How to get an ArrayList Object in servlet from JSP?

[edwardmraj]

hi all

please give the solution for this without using session and application...


In test1.jsp file
i am setting values for my setter methods using <jsp:usebean> <jsp:setproperty> tags as shown below.

After that i am adding the usebean object to array list, then using request.setAttribute("arraylist object")


---------Code----------
<jsp:useBean id="payment" class="com.common.PaymentHandler" scope="request" />

<jsp:setProperty name="payment" property="strCreditCardNo" param="creditCardNumber" />
<%-- <jsp:setProperty name="payment" property="iCsc" param="securityCode" /> --%>
<jsp:setProperty name="payment" property="strDate" param="expirationDate" />
<jsp:setProperty name="payment" property="strCardType" param="creditCardType" />
<%--<jsp:setProperty name="payment" property="cDeactivate" param="deactivateBox" />
<jsp:setProperty name="payment" property="fAmount" param="depositAmt" />
<jsp:setProperty name="payment" property="fAmount" param="totalAmtDue" /> --%>


<jsp:useBean id="lis" class="java.util.ArrayList" scope="request">
<%
lis.add(payment);
%>

</jsp:useBean>

<%
request.setAttribute("lis1",lis);
%>
-----------Code in JSP-----------------

In testServlet.java

i tried to get the arraylist object in servlet using request.getAttribute

But I unable to get that arrayObject in servlet.....

So if any one help me out in this, it will be very helpfull to me..

You can't set properties in the request in a JSP page then access them in the servlet. As soon as you submit the form or change pages, its a new request and your properties aren't there. You either need to pass them in the URL or in a form submission post or get.

Jeffro's mainly correct. If you've ruled out using the session and application objects, you've ruled out the simplest way to do this. You could work with the Response object, and then pass that on to the servlet using the "forward()" method. At least I think you can - I haven't done it before. Give it a shot and see if it works.
