my application works fine on my local installation in Netbeans 11 (the Database (MariaDB) is running on an external ubuntuserver). When I deploy the application on my ubuntuserver (glassfishserver) the LoginPage becomes visible, but when I want to login (so when entities are needet and I need a connection to the database) I get this errormessage:
/index.xhtml @29,141 value="#{userLoggedin.username}": Target Unreachable, identifier 'userLoggedin' resolved to null
The database can be reached from the ubuntuserver where I deploy my application (there is a pretty small Java app running on the glassfishserver with "prepared statements" -> and this works fine with the database).
The application is written in Java - JSF.

So once more: the software works really fine on my local computer but not when I try to login on the deloyed one. I hope someone can help me ...
