Breaking up data in a remote object

Currently I have a chart that gets its data using a remote
object connection. The chart currently shows a months worth of
data. Now I need to break that monthly data into weekly data. The
customer would rather have the data spread acroos four weekly
charts instead of just one monthly chart. The customer would then
just click click a 'Next' or 'Previous' button to cycle through the
charts.
I know that I just change the function (CFC) that calls for
the data to only return a weeks worth of data, but I don't want to
make a separate data call every time the user clicks 'Next' or
'Previous'
Is there a way to grab the whole month's data set and then
divide it into weekly data sets within the app?

Okay I figured this one out. If I add a hSlider with two
thumbs I can set the thumbs with just a couple of functions.
Basically when the user clicks either button a function is called
that passes in a predetermined value of how many tick marks to
move.
The HSlider has a property called 'values' that holds the
positions of all the thumbs. Using some simple functions they can
easily be manipulated.
Setting the slider's visible property to 'false' will keep
the navigation focused on just the buttons.

Creating remote objects and passing the retrieved data to modules

I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use?
I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.
Ultimately, I would like to know what the "best practices" are for creating remote objects and passing the retrieved data to modules
Thanks!

public void mouseClicked(MouseEvent e) {
X x = new X(e.getX(), e.getY());
}I don't see the difficulty.

How to call a function/event after a Remote Object's data is loaded?

I'm making a call to a remote object that is loading a good
amount of data. I've set up a "please wait" label that is supposed
to display while the data is being loaded and then clear the label
when the data finishes loading.
At the moment I've got it set up like so...
label = 'Loading data, please wait..."
remoteObj.read.send();
label = ''
The problem with this is that the 'please wait' label doesn't
even display because the actual call to the remote object I'm
making finishes so quickly even though the data load does not. So
what I need is possibly an IF statement to check if the data has
finished loading. If it hasn't finished loading, the label stays in
the "please wait" status, or if the data does finish loading, then
the label clears out.
What would be ideal is...
remoteObj.read.send(); // gets the data
if(data is loaded){
label = '';
}else{
label = 'Please wait'
I just don't know how to form the statement for the data
loading in the IF statement.

You are seeing the difference between data loading and UI
rendereing.
Reasonable amounts of data load very fast, expecially with
RemoteObject. Bur rendering the UI is almost always the bottleneck,
event with AS3 FP8+, which is about 30 percent faster than AS2!
I have not found a perfect solution for this myself, but i
think you will want to look into the component data events, to find
one that fires after the component is actually rendered.

HI ,
1. You cannot use a table or view that contains xml or clr type as 4-part name in your query
2. You need to cast the column to either nvarchar(max) or varbinary(max) or other appropriate type to use
3. If you have a table that has xml type for example then you need to create a view that contains all columns other than xml and query it instead. Or you can issue a pass-through query using OPEN QUERY with the appropriate columns only.
Here is a work around:
SELECT
Cast(a.XML_Data as XML) as XML_Data
FROM
OPENQUERY([LINKED SERVER NAME HERE],'
SELECT
Cast(XML_Data as Varchar) as XML_Data
FROM
[DATABASE NAME].[SCHEMA].[TABLE NAME]'
) a
Basically, the data is queried on the remote server, converts the XML data to a varchar, sends the data to the requesting server and then reconverts it back to XML.
You can take help from below link;

Data coming late by remote object

Hi, I am facing problem with data coming late by remote
object. the sample code is-
[Bindable]
public var isRelationExist:Boolean = false;
private var remoteLoginObject : RemoteObject = new
RemoteObject();
//some code
public function setCurrentNode(value:Node):void
remoteLoginObject.destination = "NodeRef";

RMI and Threads: Calling wait() on a remote object

I created a counter as a remote object.
Multiple clients are displaying the counter value.
If one of the clients increments the counter, I want the displayed counter value on every client to be updated to the new value (of the counter on the server).
Therefore every client starts a new thread to "listen" for changes of the countervalue. I wanted to call the wait() method on the remote object (the remote counter). But i think it will be called on the stub instead of on the actual remote object.
Therefore i created a extra method waitForChange() on the remote object.
public void waitForChange() throws RemoteException, InterruptedException {
     synchronized(this) {
          wait();
This method only calls the wait() method. Now I'm sure it's called on the remote object and not on the stub.
This works, but my question is: is there a better way to do this?

}This is just a little test. Actually I want to notify clients of changes in data displayed in a Table. If one client saves one record of the data, i want the new record to be displayed immediatly on all clients that are viewing the same data.

I've been doing some reading about RMI and callback.
As I understand it, there's a remote object is running on the client now as wel. And the server makes a call to the client.
But now the server makes a call to one client.
And the point is, I want all clients to be updated with the new value.
Does this mean, I have to keep a list with references to all clients connected to the server?
I my code the notifyAll() method causes all waiting Threads (running on several clients) to wake up and do something (getting the new counter value).

Move XMLTYPE data to a remote database

Hello,
I need your experience !!!!!
I am working with the 10.2.1 database.
I have try to call a remote procedure (using DBLINK) with a XMLTYPE parameter, I get a error link to a lob locator.
One solution could be to save XMLTYPE to disk.
Some body know other solution to transfer XMLTYPE data to a remote database.
Thanks in advance
Best Regards

A future alternative will be Oracle streams and b.t.w. one of the advantages (sometimes not, but anyway) of an Oracle database is that you can use object orientated methods, relational methods, java solutions, etc. and nowadays XML methods. XML was once all about transporting data, creating an uniform interface between solutions (databases, application/webservers, technology stacks, etc...). Think out of the Box. XMLDB isn't relational, but it is packaged in one. Make use of it and vice versa.

Two remote objects calls on the same php class

Hi to all,
I've encountered a strange issue while developing with remote objects.
I've a mxml component with an init() method inside which is called by a menu.
When the init() method is called it makes 7 remote object calls which are bound to some components' dataprovider.
Among this calls I've got 2 remote object which refer to the same remote class. This because I have to call the class twice and the bind the result to two different combobox. Below you find the code:
<mx:RemoteObject id="myFile" source="myRemoteClass" destination="amfphp" showBusyCursor="true" makeObjectsBindable="true" fault="traceFault(event)"/>
<mx:RemoteObject id="myXls" source="myRemoteClass" destination="amfphp" showBusyCursor="true" makeObjectsBindable="true" fault="traceFault(event)"/>
in the init function I make this calls:
myFile.listDir("dir_1")
myXls.listDir("dir_2")
then in the mxml code I bound the result of myFile to combobox1 and the result of myXls on combobox2.
The problem arise when I call the myXls' listDir method. When I call it I receive the following error:
code:
Client.Error.DeliveryInDoubt
Message:
Channel disconnected
Detail:
Channel disconnected before an acknowledgement was received
The strange thing is that not only the myXls object returns this error, but also all the other 6 remote object return the same error above.
I'm not sure, but I guess that the error could be caused by the two remote object which call the same php remote class. If I comment one of the two calls everything works fine.
Do you have any suggestion about?
Thanks!!
Bye

Hi Jan.
1) We have the 2 VO, each with 3 rows to fill in data. What I mean is that when i just fill in all the fields for the first row of the first VO, and the value of one of these fields is bigger than 50, then after the exception is thrown and the message is displayed, the fields for the first VO are duplicated and shown in the second VO as if the user had inserted them.
2) We tried yesterday the validateEntity and a Method and Atributte Validator approaches after reading that white paper with the same results.
The validation is correctly done using any of the those methods.
I will try to reproduce this issue with the HR schema.
Thanks in advance once again.

How to extract data from a remote system

Retrieving data from a remote DB using ODBC ?

Hi,
Has anybody tried to collect some data from a remote DB in InDesign plugin by using ODBC ? I want to know the basic steps including what I have to add in the Xcode project, how to connect to remote DB, and how to retrieve data in plugin by sql query ?
TIA,
Nima

I think you need to add /usr/lib/libiodbc.a to your Xcode project. also you will want to look into sql.h and sqlext.h assuming you're connecting to database such as MySQL to see what's the API you will use to communicate thru ODBC. But the code should be purely C++, nothing InDesign specific, you can write it as a separate library or an InDesign Boss object.
You will also need to install ODBC driver that's probably would be supplied by your database vendor. So for MySQL, there is a driver you need to download from MySQL site and install, and configure thru OSX's ODBC Administrator tool.
Thanks!

How does the remote object connect to the correct host

i have had a small doubt on how the remote reference manages to find the correct host to call the subsequent methods after a sucessful lookup.
given a rebind or bind to the registry, the registry only stores the alias and the remote reference, now imagine a client calling a lookup on the registry would only get the remote reference, and not in which machine the remote object is found.
what i wanted to know is how does the client or atleast the remote reference returned by the registry correctly connects to the machine where the remote object is located. i dont think its stored in the stub bcos the stub is a complie time stuff.
i would be pleased to have a comprehensive answer for this.

The membership in the group communication framework is always accurate and upto date.Up to date to the moment when you check. Not up to date to the moment when you make the RMI call.
i could basically chk if this ip is available in the membership list.Complete waste of time. It doesn't matter what you check ahead of time, you are still trying to predict the future.
And you still have to deal with ConnectException etc from the actual remote method call. And the way you will deal with that in your situation is exactly the same as what you were going to do if your ahead-of-time check failed.
So just catch the exception(s) and deal with the problem there.

Weblogic 10.3.0 issues with remote object calls.

All:
I was wondering if anyone has experienced any issues with Weblogic 10.3.0 dropping initial remote object calls over AMF Secure Channel. Here are the issues we are experiencing.
1. FLEX applications fail consistently on the first remote object call made across the AMF Secure Channel. Resulting in the request not returning from the application server; which has had varying affects on the different applications including missing data, application freeze and general degrading of the user experience.
2. FLEX applications require a browser/application refresh once the application has been inactive for a certain period of time. In our experiences the behavior occurs after 30 minutes of inactivity.
I've deployed this same code to Weblogic 10.3.3 and the behaviors go away. Are there any patches to 10.3.0 that might take care of this issue that we are not aware of?
Thanks for you help,
Mike

Client code cast error:EJB returning data in Collection of Objects

Still trying to understand this EJB stuff.....
My BMP EJB returns data to the client in a collection of objects;
// Home interface (CountryHome) nothing unusual here
public Collection findAllCountries()
//Remote interface (Country) nothing unusual here
public CountryModel getDetails()The data object is a serialised object;
// data object - nothing strange here
public class CountryModel implements Serializable {
    private int countryId;
    private String countryName;
    public CountryModel () {......etc etc
    public CountryModel getDetails() {.......etc etc
    public String toString() { ...etcWhen I try and get at the data from the collection in the client code, calling getDetails() in CountryModel causes a cast exception. How can I get at the data?
Collection a = home.findAllCountries();
Iterator i = a.iterator();
while (i.hasNext()) {
    Object obj = i.next();
    Country country = (Country)
         PortableRemoteObject.narrow(obj, Country.class);
    // this fails with class cast exception.....
    System.out.println(country.getDetails());And to add to the confusion, why does calling the remote interface's getPrimaryKey() method in the client code invoke the toString() method in the CountryModel class and work?
while (i.hasNext()) {
    Object obj = i.next();
    Country country = (Country)
         PortableRemoteObject.narrow(obj, Country.class);
    // have no idea why this works.....but it does.....
    System.out.println(country.getPrimaryKey());Thanks, lebo

hi,
you are getting a collection of serializable objects and not remote objects. the narow method has to be applied only for remote objects (actually it is the stub that will be received on the client side).
so you modify your code as,
Collection a = home.findAllCountries(); Iterator i = a.iterator(); while (i.hasNext()) {    Object obj = i.next();    Country country = (Country)obj;
this will definitely solve the problem.

Mapping: ORA-04052 Remote Object not found

Hi,
I created a source module with a table reading from an external Oracle database. I can see data so the connection seems to work.
In the target module a mapping trying to read from this table can´t be deployed with this errors message:
- ora-06550: package body, line 0, column 0: ORA 04052: Error while trying to find the remote object: <name of the object> ....... ora-02019: connection description for remote-database not found.
An equal internal mapping, not adressing an external database, works find.
Any idea?
Thanks so much.
Georg

oh, of course.
I could not find dblink, saw some source information. What section/s is /are to be checked?
I find code like
SELECT
/*+ NO_MERGE */
/* OBJSTAMM.INOUTGRP1 */
"OBJSTAMM"."OBJEKTNUMMER" "OBJEKTNUMMER"
FROM
"VMAN30M"."OBJSTAMM"@"PDORA06@QUELLE_VISMAN_LOCATION" "OBJSTAMM"
Is there a way to find out the correct "from" path?
Thanks Georg
