Building hashtable for INPUT types dynamically

Question

In my jsp I want to define a method which can build and return a hashtable of all the input types defined inside a form. For example if my form looks like :
<form name="detail_form" method="post" action="">
<input type="text" name="asset_name" size="15" value="ABC">
<input type="text" name="asset_desc" size="45" value="Laptop">
<input type="hidden" name="employee_id_key" value="58975">
<input type="hidden" name="asset_id_key" value="15">
</form>
then my method will be like :
<%!
public Map getCurrentData()
Map paras=new HashMap();
paras.put ("asset_name", "ABC");
paras.put ("asset_desc", "Laptop");
paras.put ("employee_id_key", "58975");
paras.put ("asset_id_key", "15");
return paras;          
%>
Now the problem is :
since the code inside the form can be dynamic (like there can be different number of INPUT types with different names) so I want my method getCurrentData() to be dynamic. That probably means some sort of loop to go through all the INPUT types in the form and storing it in hashtable. But I dont know how to do it in java. Can anybody help me please. Thanks

I am not exactly sure what you mean by "input types" but you could use the request.getParameterMap() method after the form is submitted. So for example you would have your form like <form ... action="nextpage.jsp"> and on nextpage.jsp you could call request.getParameterMap() to create a map of all the paramaters and their values. Here is what I mean...
<form name="detail_form" method="post" action="nextpage.jsp">
<input type="text" name="asset_name" size="15" value="ABC">
<input type="text" name="asset_desc" size="45" value="Laptop">
<input type="hidden" name="employee_id_key" value="58975">
<input type="hidden" name="asset_id_key" value="15">
</form>
then on nexpage.jsp you could say
<% Map myMap = request.getParamaterMap(); %>
Good Luck
