Event handler implementation
Hi All,
My requirement is as follows:
In my OPA interview screen, I have to enter the account number and clicks a button(It can be submit button). It will fetch all the values related with the policy number using a webservice call and fill in the corresponding fields like user name, account type, bank details etc. (Other details can be in the next page or the same page itself)
I am able fetch the details on ‘load’ event by calling the webservice from the load method in dataadapter plugin. But I am not sure how to do the search and get as above.
Any quick help is very much appreciated.
Best Regards,
Remya
Sounds like you need to handle the BeforeSubmitDataEvent to look up the details for the account number, and add them into the session.

Help needed in implementing validation event handler in OIM 11g
Hello experts,
I am trying to set username policy by implementing a validation event handler in OIM 11.1.1.5.
Following are the steps followed
1. Import metadata
Created a file called Eventhandler.xml as below and imported using weblogicImportmetadata.sh
<?xml version='1.0' encoding='UTF-8'?>
<eventhandlers xmlns="http://www.oracle.com/schema/oim/platform/kernel" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.oracle.com/schema/oim/platform/kernel orchestration-handlers.xsd">
<validation-handler class="test.iam.eventhandlers.CustomValidationEventHandler" entity-type="User" operation="CREATE" name="CustomValidationEventHandler" order="1000" sync="TRUE"/>
</eventhandlers>
2. Register plugin
plugin.xml
<?xml version="1.0" encoding="UTF-8"?>
<oimplugins xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<plugins pluginpoint="oracle.iam.platform.kernel.spi.ValidationHandler">
<plugin pluginclass="test.iam.eventhandlers.CustomValidationEventHandler" version="1.0" name="CustomValidationEventHandler" />
</plugins>
</oimplugins>
Just givng sys out in the below code to check whther it is getting triggerred during user create.
package test.iam.eventhandlers;
import java.util.HashMap;
import oracle.iam.platform.Platform;
import oracle.iam.platform.context.ContextAware;
import oracle.iam.platform.kernel.ValidationException;
import oracle.iam.platform.kernel.ValidationFailedException;
import oracle.iam.platform.kernel.spi.ValidationHandler;
import oracle.iam.platform.kernel.vo.BulkEventResult;
import oracle.iam.platform.kernel.vo.BulkOrchestration;
import oracle.iam.platform.kernel.vo.Orchestration;
public class CustomValidationEventHandler implements ValidationHandler {
@Override
public void initialize(HashMap<String, String> arg0) {
// TODO initialization
System.out.println("init validate event handler");
@Override
public void validate(long processId, long eventId, Orchestration orchestration)
throws ValidationException, ValidationFailedException {
System.out.println("Beginning of validation");
System.out.println("End of validation");
@Override
public void validate(long processId, long eventId, BulkOrchestration arg2)
throws ValidationException, ValidationFailedException {
// TODO - N/A
System.out.println("Bulk Orchestration not yet implemented");
Now when i create a user it is not allowing and i am getting system error in the front end and in the logs i could see something below
<May 28, 2012 3:03:29 PM CEST> <Error> <oracle.iam.identity.usermgmt.impl> <IAM-3050029> <The user cannot be created due to validation errors.

I have implemented preprocess and postprocess event handler before with similar kind of plugin registration, metadata import and everything worked fine. Not sure what is the problem here with validation event handler.
Thanks
DKInstead of registering the plug-in can u try placing it in the plugins folder under Oracle_IDM1/server folder.
at times restart is required. esp when the server is running in production mode.

Dropdown box - which event handler to use ?
I am having trouble with setting the readonly property (via Javascript) of the adjacent textbox to my dropdown box when the index value is a certain number.
I tried using MouseUp, MouseDown, and even OnBlur....but the readonly does not seem to be getting set to true or false consistently.
Could this be a timing issue ? The textbox that I am trying to control is the next tab-order control in the list of controls for this page.
This same logic is working fine in the MouseUp event handler for check boxes. So I am just wondering if this is a bug or must my implementation change to accomodate dropdown boxes ? For instance, should I move the logic to the Enter event handler of the textbox instead ? Can a control's own eventhandler set itself to readonly when it is the active form field ?After tons and tons of testing time, I've come to the conclusion that dropdowns are totally buggy in 11.0.07 release of Acrobat Pro.
Even if you set the "commit values immediately", you get the PRIOR selected item's value as the event value, not the CURRENT one.
This occurs in a Validate event handler script. I have not been able to use any other event handlers for a dropdown except the OnBlur....and then, for my purposes, IT'S TOO LATE !!!
This is totally worthless as I need to setFocus() and set fields to readonly based on the immediate dropdown offset or face value. -
Swing: when trying to get the values from a JTable inside an event handler
Hi,
I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
I put two buttons (plus labels) and a JTextField . The buttons have the following role:
One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
I would thank you very much for the help.

Hello all,
I have a problem with event handling. I have two buttons in my GUI application with the same name.They are instance variables of two different objects of the same class and are put together in the one GUI.And their actionlisteners are registered with the same GUI. How can I differentiate between these two buttons?
To be more eloborate here is a basic definition of my classes
class SystemPanel{
SystemPanel(FTP ftp){ app = ftp};
FTP app;
private JButton b = new JButton("ChgDir");
b.addActionListener(app);
class FTP extends JFrame implements ActionListener{
SystemPanel rem = new SystemPanel(this);
SystemPanel loc = new SystemPanel(this);
FTP(){
add(rem);
add(loc);
pack();
show();
void actionPerformed(ActionEvent evt){
/*HOW WILL I BE ABLE TO KNOW WHICH BUTTON WAS PRESSED AS THEY
BOTH HAVE SAME ID AND getSouce() ?
In this case..it if was from rem or loc ?
} It would be really helpful if anyone could help me in this regard..
Thanks
Hari VigenshHi levi,
Thankx..
I solved the problem ..using same concept but in a different way..
One thing i wanted to make clear is that the two buttons are in the SAME CLASS and i am forming 2 different objects of the SAME class and then putting them in a GUI.THERE IS NO b and C. there is just two instances of b which belong to the SAME CLASS..
So the code
private JButton b = new JButton("ChgDir");
b.setActionCommand ("1");
wont work as both the instances would have the label "ChgDir" and have setActionCommand set to 1!!!!
Actually I have an array of buttons..So I solved the prob by writting a function caled setActionCmdRemote that would just set the action commands of one object of the class differently ..here is the code
public void setActionCommandsRemote()
for(int i = 0 ; i <cmdButtons.length ; i++)
cmdButtons.setActionCommand((cmdButtons[i].getText())+"Rem");
This just adds "rem" to the existing Actioncommand and i check it as folows in my actionperformed method
if(button.getActionCommand().equals("DeleteRem") )
deleteFileRemote();
else if(button.getActionCommand().equals("Delete") )
deleteFileLocal();Anyway thanx a milion for your help..this was my first posting and I was glad to get a prompt reply!!! -
Javascript embedded in button pl/sql event handler not being executed
Javascript calls not working from pl/sql button event handler. What am I missing? Are specific settings needed to execute javascript from pl/sql proceedures?
Example: Want to toggle target='_blank' off and on in a button pl/sql event handler to open url call in new window & then reset when processing submit is done & the app returns to the form.
portal form button's pl/sql submit handler:
begin
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
end ;
Putting the following in the button's javascript on_click event handler works great:
this.form.target='_blank'
to force opening new window with a call in the button's submit pl/sql code via:
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
but then the target='_blank' is left on when the submit is done & we return to the form.
putting the above javascript as a function (called fcn_newpage) elsewhere (e.g., after form opens) & calling in the submit pl/sql with
htp.p('fcn_newpage') ;
also doesn't work.
Metalink thought this was an application issue instead of a bug, so thought I'd see if anyone knows what's going wrong here. (Portal 9.0.4.1)thanks for your discussion of my post.
Please clarify:
"htp.p('fcn_newwindow') sends a string":
What would you suggest the proper syntax for a function fcn_newwindow() call from a pl/sql javascript block that differs from
htp.p('<script language="Javascript">') ;
htp.p('fcn_newwindow');
htp.p('</script>');
or more simply
htp.p('fcn_newwindow') ;
More generally, what I'm trying to figure out is under what conditions javascript is executed, if ever, in the pl/sql of a button (either the submit or custom event handler, depending on the button).
I've seen lots of posts asking how to do a simple htp.p('alert("THIS IS TROUBLE")') ; in a pl/sql event handler for a button on a form, but no description of how this can be done successfully.
In addition to alerts, in my case, I'd like to call a javascript fcn from a pl/sql event handle that would pass a URL (e.g., http://www.oracle.com) where the javascript fcn executed
window.open(URL). The API call to set_target(URL) in pl/sql has no ability to open in a new window, so calling that is inadequate to my needs and I must resort to javascript.
Its clear in the PL/SQL of a button, you can effect form components since p_session..set_target & p_session.get_target set or get the contents of form components.
So to see if javascript ever works, I tried to focus on something simple that only had to set what amounts to an enviromental variable when we returned to the form after a post. I chose to try to change the html value of TARGET from javascript in the PL/SQL button because it doesn't need to be implemented until we finish the post and return to the form.
So I focused on a hack, setting this.form.TARGET='_blank' in the on_click event handler that forced every subsequent URL call or refresh of the form to be a new window. I then wanted to turn off opening new windows once I'd opened the URL call in a new window by setting TARGET='' in the portal form. I can achieve what I want by coding this.form.TARGET='' in the javascript (on_focus, on_change, or on_mousedown, ...) of every form component that might refresh the form. However, that is a ridiculous hack when a simple htp.p('<script>') ; htp.p('this.form.target=""') ; htp.p('</script>') ; at the end of the button's pl/sql event handle should do the same thing reliably if javascript ever works in the pl/sql event handler.
If we didn't have access to form components through p_session calls, I'd assume it was a scope issue (what is available from the pl/sql event handler). But unless my syntax is just off, when, if ever, can javascript be used in a portal form's pl/sql event handler for a button?
if I code a javascript funtion in the forms' pl/sql before displaying form:
htp.p('<script language="JavaScript">') ;
htp.p('function fcn_new_window(URL)') ;
htp.p('window.open(URL)' ) ;
htp.p('</script>') ;
the function can be called from a button's on_click javascript event handler:
fcn_new_window('http://www.oracle.com')
but from the same button's pl/sql submit event handler this call doesn't work: htp.p('fcn_new_window("http://www.oracle.com")')
So my questions remain: Is there other syntax I need, or does javascript ever work properly from the pl/sql of a form button's event handler? If it doesn't work, isn't this a bug that should be fixed by Oracle?
I can probably figure out hacks to make things work the way I need, but executing javascript from pl/sql event handlers seems to be the expected way to affect portal html pages (forms, reports, ...) and it seems not to work as expected. I don't feel I should have to implement hacks for something as simple as calling a javascript function from pl/sql when almost every example I've found in metalink or the forums or Oracle Press's "portal bible" suggests using javascript from pl/sql via the utility htp.p() to effect web page components in portal.
My TAR on the subject, while still open, returned the result basically: "We can reproduce your situation. Everything looks okay to us, but we can't explain how to use javascript where you want or point you to any documentation that would solve your problem or expain why it should not work the way you want it to. We don't feel its a technical issue. Why don't you post the problem on the portal applications forum."
I'm hoping I'm just missing something fundamental and everything will work if I implement it a little differently. So if anyone sees my error, please let me know.
by the way, not sure this is germain, but in reference to your comment:
"redirections in pl/sql procedures give a peculiar result. in a pl/sql procedure, usually, portals give the last redirection statement and ignore anything else coming after it."
if I try to raise an alert:
htp.p('alert("you screwed up")');
return;
in a pl/sql event handler, it still doesn't raise the alert, even though its the last thing implemented in the event handler. But if I set the value of a text box using p_session..set_value_as_string() at the same spot, it correctly sets the text box value when I return to the form. -
How to run a dialog's method from a button's event handler?
I've created my first dialog from the samples, but I am having trouble figuring out how to run a method in my dialog from an button's event handler. Can anyone please point me in the right direction?
function CreateDialog()
this.windowRef = null;
CreateDialog.prototype.run = function()
//...declare a bunch of vars
// Create a window of type palette.
var win = new Window("dialog", "Element Spray Generator",[iTop,iLeft,iTop + iWidth,iLeft + iHeight] ); // bounds = [left, top, right, bottom]
this.windowRef = win;
// Add a frame for the contents.
win.btnPanel = win.add("panel", [iPadding,iPadding,iWidth-iPadding,iHeight-iPadding], "");
.... add a bunch of other stuff ...
win.btnAdd = win.btnPanel.add("button", [win.btnRemove.bounds.left - iPadding - iButtonWidth,win.lstImages.bounds.bottom + iSmPadding,win.btnRemove.bounds.left - iPadding,win.lstImages.bounds.bottom + iSmPadding +iTextHeight], "Add");
win.btnAdd.onClick = function() {
//todo implement this
var f = File.openDialog("Open File") ;
win.lstImages.add("item", f.displayName );
this.EnableControls(); //<--- problem is on this line here!!
this.EnableControls(); //<--- this works
// Display the window
win.show();
return true;
CreateDialog.prototype.EnableControls = function (){
var result = true;
result = result && (this.windowRef.ddlPaths.selection != "");
result = result && (this.windowRef.lstImages.items.length > 0);
this.windowRef.btnOK.enabled = result;This may not be the reason, but when using the way I create dialogs 'this' inside of an onClick points to the control.
win.btnAdd.onClick = function() {
//todo implement this
var f = File.openDialog("Open File") ;
win.lstImages.add("item", f.displayName );
this.EnableControls(); //<--- I would expect it to call another function of btnAdd
// this.parent.EnableControls() might be what you want if the control is not in some other container -

BSP extension "download" - event handling problem
Folks,
First of all, I apologize if the answer is already out there, but I spent quite some time to find the solution for my problem but finally gave up:
I implemented the Download extension from Brian's and Tom's book. Since I am using an MVC based app, I put the event handling in the DO_HANDLE_EVENT of a controller instead of the OnInputProcessing event of a page. Here's how my app is designed:
I have a main controller that has an execute button to trigger a data selection based on some selection criteria. The result of this selection is displayed by means of a subcontroller with tableviews that are wrapped into my zdownload extension. Everything works fine: I make my selections, execute the app through the button of the main controller and get my result shown in the tableviews. I push the download icon, select my file format (XLS, HTML etc), get the dialog to choose whether to download or to display the file, perfect!
But now after I processed the download successfully - if I click the execute button in the main controller again, I still get the download dialog. It looks like the created event for the download does not get cleared. As I mentioned, I searched through SDN, but all I found were referrals to the call of DISPATCH_INPUT( ) in DO_REQUEST of the main controller, but unfortunately this one is already implemented.
Any ideas?
Thanks,
GuentherThere is an attribute of the download extension called display_url. You pass a value to the extension telling it what cached URL contains the binary content for your download. if this display_url attribute has a value assigned to it, then the element will render an iFrame to call the URl. However if the display_url attribute is empty, it won't render the iFrame. I suspect that you have a stateful application and after your download event you aren't clearing whatever field that you pass into the display_url attribute.

The following sample report shows how to handle event in principle (see the § marks)..
The following sample report show customer data ("Header"; KNB1) in the first ALV list and sales areas ("Detail"; KNVV) for the selected customer (event double-click) in the second ALV list.

Event Handling in labview with arrays as event data
Hey folks,
I have a Labview Application which uses a dll to read Ethernet data. The setup is such that, when the dll has fresh data it sends out an event to the Labview Application so that the fresh data can be displayed.
However i have only managed to get this event based mechanism to send out a single structure at a time. Hence if there are 10 fresh data values, i need to send out 10 events (each event structure contains the parameter name, parameter value, unit and time stamp). It would be more efficient to send out an array of structures in a sigle shot.
I have tried this but Labview keeps crashing saying that an error was encountered and Labview needs to close along with an access violation message. I did a lot of online searching and found some LV code for event handling but not come accross any implementation which uses arrays as evend data. Is this supoorted? And if so is there any example vi that can be shared so that i get some knowledge about this.
Many Thanks in adavance,
Abel.I also gave a try by using a variant as the event data type instead of the cluster which contains the array of floats. I converted the cluster into a variant and used that to create the user event reference. Followed the same logic while decoding the dats.
But still the crash.... Here is the windbg output...
