How to deploy play framework 2.4 application on glassfish and read application.conf?

Same question is at stackoverflow : http://stackoverflow.com/questions/34738905/how-to-deploy-play-framework-2-4-application-on-glassfish-and-read-application-c

I tried to deploy play framework 2.4 application on glassfish4. I used maven play2 plugin and play2 war plugin made war file with the following instruction.

https://play2-maven-plugin.github.io/play2-maven-plugin/1.0.0-beta4/war-packaging.html

After that, I tried to deploy my war from glassfish console, but it returned the following error.

Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: 
ContainerBase.addChild: start: org.apache.catalina.LifecycleException: com.google.inject.CreationException: 
Unable to create injector, see the following errors:

The following is the part of full log.

3) Error in custom provider, java.lang.NullPointerException

My conf/application.conf is here:

db.default.driver=oracle.jdbc.driver.OracleDriver
db.default.url="jdbc:oracle:thin:@url..."
db.default.username=username
db.default.password=password

It works on local environment. I think glassfish can't read application.conf in war file.

Could you give me the advice?
