Remote testing with Jmeter and loopback issue

Had some problem when I setup a remote testing environment with Jmeter. I used my own macine as master to aggregate the test results, and a couple of other machines as slaves. All machines was running Ubuntu.

The problem I had was that the log on the servers said:

jmeter.samplers.RemoteListenerWrapper: testStarted(host)
java.rmi.ConnectException: Connection refused to host: 127.0.1.1;

To fix this problem I had to changed the /etc/hosts on the master and comment out the loopback entry 127.0.1.1 and replace it with my permanent or real ip address.

127.0.0.1        localhost
192.168.x.x     nowwhat
#127.0.1.1      nowwhat

I also had to comment out the 127.0.1.1 hostname entry in the hosts file on all the slaves, but no need to add the real ip on them.

This problem only affected the machines that was running Ubuntu.

A note on JPA and embeddable

Took me a while to figure out that I have to place my embeddable element below the entity elements, got validation errors about missing embeddable element otherwise.

Simplified example

<entity class="example.Person>
  <attributes>
    <embedded name="name" />
    ...
</entity>
<embeddable class="example.Name">
...
</embeddable>
