I'm using JPA and have a persistence.xml with the following configuration:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"

<property name="hibernate.c3p0.timeout" value="100" />
</properties>
</persistence-unit>
</persistence>
The problem is that when i try to initialize my tomcat i got the following error:
691 [Thread-2] ERROR org.hibernate.connection.ConnectionProviderFactory - Could not instantiate connection provider
java.lang.ClassNotFoundException: org.hibernate.connection.C3P0ConnectionProvider
In my pom.xml (i use maven), i have the following dependency:
<dependency>
<groupId>c3p0</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.1.2</version>
</dependency>
That class is part of hibernate-c3p0. You will need to add a dependency
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>4.2.7.Final</version>
</dependency>
or whichever version you need.

hi all i got two different error when i run my java apps using hibernate persistence.xml
1. Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named FastMatch
2.Caused by: java.lang.ClassNotFoundException: Could not load requested class : com.mysql.jdbc.Driver
for the first error i have add my persistence.xml like this one :
here my persistence.xml
<?xml version="1.0" encoding="UTF-8"?>

A better idea will be to create two datasources in WildFly and then reference them in your persistence.xml files:
<persistence-unit name="pl4smsMYSQL-persistence" transaction-type="JTA">
<jta-data-source>java:jboss/datasources/MySqlDS</jta-data-source>
...
</persistence-unit>
<persistence-unit name="pl4sms-persistence" transaction-type="JTA">
<jta-data-source>java:jboss/datasources/PostgreSqlDS</jta-data-source>
...
</persistence-unit>
The great majority of your configuration properties then become redundant.
This will also have the benefit that your servers will be independently configured for each environment so you won't need different application builds for test and production.
Note that you can then also remove the driver jars from your application as they are separately deployed to the server.

Maven Dependencies
I could help know why not recognize the MultiTenantConnectionProvider class?
If you check the readme in hibernate-entitymanager it says
Hibernate's JPA support has been merged into the hibernate-core
module, making this hibernate-entitymanager module obsolete. This
module will be removed in Hibernate ORM 6.0. It is only kept here for
various consumers that expect a static set of artifact names across a
number of Hibernate releases. See
https://hibernate.atlassian.net/browse/HHH-10823
Now, you need to use hibernate-core
The MultiTenantConnectionProvider is located in
org.hibernate.engine.jdbc.connections.spi package of `hibernate-core`
You can include this maven dependancy:-
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.0.7.Final</version>
</dependency>
I'm using JPA for my persistence for my project and don't really know anything about hibernate but most tutorials I follow have found to setup connection pooling use c3p0 and hibernate.

How do i test if the connection pooling is working? I don't see a log displayed to my output
Please find the logging configuration here http://www.mchange.com/projects/c3p0/#configuring_logging
There you can find how to switch on debug to see if pooling happens.
Our application has a need to share an existing database table with another locally running application, and, so, I wish to refer to this table but skip generating the DDL for it. I also hoped to define the table in the application's schema as an alias or MySQL merge table, but I can add that to a manual script that will run before the generated schema script.
How can I specify that the create and alter table DDL for the shared_schema table are omitted from the myapp-schema-ddl.sql output?

I don't think Hibernate supports that directly. You could make two config files: one that lists all the mapped classes for runtime and one that omits the offending class for schema generation. Otherwise, you might look at some kind of post-processing, like a sed script, to remove the DDL after the fact.
