| Re: [glassfish-dev] How to use Glassfish with MySQL or any database instead of Apache Derby |
Why is the data source not bound to jndi and why isn't a proper error logged when the data source has trouble deploying? Sounds like someone needs to explain or dig into the code to improve. I have helped a lot to run TCK tests against glass fish and problems like this should be fixed by those with the itch to fix when they happen.Maybe ask how one would try to find and improve the code responsible for data source deployment.Just my two dollars of thoughts on this. Sorry about the spell checker on my phone changing technical terms to be spelled wrong :)Scott_______________________________________________On Fri, Apr 26, 2024, 10:42 AM Victor Gimenez via glassfish-dev <glassfish-dev@xxxxxxxxxxx> wrote:Em 2024-04-26 10:29, Victor Gimenez via glassfish-dev escreveu:

I did another test to verify taking all the <persistence-unit
name="MySqlUnit"> XML block on persistence.xml and I received another
message:
```
Error occurred during deployment: Exception while preparing the app :

persistence-context-ref-name [dukes.greeting.GreetingRepository/em] in
the scope of the module called [challenge2]. Please verify your
