Hibernate is return an array of String (aka a List of type String)

 List companyList = session.createSQLQuery ("select name " +
                                                  "from company "+
                                                  "where company_id= " + companyId).list();   

Because your query returns a String of names from Company table.

What you have to do return a List

 List companyList = (List)session.createSQLQuery ("select name " +
                                                  "from company "+
                                                  "where company_id= " + companyId).list();

Change your error, from this:

 vgDetails = new Route(); 
            Object[] row = (Object[])companyList.get(i);                                 
            vgDetails.setRouteName ((String)row[0]);                     
            routeList.add(vgDetails);

To this:

vgDetails = new Route();                                
vgDetails.setRouteName (companyList.get(i));                     
routeList.add(vgDetails);

as companyList.get(i) returns a String.
