Hello, I am also working on the similar type of the problem. I am having forms as below in my application.
- A hidden div containing a message and a small animated gif image of an hourglass that appears to validate the form.
- One target to another hidden div empty
- Validation of the form by post on a servlet
- The form is validated via javascript

If anyone knows the solution then reply about the same to me also.

Hello, I think if you make use of the code below then you will able to get the solution for your problem:

Code:

var one;
function fun()
{		
var url = "<% = oneuest.getContextPath ()%>/ ServletDoGet";
if (window.XMLHttpRequest) 
{ 	    	
one = new XMLHttpRequest();
try 
{
one.open("GET", Url, true);
one.onreadystatechange = Function()
{
if (one.readyState == 4)
{
processStateChange();
}
}
} 
catch (e) 
{
alert(e);
}
 one.Send(null);			        
 } 
else if (window.ActiveXObject) 
{ 
one = new ActiveXObject("Microsoft.XMLHTTP");
if (one) 
{
one.onreadystatechange = ProcessStateChange;
one.open("GET", Url, true);
one.Send();
}
}

Hello, it is quiet a simple thing to do which you want to do. If you want to view an image type hourglass in java then you must need to make use of the code below:

Code:

cmp.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));

And after that if you want to move to the regular or default image of the cursor then you just need to make use of the code below:

Code:

cmp.setCursor(Cursor.getDefaultCursor());
