How to validate an email in jsp

Hi everyone, I am developing an web application in which i had to validate a user entered email address. Actually i developed some part of the code in jsp but its not so perfect because when a user enters more than one @ symbol,i am not able to detect it. Also there are some more bugs in it. So can anyone give me a sample code for this validation of an email-id. Also i heard that we have to use some regular expressions for this.Is it true? if so how? i need an idea.

Create an InternetAddress using the email string:
import javax.mail.InternetAddress;
InternetAddress email = new InternetAddress(emailString);or
InternetAddress email = new InternetAddress(emailString, true);If the address is not RFC822 valid, you should get an AddressException. If you set the address using the InternetAddress.setAddress(String s) method, then call validate(), which wil throw an AddressException on an invalid address.

How to Validate Multiple email address in spry?

How to validate multiple email address in spry framework?
Spry validate text field can validate one email address only,
if I the text field is for multiple emails, how can I validate
it?

Hello Jackson,
The Spry Textfield was designed to work with the normal work
flows that people currently use in most of the forms on the web. We
tried to prevent any email injection method in the forms therefore
the validation was designed to stop any multiple email insertion.
In case you want to insert multiple emails you'll have to
disable the default email validation and create your own validation
function, more flexible. You can see a
sample
we did for the custom validation trying to validate a password
strength and confirm the password.

How to validate an email address against free domain users

Hi all,
I want to validate an email address so that only users of non free domains (let's say other than yahoo, hotmail, gmail, etc) can create an account in my apex application.
I want to place a validation on the "Registration Page" but I am not sure how to proceed from then on :(
Does anybody know how I can do this ?
Kind Regards,
Ana-Maria

Hi Ana-Maria,
You can do this on two places. You can do it on the client (using javascript) or you can do this on the database (using a trigger or a check constraint). The best way is to do both.
Use something like this for the javascript bit:
<script type="text/javascript">
function checkemail(){
var email = $v('P4_EMAIL');
//get index of @
var x = email.indexOf('@');
//get the string behind @
var behind_amp = email.substring(x+1, email.length);
//get the index of the .
var y = behind_amp.indexOf('.');
//filter out the provider
var provider = behind_amp.substring(0, y);
var result;
// set all wrong providers in this case
switch(provider){
    case 'hotmail': result=false;break;
    case 'yahoo': result=false;break;
    case 'gmail': result=false;break;
// Check the result
if (!result){
    //The provider is bad
    alert(provider + ' is not allowed!');
    //Keep the focus on the email field
    setTimeout(function(){$x('P4_EMAIL').focus();}, 5);
</script>Set the event to the onchange of the email field (in HTML Form Element Attributes):
onchange="checkemail();"Hope this helps,
Greetings Rutger

Hi,
Create an validation on EMAIL item and select Regular Expression as a validation method.
Write the below coding in the regular expression validation method.
^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*\.(\w{2}|(com|co.in|in|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum))$

How to validate a email address using Validation Pattern?

Hi,
is there any document for Validation Pattern? i m looking for a way to validate email addresses in my form.
it's going to be something like * @ .
i have no idea of how to do this, or maybe validation pattern is no good? use java script instead?
any advice is appreciated!
thanks.

Hi erv2,
You just need to place this script in the "exit" event of the field that u r using for email address.
var r = new RegExp(); // Create a new Regular Expression Object.
    r.compile("^[a-z0-9_\\-\\.]+\\@[a-z0-9_\\-\\.]+\\.[a-z]{2,3}$","i");
if( this.rawValue == null || this.rawValue == "")
else
var result = r.test(this.rawValue);
if (result == true) // If it fits the general form,
     true;
else
      xfa.host.messageBox("Please enter a valid email address ");
      this.rawValue = "";
      false;               // fail the validation.
Thanks
Amita

How to Validate Data from a JSP form

[newbie]
From a netui:anchor, I call a data entry form (dataEntry.jsp). It contains 5 textboxes created using netui:form and netui:textbox.
The user enters the new account info and clicks the submit button, a form bean is populated and passed back to the controller which calls a method to update the database. This all works well. At least it did, until I found that I could enter control characters into the form... So, this brought up the issue of data validation.
I would imagine there is a standard way to validate form data. (like checking a value is numeric or alpha, has a specific length or to apply a regex or edit mask prior to insertion into a database...)
Is it generally done within the jsp?, the form bean? or in the controller? The latter 2 would be java, I suppose. If it's in the jsp, are there jsp tag libraries for that?
Any direction would be most appreciated.
Mark
If I should be on another forum/newgroups (perhaps one for amateurs, please let me know... :>)

I believe I found the answers to my questions in some Beehive docs. I'll follow up if I have others... Mark

How to validate the email

Hi all
i have a text input contains email
while save the record i need to check the filed that is valid email or not
at least one @ and .(dot) symbol should check
how its posible
Regards
Sree

Hi,
There are lot of regular expressions available on net. You can choose as per your requirement.
Following is an example which checks most of the email types.
public boolean validateEmail(String email) {
String regEx = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?";
//Set the email pattern string
Pattern p = Pattern.compile(regEx);
//Match the given string with the pttern
Matcher m = p.matcher(email);
//check whether match is found
boolean matchFound = m.matches();
return matchFound;

How to validate a session object in jsp?

Hi All,
i am facing a problem.The problem is how to validate the session object object in jsp.I have written a java script by using a defined function as setInterval and has given 5 mintues if the user is idle and will show a pop up menu before time out the session but in case of page active still this pop up menu is coming. The java script as follows.
function SetTimer(){
     //How long before timeout (should be a few minutes before your server's timeout
     //set timer to call function to confirm update
     if(timeoutMinutes)
     timerObj = setInterval("ConfirmUpdate()",60000);
function clearTimerFn(){
          timerCount = 0;
          clearInterval(timerObj);
          //timerObj = setInterval("ConfirmUpdate()",60000);
function ConfirmUpdate(){
     //Ask them to extend
     if(confirm("Your session is about to expire. Press 'OK' to renew your session.")){
          //load server side page if ok
          var url = "ajaxSessionchecker.do?sessionvalidate=sessionvalid";
          LoadXMLDoc(url);
And in jsp i am calling this js function as
<%session=request.getSession(false);
          if(session.getLastAccessedTime()==60000){ %>
          <script type="text/JavaScript">
     clearTimerFn();
</script>
<%}else{
session.setMaxInactiveInterval(-1000);} %>
could you pls help me out?

The reason for doing this is when ever i come to this user.jsp from account.jsp with a different account number this user.jsp is not refreshed and i still
see the same old user.jsp for the previous account that i naviated before. Also please let me know if there is any other approach to acheive this taskDoes refreshing the page by pushing F5 solve the problem?
If so, then the browser is caching the page, despite your attempts to stop it.

How to validate Email Address in HTML DB Application

Hi,
I have delevoped one Employee Login Details form in HTML DB. But i am unable to validate that email address as i find html db is not supporting String functions like indexOf(char c), substring(int) ect. So please can anybody help me to know how to validate email address that it has @ and . symbol or not.
Thanks in advance.

user529382,
You may be able to use Regular Expressions instead, if you do a search in this forum for 'regex' you should find a few hits.
While I agree that using a regular expression is a great way to verify that the user has entered an email address that conforms to the regular expression rules, it is still nothing more than that....conforming to the regular express rules.
The only way to 100% confirm that an email address is 'valid', is to actually send an email to it, so what I tend to do is to get the user to enter their email twice (in a user registration screen for example), that way you can minimize the chance of 'typos', then send out a 'verification email' that the user has to click a link on to verify they have received it (I'm sure you've seen this type of system before), only when the confirmation is received would I then make the account 'active'.
Hope this helps.
