How-to clear the session values from the jsp page?
session.invalidate() . But you need to refresh page to take effect. Note that generally that the session truly ends only when the browser window closes. The six most commonly used methods to invalidate a session are • Calling HttpSession.setMaxInactiveInterval(int secs) method, explicitly setting how many minutes the session will last. • The session will automatically be invalid after a certain time of inactivity (Tomcat default is 30 minutes). You need to remember that this 30 minutes is not a hard and fast rule for all servers. It might vary from one server to another and is configurable. So you can have it configured to last 25 mins in your server and I can have it to last 20 mins. • The user closes all browser windows. Note that, here the session will timeout rather than directly triggering a session invalidation. • The session will expire when it is explicitly invalidated by a servlet by calling invalidate(). • The server is stopped or crashes. Note that this event might not trigger a session invalidation. A Web container that permits failover might persist the session and allow a backup Web container to take over when the original server fails. • You can set the default timeout in the web.xml file ().
Will standard sheets still fit my bed if I use a mattress pad?
Yes, but these days most "standard" sheets are labeled "deep pocket." If you have a thick mattress topper, you'll need "extra deep pocket" sheets. It's best to measure your mattress with the topper in place, then look for sheets with the mattress depth on the package. If all else fails, just buy flat sheets and make your bed Hotel style, tucking the corners.
What makes 21 a composite number?

What is the maximum size of a file that can be uploaded using PHP and how can you change this?
By default, the maximum upload size in PHP is 2MB. This is kept in the php.ini file. To allow for the upload of larger files you have 3 options.Change the php.ini file. You're going to go into your php.ini file and look for the lines: memory_limit = 8Mpost_max_size = 8Mupload_max_filesize = 2MYou want to change the upload_max_filesize. Make sure that you don't exceed the post_max_size (if you do, then change them both.) Also, it's a good idea to make sure that memory_limit is always larger than post_max_size. (This applies to all these solutions.)After making changes to php.ini, your webserver will need to be restarted.Assuming you can't get into php.ini, you're using Apache, and you're running PHP as a module, you can use an .htaccess file. That file should contain the following lines: php_flag file_uploads Onphp_value memory_limit 8Mphp_value post_max_size 8Mphp_value upload_max_filesize 2MYou put the .htaccess file in the root web folder, and it will apply to all the folders beneath it. If you do this and the server gives you a HTTP code 500 "Internal Server Error" then you aren't running Apache as a module and you can't do it this way. If it doesn't so anything, it's possible that you don't have the permissions to overwrite the Apache config via .htaccess.Finally, if all else fails, you can attempt to add a php.ini file to the webroot. PHP should find this ini file and abide by it. You don't need to copy every setting (anything not here is still in the original.) So your file should look something like this: [PHP]; Whether to allow HTTP fileuploads. file_uploads = On; Maximum amount of memory a script may consume (8MB)memory_limit = 8M; Maximum size of POST data that PHP will accept.post_max_size = 8M; Maximum allowed size for uploaded files.upload_max_filesize = 2MIf that technique fails, then it's time to admit defeat and call your hosting provider or IT guys and ask, politely, that they fix this for you.
What is 5 percent of 5 gallons?
5 x 5% = on your calculator gives you 0.25 so it's 1/4 gallon or 1 quartThink about this, 10% of 5 is 0.50 and then cut that in half again to give you 5% so it's 0.25.You can also do a proportion. 5 gallons = ? gallon/ 100 % = 5%- Sorry don't know how to draw a fraction bar hereAnyhow, I do a horizontal number 8 or the infiniti sign to do my proportions math- Just like a number eight race track for race cars.Start line/ Finish line-I want to finish where the question mark is so I start under it. I first multiply, 5 x 5 and like a race car driver go around the curve towards the 100 and divide. Then drive up to question mark which is you Finish line with the Answer. 0.25I use this method when comparing anything.If all fails, think in terms of MONEY! That helps.....

What is throw keyword in java?
The throw keyword is used from within a method to "throw" an exception to the calling method. In order to throw an exception, the method signature must indicate that it will throw an exception. For example: public void foo() throws Exception { } When you want to actually throw the exception, you can do it a few different ways: throw new Exception("Exception message"); or from within a catch block ( catch(Exception ex) ): throw ex;
