PersistenceException UserException: Failed to validate persistence.xml

#1

I'm really tired of looking at the same exception all day.
I have DaoService which gets initialized when app starts.

public DaoService() {
  Map<String, String> properties = new HashMap<String, String>();
  properties.put("javax.persistence.jdbc.user", "admin");
  properties.put("javax.persistence.jdbc.password", "admin");
  factory = Persistence.createEntityManagerFactory("$objectdb/db/points.odb", properties);
      //exception!
}

But everytime it fires this exception: 

javax.persistence.PersistenceException: Explicit persistence provider error(s) occurred for "$objectdb/db/points.odb" after trying the following discovered implementations: org.apache.openjpa.persistence.PersistenceProviderImpl, com.objectdb.jpa.Provider from provider: com.objectdb.jpa.Provider

I tried with and without this persistence.xml

    <?xml version="1.0" encoding="UTF-8" ?>
    <persistence 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_1_0.xsd" version="1.0">
    
       <persistence-unit name="my-pu">
         <description>My Persistence Unit</description>
         <provider>com.objectdb.jpa.Provider</provider>
        
        
         <class>net.heatboxes.dao.entity.UserEntity</class>
         <properties>
           <property name="javax.persistence.jdbc.url"
                     value="my.odb"/>
           <property name="javax.persistence.jdbc.user" value="admin"/>
           <property name="javax.persistence.jdbc.password" value="admin"/>
         </properties>
       </persistence-unit>
    
    </persistence>

Please, tell me what I am doing wrong.

#2

> Failed to validate xml file C:\!heatboxes-web\build\web\WEB-INF\classes\META-INF\persistence.xml

The exception is thrown by the Java XML library due to a failure to open the XML file for validation.

What is the "!" character at the beginning of the path, is it part of your path? Could you try moving your project to a path with no special characters? I don't know if it would solve the exception but it is worth trying.

Thank you. But path acts right way. Finally I've got it. I should not use any persistence.xml at all. When I do not use it, I got this error:

HTTP Status 500 - <openjpa-2.2.0-r422266:1244990 fatal user error> org.apache.openjpa.persistence.ArgumentException: A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName property. Available properties in configuration are "org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl@fdaf18ee".

to avoid it, I removed openjpa-asm-shaded-X.X.X.jar from my TomEE lib folder.
