How to catch the ApplicationStart event??

how to catch the application start event??
i want to do some actions (Java code) that will be run once when the application started
this like ApplicationStart event in ASP.NET
how ???

Google for javax.servlet.ServletContextListener. You need to write a class that implements this interface and register it in web.xml.
Please ask questions like this in the JDeveloper or OC4J forum since they are not related to JHeadstart.

How to catch the mouse event from the JTable cell of the DefaultCellEditor

Hi, my problem is:
I have a JTable with the cells of DefaultCellEditor(JComboBox) and added the mouse listener to JTable. I can catch the mouse event from any editor cell when this cell didn't be focused. However, when I click the editor to select one JComboBox element, all the mouse events were intercepted by the editor.
So, how can I catch the mouse event in this case? In other word, even if I do the operation over the editor, I also need to catch the cursor position.
Any idea will be highly appreciated!
Thanks in advance!

Hi, bbritta,
Thanks very much for your help. Really, your code could run well, but my case is to catch the JComboBox event. So, when I change the JTextField as JComboBox, it still fail to catch the event. The following is my code. Could you give me any other suggestion?
Also, any one has a good idea for my problem? I look forward to the right solution to this problem.
Thanks.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test3
extends JFrame {
// JTextField jtf = new JTextField();
Object[] as = {"aa","bb","cc","dd"};
JComboBox box = new JComboBox(as);
public Test3() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container content = getContentPane();
String[] head = {
"One", "Two", "Three"};
String[][] data = {
"R1-C1", "R1-C2", "R1-C3"}
"R2-C1", "R2-C2", "R2-C3"}
JTable jt = new JTable(data, head);
box.addMouseListener(new MouseAdapter() {
// jtf.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e)
System.out.println("-------------------JComboBox mouseclick....");
jt.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e)
System.out.println("-------------------JTable mouseclick....");
// jt.setDefaultEditor(Object.class, new DefaultCellEditor(jtf));
jt.setDefaultEditor(Object.class, new DefaultCellEditor(box));
content.add(new JScrollPane(jt), BorderLayout.CENTER);

Personas 2.0: How to catch the selection event of a dropdown list?

Hi Personas 2.0 experts,
The use case:
I want to use a text field to show the "key" of an item that can be selected in a dropdown list.
The issue:
After clicking the list and selecting an item, the text field is not automatically updated with the newly selected item content.
Anyone has an idea to how make such an auto update (pls note I don't want to use an extra button to do the update, just by clicking the list only)?
Thx.
Dong

To display the key (the actual value) that's selected in a dropdown, there is a property called ShowKeys which you could set.
However if you'd want to show the selected value in another field upon picking an option, this would require an event associated in Personas 2.0 with the selection of a dropdown value. This is currently not available so I'm afraid what you are looking for is not possible.
Edit: It turns out I was wrong... there is an option (at least it's there in SP3) which allows linking a script button to the dropdown property OnValueChanged, so you can use this to do any script action you need when the user selects a value.
(thanks, Sushant )

How to catch the IllegalComponentStateException?

I have a JTable which has 3 columns, only the first column is editable. I got the following exception sometimes when I click the mouse on the column to bring up a popupMenu.

How to catch menu click events from B1AddOn Wizard

Dear Friends,
I'm adding some custom menus to the SAP BO main menù using B1 Addon Wizard generated code, but then I don't know how to catch the events generated by the menus.
Thank you for attention
Massimo

Thank you Eddy,
I had a look at the help, but there it is not explainsed that events can be attached only to string menus!!
It was attempting to do something wrong.
A further question: is it possible to add new menus and related events to an existing project (I tried with new item and then B1 Addon Component, but it doesn't let me add new menus)?
Thanks again

How could control the scroll events in ALV OO?

Hello experts!
I'm programing a report, inside there is a field that need time of processing. I'm using ALV OO.
I have thought that it could only calculate the field for the lines that visualize.
How could control the scroll events to calculate the field of the visualized lines?
I'm using CL_SALV_TABLE class and cl_salv_events_table to control the events, but there aren't any event to control the scroll.
best regards!

Hi Sriram,
I did view the information that you was attaching, but this don't resolve my problem. With methods get_scroll_info_via_id and set_scroll_info_via_id, we can get and put information of selection and view rows in the screen but we don't control when the user click in the scroll for advance or to back down a page.
I would like to refresh the data in ALV when the user view news rows.
I want your genial ideas.
Best regards!

How to catch the value in sum(control break statement).

hi,
can any one tell me how to catch the value in sum in control break satament.
ex.
at end of brtwr.
sum.
endat.
I need to print the value in sum only.
I tried to declare a varaible of type i and assigned sum to this variable.
it is giving syntax error that sum is not identified.
How should i do this.
regards.

Hi Siva,
In control break statement when we use SUM. it added all the amount fields and stores its in the work area of that field.
look below code.
DATA : BEGIN OF itab OCCURS 0,
           name(10),
           num TYPE i,
       END OF itab.
DATA : num TYPE i .
itab-name = 'salman'.
itab-num = 100.
APPEND itab.
itab-name = 'salman'.
itab-num = 200.
APPEND itab.
itab-name = 'akshay'.
itab-num = 500.
APPEND itab.
LOOP AT itab.
AT END OF name.
    SUM.
    WRITE : / itab-num.
ENDAT.
ENDLOOP.
here the SUM value is stored in Workarea,
the output will be 300 & 500.

fault message type

Hi Spring,
If u give an exception step along with your Transformation Step, whenever some error occurs in your message mapping, this exception block wil be triggered.
You can configure your exception block to do all exception processing that you want. This exception handling is like any other java Exceptio n Handler. You can do anything that you want in your exception handler block on the basis of your requirements.
<i>If an exception is triggered at runtime, the system first searches for the relevant exception handler in surrounding blocks. If it does not find the correct exception handler, it continues the search in the next block in the block hierarchy.
When the system finds the correct system handler, it stops all active steps in the block in which the exception handler is defined and then continues processing in the exception handler branch. Once the exception handler has finished processing, the process is continued after the block.
If the system fails to find an exception handler, it terminates the integration process with an error.</i>

Bhavesh

How to receive the custom event in the listening portlet (No backing file)

I have couple of portlets (JPF based). Portlet A is firing an event
     public Forward processAction()
          PortletBackingContext context =PortletBackingContext.getPortletBackingContext(this.getRequest());
          String message = "XXXXX";
          context.fireCustomEvent("customevent", message);
          Forward forward = new Forward("success");
          return forward;
I have configured the Portlet B's eventhandler to listen for the 'customEvent' and invoke the pageFlowAction 'listenForEvent'
     @Jpf.Action(forwards = { @Jpf.Forward(name = "success", path = "test2.jsp") })
     public Forward listenForEvent() {
          Forward forward = new Forward("success");
          return forward;
Portlet B's method listenForEvent is indeed getting invoked, but is there a way I can retrieve the 'Event' object (as fired by Portlet A) inside the listenForEvent. I could have done this via the Backing file, but for some reasons i cann't use the backing file. Is there a way i can get the CustomEvent and the associated payload in my listening JPF portlet, without a backing file?
The WLP version is 10.3

Hello,
I originally said:
All you should need to do is to modify the method signature for your event-receiving method. The method signature should be:
public void listenforEvent(HttpServletRequest request, HttpServletResponse response, Event event)
where Event is a com.bea.netuix.events.Event object. You can then cast this to a CustomEvent object.
But I mis-read your earlier post about catching the custom event and invoking a pageflow action. When you do that, you will lose the custom event's payload (your message), and there is no way to retrieve it from your pageflow action.
The only way you can actually retrieve the event's payload is using a backing file for the portlet, with a method having the signature I mentioned above. You can then set a request attribute with the event's payload and still have it invoke the pageflow action, at which time you could retrieve the request attribute value-- assuming you don't need to run this portlet over WSRP. Over WSRP, the event-handling and pageflow action-invoking lifecycles will happen with independent request objects, so you would need to store the event payload in session to work over WSRP.

How to catch the user defined exception in application service

Hi All,
How to catch the user defined exception in application service when it is throwed by the external service..
Regards,
Thirumurugan.

Hi,
    Thanks for your reply,
        Actually I am calling validate Login method of External service from the application service. When the login fails, my external service will throw user defined Exception.I want to catch the user defined Exception.
    But in the application service , validate Login method can catch only Invocation Exception and Engine Exception.
   These two exception are present in the Application service remote interface.
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException;
User defined exception is not present there. When i include the webservice as external service in CAF, it suppossed to generate the java file for the custom exception of validate Login method and this generated file should be included in the application service remote interface..
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException,
(generated file name of user defined Excpetion.
Then only validate login method of application service can catch the user defined Exception which is thrown by the external service.

Thirumurugan.p

How to disable the mouseWheel event in Flex2?

How to disable the mouseWheel event? Basically I want my
flex2 app not to respond to any mouse wheel events. Thanks.

I downloaded one of the PDF form (IMM5490) from cic.gc.ca and saved it on my computer after filling it up. Later on the following message popped up when I tried to open the form again later to in order to make some changes.
"This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document"
Your help in this regard will be greatly appreciated, since, I have already filled the form with a lot of information and I will not be able to edit the form with additional information unless I disable the extended features ( I guess).
