Hi, I wasn't sure which forum to select, I hope this one fits?
I try to establish a database connection using JPA. My Bean's method looks like this:
Unfortunately it crashes somewhere in the code. I wasn't able to start TomEE in debug mode yet, so I can't step through it. Also I have no real logging yet, still trying to get all the foundation together. Anyone an idea what it could be? If I use only "Contact" instead of "sa.Contact" it doesn't make a difference...

Couldn't find one yet... As far as I know there is none in the server log. So I have to establish log4j first, than maybe I can see some exception logging...
Next thing is, that I wanted to debug using Eclipse, but I get a weird error message from the log / exception. I can post tomorrow, but google didn't help me yet...
Is there anyone who could imagine giving a hand in installation and configuration? I mean, I can't hire someone formally for a job as this is just hobby - ashame I am computer scientist myself, but the configuration really drives me nuts. So for a pocket money, some student who is deep in the topic anyway and could be happy to get some bucks this way...?

Ok, just one step down the line... Yes, I found an exception in the "localhost" log...
There is more, but I think that's clear... But therer IS a contact table...
Ok, german doesn't matter, I think anyone can see there is some sample data... Alright, this is my dependency injection for the entity manager:
This is the persistence.xml:
And then there is the tomee.xml which I think relates to the "samples" data source. But that's something I am really unsure about if my expectations are correct?
It could be missing rights (grants) to the table, or a schema mismatch. The table's schema is app, but the user is sa. Can you try explicitly setting the schema using @Table(name = "Contact", schema = "app") on the entity class?
