Camel JPA - No Persistence provider for EntityManager named camel

Hi,

I am trying to get the following code to work so I can consume from a JPA
entity.

String DATASOURCE_CONTEXT = "java:jboss/datasources/WikiDS";

Connection result = null;
DataSource datasource = null;

try {
Context initialContext = new InitialContext();
datasource = (DataSource)initialContext.lookup(DATASOURCE_CONTEXT);

if (datasource == null) {
System.out.println("Data source is null");

else {
System.out.println("Data source is OK!!!");

catch(NamingException ex) {
System.out.println("Naming exception is: " + ex.getMessage());

SimpleRegistry reg = new SimpleRegistry() ;
reg.put("myDataSource",datasource);

CamelContext context = new DefaultCamelContext(reg);

ConnectionFactory connectionFactory = new
ActiveMQConnectionFactory("vm://localhost?broker.persistent=false");
context.addComponent("test-jms",
JmsComponent.jmsComponentAutoAcknowledge(connectionFactory));
context.addRoutes(new RouteBuilder() {
public void configure() {

from("jpa://org.apache.camel.example.jmstofile?consumer.namedQuery=step1犉枃穗=false").to("file://test");

});

ProducerTemplate template = context.createProducerTemplate();
context.start();

Whatever I do I get the following exception.

[ERROR] Failed to execute goal
org.codehaus.mojo:exec-maven-plugin:1.1.1:java (default-cli) on project
camel-example-jms-file: An exception occured while executing the Java class.
null: InvocationTargetException: No Persistence provider for EntityManager
named camel.

Any ideas how to fix this?

Regards,

Sean
