Question about transfer-03-consumer-pull. [A binding for port 19291 already exists]

[lesile231]

Hi. Thanks to your help, I was able to get to this stage. Thank you.

However, I'm getting an error when running the source code without any modifications. From what I can see, it seems the error occurs when trying to use port 19291 again while executing the jar.

Thank you for your help!!

maybe you have the provider from transfer-02 still running, and it conflicts with it, eventually just stop it, and everything should work fine

[simon-dengler]

I'm having the same problem and tried to change the port in the provider.properties, just in case anything is left running. But I still get the same error as before.

[ndr-brt]

the A binding for port 19291 already exists means that there's another process running in your machine listening on the port 19291. On linux you can use the lsof command to check that: lsof -n -i :19291

[lesile231]

Yeah, I totally understand about that error, too.

When I run a provider from another example that users the same port (19291), there's no issue, which indicates that port 19291 is currently not in use. So this suggests that ports are being overlapped during startup in the "transfer-03-consumer-pull" case. I've tested to change a value "web.http.public.port=19291" to "web.http.public.port=19296" in the "transfer/transfer-03-consumer-pull/resources/configuration/provider.properties", which makes just "A binding for port 19291 already exists" error message to "A binding for port 19296 already exists". It absolutely occurs in the example.

I tried run this example with removing the portMappingRegistry.register part in the initialize function of CustomProxyPlaneExtension.java file. Then, the port overlap issue disappeared, although it is not working well for other problem.

I didn't any change to code and properties files.
Could you tell me if there are any specific settings I need to configure for this part?

Thank you!

I guess the sample it is not working properly, could you please open an issue in regard? contributions in form of pull requests are welcome as well

[lesile231]

Okay, Thank you for taking the time to respond!
