How to acheive this?? Pls help

Our project has almost completed the development.
My client has requested to migrate the database.
we are migrating from db2 to db2e.
DB2e allows only one database connection.(limitation of db2e)
ie i have to close the current connection object before
getting the new Connection object.
I cannot have a Connection pooling also.
I have many links on my home page where every link
needs the connection object to do some database operations.
As i can have only one database connection, when i click
on the links repeatedly or when i play around with the links,
i get exceptions saying that i cannot have more than one connection
and results in a blank page or error page.
Currently my application has to handle this situation,
ie even if the user clicks continuosly on all the links or plays
around with the links it has take the last request into account
and display accordingly
I have a databaseConnection class which returns me a Connection object
To achieve the above funtionality i tried making the Connection object as static, so whenever i call the function to get the Connection object i check whether the current connection object is open or is not null.
if it is open i close and make it null and return the new connection object.
This seems to be working to some extent but not stable.
Iam not sure how does the server process when many requests are made and only one connection object is available at any point of the time.
Iam not sure how to get it working and stable.
One more solution i can think of is to declare a global variable
which tells us whether a request has been made.depending on this
variable i can restrict the user by clicking on the links reapeatedly.
but this is very tedious and also i have a time constraint.
any advice
tks in advance

just curious,couldn't you keep one connection open and through that connection run queries of different types?

pls help on how to send contacts from mac to blacberry phone

Sadly Mac OS X 10.9 did indeed remove sync services. You can either wait for http://www.markspace.com/ to improve their software to support it on its own, contacting them asking they do so, or if your machine is older than Mavericks boot off of the original operating system it came with when you need to sync data from contacts and calendars, or get an iCloud compatible device for syncing.

Have you asked your mobile phone operator to turn on roaming for you? and if you have you will need to turn on DATA ROAMING on the iPhone by going to SETTINGS > GENERAL > MOBILE DATA and turn on DATA ROAMING. You should then be able to see the various Indian Networks listed in SETTINGS > CARRIER and be able to make/receive calls.
If you are in India and didn't ask for Roaming to be activated on your mobile account you're stuck until you return to the UK.
OR
If you have a 'locked' phone that is tied to the UK operator then you will need to find a phone shop that unlocks iPhones but beware this invalidates any Apple Warranty. If you are still in the UK then phone the mobile operator and ask then to unlock your iPhone which they usually do if its not in a contract with them or at the end of the contract period.
Hope that helps a little, Andrew

When I want to add items to the bookmarks toolbar, for example: -Zoom toolbar. The zoom Toolbar appears on the bookmarks toolbar, but it shows the favicons aswell the underlined text. I only want the favicons. How to do this, please help!!

I want to add items to the bookmarks toolbar. for example: the Zoom Toolbar addon. This works, but not only the favicons appear on the bookmarks toolbar, aswell as the underlined text. How to avoid this?
I only want the favicons from an addon to appear on the bookmarks toolbar, not with the underlined text. How to do this?
This problem doesn't happen with any other toolbar. And this problem didn't happen with an earlier version of firefox. Please Help!
Thanx, BassMann.

If you only want the favicons and not the names of the bookmarks on the bookmarks toolbar, you can do that with the [https://addons.mozilla.org/en-US/firefox/addon/4072/ Smart Bookmarks Bar] add-on.

IMac takes forever to fully boot -- how to fix? PLS HELP!

On my iMac, I often have to wait like 30 seconds to like 1.5 minutes between the time I press the power button and when I can start doing stuff. (I remember it used to be like 20 seconds always.) Usually I can't click on anything and the dock doesn't respond to mouse-overs while the toolbar on top takes its time to load up the spotlight, time, localization, and airport icons. (I don't use Airport btw, that's just for me to enable it if the Ethernet is unavailable.)
I think the problem started not too long after I had first gotten the iMac (maybe a couple or a few months?). This is something I've come to expect with Windows, but not with Mac.
At first I just tolerated the issue, but then I finally tried to solve the issue. I uninstalled VM software like Parallels and VMware Fusion, and I even uninstalled Office 2008 (and I think Adobe Design Premium CS3 also), with no luck. I tried going by suggestions from tech support: I ensured that there were no unnecessary startup items or services, that the desktop was clean, that disk permissions were fine, and that the problem wasn't specific to my login account. I even reset the PRAM. Nothing really solved the issue.
What can I do? If I re-install Tiger will that solve the issue? If I upgrade to Leopard will that solve the issue? If I upgrade to 2GB RAM will that solve the issue? And if I do install Leopard or re-install Tiger, will I still have all my software and files safe?

Check to see if you have any startup items you don't really need - these can cause a delay as to large numbers of fonts.
Other things which hamper performance include:
A very cluttered desktop. Store your work in progress and finished work in sub-folders inside the user > documents folder - as simple as this sounds it is a great resource saver
Backup regularly. Work that you do not touch more that once a year should be backed up to CD, DVD or an external hard disk. It is pointless and expensive to keep this sort of work on your working volume if you access it infrequently. If your startup disk is ±75% full this will have serious consequences on the performance of your Mac.
Make sure you have enough RAM. RAM is presently cheap so its worth considering.
Carry out a “repair permissions” - it is a good idea to do this once a month. You can find an article on how to do this in my tips archive (see link below).
Using “Cron” Scripts helps keep your Mac healthy by deleting cumbersome log files. Applications such as Onyx, Mac Janitor or MainMenu do this for you at the click of a button.
Do not, repeat not, use Internet Explorer. This ancient browser has not been updated for years and will cause you no end of grief. Use Safari, Firefox, Opera or one of the other browsers available for Mac.

How to acheive this output during the XML conversion ?.

I am converting the data into XML. I am using Oracle8i.

How to acheive this???? J2EE gurus

Hi,
I have servletA in one serverA and servletB in ServerB.When a request is made to servletA it should call the ServletB to get the response.
Basically they should be chained.
I understand that to forwarding a request to a servlet which is in a different context we have to use redirect instead of forward.if we user redirect the server issses a new request.
How can i acheive this???
Thanks in advance.

The Client is imp bcos it is the one which receives
the response.
I would like to one thing.
if PDA makes a request to ServletA which is on
ServerA and the ServletA makes an HttpURLConnection
and contacts ServletB which is on ServletB, how can i
inlcude the response sent by servletB into ServletA
response????
ServletB is writing everything into response object.
Thanks
You could use a method like this. Though you might have to modify ot as per your requirements
private void returnSuccessfullNotifyHttpResponse(HttpServletRequest request, HttpServletResponse response, String pushId)
                                         throws ServletException, IOException {
    String responseString =null;
    PrintWriter out=null;
    String replyTime = null;
    Calendar date = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
    String year,month,day,hour,minute,second;
    year=Integer.toString(date.get(Calendar.YEAR));
    month=Integer.toString(date.get(Calendar.MONTH) + 1 );
    if (month.length() == 1)
      month = "0" + month;
    day=Integer.toString(date.get(Calendar.DAY_OF_MONTH));
    if (day.length() == 1)
      day = "0" + day;
    hour=Integer.toString(date.get(Calendar.HOUR_OF_DAY));
    if (hour.length() == 1)
      hour = "0" + hour;
    minute=Integer.toString(date.get(Calendar.MINUTE));

      minute = "0" + minute;
    second=Integer.toString(date.get(Calendar.SECOND));
    if (second.length() == 1)
      second = "0" + second;
    replyTime = year+ "-" + month + "-" + day+ "T" + hour+ ":" + minute + ":" + second + "Z";

How to acheive this scnerio in PL/SQl using collections

Hi All,
In my apllication we are handling two types of procedures which runs based on the jobs.
Due to some problem few records where got missed in prouduction.
We have tried to run this jobs manaually one by one and it is taking time to execute..
I have got a suggetsion from my senior to do in a collection and run this packages at a time..
Here is my exact scenerio, can you please help me out to implemnet in collections..
Steps:
Populate the missing records namely ordered, event sequence, Start date, end date, region in to plsql table/collection. ( Hard-coded since this will run the code
for a date which will take less time and take less record).
looping the plsqltable/collection for missing records
Running the procedure p_Daily with startdate and end date parameter
-- if the above executed successfully we need to execute second procedure i.e p_Region procedure by checking records in f_daily_report exist/relevant table
(Id and sequence).
Running the procedure p_region with start date and region id ( checking whether id and sequece is exist f_daily_report table).
end loop
The above steps which i have explained needs to achievd thru collections, can anybody helps me out on this.
Note:
1. All the missing jobs wil fal under differnt date rane groups.
2. For second job i.e p_region i have mentioned that it will run based on start date and region id..This job will run on three differnt region id's..We can find the
region id based on by joining f_region and d_region table. It seems that these misisng records belongs to all three regions
Hope u all understand my scenrio. can you please help me out..
Thanks in advance,
Anoo..

Hi,

rather than select statement.. Even though if we can get in simple statement is not advisible in my case..That is the reason why i was looking collections...
Rather than providing data is it possible to how we can proceed in collections.That's like saying you want to write poor code that performs slowly rather than fast and performant code.
Without clear explanations and examples of data and output, there doesn't appear to be a valid reason for using collections. The reason you're not getting many responses on your thread is because you're not explaining clearly what is required with examples.
