Why we need implicit Application
It's an architectural choice that was made by the developers. There are certain components of the framework that require a reference to an Application (typically the current running Application). The Cache, DB, Messages (i18n), Evolutions, and WS API are the first ones that come to mind. The Application trait is...
Suddenly unresolved dependency echo-trace-play echo-sigar-libs
java,playframework-2.0,sbt,typesafe-activator,typesafe
Solved. I had to do a git checkout on the "project/play-fork-run.sbt" file on so it could return the line below to 2.3.8 version: addSbtPlugin("com.typesafe.play" % "sbt-fork-run-plugin" % "2.3.9") After that I reseted the "activator ui" command. It ran the whole upgrade to 2.3.9 again and now it worked. Probably some...

How to chunk responses in Play without running out of memory
playframework,playframework-2.0,playframework-2.3
Unfortunately this is a limitation of Play's Java API in Play at the moment. There is no way in the Java API to get back pressure from the client, so it's easy to overwhelm the client. This will be fixed in Play 3 when we provide a better streams API...

Implicit conversion not taking place for Play Framework Lang in controller
scala,playframework,playframework-2.0
According to Play documentation If you have an implicit Request in the scope, it will provide an implicit Lang value corresponding to the preferred language extracted from the Accept-Language header and matching one of the application supported languages. So you need to change your action to def createView = Action...
Dependent futures
scala,playframework-2.0,future
You are missing two Future concepts in your solution: flatMap and Future.sequence To explain each: flatMap is like map except instead of giving it a function from future.map(A => B) you give it a function from future.flatMap(A => Future[B]). This way you can chain Futures together. Future.sequence is a helper...
Play Scala activator compile command shows value userid is not a member of play.api.data.Form[models.Changepas sword]
scala,model-view-controller,playframework,playframework-2.0,typesafe-activator
You can't use the value of the form as a parameter for the route: @form(routes.Users.updatePassword(userForm.userid.get)) The userid depends on the form and could therefore change. In any case, you would access the userid of the form using userForm("userid") and not userForm.userid (although it might not be what you want/need). A...
Java / Ebean And Or Query

Scala Play Forms verify that one date occurs after another
scala,playframework-2.0,playframework-2.3
You can't reference other form fields within the same mapping until after they all successfully bind individually. That is, the constraint must be made on the outer mapping. val policyForm: Form[PolicyForm] = Form { mapping( "amount" -> of[Double].verifying(...), "beginDate" -> date("yyyy-MM-dd").verifying(...), "endDate" -> date("yyyy-MM-dd") )(PolicyForm.apply _)(PolicyForm.unapply _).verifying("End date has be...

Trouble understanding WS library in Scala
It appears that you are calling WS inside the map block of collection.insert. That map expects that you return a play.api.mvc.Result, however WS.post with the map you have attached to it, returns a Future[play.api.mvc.Result]. Given that the Future.successful(BadRequest(Json.obj("message"->"Invalid email address"))) returns Future[play.api.mvc.Result] and your collection.insert returns a Future[Future[play.api.mvc.Result]] the common,...

Great question - I was in the same boat as you! I'd have just the DAO and this code: TableQuery[UsersTable].schema.create which'll create the database table for you. No need for the .sql. Correspondingly, to drop, use .drop instead of .create. You can also combine table creation of several tables using...

Looks close. Change val to var because it is not final and needs to be injected at a latter stage. @Inject var mailer: MailerClient = null I'd check also that the MailerClient library is mentioned as a dependency in the project configuration. You could try with WSClient instead as it's...
Return type of bindFromRequest.fold
as m-z said in the comments, change val t = rqForm.bindFromRequest.fold( formWithErrors => BadRequest("That's not good"), rq => Ok((views.html.properForm("POST tweets TBD.")(Html("<em>Blah</em>")))) ) // expect a play.api.mvc.Result println(t.getClass.getName) // this confirms it in both run-time cases t match { case v:Result => v } // yet this is required for compile...
Setting up play framework and dart for development and debug
eclipse,playframework-2.0,dart,dart-pub,typesafe-activator
I guess the best way is to use a proxy with rules to forward requests for Dart resources to pub serve and play resources to activator. This would be simple to build in Dart for example using shelf, shelf_route and shelf_proxy or nginx with a few forwarding rules.
Generating a link to a controller action in Play Framework 2.3
The problem seems to be not the @routes syntax (which you have completely correct) but rather a case of the Twirl engine not seeing where code ends and HTML begins (or something like that anyway...) The line you've included, which has both a var and a semicolon, made me suspect...
Activator throws IllegalArgumentException: URI has an authority component
playframework-2.0,sbt,typesafe-activator,activator
What caused this? Still no clue. But just deleting the .sbt folder in the root directory made sbt refresh everything from scratch. All projects now work properly again.
Play Action Async wrapping a Future
scala,asynchronous,playframework-2.0
Action.async is not enough to make your code asynchronous. Here is the signature for async (I picked the simplest overload): def async(block: => Future[Result]): Action[AnyContent] It's up to you to provide that Future. If you're calling blocking code you can execute it concurrently like Future { blockingCode() }. However the...
Play! framework Java Promise example
java,playframework-2.0,promise,java-7
From play documentation: Maps this promise to a promise of type B. The function function is applied as soon as the promise is redeemed. The function: new Function<Double,Result>() { public Result apply(Double pi) { return ok("PI value computed: " + pi); } } will convert the pi value of type...
Accessing h2-browser and debugging in play framework application
When you start the console with h2-browser command then it runs until you exit from activator. Like this: activator -jvm-debug 9999 h2-browser run ...

How to serve reactive ByteChunks in Play Framework (Java) v2.4.x
java,playframework,playframework-2.0,reactive-programming
Your getContentLength method is incorrect, because it returns negative lengths: MP3 size = 12000 from = 0 to = 5000 getContentLength = -4999 Fix this method and it should work. Apart from that, you should note that range and chunks are static fields, and you may face concurrency problems. Also...
How to mock an Authenticator in play framework with guice injections?
java,playframework,playframework-2.0,guice,guice-3
A found a workaround. I just used an access method provided by Play framework 2.4 since it fully integrates Guice. Here is my Authentication Wrapper class: public class AuthenticatorWrapper extends Security.Authenticator { private final Security.Authenticator authenticator; public AuthenticatorWrapper() { authenticator = Play.application().injector().instanceOf(Security.Authenticator.class); } @Override public String getUsername(Http.Context ctx) { return...
Play 2: How can I get an URL with parameters that aren't encoded when reverse routing?
routing,playframework-2.0,url-encoding
I wouldn't do it - slash has its usage even in the param, therefore it SHOULD be encoded. Also for security reasons that isn't best option. On the other hand, in Play you have other possibilities to pass the return URL, my favorite are Flash/Session scopes and/or in mem Cache...
Interchangeable menu in Scala Play
scala,playframework,playframework-2.0
If you're applying loginMenu as an argument to main you don't need the @ in front of it, since you're already in a Scala code block. Try: @main("Welcome to Play", "Home")(loginMenu()) { <div class="container"> <h2>Home</h2> </div> } ...
where is this 'helper' imported from in Play Framework
If you look at Rendering an <input> element section in the documentation, you'll find out that all helpers are placed at the views.html.helper package. Since the view you mentioned is located in the views.html package the import can be relatively shorter.
