Storing array(or other data structure) in a session object

Question

hi wise ones
to minimise my calls to a database I would like to store the information retrieved from a ResultSet in an array and then store this in a session object, retrieving it with getAttribute("nameOfArray"); when I need it.
I have tried to print the object contents to test what is happening but am getting a[b] [Ljava.lang.String;@11d646c[/b] response which is something, but not what I expected.
Is using a session the right way to make the information available to all servlets? If not what other method is appropriate?
thank you

Answer 1

thanks for your comments Annie & MLRon. I have tried both suggestions but am still hitting problems
the usual method to get the elements results in my compiler complaining that sessionINFO is an object and .length cannot be applied to an object.
for (int i = 0; i < sessionINFO.length; i++) {
                   out.print(sessionINFO);
               out.print("<BR>");
An array IS an object though?
I have used Arrays.asList(sessionINFO) and get another compiler error stating that java.util.Arrays cannot be applied to an object
I took my variables from the ResultSet and converted them all to Strings and put them into a String array
int bankIDLogin=customerResults.getInt("id");
                               //convert to String for array
                               String bankIDLoginSTR = String.valueOf(bankIDLogin);
                              String passwordLogin =customerResults.getString("password");
                              String accNo=customerResults.getString("number");
                              float accBal=customerResults.getFloat("balance");
                              //convert to String for array                              
                              String accBalSTR = String.valueOf(accBal);
                              //put info into array
                              String[]customerDetails={bankIDLoginSTR,passwordLogin,accNo,accBalSTR};then I put that array into the session object
                    HttpSession session =req.getSession(true);
                    session.setAttribute("id",bankID);
                    session.setAttribute("customerdetails",customerDetails);In a separate servlet I called the session object
Object sessionINFO = session.getAttribute("customerdetails");How can I get the original array out of this object?
What should I do if more than one result set is created and I need to create two session objects with customer details, (one customer has two accounts)? multi dimensional array?
