[Manoranjitham G <ma...@polarisft.com>]

Hi All,
   I am doing a POC in apache camel to pick data from a file and save it in
database
consumer- file
producer - jpa - when executing the program am getting the below exception

*"org.apache.openjpa.persistence.ArgumentException: The persistence provider
is attempting to use properties in the persistence.xml file to resolve the
data source. A Java Database Connectivity (JDBC) driver or data source class
name must be specified in the openjpa.ConnectionDriverName or
javax.persistence.jdbc.driver property. The following properties are
available in the configuration:
"org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl@442ce698". *

this is my 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" version="1.0">
