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.

Everything is working perfect except for & + %. I am converting parameter to httpparam so & value is %26 + value is %2B and % value is %25. / value is %2F all others are working fine. I am having no trouble with other special characters but as I include & + % 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 & 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 < or > or >< or <> are working fine and I can not restrict entering special characters as it is requirement

could any one help me Thanks in advance.

Welcome to Stackoverflow. Please pay more attention on formatting your question, separating code sections, grammar, etc. to make it more readable and easier for others to answer. - Neeku
?param1=%2B&param2=%2B You don't want to encode the & between parameters, only the ampersand inside a parameter value. Is that the question? - developerwjk

Ordinarily web browsers automatically perform URL encoding on form fields, however you can perform encoding and decoding yourself using the appropriate classes. You might want to check out:
