Keep play application running after putty terminal closed

由 ￡可爱￡侵袭症＋ 提交于 2019-12-07 02:37:30
How to keep play application running after putty terminal closed? After deploying play application in to server, I ssh'ed into server with putty terminal and ran the play application. However, once I close the putty terminal, play application no longer accepts http requests from client. To start the play application I used following command; ./{myplayapp}/bin/{executable} -Dhttp.port=8000 use screen to start your application. view existing screens with "screen -ls" and switch between them with "screen -r" http://wiki.ubuntuusers.de/screen I would recommend nohup : nohup ./script -Dhttp.port

Scheduling/delaying of jobs/tasks in Play framework 2.x app

由 不羁岁月 提交于 2019-12-07 02:36:57
问题 In a typical web application, there are some things that I would prefer to run as delayed jobs/tasks . They tend to have some or all of the following properties: Takes a long time (anywhere from multiple seconds to multiple minutes to multiple hours). Occupy some resource heavily (CPU, network, disk, external API limits, etc.) Result not immediately necessary. Can complete HTTP response without it. OK (and possibly even preferable) to delay until later. Can be (and possibly preferable to) run

Play Framework: Handling dynamic created files (images) in PRODUCTION mode

由 一个人想着一个人 提交于 2019-12-06 11:59:09
I'm trying to allow users to upload photos to the server and then view them (all users can view all photos) in production (NOT development). While in development mode everything is simple - I can upload the files to the public folder and then read then from there, in production mode I don't have access to the public folder anymore (as this approach is for static accesses and not dynamic). So, I have 2 issues: Upload: currently I can't understand how to save the uploaded photos to a specific folder, without using an absolute path to the location where I want the photos to be saved. Here is the

Play 2.3 requireJs optimization and shim for multiple modules

由 依然范特西╮ 提交于 2019-12-05 12:40:59
This is my current setup for Play 2.2.x requireJS. Will it continue to work after 2.3? I can't find requireJs or requireJsShim anywhere in the 2.3 documentation. requireJs ++= Seq("mainAccount.js", "mainOrg.js", "mainPublic.js"), // This tells Play to optimize this file and its dependencies requireJsShim += "build.js", // This tells Play to read the RequireJS "shim" configuration from build.js requireJsFolder := "js" Instead of requireJs use: RjsKeys.modules := Seq( WebJs.JS.Object("name" -> "mainAccount"), WebJs.JS.Object("name" -> "mainOrg"), WebJs.JS.Object("name" -> "mainPublic") ) Instead

NOTE: The reason to make images served using Assets is because of
