Sending More than One Value for an Associated Name


Have you ever wanted to send more than one value for an associated name by passing values to a Servlet or JSP using a name-value pair? A simple way to do this is to pass a string array for an associated name.

Here is the HTML code that does this (it can be done in the same way using JSP):
 
………
………
<Input type=”text” name=”test” >
<Input type=”text” name=” test” >
<Input type=”text” name=” test” >
<Input type=”text” name=” test” >
<Input type=”text” name=” test” >
………
………

On submitting the form to a Servlet or JSP the name “test” will contain more then one values (in this case 5 values).

In the Servlet or JSP, the following piece of code will get the all the values associated with the name:
  
String test []=request.getParameterValues (“test”);

“test” has a string array or returns null if the values are not received from the request.
