Passing checkBox value to another servlet
hey! there,
I am pretty new for java servlet. I am having trouble for passing the name of the checkbox in another servlet.
The situation goes like this.
I have a page where dynamically checkboxes are created based on the number of accounts associated with the user in the database. I have pulled out the information from the database to display in the table where one column is for check box. Now I have to pass the name of the checkbox to the another servlet where I have to ckeck whether the check box value is false or true.
If the number of check box is static, I could have given the specific name which can be passed to the next servlet easily but the I don't know how many checkbox it comes up in the table.
Since I am new to Java, I could not figure out how to name that ckeckbox in the page and pass it to the another servlet page.
Note that the pages are entirely Servlet.
Any help would be heartly, appriciated

hi beg,
One way to this is
--
Servlet code
for i = 1 to noOFUSers
String x = "<INPUT TYPE=CHECKBOX NAME='user' "+i " >"
put x in screen
-
The HTML generated should post to 2nd servlet
IInd servlet code
Enumeration paramNames = request.getParameterNames();
while(paramNames.hasMoreElements()) {
String paramName = (String)paramNames.nextElement();
if(!paramName.startsWith("user"))// same string as checkbox name
{
continue;
}else{
String paramValue = request.getParameterValue(paramName);
// do u r processing on paramValue
}
}

Another way is to use the same name attribute for all of them
<INPUT TYPE=CHECKBOX NAME='user' >
Then, at the second servlet, call
String[] users = request.getParameterValues("name");
and iterate over the string array.
