Connecting java app to docker RTI

[rmpt]

Hi,
I'm trying to setup a java application to connect into the docker RTI, but the connection doesn't seem to work, even though I have the correct port mapping and the container running.

MAK RTI version: 4.6.1
Changed flag inside start.sh:
X=${MAK_RTI_RTIEXEC_PERFORMS_LICENSING:=0}: since we are using free version

All other flags are untouched.

I start the container with docker-compose up, everything seems fine, but then, when I run my app and calling the method:
rtiAmbassador.connect

I get the error:

Using MAK Technologies' RTI version 4.6.1 HLA 1516-2010 for Microsoft Visual C++ version 14.0 Release Mode.
Attempt to create and connect to Assistant
Create Process Failed with error (2)

Inside the container I get these logs, seems to be fine until trying to connect to RTI assistant:

I couldn't figure out how to connect into xserver, so I'm not sure I'm missing some popup, but since I've disabled licensing, I guess there's no warning about it.

Can someone help me here?

Thanks

What do you see on the X Display? Possibly the RTI Assistant is waiting for user input before it can continue.

Alternatively disable the RTI Assistant with RTI_ASSISTANT_DISABLE=1.
