How do I convert a Vector to be passed into the session

Question

Hi I have a vector in a JSP that I need to pass on to a second JSP. I use the following command to do that just as I pass normal other strings:
session.setAttribute("MyVector",vecData);
But the follwoing error is been thrown by Tomcat.
Incompatible type for method. Can't convert void to java.lang.Object.
out.print(session.setAttribute("ResultsSet",set));
^
I guess I have to convert it explicitly into an object and then how do I do that? could someone please help me fast on this?
if this doesn't work is there some other way to send this vector to my other page? I am currently sending enough strings using the above method, but for Vectors it doesn't seem to work though I am told that a session object can carry any object unlike the request object that carries only strings. Please help!!!!

Hi Calin thank you so much for taking ur time to help me with my problem.
well let me explain my requirement fully in detail. JSP1 has a form on it for the user to fill in. its in the form of a table with multiple rows. say as in entering product details one after the other in an invoice.
I want each of these rows taken in and passed into JSP2.
What I do is pack each row of the table into a hashtable using a 'for' loop.
Then I add each record (within the 'for' loop) to a Vector. After the 'for' loop, outside of it, I set this Vector to the session as :
session.setAttribute("RecordSet",vecRecordSet);
Well let me copy paste and extract of the coding from my source which shows what I have done.
Vector set=new Vector();
for (int i=0;i<Integer.parseInt(request.getParameter("NoOfRecords"));i++)
Hashtable Record=new Hashtable();
               Record.put("ReminderStatus",ReminderStatus);
               Record.put("CustomerNo",CustomerNo);
               Record.put("CustomerName",CustomerName);
               Record.put("Address",address);
               Record.put("ContractNo",ContractNo);
               Record.put("MachineID",MachineID);
               Record.put("ModelNo",ModelNo);
               Record.put("Description",description);
               Record.put("SerialNo",SerialNo);
               Record.put("ContractValue",ContractValue);
               Record.put("NoOfServices",NoOfServices);
               Record.put("ContractStartDate",ContractStartDate);
               Record.put("ContractEndDate",ContractEndDate);               set.add(Record);
     session.setAttribute("ResultsSet",set);//SHERVEEN
well don't worry about the for loop condition up there cos it works for the main functionality that exists within the for loop. but what seems to go wrong is when I add records to the hashtable and when I pack it to the Vector "set"
I hope I have not done something wrong as a principle over here.
And btw the error that I showed u before, is pointed at a row which exists in the file that is generated when compiled. the out.println part is generated in that file during compilation and I don't know why.
I hope I have given u information for u to make some sense of my requirement and thank u a million once again for ur effort to help me out. I am grateful to all of u.
