Hazlecast Caching Problem #604
Description
Hi,
- today i tried to extend the application with hazlecast Caching System.
in app.java i extended:
use(new Hcast());
session(HcastSessionStore.class);
in the conf Directory i created hcast.conf
logging
hazelcast.logging.type = slf4j
session store, key prefix and timeout in seconds
hazelcast.session.name = sessions
hazelcast.session.timeout = ${session.timeout}
But when I start the application i get the following error
[2017-01-15 20:42:50,265]-[HotSwap] ERROR com.mycompany.App - An error occurred while starting the application:
com.google.inject.CreationException: Unable to create injector, see the following errors:

The Error relies on the "session" Statement but i have no clue what i made wrong.
2.) even when i remove the session command i noticed that every time i Change a bit of the Code a complete new instance of the hazlecast Server gets spinned and the old ones are still alive:
