I did not create any table in my database. does hibernate create one automatic during mapping?

Answer 1

try to change this statement to make your code less in number of lines First.

<context:annotation-config/>
    <context:component-scan base-package="org.rajan.csci7795.service" />
    <context:component-scan base-package="org.rajan.csci7795.model" /> 

with

<context:annotation-config/>
    <context:component-scan base-package="org.rajan.csci7795" />

Now There may be a problem with this statement

<beans xmlns="http://www.springframework.org/schema/beans"
   ...........
   ...........
   ...........
   ...........
     xmlns:context="http://www.springframework.org/schema/context">

Please copy this piece of with any other source might help you out.

ERROR: Invalid object name 'Employee'. Have you focused on this ?? You have used @Table(name = "Employee") . Please verify your table name First. is it Employee or Exists with any other Name ?

you may change you code of DTO Class Employee

@Table(name = "Actual_Table_Name_Found_in_Database");
