Java Sampler help needed -- parameters don't show up
I have created a class that extends AbstractJavaSamplerClient. I
basically edited the JavaTest.class file included with the JMeter 2.3.1
source. I build the JAR file and put it in lib/ext. I'm using Java
1.6.0.03 on Ubuntu 7.10.
When I try to add a Java Sampler to a test, the first time I click on
the menu option, it does nothing. When I click a second time. I get a
sampler added. In the dropdown list, I can see my class, but no
parameters are listed (I have 2 defined in the getDefaultParameters()
method). When I select either the JavaTest or SleepTest options, they
don't show any parameters, either.
When I remove my JAR from the lib/ext directory and repeat the process,
the JavaTest and SleepTest options properly show parameters and the Java
Sampler is added on the first click.
Code is appended below.
Suggestions on where to look?
Thanks.

Re: Java Sampler help needed -- parameters don't show up
Posted by dennis <gz...@126.com>.
The reason why you cannot add Java Request Sampler is because you used
log4j in your code.
Actually, when you add Java Request sampler the first time, you can see
errors in the console. It says:
Exception in thread "AWT-EventQueue-0" java.lang.
e/log4j/Logger
at LaunchPLC.<clinit>(LaunchPLC.java:18)
You can add log4j.jar to JMeter classpath to solve this problem.
