          and got the following error

           

          Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named Allenavita

            at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:69)

            at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:47)

            at com.ibytecode.client.utility.ClientForSave.main(ClientForSave.java:18)

          I downloaded the jboss server and modified the standalone files, so changing the datasource

           

          <datasources>

                          <datasource jndi-name="java:jboss/datasources/OracleDS" pool-name="OracleDS" enabled="true" use-java-context="true">

                              <connection-url>jdbc:oracle:thin:@localhost:1521:xe</connection-url>

                              <driver>oracle</driver>

                              <security>

                                  <user-name>SYSTEM</user-name>

                                  <password>puffo</password>

                              </security>

                          </datasource>

                          <drivers>

                              <driver name="oracle" module="com.oracle.ojdbc6">

                                  <xa-datasource-class>oracle.jdbc.OracleDriver</xa-datasource-class>

                              </driver>

                          </drivers>

                      </datasources>

           

           

          Then i insert oracle.ojdbc6 in modules-com di jboss..Then I created the persistence file:

           

          <?xml version="1.0" encoding="UTF-8"?>
