Validate method on EoImpl

Question

hi jdev groups
using 11.1.1..5.0-adfbc
i had a validate method in particulalr xxxeoimpl class.
Reason: while perform tab out in ui the function will fires. well it performs it's work correclty.
code in Eoimpl class
    public boolean validatexxxSubTerr(String xxxsubterr) {
        if(xxxsubterr!=null){
             setAttributeInternal("xxxTerrId",FuncFindTerritory("somevaluevalue",prospsubterr));
        else{
           throw new JboException("Territory Not Found") ;
        return true;
  code in Eoimpl class
    public String FuncFindTerritory(String pbu, String pxxxsubterr){
        CallableStatement cs = null;
        try{
        cs=getDBTransaction().createCallableStatement("begin ? := FUNC_FIND_TERRITORY(?,?); end;",0);
        cs.registerOutParameter(1, Types.VARCHAR);
        cs.setString(3,pxxxsubterr);
        cs.setString(2,pbu);
        cs.executeUpdate();
        return cs.getString(1);
        catch(SQLException e){
        throw new JboException(e);
        finally
        if (cs!=null)
        try{
           cs.close();
         catch (Exception e){System.out.println (" Function Find Territory Exception Thrown "+e);}
    }my question is : I use this FuncFindTerritory in most of the eoimpl class.
so i dont want to duplicate the same FuncFindTerritory in all eo class.
is there any chance to define this function in am module access/call this function in eo particular validate method.
setAttributeInternal("xxxTerrId",FuncFindTerritory("somevaluevalue",prospsubterr)); // this what i meanif wrote like this means i have to define method(FuncFindTerritory) in eoimpl class.
instead of doing like this..
Adf provides to access the methods which is define in am? is there any way...
sorry for updating late.
thanks&&regards

In theory you can access the AM from the EO but you should not. An EO represents one row of a table whereas the AM represents the the whole business logic. From this point of view where is no reason why an EO should need access to the AM.
Extending is a normal java mechanism which is wildly uses in frameworks. If you read the dev guide you'll find a paragraph which encourages you to build an extension for each framework class (for just this reason). This extension classes can hold all the stuff which is global for your application.
