  <p>I am trying to resolve it since 3 days but no luck,</p>
  
  <p>I am importing correct Entity class javax.persistence.Entity; and using Entity class name in HQL "from EdbmsEmployee edbmsEmployee where edbmsEmployee.employeeid=?" (Code is running fine before this line giving exception on this line only)</p>
  
  <pre><code>  session session SessionImpl(PersistenceContext[entityKeys=[],collectionKeys=            []];ActionQueue[insertions=[] updates=[] deletions=[] collectionCreations=[]  collectionRemovals=[] collectionUpdates=[]    unresolvedInsertDependencies=UnresolvedEntityInsertActions[]])
  Sep 30, 2014 11:17:49 AM org.apache.catalina.core.StandardWrapperValve invoke
  SEVERE: Servlet.service() for servlet spring threw exception
  </code></pre>
  
  <p>and in my Entity class i have used all annotation correctly.
  then why i am getting this Exception "EdbmsEmployee is not mapped".</p>
  
  <p>I have googled the solution and found that this exception is come if we import wrong Entity class or if we've used table name in HQL.
  In my both is correct.
  And I believe while working with these annotation no need to map my entity class in xml file.</p>
