ADF: is it possible to call bean methods from a DataForwardAction?

Hi,
i have created an ADF data control from bean and I have some values bound and populated in a page. As part of the Action class i would like to execute one of the methods in the bean. Is this possible or am i taking the wrong approach?
regards,
Brenden

Yes, there are a few ways of doing it, please see...

Is it possible to call a package from DB in ADF?

Hi,
I am using Jdev 10.1.3.3 with ADF. I want to call a package from
my DB from jdev. Is it possible with ADF? Please let me know.
Thanks,
Venki

Hi,
This is my code to call the package.
String amDef = "model.service.DAFService";
String config = "DAFServiceLocal";
ApplicationModule am =
Configuration.createRootApplicationModule(amDef, config);
     CallableStatement cstmt = null;
     String stmt = "begin call CP_DAF_PKG.DAF_PROCESS(?,?,?,?,?,?,?,?,?); end; ";
     cstmt = getDBTransaction().createCallableStatement(stmt,0);
But in this case, I am getting
oracle.jbo.InvalidOwnerException: JBO-25301: Application module is not a root app module but has no parent
I understand the reason for this error. I need to call the
createcallableStatement from the application module that I have above.
Something like am. (call the package)
But not sure about any method which does that..
Please let me know if you know the way to solve it.
Thanks,

How to call backing bean method from java script

i am getting operation verifyLogin not found error.Please suggest me something to do.
Thanks

Hi vlsn,
Can you try with the below code
// in your backing bean

You can make use of the constructor of the backing bean or the @PostConstruct annotation if you want to use managed properties.
You may get some ideas out of this: [http://balusc.blogspot.com/2006/06/communication-in-jsf.html].

EJB 3.1 @Asynchronous and calling other methods from within

Hey all,
I am helping a friend set up a test framework, and I've turned him on to using JEE6 for the task. I am decently familiar with entity beans, session beans, and such. One of the new features is @Asynchronous, allowing a method to be ran on a separate thread. The test framework generally needs to spawn potentially 1000's of threads to simulate multiple users at once. Originally I was doing this using the Executor classes, but I've since learned that for some reason, spawning your own threads within a JEE container is "not allowed" or bad to do. I honestly don't quite know why this is.. from what I've read the main concern is that the container maintains threads and your own threads could mess up the container somehow. I can only guess that this might be possible if your threads use the container services in some way.. but if anyone could enlighten me on the details as to why this is bad, that would be great.
None the less, EJB 3.1 adds the async capability and I am now looking to use this. From my servlet I use @EJB to access the session bean, and call an async method. My servlet returns right away as it should. From the async method I do some work and using an entity bean store results, so I don't need to return a Future object. In fact, my ejb then makes an HttpClient call to another servlet to notify it that the result is ready.
My main question though, is if it's ok to call other methods from the async method that are not declared @Asynchronous. I presume it is ok, as the @Asynchronous just enables the container to spawn a thread to execute that method in. But I can't dig up any limitations on the code within an async method.. whether or not it has restrictions on the container services, is there anything wrong with using HttpClient to make a request from the method.. and making calls to helper methods within the bean that are not async.
Thanks.

Yes since the EE spec delegated thread management to conatiners, the container might assume that some info is available in the thread context that you may not have made available to your threads.
Also threading is a technical implementation detail and the drive with the EE spec is that you should concentrate on business requirements and let the container do the plumbing part.
If you were managing your own threads spawned from EJBs, you'd have to be managing your EJBs' lifecycle as well. This would just add to more plumbing code by the developer and typically requires writting platform specific routines which the containers already do anyway.

Thanks.If you want to be asynchronous without caring about a return value then just use MDBs.
The async methods have no restrictions on container services and there is nothing wrong with calling other non async methods. Once the async method is reached those annotations don't matter anyway (unless if you call thhose methods from a new reference of the EJB that you look up) as they only make sense in a client context.
Why do you need to make the call to the servlet from the EJB? Makes it difficult to know who is the client here. Better use the Future objects and let the initial caller delegate to the other client components as needed.

Calling a method from another file

This is pretty basic stuff but i can't seem to get it right. I am calling a method from another file. The other file IS located in the same folder BUT when i compile i get errors
"cannot find symbol" <===referring to limit and sieve i believe.
The method name is "sieve" the file name is "PrimeSieve2008" and "limit" is the variable in brackets in the real method.
     public static void main (String [] args) {
final int [] PRIMES;
int sieve = PrimeSieve2008.sieve(limit);
     PRIMES = sieve(getValidInt());
          for (int j = 0; j<PRIMES.length; j++) {
               System.out.println("Prime[" + j + "] = " + PRIMES[j]);
Is "int sieve = PrimeSieve2008.sieve(limit)" the wrong way to call a file?
Thanks a million,
Alex

I really am clueless here.in this one you are passing in limit.
in the other one you are getting limit from somewhere outside of main.

Calling ABAP method from JCo

Hi All,
I need to invoke a static method of an ABAP class from JCo. Is this possible? I am new to JCo. Any help in this regard is highly appreciated.
Thanks,
Praneeth

Hello Praneeth,
i'm not sure about calling ABAP class method from JCo directly, but there is a possibility to call function module from SAP R3. And the shortest way to do so is described in Re: Accessing SAP backend from j2ee without entrprise portal thread, answered by me.
I guess there is no problem to call an class method from an function module.
Please consider rewording points if helpfull.

How to call View Method from ComponentController ?

Hallo Experts,
Is there a possibility to call a method of View(Controler) from the ComponentController ? Component is still the same.
Greetings
Wojciech

Hi Wojciech,
as already said by Gopi, the methods of the view should not be called outside the view! Of course you could store a reference to the view inside the comp_controller, but the right way is to inform the the views in case of changes! Just use events to notify view about changes and trigger changes inside the event-handler (which are inside the views).
Best regards,
Stefan

Call C# method from javascript in WebView and retrieve the return value

The issue I am facing is the following :
I want to call a C# method from the javascript in my WebView and get the result of this call in my javascript.
In an WPF Desktop application, it would not be an issue because a WebBrowser
(the equivalent of a webView) has a property ObjectForScripting to which we can assign a C# object containg the methods we want to call from the javascript.
In an Windows Store Application, it is slightly different because the WebView
only contains an event ScriptNotify to which we can subscribe like in the example below :
void MainPage_Loaded(object sender, RoutedEventArgs e)
this.webView.ScriptNotify += webView_ScriptNotify;
When the event ScriptNotify is raised by calling window.external.notify(parameter), the method webView_ScriptNotify is called with the parameter sent by the javascript :
function CallCSharp() {
var returnValue;
window.external.notify(parameter);
return returnValue;
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = DoSomerthing(parameter);
The issue is that the javascript only raise the event and doesn't wait for a return value or even for the end of the execution of webView_ScriptNotify().
A solution to this issue would be call a javascript function from the webView_ScriptNotify() to store the return value in a variable in the javascript and retrieve it after.
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = ReturnResult();
await this.webView.InvokeScriptAsync("CSharpCallResult", new string[] { result });
var result;
function CallCSharp() {
window.external.notify(parameter);
return result;
function CSharpCallResult(parameter){
result = parameter;
However this does not work correctly because the call to the CSharpResult function from the C# happens after the javascript has finished to execute the CallCSharp function. Indeed the
window.external.notify does not wait for the C# to finish to execute.
Do you have any solution to solve this issue ? It is quite strange that in a Window Store App it is not possible to get the return value of a call to a C# method from the javascript whereas it is not an issue in a WPF application.

I am not very familiar with the completion pattern and I could not find many things about it on Google, what is the principle? Unfortunately your solution of splitting my JS function does not work in my case. In my example my CallCSharp
function is called by another function which provides the parameter and needs the return value to directly use it. This function which called
CallCSharp will always execute before an InvokeScriptAsync call a second function. Furthermore, the content of my WebView is used in a cross platforms context so actually my
CallCSharp function more look like the code below.
function CallCSharp() {
if (isAndroid()) {
//mechanism to call C# method from js in Android
//return the result of call to C# method
} else if (isWindowsStoreApp()) {
window.external.notify(parameter);
// should return the result of call to C# method
} else {
In android, the mechanism in the webView allows to return the value of the call to a C# method, in a WPF application also. But I can't figure why for a Windows Store App we don't have this possibility.

How to Call C++ Method from Java

I need to call C++ method from Java.
I have gone through the JNI tuorial , but was not able to pin point things.
I read that :
You have to write JNI c functions which then call your C++ member functions.You need to write a JNI function which will call new on your C++ class.
Now i have java class :
Java Code JavaClass.java ---->
class JavaClass{
public native void nativeMethod();
    static
        System.loadLibrary("NativeCppCode");
     private void callCppMethod()
          //call C++ method
                JavaClass jvc = new JavaClass();
                jvc.nativeMethod()
}Cpp Code:
NativeCppCode.h---->
class NativeCppCode
public:
    getValue();
    setValue();
private:
   int a;
JNIEXPORT void JNICALL Java_JavaClass_nativeMethod(JNIEnv *env
               ,jobject obj);NativeCppCode.C---->
NativeCppCode::getValue()
   return a;
NativeCppCode::setValue()
   a = 1;
JNIEXPORT void JNICALL Java_JavaClass_nativeMethod(JNIEnv *env
               ,jobject obj)
NativeCppCode* nativeInstabce = new NativeCppCode();
NativeCppCode.setValue();
}Is this the correct way to do it.
Any suggestion would be a great help to me

tryit wrote:

JNI uses C methods.
Is this the correct way to do it.Same way you would do it in any C/C++ method (not java)
       MyClass* p = ....
       p->doit();
Common idiom for the pointer in the above is to pass it back and forth to your java code as a java long. You cast it it and from your class pointer. Provide an explicit java method to free it when done. Besides providing the explicit method also implement a finalizer to free it as well (however that is a fail safe and should not be relied upon.)

How do you call a method from another class without extending as a parent?

How do you call a method from another class without extending it as a parent? Is this possible?

Why don't you just create an instance of the class?
Car c = new Car();
c.drive("fast");The drive method is in the car class, but as long as the method is public, you can use it anywhere.
Is that what you were asking or am I totally misunderstanding your question?

Calling parent method from within child object

Hello,
A quick question! Is it possible to call a method in a parent object from within a child object.By child object I mean an object that was instantiated within the parent object.
Thanks.

A quick question! Is it possible to call a method in a
parent object from within a child object.By child
object I mean an object that was instantiated within
the parent object.Since you are using ambiguous terminology, it would be much better if you provided a small sample of your code to avoid confusion. I am guessing that you are actually talking about an inner class when you say child class.
If that is correct, then you can do something like this:
class Parent {
void foo() {}
void bar() {}
class Child {
    void foo() {}
    void test() {
      bar(); // No conflicts, just call the Parent method
      Parent.this.foo(); // Use explicit qualification to avoid conflicts.
