Which method can replace parseQueryString()

Hi,
javax.servlet.http.HttpUtils.parseQueryString(java.lang.String s) which is used to parse a query string passed from the client to the server and builds a HashTable object with key-value pairs has already been deprecated. I got the warning when I compiled the code. What's the method can replace parseQueryString() which can provide me the same functionality ?
many thanks.

From the API Docs for HttpUtils
Class HttpUtils
java.lang.Object
|
+-javax.servlet.http.HttpUtils
Deprecated. As of Java(tm) Servlet API 2.3. These methods were only useful with the default encoding and have been moved to the request interfaces.
This means that you will need to use the HttpServletRequest interface methods.

there is a statement.
"Now, the COUNT function does not need to retrieve all of the fields from the table (ie: employee_number, employee_name, and salary), but rather whenever the condition is met, it will retrieve the numeric value of 1. Thus, increasing the performance of the SQL statement."And have you ever tried it? Or do you simply blindly believe everything you read? And what sort of "authority" is "tech on the net"?
P.S. A quick test on Oracle (and you must do each query at least twice throwing away the first result, as Oracle always caches things which will have an effect, and averaging the remaining attempts).
count(*) -- 1 min 17 secs for 35,311,978 rows
count(1) -- 1 min 19 secs for 35,311,978 rows
Edit: And the table has 46 columns.

IMAC 2010 which HDD can I use to replace the malfunctioned Seagate Barracuda 7200.12 1TB?

iMAC 2010 which HDD can I use to replace the malfunctioned Seagate Barracuda 7200.12 1TB?

After doing a bit more research, the 2010 iMacs do appear to have a third cable connecting to the hard drive, for the internal temp sensor. This would appear to be the block of 8 pins that are on almost all drives, but they are normally intended for jumpers. Unfortunately I was unable to find any documentation or specs that would indicate this pin block connects to the internal temp sensor on either standard (non-Apple) WD Black or Seagate 7200.12 drives.
I did find some info that may be of some use:
WD: Where to connect an external temperature sensor to a Serial ATA or EIDE hard drive.iFixit: Replace the hard drive, how do I connect the hard drive thermal sensor?
Apple Technician Guide: iMac 2010 27" (mid-2010)
Various discussion threads I found through google searching indicated some people succeeded with installing an external temp sensor on the body of the drive.
Sorry I couldn't help more.

IPhone4S! Which parts can I replace?

I dropped my iphone4s. . .
So I want to know which parts can be replaced?
I heard camera, battery, back cover, vibration motor can be possible.
Do U know how much do they cost to exchange in us.

"I want to know which parts can be replaced"
I'd think that you'd be more interested in what parts you'd need to fix the iPhone. There are many teardown videos for the iPhone, and most parts can be obtained over the internet through third-party vendors.

How can i know in which method i am?

I would like to know ( for debugging reasons ) in which Method the execution code is!
Like the printStackTrace() which indicates:
- package
- class
- method
- line
at mypackage.myclass.mymethod4(MyClass.java:40)
at mypackage.myclass.mymethod3(MyClass.java:30)
at mypackage.myclass.mymethod2(MyClass.java:20)
at mypackage.myclass.mymethod1(MyClass.java:10)
at java.lang.Thread.run(Thread.java:484)
Does anybody knows how to do this?

This will return the calling class.method() of a class.
public static String getCallingClassMethod() {
     try {

          if (System.getProperty("os.name").startsWith("Windows"))
               n = 6;
          // loop through all the crap that comes before our calling method
          for (int i = 1; i < n ; i++){
               stackInfoParser.nextToken();
          // get our calling class.method
          String returnString = stackInfoParser.nextToken().trim();
          // get rid of the garbage

Shortcut Method for Replace Pages dialog box

What is the keyboard shortcut method for bringing up the Replaces Pages dialog box. I use Replace Pages function a lot in preparing PDF documents and need a faster method than using Mouse on Tools right sidebar. I note that shortcut key for inserting pages is Cntrl-Shift-I -- what is shortcut for Replace Pages. In previous Acrobat 9, I could use alt-DNR, which brought up Replaces Pages dialog box via the menu, but there no longer is a Document item in the menu bar -- it has been removed. Please, this is VERY important to me. Any help will be greatly appreciated.

Thank you for your quick reply. You have confirmed my worst fear. But anyway -- going forward ..... in your opinion, what is the best way to get information to Adobe on ideas for improvement so that future version or maybe even an update for this version could have something like what I need, that is, shortcut key for Replace Pages -- or ability to access customized quick tools via keyboard, etc. Is there someone keeping a list of these things that I can write to? Thanks again. (And don't worry, I won't extend this discussion past your hoped-for reply.)

I recently uploaded 10.8, but I have a number of VALUABLE old files which I can no longer read because "power PC applications are no longer supported. How can I retrieve them"?

Here is a post I assembled for another with a similar problem:
Unfortunately you got caught up in the minor miracle of Rosetta. Originally licensed by Apple when it migrated from the PowerPC CPU platform that it had used from the mid-1990's until the Intel CPU platform in 2006, Rosetta allowed Mac users to continue to use their library of PPC software transparently in emulation.
However, Apple's license to continue to use this technology expired with new releases of OS X commencing with Lion (and now Mountain Lion). While educational efforts have been made over the last 6 years, the fact is that Rosetta was SO successful that many users were caught unaware UNTIL they upgraded to Lion or Mountain Lion.
Workarounds:
1. If your Mac will support it, restore OS X Snow Leopard;
2. If your Mac will support it, partition your hard drive or add an external hard drive and install Snow Leopard into it and use the "dual-boot" method to choose between your PPC software or Lion/Mt. Lion;
3. Upgrade to an Intel compatible versions of your software, or find alternatives that will open your data files;
3. Install Snow Leopard (with Rosetta) into Parallels:
[click on image to enlarge]
Full Snow Leopard installation instructions here:
http://forums.macrumors.com/showthread.php?t=1365439
NOTE: STEP ONE of the instructions must currently be completed on a Snow Leopard or Lion Mac and the resulting modified Snow Leopard.cdr install file can then be moved over to your Mountain Lion Mac for completion of the remaining steps.
NOTE 2: Computer games with complex, 3D or fast motion graphics make not work well or at all in virtualization.
