Binding ActionScript object to webservice

Hi,
Can someone please provide me with simple example as to how
to bind an ActionScript object to the webservice.
The Scenario is I have an actionscript class. I have the
webservice in the mail mxml. I want to create an object of the
class and want to bind that object to the webservice rather than
binding each of the property.
Thanks in advance.

Do not bind directly to a webService result. Use a result
handler, and assign the result to a bindable variable. Bind to
that.
To intercept binding events in AS code, use a ChangeWatcher.

Newbie: binding actionscript var to textinput

Hi,
I'm just starting with flex, and have a simple question on
bindings. I've created the following application (using flex3 beta
3, and flexbuilder):
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Script>
<![CDATA[
[Bindable]
public var customerName:String = "customerName";
]]>
</mx:Script>
<mx:TextInput text="{customerName}" x="187" y="92"/>
<mx:Text text="{customerName}" x="368" y="94"/>
<mx:Button click="customerName += 'z'" x="473" y="92"
label="add z"/>
</mx:Application>
The problem: the variable customerName isn't changed when i
enter some text in the textinput. Pressing the button does the
expected thing: changes the variable, which is displayed correctly
by the textinput and text components.
My goal is to create a datamodel using an actionscript
object. I've seen some examples where the datamodel is bound to the
textinput (the other way around), but it seems to me that it would
be better not to tie a datamodel to one single input component. I
may want to modify the data using multiple components.
Thanks,
Andrej

My 2 cents: There is often a misconception that when making a
variable bindable, it is a two-way binding, in other words, the
entity that is bound to the variable will be updated automatically
AND the variable will be updated if the entity's value changes (a
circular binding).
Making your variable [Bindable] means that there is a single
observer, like your TextInput, of a variable, like customerName. If
the customerName variable changes, then the TI will change, not the
other way around.
Your approach of using the Binding tag with a reciprocal
source and destination should be fine.
My approach usually is to set the initial value I want
displayed in the TI from elsewhere. Then the TI is strictly used as
the control to input data in order to update a variable on the
'change' event. I often bind to a function that'll automatically
perform XYZ for me on a specific event.

Creating and Binding View Objects dynamically : Oracle Jdeveloper 11g

Hello,
We are trying to create and bind view objects dynamically to adf data visualization components.
The view object is a result of multiple tables.
We are using Oracle JDeveloper 11g Technical Preview. ( can't upgrade to TP2 or TP3 now).
We have found this : http://radio.weblogs.com/0118231/stories/2003/07/15/creatingUpdateableMultientityViewObjectDefinitionsDynamically.html on our search for the same.
The sample application however, is in 10g , hence required migration.
Also, it was a standalone application with the TestClient.java having a main() method.
Our requirement is for Web Application; we use Adf+jsf .
Guidance of any sort is very much appreciated.
Thanks in advance.

Hi,
there also exist a forum for JDeveloper 11: JDeveloper and OC4J 11g Technology Preview
What you are trying todo is not trivial because you need to not only dynamically create the VO, you would also dynamically need to create the binding meta data for it (assuming you use ADF). Not sure if the API to modify the binding is public, so posting it on the JDeveloper 11 forum bears a glimpse of hope for an answer
In JDeveloper 10.1.3 you can't do this

Properly binding an object to a custom component.

I am apparently not doing this. What am I missing to properly
bind an
object from a repeater looping over an array of object to the
custom
component called in the repeater?
<mx:Repeater
id="dayCells"
dataProvider="{days}"
startingIndex="{weekRows.currentItem}"
count="7">
<mx:GridItem
width="14%"
borderColor="black"
borderThickness="1"
borderStyle="solid">
<mx:Label
text="{dayCells.currentItem.formatedDate}" />
<ian:dayFormat2
drawData="{dayCells.currentItem as drawDay}"
test="{dayCells.currentItem.formatedDate}" />
</mx:GridItem>
</mx:Repeater>
{days} is an array of drawDate.as objects returned with a
remoteObject.
I can correctly bind properties of these drawDate objects in
the
lable and the test property of the dayFormat2
customComponent. But I
can NOT correctly bind the entire object over to dayFormat2.
What am I
missing?
My current version of dayFormat2.mxml, I have tried several
alternatives
for this file.
?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="
http://www.adobe.com/2006/mxml"
width="100%">
<mx:Script>
<![CDATA[
import drawDay;
//Define public variables
[Bindable]
public var drawData:drawDay;
[Bindable]
public var test:String;
]]>
</mx:Script>
<mx:DateFormatter id="dayNum" formatString="DD" />
<mx:HBox
backgroundColor="0x002649"
width="100%"
horizontalAlign="right">
<mx:Label
text="{test}"
color="white" />
<mx:HBox
backgroundColor="0xAF1E2D"
horizontalAlign="center">
<mx:Label
text="{dayNum.format(drawData.date)}"
color="white" />
</mx:HBox>
</mx:HBox>
<mx:Label text="foobar" />
</mx:VBox>
The first label bound to the test String works correctly. The
second
label bound to the drawData drawDay object date property does
not work
correctly.
What is the proper way to bind this object?

I have struggled with this all day and made no headway. The
only
strange thing I get is with this line:
<mx:Label text="{dayCells.currentItem.toString()}" />
outputs [object Object]
Not the expected string from this drawDay.as function.
// toString()
public function toString():String
return "Date: " + formatedDate;

SingleTon object of WebServices (Please be specific as required and not be generic)

// Singleton Object of viewservice
private ViewService WorkListView = null;
ViewServiceObjectCreation viewstrWorkListView = ViewServiceObjectCreation.GetObject();
// Object Creation
public class ViewServiceObjectCreation
        private static ViewServiceObjectCreation singleTonObject=null;
        private static readonly object lockingObject = new object();
        private ViewServiceObjectCreation()
        public static ViewServiceObjectCreation GetObject()
            if(singleTonObject == null)
                 lock (lockingObject)
                      if(singleTonObject == null)
                           singleTonObject = new ViewServiceObjectCreation();
            return singleTonObject;
But this is not creating singleton object of webservice. How to create singleton object of webservice.
Vivek

Read my post again: Please describe your concrete problem which made you think you need a singelton.
A singelton only works per domain. Thus it will not help in your sketched scenario. Cause it cannot prevent an user or administrator for starting another domain (a.k.a. process).
In this case you should consider using a mutex, which is aquired when the web service is started and released when stopped.
While singeltons are a cool pattern per se, they are one of those evil ones. They are often not a correct solution and much worse, the kill testability cause the represent a global state.

Using JNDI to bind any object

Hi,
I intend to bind a few objects in JNDI context so that they can later be just looked up and then used.
I can use code like this:
=========
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, SOME_PROVIDER_URL);
env.put(Context.SECURITY_PRINCIPAL, "user");
env.put(Context.SECURITY_CREDENTIAL, "passwd");
Context ctx = new InitialContext(env);
context.bind("name", object);
=========
This object can later be looked up. So far so good. However, this will bind the object in the same VM "only".
Is there any way of calling something like:
====
someOC4JClass.getNamingService().bind("name", object);
===
so that the underlying naming service takes care of making this object available across JVMs?
Any help/pointers will be highly appreciated.
Thanks,
Ravi

Ravi -- Currently OC4J's internal JNDI is not a global JNDI shared by all OC4Js. One way to approach this problem would be to bind the objects in some global / common JNDI like OID.
Thanks -- Jeff

How can i return an object isn't java object from webservice????

Hi !
I have a problem in my Project. When i call method return a java object from webservice , it 's too easy. But when i create my own object (ex:ClientRequest.class) , it doesn't work exactly T_T . When i return that object (on client, doesn't have ClientRequest.class) , i cann't access its static variables.
How can i do it ??
Please help me !
Thanks a lot !!!!!
class ClientRequest {
public static int i;
public static String s;
public ClientRequest() {
}

You can use REFCURSOR type for this. In java SQL TYPES this is available too. In your PLSQL use REFCURSOR for that array and then take the same from java code. Look in the servelet programming book for this SQLTYPE and see PLSQL for handling refcursors. We have done this way and it works.

Although I have no idea of what you mean, I guess it have something to do with synchronized keyword or Object.wait() or event Thread.join().

ResultFormat="object" in webservice. Flawed or is it me??

<mx:WebService id="getListTargs"
wsdl="myurl/dropper.cfc?wsdl" useProxy="false">
<mx:operation result="testRet();" name="dropRanges"
fault="Alert.show(event.fault.message)" resultFormat="object"/>
</mx:WebService>
When I get the XML back from that webservice it comes back as
a string and not an object. Is something wierd with resultFormat or
do I have to do some kind of conversion to get it into an
object????

The code below is working to populate a class with the values
returned from a web service, ofcourse you have to create the class
and create the callback function but I believe you have to create
the class even with the full blown FDS Java implementation so it's
a trivial task.
This code is all AS, as I personally dont like using the
tags.
These are two load functions in a custom ArrayCollection, so
ignore the this. calls as they are just calling super class
functions.
public function LoadAllModules():void
var ws:WebServices = WebServices.Instance;
var op:AbstractOperation =
ws.Service.getOperation("GetAllModules");
op.addEventListener("fault", ws.Fault_Callback);
op.addEventListener("result", this.LoadAllModules_Callback);
op.send();
private function
LoadAllModules_Callback(result:ResultEvent):void
this.disableAutoUpdate();
for (var s:String in result.result)
var m:MyClass = new MyClass();
m.ModuleID = result.result[s].ModuleID;
m.Name = result.result[s].Name;
m.BaseName = result.result[s].BaseName;
m.AssemblyName = result.result[s].AssemblyName;
m.AssemblyNamespace = result.result[s].AssemblyNamespace;
m.Active = result.result[s].Active;
m.RemoteFiles = result.result[s].RemoteFiles;
this.Add(m);
this.itemUpdated(m);
this.enableAutoUpdate();

Perhaps what your trying to accomplish could be handled via a startup

Binding huge object to the jndi tree.

Hi we are loading all the master tables in to objects at the app server startup (SUN ONE 7) and then binding the whole object to the jndi tree. All the tables data in text files comes to about 5 MB and the serilized object with data to about 8 MB. But when the app server tries to bind the object the app server process consumes over 500MB of ram and gives OutOfmemoryError as the total ram is 512MB. why is it consuming so much memory. It does bind an object of about 5 MB but when trying to lookup subsequent to the first lookup it fails. Is this a bug or what??? the same thing works perfectly with Weblogic and Websphere and also Weblogic is very efficient in memory consumption and response time is amazing. For a 5 MB object the lookup takes about 5Secs in Weblogic and about 15Mins in Sun One. We might have to drop the Sun One App Srv and go for Weblogic though we dont want. This same thing is working with about 4MB object in Sun One but takes about 45 Mins to 1 Hour to finish the serialization etc for jndi .Kindly provide some guidance.Thanks in advance.

True. At the end I configured the value as a "server property". The cool thing about configuring the jndi tree is that it is replicated in a cluster.
Obviously the values that I inserted affected all the applications, like the url of our SOA server.

I have added "ht.put(WLContext.REPLICATE_BINDINGS, "false");" to get rid of the conflict error but I what this object to be clustrable and you please let me know how do I make this object clustrable.
I am using quartz schedular.

SAP objects into Webservices

Hello Experts,
Can anybody guide me to explain how to convert the SAP objects into webservices.
For example, convert Leads in SAP to be exposed as webservices.
Thanks,
Vijay

Hello,
Quick answer to find the standard services without J2EE Engine or XI there is a BSP application that can be used to list the Web Services.
http://<host_name>:<port_number>/sap/bc/bsp/sap/WebServiceBrowser/search.html?sap-client=<relevant_client>
See this link: [Generating WSDL in SAP WebAS|http://help.sap.com/saphelp_webas620/helpdata/en/94/f8c8c8e68811d6b2dc00508b5d5211/content.htm]
Detailed answer
Classical way of creating Web services in ABAP stack is easy. If you are familiar with SAP RFC (Remore Function Calls), every RFC enabled Function Module can be "published" as a web service. The trick is the SOAP (runtime) service available since WAS 6.20. See the [Basic Concepts of SAP SOAP runtime|http://help.sap.com/saphelp_webas620/helpdata/en/94/f8c8a2e68811d6b2dc00508b5d5211/content.htm] here.
So, literally you don't have to anything to "generate" web services for "standard objects" - if BAPIs and RFC enabled FMs are those standard objects you are looking for.
To enable the use of Web Services in external tools, a description of the interface must exist in the Web Service Description Language WSDL. - This is common knowledge right?
In the SAP Web AS, you can generate these descriptions using the Web Service Browser, which is a BSP application.
You can access the Web Service Browser using the URL:
http://<host_name>:<port_number>/sap/bc/bsp/sap/WebServiceBrowser/search.html?sap-client=<relevant_client>
Trick to find the <host_name>, <port_number> and <relevant_client>:
You can determine values of host_name and port_number in transaction SMICM (choose GoTo -> Services or Shift - F1.
Hope this is very useful.
