Hibernate/JPA doesn't work -
this third question far trying fix this. tried lot of things, yet keeps failing , throwing exact same error on , on. let's see if can me time.
see, persistence.xml:
<?xml version="1.0" encoding="utf-8" standalone="no"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" version="1.0" xsi:schemalocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="pruebaswebpu" transaction-type="jta"> <provider>org.hibernate.jpa.hibernatepersistenceprovider</provider> <jta-data-source>java:app/jdbc/nuevaconexion</jta-data-source> <exclude-unlisted-classes>false</exclude-unlisted-classes> <!-- hibernate properties --> <properties> <property name="javax.persistence.schema-generation.database.action" value="create"/> <property name="hibernate.dialect" value="org.hibernate.dialect.mysqldialect"/> <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.improvednamingstrategy"/> <property name="hibernate.connection.charset" value="utf-8"/> <property name="hibernate.validator.apply_to_ddl" value="false"/> <property name="hibernate.validator.autoregister_listeners" value="false"/> <property name="hibernate.show_sql" value="false"/> </properties> </persistence-unit> </persistence> it connects wamp mysql server via jndi connection pool "jdbc/nuevaconexion".
here try use (just testing purposes, entity!):
public class samplepersistence { public static void main(string[] args) { entitymanagerfactory emfactory = persistence.createentitymanagerfactory("pruebaswebpu"); entitymanager entitymanager = emfactory.createentitymanager(); entitymanager.gettransaction().begin(); testentity ent = new testentity(); ent.setid(5l); ent.setnombre("one name"); entitymanager.persist(ent); entitymanager.gettransaction().commit(); entitymanager.close(); emfactory.close(); } } i error, strange because tells me change provider, but... it's changed. check:

it seems persistence.xml file cannot validated. either contains invalid character (check encoding, bom...) or schema cannot resolved (you should remove declaration xsi:schemalocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd").
