COMP 353
Summer 2015-16
Installing Play 2.0
 https://www.playframework.com/documentation/2.0.x/
Installing
 Prerequisites: JDK 6 or 7
 download and install the JDK package
 Be sure to have the java and javac commands in the
current path (you can check this by typing java version and javac -version at the shell prompt)
 Download the Play 2.0 and extract the archive to a
location where you have both read and write access
 http://download.playframework.org/releases/
 Add the play script to your PATH
 Check that the play command is available
 play help
 Install sbt
 http://www.scala-sbt.org/release/tutorial/Installing-sbton-Windows.html
Creating a new application
 play new myFirstApp
 This will ask for some information.
 The application name (just for display, this name will
be used later in several messages).
 The template to use for this application. You can
choose either a default Scala application, a default
Java application, or an empty application.
Setting up your preferred IDE
 Working with Play is easy. You don’t even need a
sophisticated IDE, because Play compiles and
refreshes the modifications you make to your source
files automatically, so you can easily work using a
simple text editor.
 However, using a modern Java or Scala IDE provides
cool productivity features like auto-completion, onthe-fly compilation, assisted refactoring and
debugging.
Eclipse
 Play provides a command to simplify Eclipse
configuration. To transform a Play application into a
working Eclipse project, use the eclipsify command:
 without the source jars:
 [My first application] $ eclipsify
 if you want to grab the available source jars (this will
take longer and it’s possible a few sources might be
missing):
 [My first application] $ eclipsify with-source=true
 You then need to import the application into your
Workspace with the File/Import/General/Existing
project… menu
 Go to your application folder
 Play debug (9999)
 Eclipse: Right click on application folder Debug
asDebug ConfigurationsRemote Java Application
 Host: localhost
 Port: 9999
 Connection type: standard (socket attach)
 run (in terminal)
 Eclipse
 Add a breakpoint
 Go to localhost:9000
