Question

I am trying to get the request parameter which has ‘&’ sybol in starting like:-
http://localhost:8080/simple.jsp?my=&234587

On other page I’m getting it like String value=request.getParameter("my");
value.substring(0,4);

I want to get &234, please suggest i am not getting any value.

Thanks,
Ars

Answer 1

In this example you have not one, but two parameters:

1. my
2. 234

234 is not a value here. The & separates query parameters. If you need that ampersand to be part of the value of my, it needs to be escaped in the URL as %26.
