NPE When Attempting to Add an Entity Class from the Database

SeanCarrick commented 6 months ago

Apache NetBeans version

Apache NetBeans 21

What happened

Created a database on the Services tab of the IDE, using Apache Derby 10.17.1.0, then tried to add an entity class from the database in my project from the Projects tab. The New Entity Classes from Database dialog opened, but had the message "Please wait..." with a radio button, but never did populate the combo box with the databases from my Derby server. When I selected the Local Data Source radio button, the combo box stayed empty, without even the option to select a database:

Language / Project Type / NetBeans Component

Standard Java (JDK21) Application project using Ant

How to reproduce

Configure the Services...Java DB node with Apache Derby 10.17.1.0 for the server
Start the database server
Create a database, or use the sample database
Create a standard Java application project from the Projects tab
Add an Entity Class from Database to the project

Did this work correctly in an earlier version?

Apache NetBeans 19

Anything else

This is the first time that I have seen this issue. However, I have not attempted to add entity classes from a database since at least NB19. I used to use this feature a lot back in the good old days of JDK8/NB8.2.

Are you willing to submit a pull request?

No
