functionality.

Sorry, I'm away from my computer, so I can't upload the exact jmeter test. But, it was very simple: it only had one HTTPClient Sampler (perhaps that's the trouble maker?) and a Aggregate Report listener.

There was indeed a problem with HTTP Sampler. That bug is bug #457660. Are you talking about same?

The problem is your bug report is not very clear about what exactly the problem is. The warnings you see on the console are fine as long as they do not affect functionality.

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:

"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.

Simple jmeter test that demonstrates the issue

Thanks for the sample test case.
The problem is that even though libcommons-httpclient-java depends on libcommons-codec-java, it does not add commons-codec.jar in classpath (usually done in MANIFEST.MF file). At the same time jmeter launcher script does not explicitly add commons-codec.jar in classpath. So even though the library is available you get class not found exception.

I will fix this soonish.

This also needs fixing in libcommons-httpclient-java so other packages which depends on it don't face this problem.
