I have created a test plan in the JMeter GUI which uses the "Java Request Sampler".
I added the jarfile which contains the implementation to my sampler to /lib/ext/ of my jmeter installation.
This all works fine when I run it in GUI mode.
However when I switch to non gui mode using
./jmeter -n -t Test\ Plan.jmx
I get:
com.mycompany.JavaSamplerTest java.lang.ClassNotFoundException

I have no clue why this behaves differently when using -n -t. Does anybody have a solution to this?
I work on Linux using openjdk if this is somehow a helpful information.
Put the jar in jmeter/lib folder.
lib/ext is for real plugins.
