Persistence and generics

Question

Hello, I am having a problem with generics and persistence this code is throwing " java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to ejb.Name" exception.
"Name" is my entity class and I am trying to address it from the servlet to get some data from the database. the data is retrieved, if I put "List" instead of casting it to "List<Name>" the size of the list shows 500 records. As soon as I cast the result into list of names I get the exception. Can anyone help me with this issue, thanks.
{code} @SuppressWarnings("unchecked")
protected String getAll() {
String st = null;
try {
Context ctx = (Context) new javax.naming.InitialContext().lookup("java:comp/env");
EntityManager em = (EntityManager) ctx.lookup("persistence/LogicalName");
List<Name> names = (List<Name>) em.createQuery("SELECT p FROM Name p").getResultList();
for (Name t: names){
st += (t.toString());
return st;
} catch (Exception e) {
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE, "exception caught", e);
throw new RuntimeException(e);
}{code}

Well[Ljava.lang.Object;is an array of Object, see [Class.getName()|http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Class.html#getName()]
and [EntityManager.createQuery()|http://java.sun.com/javaee/5/docs/api/javax/persistence/EntityManager.html#createQuery(java.lang.String)] returns a Query
