deploying Grails app in Heroku

[Sherif Shehab]

Hi all , 

I'm trying to deploy Grails application to Heroku, and it's successfully deployed ,  here is the log :

|Done creating WAR target/PatientBoards-0.1.war
 -----> No server directory found. Adding webapp-runner 7.0.57.2 automatically.
-----> Discovering process types
   Procfile declares types     -> (none)
   Default types for buildpack -> web
-----> Compressing... done, 132.4MB
-----> Launching... done, v5
   https://patientboards.herokuapp.com/ deployed to Heroku

But when I go to https://patientboards.herokuapp.com the page is blank !

Am I missing something ?

Thanks

Sherif

Try running "heroku logs --tail"

When you first access the heroku app it can take 30-40 seconds to start the grails application, and the first call can cause an error.

Tailing the logs should let you see if anything is happening and if there are any errors.

I have successfully run grails.2.4 apps on heroku using the grails wrapper.

Hi,
the problem in the Stacktrace seems that a cache plugin (enabled by default ?) is trying to read something from the disk, but Heroku hosted webapps doesn't publish a file system to read ... sorry.

Your webapp is based on Grails 2.x or 3.x ?
For Grails 3 you can try my sample (is fork on a recommended version by Heroku support) for Grails 3.0.x and Heroku, sources are here:

https://github.com/smartiniOnGitHub/grails3-example

I still have to make some update there to show how to make a MongoDB connection work, I'll do it when possible.
Remember to use latest 3.0.x for your tests.


The running version (usually put in sleep mode, but awaken when someone ask for it) is here:

http://grails3-example.herokuapp.com/


Hope it helps.

Bye,
Sandro
