Re: [SunONE-JATO] How to Access methods in the MainAppServletBase class from a view bean

OK, fair enough.
Look at the ServletConfig class.

You should be able to get this info when the

from a props file.
Does this info change from day to day? If not, why
not create a props
file on the machine that the app is running that has
this info?
Then in the servlet's init method, read this prop
file.
Does that work for you? Not sure how a user request
is needed to
determine this? If it is, please explain.
I have used this same technique for database
properties (servername,
instance name, uid, pwd, etc).
On the QA machine was the properties that pointed to
the QA database,
and on the Production machine, the property file
with the same name had
props that pointed to the Production database.

I'm not suggesting that this is request scoped,but

If so, then do this in the module servlet's
onNewSession event.
If this is per user, then storing it staticallyis
problematic because
all users will be using the same data which Idon't
think you want.
Let me know if my assumptions are correct.

Be careful about how you update this URL

The servlets in JATO are the only shared

you could potentially

I

Accessing object of the main class from the thread

Hi, I'm having problem accessing object of the main class from the thread. I have only one Thread and I'm calling log.append() from the Thread. Object log is defined and inicialized in the main class like this:
public Text log; // Text is SWT component
log = new Text(...);Here is a Thread code:
...while((line = br.readLine())!=null) {
     try {
          log.append(line + "\r\n");
     } catch (SWTException swte) {
          ErrorMsg("SWT error: "+swte.getMessage());
}Error is: org.eclipse.swt.SWTException: Invalid thread access
When I replace log.append(...) with System.out.println(..) it works just fine, so my question is do the log.append(..) the right way.

This is NOT a Java problem but a SWT specific issue.
It is listed on the SWT FAQ page http://www.eclipse.org/swt/faq.php#uithread
For more help with this you need to ask your question on a SWT specific forum, there is not a thing in these forums. This advice isn't just about SWT by the way but for all specific API exceptions/problems. You should take those questions to the forum or mailing list for that API. This forum is for general problems and exceptions arising from using the "core" Java libraries.

How to access objects in the Child Form from Parent form.

I have a requirement in which I have to first open a Child Form from a Parent Form. Then I want to access objects in the Child Form from Parent form. For example, I want to insert a record into a block present in Child Form by executing statements from a trigger present in Parent Form.
I cannot use object groups since I cannot write code into Child Form to first create object groups into Child Form.
I have tried to achieved it using the following (working of my testcase) :
1) Created two new Forms TESTFORM1.fmb (parent) and TESTFORM2.fmb (child).
2) Created a block named BLK1 manually in TESTFORM1.
3) Created two items in BLK1:
1.PJC1 which is a text item.
2.OPEN which is a push button.
4) Created a new block using data block wizard for a table EMPLOYEE_S1. Created items corresponding to all columns present in EMPLOYEE_S1 table.
5) In WHEN-NEW-FORM-INSTANCE trigger of TESTFORM1 set the first navigation block to BLK1. In BLK1 first navigable item is PJC1.
6) In WHEN-NEW-ITEM-INSTANCE of PJC1, code has been written to automatically execute the WHEN-BUTTON-PRESSED trigger for the "Open" button.
7) In WHEN-BUTTON-PRESSED trigger of OPEN item, TESTFORM2 is opened using the following statement :
open_form(‘TESTFORM2',no_activate,no_session,SHARE_LIBRARY_DATA);
Since its NO_ACTIVATE, the code flows without giving handle to TESTFORM2.
8) After invoking OPEN_FORM, a GO_FORM(‘TESTFORM2’) is now called to set the focus to TESTFORM2
PROBLEM AT HAND
===============
After Step 8, I notice that it passes the focus to TESTFORM2, and statements after go_form (in Parent Form trigger) doesnot executes.
I need go_form with no_activate, similar to open_form.
Edited by: harishgupt on Oct 12, 2008 11:32 PM

isn't it easier to find a solution without a second form? If you have a second window, then you can navigate and code whatever you want.
If you must use a second form, then you can handle this with WHEN-WINDOW-ACTIVATED and meta-data, which you have to store in global variables... ( I can give you hints if the one-form-solution is no option for you )

Accessing a private variable from a public method of the same class

can anyone please tell me how to access a private variable, declared in a private method from a public method of the same class?
here is the code, i'm trying to get the variable int[][][] grids.
public static int[][] generateS(boolean[][] constraints)
private static int[][][] sudokuGrids()
    int[][][] grids; // array of arrays!
    grids = new int[][][]
    {

Are you sure that you want to have everything static here? You're possibly throwing away all the object-oriented goodness that java has to offer.
Anyway, it seems to me that you can't get to that variable because it is buried within a method -- think scoping rules. I think that if you want to get at that variable your program design may be under the weather and may benefit from a significant refactoring in an OOP-manner.
If you need more specific help, then ask away, but give us more information please about what you are trying to accomplish here and how you want to do this. Good luck.

How to access MailItems within the Message View?

I'm working on an Outlook 2013 plugin that needs to access the emails currently displayed in the Message View.
I already searched around a lot but I could only find ways to list emails by folder (and also the current folder). E.g.
Outlook.MAPIFolder curFolder = this.Application.ActiveExplorer().CurrentFolder;
Outlook.Items mailItems = curFolder.Items;
MailItem item = mailItems.GetFirst();
This would work fine if the user didn't apply any search filters; but if a filter is applied via the instant search bar this code would produce the same list of MailItems as if the filter wasn't applied.
I thought of two ways of potentially solving this but couldn't find any resources online that worked for either. 1) Preferably, get direct read access to the MailItem list currently rendered within the Message View. 2) Alternatively, read the value in the instant
search text-box and apply that to the currently selected folder using the Items.Find()
command.
From what I've read I don't think either of these elements have supported direct access in the Outlook Object Model; but there must be some way to solve this problem. I've also tried using
this.Application.ActiveExplorer().Filter;
but this appears to output a DASL query in the format ("http://schemas.microsoft.com/mapi/id/{00062008-0000-0000-C000-000000000046}/85700003" = 0) so I'm unsure if this is could be reformatted or be used as a filter.
Any guidance or explanations would be greatly appreciated; thanks in advance.

Hello Davon,
The Filter property is useless in that case. I spent some time researching that and found the following way:
The
GetTable method of the TableView class returns a Table object
that represents all of the Microsoft Outlook items that are contained in a TableView object.
Here is what MSDN states:
The GetTable method of the TableView object
returns a table of items from one or more folders in the same store or spanning over multiple stores, in an aggregated view. For example, an aggregated view obtained by a search across all mail items by using Instant Search. This behavior differs from the GetTable method
of the Folder object,
which obtains a table object that contains items from the same folder.
private void DemoViewGetTable()
// Obtain the Inbox folder.
Outlook.Folder inbox =
Application.Session.GetDefaultFolder(
Outlook.OlDefaultFolders.olFolderInbox)
as Outlook.Folder;
// Set ActiveExplorer.CurrentFolder to Inbox.
// Inbox must be the current folder
// for TableView.GetTable to work correctly.
Application.ActiveExplorer().CurrentFolder = inbox;
// Ensure that the current view is a table view.
if (inbox.CurrentView.ViewType ==
Outlook.OlViewType.olTableView)
Outlook.TableView view =
inbox.CurrentView as Outlook.TableView;
// No arguments are needed for View.GetTable.
Outlook.Table table = view.GetTable();
Debug.WriteLine("View Count="
+ table.GetRowCount().ToString());
while (!table.EndOfTable)
// First row in Table.
Outlook.Row nextRow = table.GetNextRow();
Debug.WriteLine(nextRow["Subject"]
+ " Modified: "
+ nextRow["LastModificationTime"]);

I need to know how to access and use the Blue Tooth device that comes with the Thinkpad W520

Forgive me for being a techo illiterate. But I know that this thing supports Blue Tooth. And one "problem" with it is although it has a DVD and sound card, music and movies have very lousy audibility. Is there something I can do about that? I can barely hear anything on a movie unless I plug in head phones to the computer. But that leaves me stuck in my seat. I'd like to get cordless headsets. And I'm ready to purchase the Plantronics BackBeat 903+ Wireless Stereo Headphones - Mic, Rich Audio, Bass-boost, Voice Alerts, OpenMic, 3-way Earpiece. And have heard that it's compatable with a pc that has Bluetooth capabilities. but could someone get back to me with exactly how I access and use the Blue Tooth device?

I was searching for how to setup the 903+ and my W520 and came to this thread.
1. The OP was asking about audio and there are updated audio drivers / tweaks to get it louder / install different drivers.
but if you are going to go BT headset....
2. What I did for the 903+
Uninstalled the currently installed ThinkPad Bluetooth program. ( I forget the exact name, came stock and was out of date).
Required reboot.
Activated the Bluetooth with FN + F5 menu.
Downloaded the updated Bluetooth driver from lenovo (search lenovo driver matrix).
Ran the updated Bluetooth driver install.
Rebooted for good measure.
Double-clicked the Bluetooth Tray icon.
Clicked Add A Device.
Turned off my 903+ and continued to hold down the power to enable pairing mode.
Showed up in devices and added it.
Worked for audio. There are probably additional options for enabling the mic.
Hope that helps whoever might find this thread.

Realtime data for a flash game - how to access/handle/poll the back end.

Hi,
I'm about to start working on a game that will be played on multiple consoles simltaneously. The user input from each console will be fed into a server and would populate a database/external store. This needs to be a client/server architecture where the flash client (the game on the kiosk), works on real time data that it gets from the server. Keeping in mind the "real" time aspect of the gamelplay and that it would involve multiple users at a time, I'm not really sure of how to interface the database with AS. The back end will essentially be PHP/MYSQL driven and I was thinking of maybe using AMFPHP service calls. But would this be efficient for a real-time setup ? Also, the users of the game, can be playing it physically on a touch screen kiosk , on the web, on SMS all at the same time!!
There are aspects in the game design, where a character changes animation based on their input. For example: If a user is playing an auction game and if his bid is the lowest (at the time of bidding), his character might start jumping. I'm not sure how to access this real time information from the database so that I can use it in Flash succesfully for such a client/server based multiplayer game.
Please advice.
Thanks
smaira

you would use the urlloader class from flash to access your server-side php and your php will query your database.

How to access JNDI tree of Admin Server from Managed Server

Passing values between methods in the same class

Hi,
How to pass internal tables or values between methods in the same class.
How to check if the internal method in another method is initial or not.
How to see if the method has already been executed.
Thanks.

Just declare the internal table as an attribute in the class - that way every method in this class has access to it.
Since any method has access to all class attributes you can easily check if the internal table is initial or not.
I am not aware of any standard functionality if a method has already been executed or not, one way would be to declare a class attribute for each method and set it once the method has been executed. That way every method in that class would know which method has already been executed or not.
Hope that helps,
Michael

How can I find out the mail server from email address?

Hi:
How can I find out the mail server from email address?
for example: If I know the email address is [email protected],
how to find the pop3 and smtp mail server?
THANK YOU

You can't tell by the email address since you can pretty much put whatever you want in there (especially if the SMTP server is not filtering anything).
The header may be able to tell you something. There is a Received header value which looks like it has the routing information although I am not sure if this is a complete trace or just the last hop the message took.
