Java.sql.SQLException: User: fusionEJB3, failed to be authenticated

Question

Dear experts,
My intention was to call a pojo, (ProductCatalog) from a servlet (SimpleRestServlet) in order to query a db entity for products in xml form.
The original thought was to be able to get the products via a servlet, but the entity manager is null:
Thus, what I get is:
Target URL -- http://localhost:7101/example8-1/products.jsp
DoGet invoked on RESTful service.
<Aug 22, 2011 7:12:09 AM GMT> <Error> <HTTP> <BEA-101020> <[ServletContext@335926353[app:chapter8 module:example8-1 path:/example8-1 spec-version:2.5]] Servlet failed with Exception
java.lang.NullPointerException

     at com.soacookbook.web.SimpleRestServlet.doGet(SimpleRestServlet.java)
     Truncated. see log file for complete stacktrace
However, if I create a stateless session bean, the generated java SE client is working well!
I start with the error logs; the full code will follow.
If i use the servlet to access the product entity I get:

public List<Product> getAllProducts(){

entityManager= entityManagerFactory.createEntityManager(emProps);
Query query= entityManager.createNamedQuery("Product.findAll");

return query.getResultList();
Thanks in advance for any help!

Strangely, the password string fusionEJB3, however changed to:
<property name="javax.persistence.jdbc.password"
value="57DAF0ADC12F7C37C6EC6D357C70ABD33754E34C120EB192D80F6E3B564BA6C8"/>
