Hi,
After importing the attached pex file, you will notice that the object is
died or de-instantiate immediately after the "self.close()" method in
display() method!

Object Life Cycle service Vs. Naming service
Hi,
In tuxedo CORBA, I find that Object Life Cycle service & Naming service have something
similar that the are both used to find object reference, aren't they?Then, I'm
interested in what make them diferrent in this action(find object reference) and
why to use one but not the other one?I can't be very clear from the docs.
Thanks and Regards
GeorgeYou are correct in that there is some overlap here (ask OMG about
this...). BEA historically recommended the use of the FactoryFinder
(BEA did not initially even support the Naming Service) since the whole
intent of the FactoryFinder was to "provide a naming service for Factory
objects" (rather than for instances). BEA believed that this was a
"best practices design pattern" to building scalable applications. Of
course, there is nothing preventing you from using the Naming Service to
do exactly the same thing and in fact, many existing applications were
written using the Naming Service in this way (since most other ORB
vendors did not implement the FactoryFinder) and as such, BEA added
support for the Naming Service.
Hope this helps,
Robert

Life cycle of a web dynpro callable object
What is the life cycle of a web dynpro callable object.
Means when that Web dynpro callble object is used in a GP process which method of that component called first and what is the sequence of the method execution in that.
Can anyone please explain me.Sorry ritu there was one mistake in the above two replies.
The actual execution of the methods when a callable objects is get executed is as following
1.component controller's init() method
2. interface's init() method
3.view's init() method.
4.interface's execute() method
5.view's wDoModifyView() method.
If you want to change anything on your view according to the change in the interfac's execute method.
Then you have to do that coding in view's wDoModifyView() method.
with regards
shanto aloor. -
Component life cycle doesn't apply to objects created w/in ActionScript block??
i don't understand why init() is never called. typically one can initialize variables in the constructor, but since this is mxml, the constructor is automatically created for us and the programmer seems to have no access or override privileges. so what to do?? am i failing to grasp some aspect of the component life cycle process?? how should i go about initializing properties??

NOTE: the code above might seem a little ridiculous, but that's b/c i reduced it down. imagine a baseComponent and derivedComponent where the myString has a default value in the base case and needs to be overridden in the derived case. appreciate any insights and thanks,

I suppose I should have been more aware about when the initialize event gets dispatched -- the concept just wasn't registering for me and I was totally miffed about how to initialize variables on construction.
Do you have to initialize before the instance is added to the display list?
Yes, I was mixing both mxml and AS classes and the derived classes had no display objects to attach to the stage (they were mostly classes made to modify run time behavior). You can check out my previous post, which gives the code for where or why this might be needed.
I ended up initializing mxml class variables during construction in the following way:
------------------------------ classes/BaseClass.as ------------------------------
package classes
public class BaseClass
public var myString:String = "hello, world";
public function BaseClass() {
init();
protected function init():void {
// intentionally left empty

What method is called only once in the life cycle?
Hello,
What method is called only once in the life cycle of an Entity Bean and Session Bean?
Is it ejbRemove()?
Thankshi,
ejbCreate() and setSessionContext() are called once by the container after the bean instace is created.when the bean instance goes to pool and again return to ready state to handle client requests these methods r never called .only bussiness methods r called.this is in case of stateless session bean.
in case of stateful session bean, each bean instance is associated with client.so,when new client requests, new bean instance is created and above 2 methods are called. no pool terminology in case of stateful session bean.
ejbRemove() is called by the container when it is abt to remove bean instance,so it its obvious tht it is called only once. -
Hi. I want to ask a few questions about the life cycle methods of Windows Phone App:
the OnNavigatedTo and OnNavigatedFrom, when is that methods called and what method is called when app goes to background, the screen locks(screen saver) and when app resumes? Thank you.Hi,OnNavigatedTo
this method call after the initialization section.I recommend you load your data asynchronously. OnNavigatedTo is
one place where you can start the loading.
OnNavigatedFrom:- This
method call when application leave the page.OnNavigatedFrom is one place where release application page resources/clean
memory/clean Back stack entry etc.eg-If application running and you press back button/start button then this method call.
Don't
forget to mark the right answer and vote up if helps you. -

I'm not sure what your applet is suppose to do but i've made some changes. I've moved your Container object declaration out of the "init()", and instead of "pressButton" I changed it to "pushButton" and "display()" to "con.setVisible(true)".

Re: [SunONE-JATO] Re: Using an object to store and display data
Personally, I think there is little or no value to creating a "domain"
object that itself relies on a JATO QueryModel internally, but hides that
fact and requires use of BeanAdapterModel.
It would be more appropriate (and much less work, and more scalable) to just
derive a QueryModel subclass and add the domain-specific behavior to the
model. In other words, what's the point of creating an object that hides
JATO inside it when you're running in JATO to begin with? Now if the domain
object were doing plain JDBC, and thus trying to be JATO independent, that
would be different. However, you could still implement the Model interface
on the object (or use BeanAdapterModel) to integrate it seamlessly with the
View tier.

Subject: [SunONE-JATO] Re: Using an object to store and display data
Craig,
I think it all finally makes sense. First, your assumption is
correct regarding the process flow. The ViewBean will interact with
a custom Javabean which will then in turn interact with a SQL Model
to access the database. So now let me make sure I understand what I
need to do. Basically the custom Javabean will have a method to get
the SQLModel. I would then invoke the setValue method on the
SQLModel and call the appropriate execute method( e.g.,
executeUpdate, etc. ) just like I would do from a ViewBean. Does
this sound correct?
Thanks,

Not sure what you mean by "interface this BeanAdapterModel ... witha
query model". Does this mean that you have a ViewBean the interactswith
a custom JavaBean via the BeanAdpterModel wrapper, and from the
JavaBean you are interacting with the SQL Model?
So it looks like this: ViewBean > BeanAdapterModel(Custom JavaBean)
SQL Model > RDBMS
That's what I am reading anyway. Please explain this to me.
Would I need to make direct JDBC calls
from my custom model instead of letting JATO dynamically create
the
calls for me?
If my assumptions above are correct, then the custom JavaBean cansimply
use the SQL Model in exactly the same manner as the ViewBean,otherwise,
if no SQL Model is involved, then yes, you need to handle JDBCdirectly,
which is fine, if you do it "right" (connection pooling, result set
handling, etc.).

You need to make an explicit call to super.Display() in the Display() method of your subclasses. Alternatively, you can delete the Display() method in your subclasses if there is no additional functionality there.
You seem to be getting a bit confused over inheritance and overriding. If you override a method in a subclass (ie have a method with the same name and parameters), you will lose the functionality of the superclass's method - unless you explicitly call the super method. If you DON'T override it, you will inherit it automatically!
If you write a good framework for your application, you will rarely need to have a Display() method in your bottom level classes, as all required functionality will be inherited. Please let me know if you would like some tips on the development of such a framework (or if I haven't made any sense).

Subject: Inherited display method
I am trying to modify the display method in a custom window super class.
Within my application, the user should be able to hit the F3 key to
exit. I have coded it in a display method on a particular window and it
works. However, when I attempt to move the code to the parent window
class (so that I don't need to repeat the code for every window
subclass) it doesn't work. It seems that the display method isn't being
inherited (even though the books say that they are). After having
modified my display method in the window super class, I created a
subclass based on the super class. When I opened the display method for
the subclass, only the default code appeared, not the custom code that I
had created for the superclass.
Any assistance would be appreciated. It seems to defeat the purpose of
OO if I can't create a custom display method in a super class and have
it inherited by the subclass.

Well as cbacher has mentioned, if your Thread is running and you call the start method a InvalidThreadStateException will be raised, what you can do is like this, you can have ur class implement runnable as this will also you to call the run method multiple times using the start().
Your run code could have some kind of a check to see if the external event has occured, if not it should continue doing the process else it should finish the execution of the run method, thereafter you could call the start method again to restart the thread, that way you will not be essentially creating a new Thread object( you are calling start on an existing object). Hope this was useful.

Where in the MIDlet life-cycle should I create multiple forms with LWUIT ?
Hi all,
I must create two LWUIT forms in my application. Where should I create the two forms ? I created the first form in the startApp life-cycle method , and when I tried to create also the second form in the startApp method then there is a NullPointerException raised when running the application !
So where , or how , should I create the second form ?
Thank you very much indeed
Edited by: andrianiaina on May 20, 2011 1:59 AMI think the problem here is that Arlhoolie wants all of the different TEBs to behave as if they were part of a single interaction that submits only ONE result to the quiz. Using multiple TEBs in Captivate means that you have multiple scored objects and therefore multiple results being submitted to the quiz.
If you want a single Success or Failure result submitted to the quiz based on the results from multiple interactive objects then there really is no simple way to do it. But you could try using the Infosemantics Interactive Master widget to combine all the TEBs as slave objects that report to the Master Widget, which then reports a single score to the quiz based on the results from the slave objects.
You can learn more about the Master widget here:

You can download a free trial version of the widget here:

One caveat you should be aware of is that this widget is not HTML5 compatible. -
Regarding SLCM (Student Life Cycle Management)
Hi
does any one working on Student Life Cycle Management(SLCM)
can any one pls let me know what are the function modules present in the predefined business package and how to know what are the predefined functonalites given by sap.
when i test the predefined Iviews i get an error for some of iview as student object id not found.
can any one pls let me know about this
ByeOk Fine
I have some points to share thise issue with u
first thing is , iam using wrong application for the requirement.
and even i use wrong apps some thing result should be show, as i said the error i got
we raised an sap Oss for this, they provided the solution as stating that we are using the apps which are specific to the advisor but not for the students specially.
So if u want to use those apps for student purpose we need to get that student object and pass in our application.
for this purpose we need an abaper help who is well versed in the coding part.
just modify the code of required application where u fetch the object id (BY Coding) in ithe intialization method,
then the appication works fine
this is the solution i got and all my apps are working fine now.
Thanxs

Jsf 1s phase of life cycle how knows ths components of the jsp with jsf tag
i wish to know how faces servlet knows the jsp s view components while creaTI NG component tree at first request to input jsp which may have jsf tags.in the first phase faces servlet doesnot know input jsp with jsf tags what componnets it has. it is actually atthe response send or forward time which is the final phase when the tag ge executed and output is sent to client.i did understandin jsf life cycle in 1 st phase component tree is created at first request in 1 st phase .
Hi,
though a FacesContext holds the values used by a request, it doesn't mean it lives for as long as the request. The best explanation I found is from the JavaDocs
release
public abstract void release()
+Release any resources associated with this FacesContext instance. Faces implementations may choose to pool instances in the associated FacesContextFactory to avoid repeated object creation and garbage collection. After release() is called on a FacesContext instance (until the FacesContext instance has been recycled by the implementation for re-use), calling any other methods will cause an IllegalStateException to be thrown.+
The implementation must call setCurrentInstance(javax.faces.context.FacesContext) passing null to remove the association between this thread and this dead FacesContext instance.
Throws:
java.lang.IllegalStateException - if this method is called after this instance has been released
