Exception Handling in ADF 10g

Question

Hi everybody,
I want to develop an application and need exception handling.
I have a helper application that contains this classes:
MyADFPhaseListener extends ADFPhaseListener that return this: return new MyFacesPageLifecycle(),
MyErrorHandler extends DCErrorHandlerImpl,
MyFacesPageLifecycle extends FacesPageLifecycle that contain this methods:
prepareModel(LifecycleContext ctx) that set my errorhandler with this: ctx.getBindingContext().setErrorHandler(new MyErrorHandler(true));
and
reportErrors(PageLifecycleContext ctx){
DCBindingContainer bc = (DCBindingContainer)ctx.getBindingContainer();
if (bc != null) {
ArrayList<Exception> exceptions =new ArrayList<Exception>();
exceptions = bc.getExceptionsList();
if (exceptions != null) {
/*handle exceptions*/
My problem is here:
when throw an exception in my app like this: throw new JboException("Don't do that.", "101", null);
after create pagelifecycle and calling prepareModel(), reporterros() dose not call....!!!
why?

Answer 1

when click a button and call action of this button.
please note:
My helper application and main application are apart. I deploy helper application to jar file and use this jar file in main application.
Maybe exceptions don`t send to reportErrors() method in MyPageLifeCycle class, because i create a test class like this:
public class test {
public static void main(String[] args) throws SQLException {
ArrayList<Exception> exss = new ArrayList<Exception>();
exss.add(new JboException("A fatal exception is occurred",
"103", null));
exss.add(new NullPointerException());
exss.add(new SQLException());
MyFacesPageLifecycle efpl =new MyFacesPageLifecycle();
efpl.errorReporter(exss);
Body of errorReporter(ArrayList<Exception>) method is like reportErrors(PageLifecycleContext) just parameter is different.
public void errorReporter(ArrayList<Exception> excs) {
if (excs != null) {
for (Exception exception: excs) {
if(exception instanceof JboException){
System.out.println("JBOException is occurred here: "+exception.getMessage());
else if(exception instanceof SQLException){
System.out.println("SQLException is occurred here");
else if(exception instanceof NullPointerException){
System.out.println("NullPointerException is occurred here");
else{
and this handle exceptions list. My opinion is that exceptions between different applications(helper and main) are lost. is this correct?
