[Torjmen (Torjmen Med Amine)]

hello , i'm trying to create a plugin for openEdge form SonarQube API ,
its' work well .
I have programmes written in progress 4gl , for that i had created an AppServer using the Openedge explorer to put my programmes.p (progress 4gl ) in it .
i have a code to run programmes in progress openEdge using java
