How to expose and call AM methods from plain java (testability etc)?

Hello,
my project is just starting out with the OA Framework. We just encountered our first hurdle - I hope someone here can help out or at least point me in the right direction. None of this stuff seems to be explicitly mentioned in the standard OAF documentation.
This is the situation: We need to call the logic in our Application Modules directly. Two reasons for this:
- We need to expose methods in the AM as web services
- We really want to create unit\integration tests (probably JUnit) and set up some sort of continous integration environment (Cruisecontrol or similar).
Now, how do we go about this? I see that controller code usually does something a la this:
OAApplicationModule am = pageContext.getApplicationModule(webBean);
This doesn't seem viable for plain javacode, since there is no pageContext or web beans in that situation.
Now, I allready tried the most naive approach (tried it in the OAF Tutorial):
EmployeeAMImpl employeeAMImpl = new EmployeeAMImpl();
This of course doesn't work, since none of the VO\EO seem to be instantiated, db connection is probably not set up etc.
The third approach is the one I found in the javadoc for OAApplicationModuleImpl:
// load some basic properties
Properties properties = loadProperties();
javax.naming.Context ic = new InitialContext(properties);
// 'defName' is the JNDI name for the application module
// definition from which the root Application Module is to be created
String defName = "abc.xyz.SampleApplicationModule";
oracle.jbo.ApplicationModuleHome home = ic.lookup(defName);
return home.create();
This seems more promising this far, however I need help with the following two questions:
1: Do I really need to go through JNDI to access my AMs from plain javacode (JUnit tests, webservices etc)? If not, how do I then instantiate AMs, complete with EOs, VOs etc?
2: If I do need to go through JNDI: what is the easiest way to register and subsequently call my AMs and their logic\context, particularly for usage from web services and testing frameworks (JUnit etc)?
I'm kinda stumped here, guys. How have you solved this, if you haven't then how would you go about doing it?

How to call the method from the java bean and pass it to JSP textbox

i'm quite new to java thats why i'm asking how to call a method in the java bean file and pass it to the JSP textbox. My projects are communicating JSP with C#. i had successfully created a C# client bean file for JSP. The whole process is to type something on the server(C# programming) and it would appear in the textbox.

your question doesn't provide much informartion. provide some other information and coding so that we could tell exactly what you are looking for?

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.

How to create and call a COM component in Java

Hi All,
can you suggest how to create and call a COM component..or if have any sample simple application can you send it to me...i will try to develop my project.
actually i am configuring a OCR Engine using SDK which is in VB .Net when i contacted their support they told that if i have any sample COM based component Project they will help me...
So please can you help in this.
Thanks in advance.

As said by my fellow posters Java Devolopment Environment (Except Microsoft implementation of JVM,this is no longer supported by MS themseleves) does not provide an built-in support to serve this cause.
If you are looking to devolop a custom based solution the below is a good place to start with where end user is talking about Java <=> JNI <=> Native <=> COM connectivity.

Calling a method from another Java file.

I think I'm doing this right, but I'm obviously going wrong somewhere.
In order to not have one big long java file, I've created one main one to execute the program, and another to do some of the functions. I'm using eclipse, btw.
In the main file, I have
currentTB = getActiveTB(playerArea);If it works, it should get send the player area variable to the getActiveTB method, and store the value it returns in the currentTB variable, right?
In the other file, I have;
package scenes;
public class sceneIndex {
     private TerrainBlock getActiveTB(String areaCode) {
          TerrainBlock tBlock = new TerrainBlock();
                 **DOES STUFF**
          return tBlock;
}I have it set up so the second file is in the source folder "resources" and the package "scenes." The problem is I'm not calling it properly. I'm missing something simple, I think. The only error I'm getting is;
The method getActiveTB(String) is undefined...
Where am I screwing up?
EDIT: Yeah, I'm a rookie here trying to figure it out on my own. My computer science courses, so far, conveniently all consist of just one big java file. Easier to write, sure, but not very efficient/organized.

How to call a method from class interface

Hi ,
I want to call a method from a 'class interface' in a BADI .
Class Interface -- /SAPSRM/CL_PDO_DO_BASE
Method -- /SAPSRM/IF_PDO_DO_PARTNER_BASE~UPDATE_ITEM_PARTNERS
Please let me know how can I call this method in my BADI.
Thanks-

Hi Harmeet,
Follow these simple steps.
1. Create an instance of class interface /SAPSRM/CL_PDO_DO_BASE if method /SAPSRM/IF_PDO_DO_PARTNER_BASE~UPDATE_ITEM_PARTNERS is instance method and
call instance -> /SAPSRM/IF_PDO_DO_PARTNER_BASE~UPDATE_ITEM_PARTNERS
2.if method /SAPSRM/IF_PDO_DO_PARTNER_BASEUPDATE_ITEM_PARTNERS is static method ,call directly using class interface like /SAPSRM/CL_PDO_DO_BASE=> /SAPSRM/IF_PDO_DO_PARTNER_BASEUPDATE_ITEM_PARTNERS.
If you feel any dificulty in declaring instances and call methods,
Goto EDIT-> Pattern ->ABAP Object Patterns, Give class name , instance name and method, you got the required code.
Thanks,
Prasad.

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?

operationBinding.getParamsMap().put("userName",userNameVal);
operationBinding.getParamsMap().put("password",passwordVal);
operationBinding.execute();
i am getting operation verifyLogin not found error.Please suggest me something to do.

Hi vlsn,
Can you try with the below code
// in your backing bean
OperationBinding operation = bindings.getOperationBinding("verifyLogin");
//Put your both parameters here
operation.getParamsMap().put("parameter_name1", parameterValue1);
operation.getParamsMap().put("parameter_name2", parameterValue2);
operation.execute();
if (operation.getResult() != null) {
Boolean result = (Boolean) operation.getResult();
and share the result.
regards,
Rajan

Calling a method from a super class

Hello, I'm trying to write a program that will call a method from a super class. This program is the test program, so should i include extends in the class declaration? Also, what code is needed for the call? Just to make things clear the program includes three different types of object classes and one abstract superclass and the test program which is what im having problems with. I try to use the test program to calculate somthing for each of them using the abstract method in the superclass, but its overridden for each of the three object classes. Now to call this function what syntax should I include? the function returns a double. Thanks.

Well, this sort of depends on how the methods are overridden.
public class SuperFoo {
public void foo() {
     //do something;
public void bar(){
     //do something
public class SubFoo extends SuperFoo {
   public void foo() {
      //do something different that overrides foo()
   public void baz() {
      bar(); //calls superclass method
      foo(); //calls method in this (sub) class
      super.foo(); //calls method in superclass
}However, if you have a superclass with an abstract method, then all the subclasses implement that same method with a relevant implementation. Since the parent method is abstract, you can't make a call to it (it contains no implementation, right?).

Calling a method from another class or accessing a component from another

Hi all
im trying to make a find/replace dialog box
my main application form has a jtextpane and when i open up the find and replace dialog box it has two textboxes (find and replace)
now i have the code to do the finding on my jtextpane but how do i call that code to do the find method?
I have tried having the code in my main application class but then how do i call that method from my dialog box class?
ive also tried having the code in my dialog box class, but then how to i tell it to work on my jtextpane which is in my main ap class?

well if someone had been nice enough to provide me
with a tutorial i wouldnt have gotten into this
muddle, no need to be rude is there!I'm not rude. And you also wouldn't have gotten into the muddle if you searched yourself. This site provides many very good tutorials about all kinds of stuff.
http://java.sun.com/docs/books/tutorial/java/javaOO/classes.htmlAmong other things, it mentions that "static" defines everything that belongs to a class, as opposed to an object.
