Hi,

Regarding java.lang.OutOfMemoryError, by default Java sets it MaxHeapSize size to about FreeMemory / 4, looks like this is not enough.
You can see the MaxHeapSize by running
java -XX:+PrintFlagsFinal -version | grep MaxHeapSize
And you can set it in JAVA_OPTS (for any java process)   or  SBT_OPTS  (just for sbt) environment variables, like this
export SBT_OPTS="-Xmx250m" (sets max heap 250MB)

This error was in sbt, so this means you are in development mode - compiling the application, you don't need sbt to run application in production mode (packaged by sbt stage/dist etc.)

Main configuration file is application.conf. 
application.ini is for options to packager (to staged directory, zip,deb,rpm). yes, it is confusing.

 commons.user is intended to have bigger than default limits for querying the commons via API, but not used yet, and can be just deleted or commented out (I already did it)

Database is initialised by https://flywaydb.org/ from sql scripts in conf/db/migration/default. 
On the first run in development mode the application will ask to run these. 

User is not created yet automatically, so you'll have to setup at least one by SQL, like this
INSERT INTO wlxjury.users (fullname, email, created_at, deleted_at, password, roles, contest, lang) VALUES ('Ilya (WLE Jury Admin)', 'intracer+2016@gmail.com', '2016-06-10 18:40:05', null, 'sha1 password hash', 'root', null, 'en'); 

Now I'm implementing the sign in feature, so this first user will be able to sign in himself :)

Regards,
Ilya

Hello Ilya

I have been working to install a local test instance of wlxjury. I more or less configured it (not all things are clear, and for greater confusion, there are two different configuration files: application.ini and application.conf), but it failed with an OutOfMemoryError at the first request (see log below). Any idea?

Regarding the configuration, what is the commons.user for?
Should the database be initialised in any way, or does it do it automatically?

Best
