hi helpers,
i'm trying to read an array from jsp in to java(servlet) page
the code is
JSP CODE (readingcheck box values):

String select[] = request.getParameterValues("sel"); 

if (select != null && select.length != 0) {

for (int i = 0; i < select.length; i++) {
out.println(select[i]);

its working ok!

JAVA CODE(reading array values):

String select2[] = request.getParameterValues("select"); 
for (int i = 0; i < select2.length; i++) 
{
System.out.println(select2[i]);
}

the above java code didnt worked.

i also tried this

String[] select= new String[100];
for (int i = 0; i <10 ; i++)
{
select[i] = request.getParameter(select[i]);
System.out.println(select[i]);
}

this didnt worked too
is there any other way to read array values from jsp page?
where am i wrong?

thanks,
BeanBoy !

If the url is this : "/jspservlet?name=blah&myArray={1,2,3}" (the curly brackets would be replaced with the correct url encode for brackets which would be %something), then using request.getParameter("myArray") would return the array.

its working ! thanks

Pleasure, glad to help
