          Question:
          Deploying CEP through WARs on CentOS VM - Proton Server issue

          Description:
          I've deployed the 4 war files for Fiware Proton CEP, I got a month ago on githug (I believe), on a CentOS 6 VM, after installing Java SE 8 and Tomcat 7. These WAR files where inside a zip file, but now I can't find it on github anymore.

          Beyond that, following the instructions for instalation and configuration, I was able to get everything almost working.

          The Authoring Tool is available and working (it exports definitions to the server's repository correctly).
          Working with Google's Postman for http verbs i find that:

          A GET on the repositories works and retrieves the definitions exported by the Authoring tool: http://

          {ip}:8080/ProtonOnWebServerAdmin/resources/definitions
          But a GET on the server:
          http://{ip}

          :8080/ProtonOnWebServerAdmin/resources/instances/ProtonOnWebServer
          ...doesn't work and responds the following html message:

          So, I don't know what's wrong. It seems that it's some issue with Java configuration. I followed the installation instructions mentioned, so JAVA_HOME and CATALINA_HOME are set. I also set JDK_HOME to JAVA_HOME.
          Aparently ProtonServerAdmin works but ProtonServer itself doesn't, so I can't get CEP to really work.

          When I Reload the ProtonServer App from within Tomcat's Manager API, catalina.out logs the following:

          ..which doesn't seem to show any cautionary report.

          And when I perform a GET on the server, catalina.out logs just:

          ..so, no clues there.

          If you need more information please let me know.

          Thank you
