Using callStoredProcedure / callStoredFunction though a library/Class

Question

Jdev 11.1.1.3.0
I been using callStoreProdure /call StoreFunction as explained in fusion middleware guide http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/bcadvgen.htm#insertedID5. It works perfectly fine.
As, i have to call the above methods many place at Entity level / View level so i would like to bundle them into a library / class file and using them through the library rather pasting the meothd in all instance where i need them.
If i try to create a class file containing the above method then it could not resolve getDBTransaction(). With my y limited knowledge of Java i am clue less.
protected Object callStoredFunction(int sqlReturnType, String stmt,
Object[] bindVars) {
CallableStatement st = null;
try {
//1. Create a JDBC CallableStatement
st =
getDBTransaction().createCallableStatement("begin ? := " + stmt + "; end;",
0);
//2. Register the first bind variable for the return value
st.registerOutParameter(1, sqlReturnType);
if (bindVars != null) {
//3. Loop over values for the bind variables passed in if any
for (int z = 0; z < bindVars.length; z++) {
//4. Set the value of user-supplied bind vars in the stmt
st.setObject(z + 2, bindVars[z]);
//5. Execute the statement
st.executeUpdate();
//6. Return the value of the first bind variable
return st.getObject(1);
} catch (SQLException e) {
throw new JboException(e);
} finally {
if (st != null) {
try {
//7.Close the statement
st.close();
} catch (SQLException e) {
e.printStackTrace();
thanks
best regards

Sanjay,
Just create a custom base class for your EO/VO (this processes is also described in the fusion developer's guide) and put the method in there.
