Calling Stored function and showing returned value on the UI screen

Question

I am calling a stored function by using the following steps mentioned as per the below link. The stored function returns a single scalar value
http://download.oracle.com/docs/cd/E1790401/web.1111/b31974/bcadvgen.htm#sm0297_
Please verify if I am putting the code in the classes as required by the ADF framework.
* 1) In class CustomApplicationModuleImpl extends ApplicationModuleImpl*
// Some constants
public static int NUMBER = Types.NUMERIC;
public static int DATE = Types.DATE;
public static int VARCHAR2 = Types.VARCHAR;
protected Object callStoredFunction(int sqlReturnType, String stmt,
Object[] bindVars) {
CallableStatement st = null;
try {
// 1. Create a JDBC CallabledStatement
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. Set the value of user-supplied bind vars in the stmt
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) {}
With a helper method like this in place, calling the func_with_no_args procedure shown in Example 37-7 would look like this:
*2) In class CustomServiceImpl extends CustomApplicationModuleImpl*
public String callEnvironmentName(){
return (String) callStoredFunction(VARCHAR2, "CAR_UTIL_PK.get_environment_name()", new Object[] {});
3) If I have the first two steps correct, I was to display the value returned by method callEnvironmentName() with scalar values like (Development, Production etc) at the footer of each JSFX page. What is the flow I should follow, should I call callEnvironmentName() from some managed bean? Also I want to store it once on first call to some application variable and use that to populate the JSFX pages. Is there a working example. What is the best practice?
Thanks

Hi John,
Duplicate alerts are coming for BP_Confirmed as well as one custom event. Earlier I thought there is some issue with my custom event, but when it came for BP_Confirmed also, then i have a doubt something is wrong with the application.
I have also checked that BP_Confirmed is being raised only once inside the method-BP_CONFIRM of class-cl_crmcmp_b_cucobupa_impl.
raise event BPConfirmed
  CLASS cl_crm_ic_services DEFINITION LOAD.
  CREATE OBJECT event.
  event->set_name( if_crm_ic_events_con=>gc_bpconfirmed ).
  event_srv = cl_crm_ic_services=>get_event_srv_instance( ).
  event_srv->raise( event ).
Are you aware of any other place from where this event is getting triggered?
Thanks for your help!
Regards,
Rohit
