Kurento media server - unable to run hello world tutorial

[KP]

I want to use KMS on my project, so I started reading about it and I want to run hello world from tutorial.

In tutorial I've read I have to use Ubuntu 14.04 LTS. So i downloadd it and tun it in VirtualBox, after that I've installed KMS on my machine and tried to run first example.

Firstly I have some problems with mvn - but I found in google I should use mvn3.

After that I started with this commands from tutorial

git clone https://github.com/Kurento/kurento-tutorial-java.git

cd kurento-tutorial-java/kurento-hello-world

git checkout 6.6.0

mvn compile exec:java

and I have this result

ted by vagrant in /vagrant/kurento-tutorial-java/kurento-hello-world)

I was trying to solve it, but even if I solved something there are another problem.

So - is there any stable version? Or vagrant box/image of VM which is configured for running Kurento?

[Micael Gallego]

Kurento Media Server is stable. There are a lot of users using it. 

There is no "official" vagrant image for Kurento. But there is an official docker image that can be executed with this command:

$ docker run --name kms -p 8888:8888 -d
kurento/kurento-media-server:6.6.0

And the Java application can be executed in the host machine regarding its operating system.

You can also try OpenVidu, a new and easier way to develop Kurento applications. We are working right now in the documentation, but you can start executing the examples:
