Embedding ObjectDB on server application

I'm trying to integrate ObjectDB as part of a server software I am developing. I'm a little lost at the connection file path for the persistent factory.

Searching lists within objects

Hi everyone,  I've a problem with searching on lists. I'm uncertain as to what the best form is, so I've created a maven project with all the classes and a unit test showing my issue.

This does not help as I'm never going to have the real object at search time. ... ( ParentRunner. java : 236 ) at org. eclipse . jdt . internal . junit4 . runner . JUnit4TestReference . ...

Filename.odb$ Persisting Issue

Hi, I seem to have a frequent issue with my Filename.odb$ remaining in my /db directory after my program terminates which prevents me from running my program again due to a persistence error thrown by Eclipse. I can't seem to manually terminate the file either. I usually have to fully close Eclipse and wait a bit for it to remove itself. Any ideas why this happens?
