Using Digester to create Java Objects to load XML file

Can somebody help me to create Java Object from this below XML file using Digester api.

I have a class Company has a map like this

  Map<String,Department> nameToDeptMap= new HashMap<String,Department>();

I want to load below XML data to this map.

     Department is super class. Development,Testing,Requirment...etc are extending that class. 


    <Company>
    <Employee empname="xyz" department ="com.compnayname.departments.department.Development>
    <Employee empname="xyza" department ="com.compnayname.departments.department.Testing>
    <Employee empname="xyzab" department ="com.compnayname.departments.department.Requiremetns>
    <Employee empname="xyzabc" department ="com.compnayname.departments.department.Production>
     .
     .
     .
     .
    </Company>

when the Map is loaded, I will pass the "empname" to get department Object.

If you want to know how I am doing please see below code. I know it is wrong.

My java files are like this..

I am able to write Digester rules to get the values from XML file as String but don't know how to get as a Object.

    Digester digester = new Digester();     
    digester.addObjectCreate("Company/Employee", Company.class);        
    digester.addCallMethod("Company/Employee", "setComapnyConfigMap", 2);
    digester.addCallParam("Company/Employee", 0, "empname");
    digester.addCallParam("Company/Employee", 1, "department");
