Error in XMPP Sampler

[John No]

Hello!

Sorry, if I post this conversation incorrectly — it's my 1st try.

I've been trying to solve this issue during the last two days. I just wanna run test from JMeter 5.5 + XMPP Protocol Support 1.5.1. I did all correctly in accordance with The Ultimate Guide. I have also unsuccessfully tried a lot of solutions (e.g., described on Stack Overflow).

I've got the next info about this issue in jmeter.log:

What could be wrong?

Thanks in advance for all suggestions and I'll be grateful for any ideas for solving it.

[John No]

Sorry for not adding additional info — the problem is, my tests don't work properly in JMeter. In fact, they cannot be run at all.

[John No]

Could anybody tell me, how to build plugins from this URL? Do I need to build it separately (e.g., all in "xmpp" folder build as "xmpp.jar")? Or I need just build all files from URL, but in that case what name of this file should be?

Thanks in advance.

[Dmitri T]

You will need Apache Maven build tool in order to compile the project from source

The command to build only XMPP plugin would be something like:

mvn package -pl xmpp

it will create the .jar file under jmeter-bzm-plugins/xmpp/target/ folder.

However I don't think this is something you should be doing, you will get the same version as from JMeter Plugins Manager 

In order to troubleshoot your issue try increasing JMeter logging verbosity to DEBUG level for the XMPP components and the underlying Smack library, maybe you will be able to spot something there.

[John No]

Dmitri T, thank you for your response and the hint.

I've changed logging verbosity to DEBUG level and I've found some moments,  but I'm not sure what that actually means. I'm gonna add debug log info here, maybe someone has already ran into this issue.

Most interesting moments from debug log:

[Dmitri T]

I think this guy is pretty much self-explanatory:

2023-05-23 13:18:43,495 ERROR c.b.j.x.JMeterXMPPSampler: Please call Connect before calling other actions

so most probably you forgot to create the connection to your XMPP server, check out Understanding the bzm-XMPP Connection Config Element chapter.

[John No]

Yep, you're right about the line "2023-05-23 13:18:43,495 ERROR c.b.j.x.JMeterXMPPSampler: Please call Connect before calling other actions".

But unfortunately the reason should be somewhere else, because I added this connection before adding anything else:

To be honest, this is the first time I've asked questions on forums. I used to work as a web developer and I never had insurmountable problems. And now I don't even know how to find the cause of the error.

[John No]

And BTW, I'm trying just connect, login and disconnect. The same result I get in CLI mode.

[John No]

So, after I change Timeout to 0, my test starts working, but only with one error:
