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">
<persistence-unit name="java-rs-with-hibernate" transaction-type="JTA">
<jta-data-source>java:app/myapp/DS</jta-data-source>
<class>com.patrickhub.ch.java_rs_with_hibernate.domain.Product</class>
<properties>
<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.

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

Finally I got it, not sure how... probably restarting from comand line.

Using MySQL8Dialect is necessary to be able to create the tables without that error:

I have a REST service which access a MySQL database. I'm using Wildfly 10 and MySQL 5.7.12. I am trying to get the EntityManager as an injection and I get the following error when executing the find method for my Entity mapping the table content.

The issue is that if instead of using injection I retrieve the entity manager using the manual way everything works smothly.
EntityManagerFactory emFactory;
emFactory = Persistence.createEntityManagerFactory("myUnit");
EntityManager em = emFactory.createEntityManager();
Could you give me some hints on how to use the PersistenceContext? the code is somehow cleaner and I prefer to use it.
It looks like you 're getting the default datasource injected in your persistence Unit so I guess this depends on how the EntityManager is 'built'. One way to fix this is to create a datasource in WidFly and use it (through) its JNDI name in your persistence unit.
Feel free to report a bug http://issues.jboss.org/
You are setting up a RESOURCE_LOCAL persistence unit. You should configure it as such:
<persistence-unit transaction-type="RESOURCE_LOCAL">
In order to use a resource local persistence unit you cannot inject EntityManager, only EntityManagerFactory. You'll end up with a lot less plumbing if you switch to JTA datasource and let the server manage it.
If you absolutely don't want to edit standalone.xml, in WF8 anyway, you can drop yourdatasource-ds.xml file into your WEB-INF folder, or into the deployments directory alongside your .war file. There was talk of removing this from WF though so I don't know if it works in 10.x.
On work, im using Eclipse, Jboss and Hibernate JPA. For a smaller, private project I like to use Netbeans, GlassFish and Hibernate JPA.
Problem: I want hibernate to generate the tables automagically - but it won't do that for me.
What i did:
First, i installed - obvious is obvious - Netbeans, Glassfish and a local MySQL-DB.
I created a JDBC-Connection for Glassfish:
url: jdbc:mysql://localhost:3306/myDatabase?zeroDateTimeBehavior=convertToNull
name: myDatabaseJDBC
Driver: com.mysql.jdbc.Driver
The connection seems fine, "testing" it resolved to a successful connection.
Now i created the persistance.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="primary" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>myDatabaseJDBC</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create"/>
<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>
Then i added the required depoendencies to my Project (using maven) and the hibernate Plugin to Glassfish
What works: When ive created a table, in Netbeans i can Select New -> Other -> Persistance -> Entity Class from Database. The connection shows the tables, i select one, click okay, and i got the entity.
However i usually work the other way round and let hibernate generate my tables from the created entities... That whoever won't work. (It even looks like Hibernate is not even invoked, when building the project)
Did I miss any configuration step?
update: -------------
I wanted to test if hibernate is "active" in any way. So i created a simple entity, a controller and deployed the application with a single button.
public void doSth() {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("primary");
EntityManager em = emf.createEntityManager();
CEntity c = new CEntity();
c.setName("Test");
em.persist(c);
}
first, i received an exception:
Caused by: org.hibernate.HibernateException: The chosen transaction strategy requires access to the JTA TransactionManager
at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:376)
Overhere: hibernate, mysql, glassfish v3, and JTA datasource i found the solution to add
// For GlassFish:
hibernate.transaction.manager_lookup_class=org.hibernate.transaction.SunONETransactionManagerLookup
to the persistance.xml. The exception is now gone, but i received another one: Unknown Entity: CEntity.
I figured out, that hibernate can NOT find my entities. (Yes, i used javax.persistance.Entity and not the one from the hibernate namespace). However "adding" the entity manually to the persistance.xml solves the issue and also the automatic table-creation is invoked.
However, now im looking for the correct configuration, so adding every Entity to persistance.xml is NOT required.
I set <exclude-unlisted-classes>false</exclude-unlisted-classes> but hibernate seems to ignore that...
The key was to add:
<property name="hibernate.archive.autodetection" value="class"/>
to persistence.xml's properties-collection. After all:

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>
<user-name>root</user-name>
<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">

<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
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:
http://docs.jboss.org/jbossas/getting_started/v4/html/db.html
UPDATE: JBOSS 6 and newer has been rewritten to be more modular. You have to add JBDC drivers to your /module directory.
