Subject RE: request.getParameter Error when "%" contained in parameter value
Date Mon, 16 Feb 2004 18:15:32 GMT
The same error occurs for "%25". If I put a "%" anywhere in the
parameter I get a crash. "4%" would pass a parameter to query everything
starting with 4 in my example.

Why don't you use: http://website/findnaics.jsp?code=%25
