NoClassDefFoundError org.eclipse.persistence.platform.database.oracle.Oracle12Platform

I got a 5-year-old Primefaces project. After much effort to recreate the environment, I am stuck with this error when logging in to the app.
java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.persistence.platform.database.oracle.Oracle12Platform.
Environment is Eclipse 2022-12, JDK8, Oracle XE 11.2.0.2.0, ojdbc8. Payara 5.2 multilingual server, Windows 10. The thing i am not sure about is whether the app uses EclipseLink or Hibernate since both are referenced in the project and i have multiple profiles for deployment (Payara, Wildfly) through Ant. Running on wildfly throws the same problem (different versions)
JDBC Connection pool and resources are configured in Payara. From the admin console, i can connect to the database successfully.
For clarity "PrijavaBean" in the log is the class handling the login (Croatian language)
The stack trace is:

ERROR: Caused by: org.hibernate.exception.SQLGrammarException: Error accessing table metadata MSSQL

The problem I have only occurs when i set the "hibernate.hbm2ddl.auto" to validate or update. When i try to create the Database it succeeds.
I'm trying to make a custom user FOO_Admin that can be used to run the program. After searching the web for a couple of hours, I think the problem is in the user that doesn't have enough rights? I've run the following sql snippet for my user/login:
USE FOO
CREATE LOGIN FOO_Admin WITH PASSWORD = 'MY_PASSWORD'
CREATE USER ADMIN FOR LOGIN FOO_Admin
EXEC sp_addrolemember db_owner, ADMIN;
EXEC sp_addrolemember db_datareader, ADMIN
EXEC sp_addrolemember db_datawriter, ADMIN
GO
USE MASTER
GO
GRANT CONNECT SQL TO FOO_Admin
Is there a way for me to grant rights to my user to get this working, or is there a different kind of error I'm not aware of?

Remote Mysql Access with Spring Configuration

I'm trying to connect my webapplication to remote db. My Spring configuration file is this:
<bean id="pwDataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://xxx.xxx.xxx.xxx:3306/my_databaseName" />
<property name="username" value="myUsername" />
<property name="password" value="myPassword" />
</bean>
but when i connect, i get a timeout error. I think it's probably a Mysql config error, so i have read a lot of examples on this site, but no one solve my problem.
I tried to create my_username and grant access to him, but mysql don't works.
mysql> GRANT ALL ON *.* TO 'myUsername'#'xxx.xxx.xxx.xxx' IDENTIFIED BY 'myPassword' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
but query not affected!!!
Also, I have modified /etc/mysql/my.cfg
bind-address = 0.0.0.0
P.S. When i use a mysql-client on web-application machine, I connect and use remote db without problem.
--EDIT--

Broken pipe with jpa 2.1, Hibernate 4.3.7 and C3P0

I have a problem of broken pipe in my software. I'm using Hibernate 4.3.7 and JPA 2.1 Final along with C3P0, I've tried everything, but still giving broken pipe when the time expires MySQL.
Logs from tomcat:
ERROR: The last packet successfully received from the server was 57,069,477 milliseconds ago. The last packet sent successfully to the server was 57,069,477 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

any idea?

1) There's a typo in your c3p0 config.
<property name="hibernate.c3p0.max_statement" value="50" />
should be
<property name="hibernate.c3p0.max_statements" value="50" />
2) In
<property name="hibernate.c3p0.preferredTestQuery" value="select 1;" />
...get rid of the semicolon. That is, just...
<property name="hibernate.c3p0.preferredTestQuery" value="select 1" />
3) These two properties are not valid c3p0 configuration:
<property name="hibernate.c3p0.interactive_timeout" value="10" />
<property name="hibernate.c3p0.connect_timeout" value="20" />
It looks like you are trying to set mysql server properties. interactive_timout is irrelevant; it is a config param for mysql command line tools. connect_timout (and wait_timeout) are system variables you can set on the server side
4) Verify that the config you want is the config c3p0 is actually seeing. c3p0 dumps its config at INFO on pool initialization. Look at that.
5) Assuming the configuration you intend has got through, you haven't quite got a reliable test regime configured. You are frequently testing idle Connections, but in theory a busy pool might never leave Connections idle for long enough to be tested. Given that MySQL is complaining about a disused rather than busy Connection, this is unlikely to be your problem. But still, it'd be good to impose a better testing regime, by, for example, setting testConnectionOnCheckin to true.
6) Once you get your config right, if you still see the error, the likely cause is that your application is holding onto Connections for long periods of time (e.g. as member variables) rather than checking them out as-necessary and close()ing them immediately. That's a bad idea. c3p0 can't help keep your Connections fresh if your application keeps them checked out, and the point of a Connection pool is to eliminate the performance cost of just-in-time Connection checkout. So, fix that.
If you aren't sure or don't think that any Connections are held open for long periods of time by your application, you can use the two settings unreturnedConnectionTimeout and debugUnreturnedConnectionStackTraces. The first will cause any Connections held open by your client application by more than the number of seconds configured to be forceably returned to the pool. The second will cause the stack trace of the code that checkout out the bad Connection to be dumped into log. See here.

org.hibernate.exception.JDBCConnectionException: could not execute query using hibernate

I've developed an application and it worked just fine locally , and when I uploaded it to a remote server it gave me com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException. I've tried the solution mentioned in the topic in this link :
https://stackoverflow.com/questions/7565143/com-mysql-jdbc-exceptions-jdbc4-mysqlnontransientconnectionexception-no-operati#=
here is the code that has access to database:
protected Number getCount(Class clazz){
Session currentSession = HibernateUtil.getSessionFactory().getCurrentSession();
Transaction transaction = currentSession.beginTransaction();
return (Number) currentSession.createCriteria(clazz).setProjection(Projections.rowCount()).uniqueResult();
}
and here is my hibernate configuration:
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/lyrics_db</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">123456</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.show_sql">true</property>
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<property name="c3p0.acquire_increment">1</property>
<property name="c3p0.idle_test_period">100</property>
<!-- seconds -->
<property name="c3p0.max_size">100</property>
<property name="c3p0.max_statements">0</property>
<property name="c3p0.min_size">10</property>
<property name="c3p0.timeout">1800</property>
<!-- seconds -->
</session-factory>
</hibernate-configuration>
and it's not working and I'm getting the same exception , and here is my full stack trace:

Does anyone know why this exception keeps happening even I changed my configuration?

I guess the problem was that I didn't commit the transaction , so it made some sort of lock.I figured this out from this topic:
What happens if you don't commit transaction in a database (say SQL Server)
