now, while displaying the form generate some random number, or take the current time in millis or whatever. Put that number in a hidden field. Insert that unique number along with the real data into the database, but before you do check if the number already exists. If it does you can be pretty sure this is a resubmit of the same data, so don't allow it. This is one way of many to prevent resubmission of existing data.
A good way to prevent a refresh from resubmitting altogether is to do a redirect to a result page right after you deal with the POST request. When the user presses refresh then, he/she will refresh the redirect and not the form submit.

Drudgereport includes JavaScript code that refreshes the page. You could disable JavaScript for the drudgereport site, that will stop it from refreshing. You can do that by installing the [https://addons.mozilla.org/firefox/addon/4922/ YesScript] extension which allows you to block JavaScript on sites that you specify.

How To Customize displaying of JSP page From Backing Bean

I would like to customize the displaying of jsp page from backing bean based on user Roles
For example
- if the Role is Admin then backing bean should display Admin.jsp
- if the Role is Guest then backing bean should display Guest.jsp
Any pointers/suggestions will be highly appreciated
Regards
Bansi

Thanks to all for providing thoughts
I wanna make it more Dynamic. In the sense
"Backing Beans should drive the rendering of first jsp page in the application " and not jsp page driving the backing bean or not to put some kind of hard coding in jsp page to see if its admin user then display certain set of UI Components or certain set of other UI components for other users.
As we have atleast 10 different Roles and there can be Composite Roles i.e. combination of two roles. In this case how does the Backing Bean drives the rendering of jsp page?

How can I stop my home page from opening OVER a page from a link I just clicked on?

If I click on a link from an email, Firefox always opens 2 pages with my home page (Google) covering up the page I clicked the link to go to. How can I stop it from doing that?
== This happened ==
Every time Firefox opened
== I think since I got the most recent upgrade (3.6.7)

There's a good chance this is related to a bug that kicks in when you do not have Flash running in any tab and you open a new window to a page that does use Flash: suddenly, the previous window (typically the one from which you launched the link or bookmark) comes back to the front.
The details are in this recent thread: [https://support.mozilla.org/questions/955659 Opening New Windows and Shockwave Flash].

How do I stop the new Pages from updating the old Pages? It is automatically updating, but I don't want it to because it's horrible!!!

I downloaded the new Pages, Keynote, and Numbers, but they're horrible so I deleted them. Now they keep trying to update my old iWorks. I don't want them they are horrible!!! It is automatically updating (I don't have it set to automatic update), so I have it paused, but I don't know how long that will last before they finish the update. Apple, what are you doing to your loyal customers? You are making inferior software and forcing it on us. Why?

Peter,
Luckily it had stopped trying to upgrade overnight, but your suggestion definitely helped. I checked in the System Preferences and, sure enough, I had the auto-upgrade checked for regular programs but not apps. So, it was doing what I told it, even though it wasn't what I wanted! I am very thankful that I get to stay with my Pages 4 for now. I love my Mac because it has always been so intuitive, searching for what I needed was fairly easy. Unfortunately, some of the new upgrades of late don't fit that bill. Pages 5 has some work to be done before I will feel comfortable switching. Thank you for your help!
Now, any idea why my Calendar has frozen with the message "Moving calendars to server account..." ever since I downloaded Maverick? I have had to do a force quit for the last two nights to get it to shut off so I can turn off my computer. The swirling candycane of death accompanies this message. I would be glad to undo whatever I have done....if I only knew what that was!

How do I stop my home page from changing

Despite setting my Homepage to BT Yahoo, every time I restart Safari it resets the home page to the Apple website. Also, having customised my toolbar i.e. added the homepage, top sites, new tab etc icons they are also gone on restarting Safari.
This seemed to happen after I loaded McAfee security, but I have now uninstalled this but the problem persists.
Any suggestions?

Back up all data now.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. If none of this is meaningful to you, you don't need to worry about it.
Step 1
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:20 ~ $_ ; chmod -R -N ~ $_ 2> /dev/null
Be sure to select the whole line by triple-clicking anywhere in it. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select Utilities ▹ Terminal from the menu bar. A text window opens.
In the Terminal window, type this:
resetpassword
That's one word with no spaces. Then press return. A Reset Password window opens. You’re not going to reset a password.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select  ▹ Restart from the menu bar.

How do I stop last web pages from auto loading in Safari?

I find the feature of Lion that auto-loads previous web pages (and previous open applications) annoying. I want to stop this function. I see the checked box that asks if I want to re-open applications when logging out but I want the default to be to NOT re-open the apps. I equally dislike the auto-opening of previous web pages in Safari. I know that I can clear my history but what I want is for my homepage to open when I run Safari and not the last page viewed. Any solutions?
Found this for Safari in the forums...
Go to terminal and type in the following:
defaults write com.apple.Safari ApplePersistenceIgnoreState YES
If you decide that you rather have the new resume behavior, execute the above commands but change YES to NO.
You can also do the same for Preview:
defaults write com.apple.Preview ApplePersistenceIgnoreState YES

iDrifter: The full command is:
defaults write com.apple.Preview ApplePersistenceIgnoreState YES
I was having the same problem and this is what I did:
1) Closed Safari
2) Changed the setting (mentioned) above in System Preferences
3) Enter the "defaults write ..." command into Terminal.
Now whever I launch Safari it does not load any pages.
