eclipse - JPA entities from tables, no schemas listed

Question

I have a database (called "socializer") residing within MariaDB server and I'm trying to generate JPA entities from tables of that database in Eclipse, but cannot, because schema selection is grayed . Any ideas why?

My setup: Eclipse Neon, Eclipse Link 2.5.2, MariaDB 10.1.19-1, Arch Linux.

I know that the connection to my database has been established, because I can see it listed in Data Source Explorer , but its "Schemas" folder is displayed just empty, although it actually contains a few tables, created and perfectly observed within MySQL Workbench (the other listed databases appear to have empty "Schemas" as well).

JDBC connection properties:

Database: "socializer"
URL: "jdbc:mariadb://localhost:3306/socializer"
User name: root
Password: ""

JDBC driver (Generic JDBC Driver, mariadb-java-client-1.5.5.jar) properties:

Connection URL: "jdbc:mariadb://localhost:3306/socializer"
Database Name: "socializer"
Driver Class: "org.mariadb.jdbc.Driver"
User ID: "root"

And yes, user name and password are ok (ping will fail if either of them is changed).

Answer 1

In Addition to the comments, I found another reason that might cause the problem, that no schema's are listed:

I run into this while trying to connect to another database with other schemas than before.

Go to Project -> Properties -> JPA and disable/uncheck Override default schema from connection

If there is a schema selected that doesn't exist in the selected database, no schemas will be shown when creating entities. For me the problem was, that Eclipse was trying to show a schema from the database before.

This Worked For me.... Go to Go to Project -> Properties -> JPA

check both checkboxes

1. override default catlog from connection --> select ur connection
2. check default schema for connnection --> select ur schema

and done.. :)

Answer 5

In my case, I'm connecting to MySQL, and the problem is I need to add JDBC driver to Eclipse.

Then when Eclipse asks you to select a connection profile, select the driver you added (MySQL for me, instead of Generic JDBC), and you should be able to see all schemas.
