title: how to pass special characters like & + % in jsp in URL
body: <p>I am new to jsp.
  I am taking user input(name) in a textfields. This input is saved in xml file.
  I am using name attribute as a parameter and sending this parameter to another jsp file so that user can add child nodes to the given parameter.</p>
  
  <p>Everything is working perfect except for <code>&amp; + %</code>. I am converting parameter to <code>httpparam</code> so <code>&amp; value is %26 + value is %2B and % value is %25</code>. <code>/ value is %2F</code> all others are working fine.
  I am having no trouble with other special characters but as I include &amp; + % it is giving me empty value and not null in other jsp hidden fields.and thats why I am not getting any value from String name = request.getParameter("name");this statement.
  Even my URL looks like jsp?name=%25 for % parameter. and ...jsp?name=%26 for &amp; parameter 
  and ...jsp?name=%2B for + as a parameter
  My xml file has ISO-8859-1 encoding   
  problem2) if I send parameter as  (which is name given by user) its also empty and not null but alone &lt; or > or >&lt; or &lt;> are working fine
  and I can not restrict entering special characters as it is requirement </p>
  
  <p>could any one help me 
  Thanks in advance.</p>
