Modify adf component from java using binding

Hi,
I'm using jdeveloper 11.1.1.6.0
I am making an application to learn how to "Binding". To do this, I followed the example " [Binding a JSF Page to a Managed Bean|http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_33/jdtut_11r2_33.html] "
Now, what I'm trying to do is access the entire object. To do this, in the "Binding" of "login" write:
ManagedBean -> Persondata
Property -> loginObject
And in the "Binding" from "email" write:
ManagedBean -> Persondata
Property -> emailObject
So in the java class attributes are created Persondata "loginObject" and "emailObject" type "RichInputText".
If I change the method code "commandButton_action"
     commandButton_action public object () {
         System.out.println ("personData.getId () ->" + personData.getId());
         System.out.println ("emailObject.getId () ->" + emailObject.getId());
return null;
The output is:
personData.getId () -> null
emailObject.getId () -> null
What am I doing wrong?
I´ve seen this page but I'm not sure what I have to do....
Thanks a lot,

oceano,
you are using the wrong tutorial. The one you use is for JDev 11.1.2.x and not for 11.1.1.x which you are using. Im not sure it make any difference but just want to mention it. The right tutorial for your version is here http://www.oracle.com/technetwork/developer-tools/jdev/ccset33-all-089829.html
Can you post the code of your page (and please format it when posting it here -> FAQ)?
And the code of the Bean?
Do you have defined the getId() method in the bean?

Opening ADF page from java script

I am trying to use window.open(url, winName) to open an ADF page from java script.
I have set the same winName but when i call the window.open method every time it opens up a new window.
The code is as below:
<html>
<head>
</head>
<body>
<script>
function openwin() {
window.open("about:blank", "winDocPrint", "width=800,height=600,location=no");
</script>
<form action="http://127.0.0.1:7101/RegionRefresh-ViewController-context-root/faces/EnterAndDisplay?_afrLoop=3611588465186&_afrWindowMode=0&_adf.ctrl-state=zoaas2mc3_4" target="winDocPrint" onsubmit="openwin">
<input type="submit" value="Print Comments Call ADF">
</form>
</body>
</html>
when I click the button first time, it opens a new window, and keeps opening a new windows on clicking the button again.
I want it to use the same window that was opened first time.
Any help would be appreciated.
Thanks,
Sandeep M.

Hi,
you need to keep the window handle reference so you can access the same window

How to Create adf table from java bean

Hi,
How to Create adf table from java class (Not from ADF BC).
Thanks
Satya

@vlsn -- you have to follow what shay said.
Do the following in Model layer ::
create a table property java class with your columns setters and getters like :
*public class gridProps {*
private int sno;
private String orderNum;
*public void setSno(int sno) {*
this.sno = sno;
*public int getSno() {*
return sno;
*public void setOrderNum(String orderNum) {*
this.orderNum = orderNum;
*public String getOrderNum() {*
return orderNum;
Create another table java class which will populate the values to your column values and return the collection :
*public class gridPopulate {*
private List<gridProps> gridValues ;
*public List<gridProps> setToGrid(ArrayList<ArrayList> valuesToSet) {*
*if (valuesToSet == null) {*
return gridValues;
gridValues = new ArrayList<gridProps>();
if(btnValue.equals("completeBtn"))
return gridValues;
for(ArrayList<String> tempArr:valuesToSet)
gridProps gp = new gridProps();
gp.setSno(Integer.valueOf(tempArr.get(0)));
gp.setOrderNum(tempArr.get(1));
return gridValues;
Right click gridPopulate class and create this as data control.This class will be seen in Data control list.Under this data control,Drag the grid property collection(created earlier) to your page.Then execute your binding(gridPopulate) according to your logic.

Duration of an Abap Function call from Java using Jco3

Hi guys!
I would like to use this discussion to get some refernces of the duration Timespan of an RFC call from Java to SAP. At the moment, i need at last about 200ms to call the Abap function. I'm just using one simple import and export parameter (so no deep structures). I think that the reason for my poor performance is, that the Java Tool and the SAP instance are not in the same network. So, i hope some of you have some data, how fast an RFC call from Java using Jco can be executed.
greetings, Hannes

Hi Hannes,
I think you have already got the answer to your question - the network set-up you have is probably the bottleneck. Whenever I've worked with Java <-> ABAP and they are in the same network, I've had no performance problems at all.
Does your RFC contain any complex logic or business processes? Are you able to try and call something that does nothing, say it just accepts an input string and returns it straight away as an export. Do you have any scope for testing with your Java tool on the same network as the SAP system?
Cheers,
G.

Calling a method in the Custom ADF component from JSF page

HI.
I have created some custom compoents by extending the core ADF Components. Like i have a ComboBoxDefault component with it's ComboBoxDefaultTag.java and Controls.tld file.
Now my requirement is i want to bind my label to this component from the JSF page. like
<fwcontrols:label binding="#{listComponents.comboBoxDefaultLabel}" id="label1"/>
<fwcontrols:comboBoxDefault binding="#{listComponents.cmbLocales}"
value="en_GB" id="comboBoxDefault" autoSubmit="true" label="label1">
<f:selectItems value="#{listComponents.locales}"/>
</fwcontrols:comboBoxDefault>
In my JSF page the label will have an id, and that id will be specified in the label tag of the component.
In Tag.java file i have overrided the setProperty(FacesBean facesBean). In this method i have bind all my properties. In core JSF the setProperty method is provided with the UIComponent parameter, so i can call my method in component also. Which is not in case of ADF Faces.
My main point is how i can call my method setLabel() which is in ComboBoxDefault.java so that i can set the label.
Thanks in Advance.

Thanks for all your replies. I want this kind of a functionality because Im trying to invove a DC (Child DC) from a Parent DC such that the Child DC's view is displayed onto the view container of the Parent DC. I have embedded using 'interface view of a component instance' in the Parent Window and am able to create the component and set usage though the onPlugDefault of the Child View.
But I observe that when i make a call from the parent, the flow is like this:
1. The wdDoInit of the Child Component Controller gets triggered first.
2. Then the wdDoInit of the Child's <b>VIEW</b> gets triggered
3. and <b>THEN</b> the onPlugDefault of the Child Component Interface View
What I had actually wanted was to Fire onPlugDefault where Im calling a method LoadData(), after which the Child DC's view must be triggered so it can display the fetched data.
What is actually happening is the view gets displayed, but no data is displayed in the view.
Right now I have just given a work around where Im triggering <b>LoadData()</b> of the <b>COmponent COntroller</b> from the <b>wdDoInit</b> of the <b>VIEW</b>.
Is there a better way to do this? I find it strange that I have to load the Data from the view.
Thanks

How i can set the selected item of a dropDown component from java code

Hi
Thank you for reading my post
How i can set the slected item of a DropDown component from backing beans java code ?
it is binded with a database , so one field determine its display and one other field determine its value , I want to set the selected item of this combobox
In back code i have both value and display values to use them .
can some one give me some help ?
Thanks ,

See code sample 3 at http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/helloweb.html
See also, the selection components row in the table under http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/helloweb.html
It says
One way to preselect items is to call setSelectedValue(Object[]) or setSelectedValue(Object) from the prerender() method. You pass in the return values of the items that you want preselected. Be sure to verify that getSelected() returns null before setting the default options, or you will overwrite the user's selections on a post-back.

Cross-component: Call method of using component from within used component?

Hi,
I began diving into cross-component programming.
Meanwhile after having digged into some scenarios some questions came up to my mind that I am not able to answer myself. I would appreciate your help here!
Say we have to components. Comp A uses Comp B (hence, B is a component usage in A)
1) How to make them communicate not on a data level (via context binding) but on a process level, thus...
a) can I call A's method from within B? How is the approach on a general level? - as B can be used from totally different components (like A, A1, A2 ...)
b) perhaps the only way to do this is by firing events? If so, how can I react in A when an event in B (marked as interface event) gets fired? As it seems they do not get registered within A directly...
I guess the question seems to be a bit tricky. Nevertheless, I think there will be plenty of you out there who used to asked them the same questions before and came up with an approach. Would be nice to hear from you.
Best wishes,
Marc @sap1

Hi,
thanks for your reply!
Indeed, I think the nature of WDA would be just to somehow map the context from the used component to the other back and forth.
Nevertheless, what if I would like to invoke a method of the using component from inside the used component.
One sample for this requirement could be e.g.:
Component B offers a tree item and a send/verify button.
Component A uses B and has some restraints regarding what the selection should look like.
The user taps the button in B (at runtime in the view container of A), the context gets updated in A and B and in Component A the verifyWithOwnConstraints() method gets called (through B).
Thanks again,
Marc

Calling a VB Com component from Java

Hi,
I wish to call some legacy VB 6 COM dlls from some new Java code I am writing. I was looking (just read quickly haven't tried the examples yet) at the ActiveX Bridge documentation and get the impression that it only goes one way -i.e. make Java into an ActiveX Component to be used from VB, whereas I wish to call VB from Java.
Have I missed something or is this not the way to go to get to the legacy code?
The legacy code also has an MIDL file. Ideally, I would love to just be able to access that from Java, but I can't find any (non-Microsoft VJ++ based) tools to help with either converting MIDL to IDL so I can use Sun's idlj.exe or just converting the MIDL to Java.
Any pointers/tips on any of this would be appreciated.
Thanks,
Cheryl

I looked at Jacob, but didn't get far either.
Right now I'm looking at Jawin -
http://jawinproject.sourceforge.net/jawin.html. Not
making a lot of headway yet.
IDL is OMG's IDL (Interface Definition Language) -
http://www.omg.org/gettingstarted/omg_idl.htm.
MIDL is Microsoft's version of IDL for COM - I believe
it uses IDL., but can't seem to find a conversion
tool.
idlj.exe is in the bin directory of whatever JDK you
have loaded. This tool will convert OMG IDL into Java.
Good luck to you.Hi,
I am facing a similar problem. I need to access a vb dll methods. I took and look at jawin and installed it.

I wan to i visible/invisble Panel(Adf Component) on UI using ADS?

HI,
Following is my requirement
I am having one panel which should be visible/invisible on UI based on event coming from Web services.
I am consuming one web services which is sending me update which i suppose to read at specified interval.
if there is any update from web services then i suppose to visible/invisible Pane(ADF component)l on UI.
Active Data Service can be useful for this requirement?
If Yes,
Do i need to create Active Data Proxy for this?
Your suggestion will be helpful.
- Deepak Parmar

Frank Nimphius,
Thanks for your quick reply. :)
This is really good article which has provided one good way how to trigger event from client whenever we get update from server.
but i am still having some questions:
1) based on post you have provided, if i can able to trigger event from client then do i need to use ADS anymore?
2) Do you have source code for the same? , I want to see how ADS is playing role here.
3) if i am getting update from web services then do i need to create Active Data Proxy?
Regards,
Deepak

To read a DLL from java using JNI

Hi,
I had some DLL files (VB 5.0) which are providing interfaces. Is there any chance of accessing that using java (JNI). Also is there any De - Compiler available so that I can get the source code of the DLL file.
Regards,
Hari.

Hola Hari
To make a dll loadable through JNI, the interface
inside
the dll must be implemented the JNI way. Also a COM
interface does not help.
I would reccomend a certain product to automatise the
JNI interfacing process, but that would
require that you have the sourcecode of the dll
available.
But one thing you can do is to write a wrapper that
contains the dll classes and is implemented the JNI
way.
More precisely you write an interface wrapper in c/c++
that matches the methods of the dll and does use JNI
methods. Now inside that c++ wrapper you load the dll
and forward the calls from java to c++ vice versa.
Download the demo version of CENTRO.java here:
www.ablon.de
Bye, nilsHi Nils,
Thank you for your suggestion. Im new to JNI.
That dll's are in Visual Basic. I don't have the source code of the dll file. I got the interfaces available in the dll file from a Visual Basic program which make use of the dll file(which we are talking about). As I know only the method signatures in the interfaces(dll file), I request you to kindly provide me some help to wrap it in C/C++ program.
Thanks in advance.
Regards,
Hari.

Calling BDC from Java using JCO

Hello Everyone,
Is it possible to call a BDC from Java program using JCO ?

Are you serious with that question? Did you try to build the web service client before? Because this is exactly the same. Try to find "building web service clients" instead "Calling BPEL from java". By default (probably) every BPEL process has both WSIF and SOAP end points, just use correct WSDL address.

Calling package from java using JNDI properties

Hi there,
I have created an interface to transfer data from oracle to JMS XML Queue. It is inside a package and have generated a scenario.
The scenario works well when executed from the ODI designer. When I execute it from java it throws an error. The error is
java.sql.SQLException: Cannot load connection class because of underlying exception: 'javax.jms.JMSException: Cannot create the initial JNDI context
Is there any ways to set the JNDI properties, (any set methods for ODIConnection object)
Cheers

Executing DLLs from Java using JNI vs Runtime.exec()

I am trying to understand the best way to execute a dll using java. The dll I am testing with takes a few input parameter. If I use JNI with System.loadLibrary("dll"); what do I need to do to pass the arguements in as well? Can I just add the arguements in the java code like private int xyz = "value"; and expect that the dll will accept them or is there special definitions I have to set up in the dll to make it work?
Alternatively I was looking at using Runtime to execute the dll by using Runtime.exec("dll param1 param2",env,filePath); Does anyone know if there are drawback to doing it this way vs. using JNI or is this just as efficient? Any help would be appreciated.

You seem to be confused...
"execute a dll using java"
Unless I'm mistaken, a dll is not executable. A dll is a library of code. This code has (hopefully) some well-defined entry points (declared in a header file somewhere) which you must call in a C/C++ file. The arguments you pass to the dll will come from java through JNI.
As far as your understanding of this entire process, it is obviously confused beyond the scope of a simple reply. I recommend you read the examples and ALL of the documentation available here:
http://java.sun.com/docs/books/tutorial/native1.1/index.html
When you get the/an example running (or just set up to run) then post your code and comments here for more help.

Send Datetime2 value to a SQL Procedure from Java using Hibernate

Hi All,
I Have a Procedure which takes a parameter of type datetime2.
The procedure is called from Java Hibernate.
How can I Pass datetime2 value to SQL procedure from Java?
Thanks in advance,

You may define a global empty array in some package. Then you can do:
SQL> CREATE OR REPLACE PACKAGE pkg
AS
   g_empty   DBMS_SQL.varchar2_table;
END pkg;
Package created.
SQL> CREATE OR REPLACE PROCEDURE p (
   p_tuids   IN   DBMS_SQL.varchar2_table "DEFAULT pkg.g_empty"
AS
BEGIN
   NULL;
END p;
Procedure created.
SQL> BEGIN
   p ();
END;
