Call Enterprise Bean (or Database) from private Method in Session-Bean

Hi Everybody,
I've a question regarding the possibility to call an dependency injected EJB in an private method of a session bean.
Imagine the following.
@Stateless
public class SomeBean implements SomeLocal{
   @EJB
   private AnotherLocal anotherBean;
   /** Will be called from a web-app via delegate layer */
   @TransactionAttribute(TransactionAttribute.RequiresNew)
   public void someBusisnessMethod(){
       String something = this.getSomeThing();
       //Do more
   private String getSomeThing(){
      return anotherBean.aMethodWhichCallsTheEntityManager();
}I've to refactor code with uses such Call-Hierachy and I want to know whether this is a correct way? Somebody told me that such stuff should not be made, and I quess he told me an explanation, why not to do such stuff, but unfortunally I've forgotten that. Do someone have a suggestion why not to do this? Could it blow the application to hell? Is there any difference to the following code (The way I would have done it)?
@Stateless
public class SomeBean implements SomeLocal{
   @EJB
   private AnotherLocal anotherBean;
    @Resource
    private SessionContext sessionContext;
   /** Will be called from a web-app via delegate layer */
   @TransactionAttribute(TransactionAttribute.RequiresNew)
   public void someBusisnessMethod(){
       SomeLocal self = this.sessionContext.getBusinessObject(SomeLocal.class);
       String something = self.getSomeThingBusinessMethod();
       //Do more
   @TransactionAttribute(TransactionAttribute.Required)
   public String getSomeThingBusinessMethod(){
      return anotherBean.aMethodWhichCallsTheEntityManager();
}

Found the answer by myself....
Here it is if someone might have the same question:

The motivation here is that most EJB implementations work on proxies. You wouldn't be too far off in thinking of it as old-school AOP. The business interface is implemented by the EJB container, quite often via a simple java.lang.reflect.Proxy, and this object is handed to everyone in the system who asks for the ejb via @EJB or JNDI lookup.
The proxy is hooked up to the container and all calls on it go directly to the container who will preform security checks, start/stop/suspend transactions, invoke interceptors, etc. etc. and then finally delegate the call to the bean instance -- and of course do any clean up required due to any exceptions thrown -- then finally hand the return value over through the proxy to the caller.
Calling this.foo() directly, or passing 'this' to a caller so they can make direct calls as well, will skip all of that and the container will be effectively cut out of the picture. The 'getBusinessObject(Class)' method allows the bean instance to essentially get a proxy to itself so it can invoke its own methods and make use of the container management services associated with it -- interceptors, transaction management, security enforcement, etc.

Error while adding a new method to the Session Bean

Hello everyone. I'm using jdev 11g, ejb, jpa & jsf. Everything works fine. But when I try to add a custom method to the Session Bean, I'm having an error.
Here is my steps:
1) I added a new method to SessionBean.java. Something like this:
public void Hello() {
System.out.println("Hello!");
2) Then using Structure palette I exposed this method through Local interface and created data control
3) Finally, I made a command button binded to this method (just droped it from DataControls.dcx to my page)
When I start the page and click the button, I'm having the following error:
Error 500--Internal Server Error

 at oracle.adf.view.rich.component.fragment.ContextSwitchingComponent$1.run(ContextSwitchingComponent.java:70)

Yes, I have binding in the page def. Everything is correct there:
<methodAction id="Hello" RequiresUpdateModel="true" Action="invokeMethod"
MethodName="Hello" IsViewObjectMethod="false"
DataControl="PriceServiceLocal"
InstanceName="PriceServiceLocal.dataProvider"/>
I've droped the method from the Data Controls panel

How to call a private method in a JFrame

I have a Frame which has some properties like its size, bgcolor plus other parameters, as instance variables. There is a button on the Frame with the caption : "set properties". When one clicks on that button, a new frame should appear via which a user can change the values of the parameters of the main Frame (i.e size, bgcolor,..etc). The user would input the new values in the textfields or radio buttons that are on the new frame, and then click a submit button, which has to exist on the same NFrame. How can I do that so that when the submit button is pressed, the parameters values are updated and so is the display view ?
I made it this way : I created 2 classes, the main frame and the new Frame. I made the new Frame an instance variable of the main Frame. When the user clicks the " set properties" button on the main Frame, the new Frame is shown. The user enters new values for some of the parameters and clicks submit. The parameters in the new Frame are updated. UP TO HERE EVERYTHING WENT JUST FINE. Now, there is a private method in the main frame that changes the color, size, ...etc of the main frame according to the values stored in the instance variables color, size,...etc. THE QUESTION IS: How can the new Frame display the changes after the values have been updated ? That is, how can it call the "private" method in the main class?? Should the new class be a child class of the main class to be able to access it's private methods ??

Calling a method in the backing bean when rendering a table

I'm rendering a table that begins with :
<h:dataTable value="#{showRooms.rooms}" var="rowRoom" ...
There are several properties I'm displaying. Some are just displayed as they appear from the database like:
<h:outputText value="#{rowRoom.roomNumber}"/>
However, some I need to translate so they display a more meaningful message to the users. For example, status is stored 'A', or 'NA', but this should display 'Available' or 'Not Available'. To do this, I'm taking an idea I saw in another forum by providing a method to call and translate the text. For example:
public String getDisplayedStatus(String status) {
if (status.equals("A") {
return "Available";
} else {
My problem is how can I invoke a method and pass in the current value of status for that row in the table. I think I need something like this:
<h:outputText value="#{showRooms.getDisplayedStatus(#{rowRoom.roomStatus})"/>
But that doesn't work. I can invoke the getDisplayedStatus method when passing in a hardcoded parameter, but it won't translate the value of both expressions(the method and the method param). How can I achieve this?
Thanks,
Mike

Yes. I've done that and it does work....sort of. It works as long as I refer to it as 'displayStatus'. It looks up the getDisplayStatus and returns a value. The problem is getting the current status value from the object in the List. For example, the 3rd row in the table has either 'A;' or 'NA' for status. I need to know this value in order to do my translation. The way I see it, I either need
1.)a way to call a method on the backing bean and pass the value of status from the current row into the method.
-or-
2.)in getDisplayStatus, I need a way to access the current row's value, perhaps through an expression. This appears to be what you can do in the AbstractPageBean class that all backing beans inherit in Studio Creator. I've seen code in a getter like 'getValue(#{currentRow.status}'), but I don't know how that is done. I looked for the source to AbstractPageBean on the web but couldn't find it - maybe its not open-source.
Anyway, please share if anyone has a solution. I'm sure this has been done before.
Thanks,
Mike

Error while usind Private Method of a global class

Replace TOT_DATA with M2, you do not have any method by name "TOT_DATA" in your code.

How to know the class method behind an enterprise service

Hi,
SAP has provided enterprise services for Room booking in Real Estate module. They are even shipping the complete application for a nominal price. But the standard version is not suitable for our client requirement so they want to develop this application inhouse.
Now my question is: I know the enterprise services used in this application. How to know the implementing methods behind these enterprise services ?
If possible suggest which approach will be a better option for the inhouse development.
1. Webdynpro ABAP and use directly methods behind the enterprise services.
2. Webdynpro ABAP and create client proxy class for the enterprise services.
3. Webdynpro JAVA and use the enterprise services.
4. Using visual composer modelling the application.
Please suggest the best alternative.
Best Regards,
Aleem Mohiuddin.

Hi
They are even shipping the complete application for a nominal price. But the standard version is not suitable for our client requirement so they want to develop this application inhouse.
I assume you are talking about xApps.
How to know the implementing methods behind these enterprise services ?
In sproxy transaction you can search service and then you can see class and method implemented behind that particular service.
1. Webdynpro ABAP and use directly methods behind the enterprise services.
In my opinion not recommended to bypass ES and use method behind it.
2. Webdynpro ABAP and create client proxy class for the enterprise services.
Not sure why you want to create proxy of ES.
3. Webdynpro JAVA and use the enterprise services.
4. Using visual composer modelling the application.
You can use either Webdynpro (ABAP or Java) or VC to model your application which consume ES in backend. Both options are good, you can chose Java or ABAP flavor of dynpro based on skill available in team. VC is very effective in rapid modelling and can be used in protyping or in development of complete application.

Creation of a static class with private methods

I'm new to java programming and am working on a project where I need to have a static class that does a postage calculation that must contain 2 private methods, one for first class and one for priority mail.

Can we call a method in stateless session bean ?

Can we call a method in stateless session bean in onMessage method?

Hi,
The purpose of service locator is to abstract the lookup of the server side services like ejb and DSNs. It should be a normal java class but as such there is no such restriction. You can have a look at the service locator patter at the j2ee blue prints.

Update object returned by a business method in stateful session bean

I have a business method in stateful session Bean returning an Object "myObject getObject()". This object can be modified by the client.
Is it necessary at the end to notify the bean about the changes with some kind of business method "setObject(Object myObject)"? or
the client and the bean have the same reference to the object and it isn't necessary?
Thanks

When an EJB returns a value, it is serialised across the wire and is effectively lost to the EJB. Any changes to the returned object by the client, will have to be notified by a call on the EJB, as in your post.

Private methods Importing parameter cannot be changed error

Hi Guys,
I have this scenario where I have a private method inside a class which is having an error "Field SAPMF02K cannot be changed".
here is the code for the private method call.
    call method create_bdc_dynpro
         importing IM_PROGRAM = 'SAPMF02K'
                    IM_DYNPRO = '0100'.
code of the method
data: wa_bdcdata type bdcdata.
CLEAR wa_bdcdata.
wa_bdcdata-program = im_program.
wa_bdcdata-dynpro = im_dynpro.
wa_bdcdata-dynbegin = at_true.
APPEND wa_bdcdata to at_bdcdata.
Hope you can help
Thanks!

Howdy,
I think you have your importing/exporting the wrong way round.
The method call should be:
call method create_bdc_dynpro
exporting IM_PROGRAM = 'SAPMF02K'
IM_DYNPRO = '0100'.
And of course in the method definition they should be importing parameters.
Cheers
Alex

Extending classes with private methods?

my understanding of extending classes is that you gain all the functions and methods of that class thus You could over ride any one of them. How ever I am confused on weather or not you inherit and can over ride private methods of the class you are extending or if you have to have all methods public in an extended class.
hope that makes sense, an example can bee seen bellow.
package
     public class Class1
          public function apples():void
               //some code
          private fnctuin bananas():void
               //more code
package
     public class Class2 extends Class 1
          override public function apples():void
               //i changed code
          //can I over ride bananas?

you can only override methods that would be inherited. a private method won't be inherited:

Is this possible?

Damir, of course you can call a private method of a class, if this class has made you a friend with the syntax element FRIENDS (available since Release 6.10). Here is a syntactically correct example, when my_method is a private class method:
REPORT test.
CLASS mytest DEFINITION FOR TESTING.
PRIVATE SECTION.
    METHODS test FOR TESTING.
ENDCLASS.
CLASS myclass DEFINITION FRIENDS mytest.
PUBLIC SECTION.
    CLASS-METHODS my_method.
ENDCLASS.
CLASS myclass IMPLEMENTATION.
METHOD my_method.
ENDMETHOD.
ENDCLASS.
CLASS mytest IMPLEMENTATION.
METHOD test.
    CALL METHOD myclass=>my_method.
ENDMETHOD.
ENDCLASS.
If my_method is not a class method, then you need to create an object of the class first, whose methods you want to test.
Kind regards,

UnusedPrivateMethod - bug when using static private method?

Hi,
I get the following violation:UnusedPrivateMethod. This private method (createDefaultSolidColors) does not seem to be used.
For the foloowing code snippet:
private static const defaultSolidColors:Array = createDefaultSolidColors();
private static function createDefaultSolidColors():Array {
     var _a:Array = new Array();
     for each (var color:uint in defaultColors) {          _a.push(
new SolidColor(color, 0.8));     }
     return _a;}
Why is it a violation? the function is used by the defaultSolidColors property.
Is it a bug or am I missing something?
Thanks,
-ilan

This is a known issue, which has been fixed on trunk.
The fix will be in the next release:
