Unable to access mysql from jpa after Catalina update

My jpa application was working fine (in fact, my 2 jpa applications) since I update my mac to Catalina (and restart it, of course).
Since then I got
org.hibernate.engine.jdbc.env.internal.JdbcEnvironmentInitiator initiateService
WARN: HHH000342: Could not obtain connection to query metadata : null
Exception in thread "main" org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]
...
Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
But from mySQL Workbench I can access my databases with no problem.
I've tried to reinstall mysql, even using brew to do it. Nothing works.
I changed nothing on my persistence.xml file nor my code.

My mysql version is 8.0.19.
Thank you!
Next day update (28/4):
By now, I have:
1) Added this line to my persistence.xml:
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
As I got a new error...
Access denied for user 'root'#'localhost' (using password: YES)
2) Followed this instructions to set root password:
https://medium.com/#aungzanbaw/how-to-reset-root-user-password-in-mysql-8-0-a5c328d098a8
Now my new error is
Connection refused
Next next day update (29/4):
Today I stoped and started mysql from terminal:
sudo /usr/local/bin/mysql.server stop
sudo /usr/local/bin/mysql.server start
I then I got a new error
The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specifc time zone value if you want to utilize time zone support.
Let's continue my investigation!
Following this question: https://es.stackoverflow.com/questions/48935/configurar-zona-horaria-jdbc-driver-java/48946?newreg=494e1840d4404575a81dc4ec10200266
I modified persistence.xml:
So I got a
Table 'myschema.mytable' doesn't exist
error.
Finally I got it, not sure how... probably restarting from comand line.
Here my final persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>

Using MySQL8Dialect is necessary to be able to create the tables without that error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'type=MyISAM' at line 1

Mysql Driver class com.mysql.jdbc.Driver is not a valid javax.sql.DataSource implementation from wildfly

maybe my setup is quite special, but I do have issues when I define a JDBC Datasource for Java EE container in my web.xml file.
I configured my Datasource in my web.xml as follow:
<data-source>
<name>java:app/myapp/DS</name>
<class-name>com.mysql.jdbc.Driver</class-name>
<url>jdbc:mysql://localhost:3306/database?useSSL=false&allowPublicKeyRetrieval=true</url>
<user>foo</user>
<password>pass</password>
<transactional>true</transactional>
<isolation-level>TRANSACTION_READ_COMMITTED</isolation-level>
<initial-pool-size>2</initial-pool-size>
<max-pool-size>10</max-pool-size>
<min-pool-size>5</min-pool-size>
<max-statements>0</max-statements>
</data-source>
After I use datasource's name as my jta-data-source in my persistence file as follow:
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<property name="javax.persistence.schema-generation.database.action" value="none"/>
<property name="javax.persistence.schema-generation.scripts.action" value="none"/>
</properties>
</persistence-unit>
</persistence>
And in my code I used the EntityManager to make request to the database.
But when I deploy it to wildfly 18.0.1, I get the following errors:

I think that if I replace com.mysql.jdbc.Driver with com.mysql.jc.jdbc.Driver, it will deploy successfully but I still have the same problem and the same message error.
I don't know if I miss something on how to define a mysql JDBC datasource in web.xml file. but I think it is correct.
Please can someone help me.

Guide me where is the problem. There is issue regarding connector version or MySQL version mismatch??
What IDE are you using? Try and add it to your classpath there and then deploy.
If it is a web app try putting to WEB-INF/lib
If it is maven app put the snippet inside your pom.xml
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.34</version>

JBOSS 7 MYSQL missing dependencies error

There are many threads like this one already for similar errors but none which have solved my problem so after an hour of trying to debug it, I have decide to ask for help.
Background
I am setting up a Java EE project. I have create an enterprise application and have create an EJB project, JPA project and web Project and added EAR's to the enterprise project.
I have also added mysql-connector-java-5.1.0-bin to the JBOSS/standalone/deployments folder. And added to this jar file to the JPA project.
Any advice on how to solve the error would be greatly apprecited.
The main error is:
missing/unavailable dependencies" =>

You need to create MySQL driver module.
JBoss 7 will be able to use if you create it like this:
download the driver (jar file)
create directory in you server path: {$jboss-home}/modules/com/mysql/main
and paste the driver jar file here
in same folder create and new file module.xml
Insert following code in that module.xml (if your jar file is named mysql.jdbc.jar):
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.mysql">
<resources>
<resource-root path="mysql.jdbc.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
Make sure the dependencies for your mysql.jdbc.jar are OK.
JBoss 7 is not using -ds.xml any more.
You allready doing setup for your databse in standalon.xml, this the right way.
Just make sure your migration is correct. I see you have diffent user name and password...
EDIT1:
I don't know how hibernate works with JBoss 7.
But I see you should try to change in your persistence.xml
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
to
<property name="hibernate.connection.driver_class" value="com.mysql"/>
because you are using com.mysql as module name. Otherwise you can change module name to com.mysql.jdbc.Driver.
In your standalone.xml
change
<driver>mysql-connector-java-5.1.0-bin.jar</driver>
to
<driver>com.mysql</driver>
because you gave com.mysql as name for your driver:
<driver name="com.mysql" module="com.mysql">

Can't find mysql.jdbc.Driver - MySQL, JBoss

I'm unable to deploy my web app with MySQL 5.5.11 backend to JBoss 5. I get this error:
Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver from BaseClassLoader#262b2310
I pasted my stack trace below.
Here's what I've done...
I added mysql-connector-java-5.1.14-bin.jar to {JBOSS_HOME}/lib (that connector should work with MySQL 5.5.11 right?). I also added mysql-ds.xml to {JBOSS_HOME}/server/default/deploy.
<datasources>
<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/my_libl_db</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>

<password>test</password>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
</local-tx-datasource>
</datasources>
Also, I made sure the mysql-connector-java-5.1.14-bin.jar in my lib folder is in my web apps classpath. In the JBoss Admin Console, under Resources/Datasources, I do see MySqlDS with a status of up.
My project (in Eclipse Indego Release) is an Enterprise Application Project with 1 Dynamic Web Project. The web app has has an #Entity bean and a #Stateless bean. The #Stateless is being injected to a servlet (using #EJB). Here's my persistence.xml:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">

<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>

What could I be doing wrong?

This bit of documentation says you need to add the JAR to the /lib file in your default server configuration:

UPDATE: JBOSS 6 and newer has been rewritten to be more modular. You have to add JBDC drivers to your /module directory.
