Event handling in custom Non-GUI components

I have a class which needs to fire events to outside. These events maybe captured by several objects in outside world. How can I achieve this? In so many places I read, they always refer to AWT and Swing whereas my objects don't have any dependency to GUI.
I simply need to fire an event from an object, and capture that event from other objects by registering event handlers.
I have experience in .Net programming with Events and Delegates (function pointers), but cannot find something like that in Java. All it offers is various kinds of GUI related Listeners where I can't find a proper help resource using them in Non-GUI components.

Create an event class that encapsulates the event as you want, create a listener interface that has a method like handleMyEvent(MyEvent me) and then add addMyEventListener, removeMyEventListener methods to your original class. Add a List<MyEvent> to your original class and add the listeners to it and then when events happen
MyEvent someEvent = new MyEvent();
for(MyEventListener mel : eventlisteners)
mel.handleMyEvent(someEvent);

Having an issue with event handling - sql database & java gui

HI all, have posted this on another forum but I think this is the correct one to post on. I am trying to construct this hybrid of java and mysql. the data comes from a mysql database and I want it to display in the gui. this I have achieved thus far. However I have buttons that sort by surname, first name, ID tag etc....I need event handlers for these buttons but am quite unsure as to how to do it. any help would be much appreciated. Thanks in advance.

OK, so you've got this code here:
private class ButtonListener implements ActionListener {
public void actionPerformed (ActionEvent e) {
    if (e.getSource () == exit) {
      System.exit(0); // exits the GUI
    if (e.getSource () == snam) {
    if (e.getSource () == id) {
}Perfect fine way to do this; although I think creating anonymous would be a bit cleaner:
snam.addActionListener(new actionListener() {
public void actionPerformed(ActionEvent ae) {
});But I think that the real question you have is "what do I put for logic when the JButtons are hit?", right?
I would answer that you want to dynamically build your SQL statement changing your ordering based on the button.
So you'd have a method that builds the SQL based on what you pass in - so it takes one argument perhaps?
private static final int NAME = 1;
                         ID = 2;
/* ... some code ... */
snam.addActionListener(new actionListener() {
public void actionPerformed(ActionEvent ae) {
    buildSQL(NAME);
/* ... some code ... */
private void buildSQL(int type) {
if ( type == NAME ) {
/* ... build SQL by name ... */
else if ( type == ID ) {
/* ... build SQL by id ... */
}That kind of thing.
Or you might choose to have several build methods with no parameter type; each building the SQL differently, and calling whichever one you need. I did not read your entire pgm, so I don't know how you'd want to organize it. You need to ask more specific questions at that point.

Making custom non-standard components aware of custom look and feels.

Hello all.
Maybe the subject of this post could also be the opposite: "Making custom look and feels aware of non-standard custom components". I'm not sure.
If I code a new custom component (extending JComponent, or extending the UI delegate of a standard component) and pretend it to be laf aware then I must create the corresponding UI delegate for each laf, like it happens to be with standard swing components. But I'm not sure it is feasible to create the UI delegates for all unknown existing custom lafs.
On the other side, if I create a custom laf then I will also create a custom UI delegate for each standard component, but I can not create UI delegate for all unknown existing custom components.
The point here is that standard components and standard lafs are universally known, while custom components (or custom ui delegates) and custom lafs are not.
So the question is: How does a swing developer deal with the case of a new custom component that will be used in an unknown custom laf?
For instance:
1. Custom text UI delegate for dealing with styled documents in JTextField. See {thread:id=2284487}.
2. JTabbedPane with custom UI delegate that paints no tab if the component only contains one tab.
In both cases I need a UI delegate for each known laf, but what happens if the application is using a laf that certainly will not be aware of this custom functionally?
Thank you!

Where can I find an event handling for non gui purposes good tutorial

Hello to all, I am searching the net for a good tutorial about java Event and Event handling that is not GUI related.
All I find on the net are tutorial and examples that are related to GUI components the has pre defined events and handlers.
please help me find good material to learn from.
Appreciate it a lot.
Dan

I'd say goto the Java tutorial (www.thejavatutorial.com) and check up from there. Just because most event handleing is done in GUI's (swing comes to mind) doesn't imply its limited to that. For an example, check out the JavaBeans trail. Beans have ways to communicate with each other when (for example) a change in the bean occurs. Thats done through an event yet isn't related to GUI's in any way.

EmailRecieved Event handler for incoming email in Sharepoint 2013

Hi,
I am developing custom event handler to enable incoming email for custom document library. i have couple of questions.
1. Once i attached the event handler, i could see incoming email settings for the custom document library, but it displays only 2 options as below :
              1. Allow this document library to recieve email
                             Yes       No
                2. E-mail address
All other properties are not displaying. Is this normal behaviour on custom event handler for custom document library or any issue anywhere?
2. So i have given other properties using powershell as below:
$list = $web.lists["invoice Documents"]
$list.EmailAlias ="TestDocument"
$list.EnableAssignToEmail = $true
$list.rootFolder.Properties["vti_emailusesecurity"] = 1
$list.rootFolder.Properties["vti_emailsaveattachments"] = 1
$list.rootFolder.Properties["vti_emailattachmentfolders"] = "root"
$list.rootFolder.Properties["vti_emailoverwrite"] = 0
$list.rootFolder.Properties["vti_emailsavemeetings"] = 0
$list.rootFolder.Properties["vti_emailsaveoriginal"] = 0
$List.RootFolder.Update();
$list.Update();
here i have given vti_emailusesecurity as 1, so it should allow incoming email for the user who has permission for the list.
But any user from the domain is sending mail to this list, the Emailrecieved event handler is triggered. I am expecting that this event handler should not be triggered and expecting access denied error in the ULS Log. But that is not happening, and emailrecived
is triggered and email is delivering to this address successfully.
Can you please anyone help if experience on this?
Thanks

'Call' in PL/SQL button event handler

I have created a form with only one 'Custom' button on it.
In the PL/SQL button event handler, in 'Custom' event item, I
inserted some PL/SQL code and, at the end, a call like the
following:
my_url:= 'PORTAL30.wwv_component_control.run_as_portlet?'
|| 'p_module_id=' || '2836550185';
call(my_url,return_url);
I have a compilation error:
"PLS-00201: identifier 'CALL' must be declared"
I also tried to put this code in 'On successful submission of a
form'. I have no compilation error but it doesn't work.
Anybody knows hw to solve this problem?
Thanks.

Hello Antonnella,
I have a good tip for you:
write the next scirp in the 'On successful submission of a
form'field in the form where you want to call the component:
declare
l_url varchar2(2000);
begin
l_url := 'the url of the component you want to call' ;
PORTAL30.wwa_app_module.set_target(l_url,'CALL');
end;
you can get the url from:
develop -> call interface:show -> Example of Call from URL .
Success,
Haseeb

How to handle events between two custom components?

Hi ,
i want to handle events between two custom components, example if an event is generated in one custom component ,and i want to handle it any where in the application.....can any one suggest me any tutorial or meterial in this concept...
thanks

Events don't really go sideways in ActionScript by default. They bubble upward. If you want to send an event sideways, you will probably have to coordinate with something higher up in the event hierarchy. You can send the event to a common ancestor, and then pass it down the hierarchy as a method argument.
Another option is to use a framework that supports Injection. There are a number around these days. The one I'm most familiar with is Mate, which allows you to handle events and inject data in MXML. Mate is meant to be used as an MVC framework, and you may want to look into it if your application is complex, but you can also use it to coordinate global event handling if you don't need that level of structure.

Can we apply an event handler only for a custom request in oim 11G?

Hi,
We would like to create a custom request for user creation, modification etc.
I saw that event handlers allow to add business rules by running java code during differents steps of processes.
I would like to know if we can trigger an event handler on a specific request and not on all user CREATION, UPDATE etc.
For example, we would like to have differents creation requests and a differents event handler on each request.
And can we add "logical" input on request form and read them in event handler?
For example, 3 inputs: day, month and year on the form which fill one user attribute "end contract date".
Regards,
Pierre

thank you Akshat,
I saw part 19 in the developper's guide. If I understand, I can change the default CreateUserRequestData to define ALL form components that will be used in my differents user creation request templates.
I can use prepopulation adapter to pre populate field with java code.
I can use the plug-in point oracle.iam.request.plugins.StatusChangeEvent to run custom java code.
But they don't mention where you can run java code for a specific creation template named "MyUserCreationTemplate1" and other java code for an other specific creation tempalate" MyUserCreationTemplate2".
That makes me think we must retrieve the template name in java code and execute the appropriate business logic.
if request name==MyUserCreationTemplate1

How to set up a label control from custom event handler?

Hi,
Below I try to describe my problem:
I have a single instance of MyClass (I use Cairngorm framework), with ArrayCollection as a variable, in which I would like to keep a couple addresses from database.
Additionaly I created a custom components with a list of people retrieved from database, with eventhandler for a doubleclick event. After I doubleclick on some person, I create a custom event and dispatch it. In command class connected with this event I connect to the database and get full data about this person and a set of her addresses. This set of addresses I placed into ArrayCollection in my model variable. And now I have a problem, because one of this address (the birth place) I would like to display below the list with persons, in a Panel with a couple of label control, but .... I can't to bind label control to my model.addresses[???] because I don't know if this doubleclicked person has this birth address at all?
I wonder if it is possible to set up label control in my custom components in time when I'm receiving the data from database in my custom event handler???
One of the way to achieve this is to define a string var in my model and placed this special address in it, and then the label control to this variable, for instance {model.birthplace}, but this is only needed for a moment, I don't want to keep this address in extra variable in model, because I have already it in my ArrayCollection in model, so it would be a duplicate.
I hope that you could understand me and my english :-)
Best regards

Looks like I migh not be a novice swing programmer for long then.

Non-graphical event handling

Hi
I want to make an Object listen to an Event created by another Object, I mean :
Object1 --- Event ---> Object2 ---method---> Finish
so that Object1 is an instance of a class A, Object2 an instance of a class B, and when A creates an Event "CalculDone", B receives it and starts the AfterCalculIsDone method. Unfortunately I don't know how I can handle events that are not created by components but that are created by not-in-a-GUI running code. Could you help me ?

Ok, the thing is, when you say "event" in java, we're specifically referring to GUI stuff. like without events, how would we find out when a button was pressed, etc. it doesn't make sense in java to talk about events outside of that area, as far as I know.
what im thinking is, you need an algorithm that needs to call certain methods upon certain things happening. honeslty, maybe i'm being dense but I still can't understand why you can't say this:
if(test_your_constraint)
call_all_the_other_methods_that_should_know_about_this_to_update_their_class_info
but I'm thinking that if that's not what you're talking about maybe you're talking about a branching algorithm or a backtracking algorithm. ie. when you find out certain constraints, you're equations need to take a different direction or when you find out they're going in the wrong direction, backtrack to start a new way.
btw, what's your programming background, maybe that'll help me figure out what you need.

Non-GUI events in Java

I was wondering how I would have to go about writing an event handling mechanism on something that is not GUI-based (non-AWT/SWING)!
Supposing one wanted to write an event listener that would tell them when a data structure is updated - e.g: in a typical producer-consumer model, where the consumer is to be notified of fresh entries whenever a producer writes integers to some data structure...
Does Java have classes/methods to handle such non-GUI-based 'events'? Is this a commonly found scenario in Java programming?
Thank you!

What you're looking for is the Observer-interface. Check out http://java.sun.com/j2se/1.4/docs/api/java/util/Observer.html
and

Custom event handler

Just curious. I made a custom event handler that is
dispatched from within a class when an XML document is loaded. The
listener is attached to the instance of that class in the FLA. The
attached code to this thread is what is for the class instance.
Does that have to be out there? Is there a cleaner way to do it so
that the code would be away in a class? Just wondering....
Thanks!

Well I need my instance to know when the data is loaded into
the object, but I wish there was a more transparent way to do it. I
guess I could somehow put that stuff into the initiation of the
class....

Custom Pre Process Event Handler in OIM 11g for middle initials

Hi,
I am trying to congiure a Custom Pre Process Event Handler for generating middle name in OIM 11g and I am following the steps as given in metalink ID: *1262803.1*
Even after successfully performing all the steps I am not able to get the middle initials in Admin Console when I create a new user.
1) Directory structure for the application that I have created through JDeveloper.
CustomApplication/
|-- CustomApplication.jws
`-- CustomProject
|-- CustomProject.jpr
|-- classes
| `-- com
| `-- example
| `-- custompph
| `-- CustomPreProcessEventHandler.class
`-- src
`-- com
`-- example
`-- custompph
`-- CustomPreProcessEventHandler.java
2) Directory structure for Plugins directory
My Plugin.xml :
<?xml version="1.0" encoding="UTF-8" ?>
<oimplugins>
<plugins pluginpoint="oracle.iam.platform.kernel.spi.EventHandler">
<plugin pluginclass="com.example.custompph.CustomPreProcessEventHandler"

</plugins>
</oimplugins>
plugin/
|-- lib
| `-- com
| `-- example
| `-- custompph
| `-- CustomPreProcessEventHandler.class
|-- middlename.zip
`-- plugin.xml
Copied the middlename.zip in the plugin folder in OIM_HOME and registered it successfully.
3) Created a EventHandlers file and imported it successfully using importmetadata.
My EventHandlers.xml:
<?xml version='1.0' encoding='utf-8'?>
<eventhandlers>

<action-handler
class="com.example.custompph.CustomPreProcessEventHandler"
entity-type="User"
operation="CREATE"
name="CustomPreProcessEventHandler"
stage="preprocess"
order="10"
sync="TRUE"/>
</eventhandlers>
I checked the logs as well but could not find something which can help me to proceed.
Also please advise is their any mapping that I need to do in *"Design Console"*
Please advise !!!!!
Thanks

My lib file contains the package as mentioned in the metalink.
Heirarchy in Plugin folder :
1) plugin.xml
2) Lib ( lib contains 3 folders : com/example/custompph; And inside custompph is my CustomPreProcessEventHandler.class file)
You mean to say i should not copy the entire package in lib but only the jar file of the CustomPreProceessEventHandler.class* file.
If i put only a .jar file in lib i get the following error.
"Error occured during the use of plugin registering utility. The plugin zip does not contain the definition of plugin class com.example.custompph.CustomPreProcessEventHandler"
Thanks

Event handling in zranges custom tag

Hi,
I am using the tutorials by Thomas Jung on the ranges. I am faces a very strange problem. I have created that extension. My application framework is like bsp_model application. I have one main controller and two sub controller. when ever I chose any option,
An event is generated and do_Handle_event of main controller is called but ideally the do_handle_event of right controller should be called .Any Explanation about this behavior.
regards
Ashish

Hi Dezso,
> <i>the event handler of the main controller is always called</i>
As far as I know the Do_Handle_Event is called only for the controller in which event has been triggered it may be any sub-controllor or main controllor.
You are right that we dispatch the event through calling method Dispatch_input( ) in the Do_Request( ) method of main controller. Dispatch_Input do the followings...
1. First it calls Do_Handle_Data of sub-controllor's in the same order as they are instansiated in the main controllor and then finally Do_Handle_Data of main controllor is called.
2. Now Do_Handle_Event is called only for the controllor where event is triggered.
3 Now Do_Finish_Input is called in same sequence as Do_Handle_Data .
Correct me if I am wrong somewhare till now.
Now let me explaine my problem in detail...
I am using custom tag zranges in a view which is registered to a sub-controllor, I want to trap the event triggered when any option is selected but I am unable to do that. Please suggest me some solution to this prblem.
Thanks and Regards,
Ashish
