Start Play framework web service app from a Java application

I'm trying to start Play application (2.5 version) within a standalone Java app. The idea is to start an embedded web server that hosts the play based web service and then Java app will communicate with it. I found https://www.playframework.com/documentation/2.5.x/JavaEmbeddingPlay Is there any specific documentation on how to achieve this ?

Hi Nish,

The link you posted is the documentation on how to do this.  You'd want to instantiate a server, from the docs:

Server server = Server.forRouter(new RoutingDsl()
    .GET("/hello/:to").routeTo(to ->
        ok("Hello " + to)
    )
    .build(),
    Mode.DEV, 19000
);

The class is here: https://www.playframework.com/documentation/2.5.x/api/java/play/server/Server.html

Will.

Thank you . But I have already defined routes in my play app. why it is requried to define it again ?

You should specify the router you want -- if it's generated by Play automatically, it'll be in the /target/scala-2.11/routes/main/router/Routes.scala file.

Perfect . So then if I bundle the jar generated by sbt for Play app with my Java app , ideally it should solve my problem , isn't it ?
