Passing An Array trough JSP pages

Question

Hello there, what i am trying to do here is pass an array that i have created in one.jsp to another.jsp.
So if i want to pass a single variable say Long (for example) i would do something like that:
one.jsp
Long pairId = new Long(15);
session.setAttribute("pair", pairId);and to retrive it from another.jsp
Long pairId = new Long(session.getAttribute("pair").toString());Now instead of Long pairId if i create a Long[] pairArray and want to move it from one.jsp to another.jsp what should i do? Please let me know if this is possible and if not, please suggest an alternative way to go arround this problem.

Answer 1

actually i didnt read what you write properly, so if i can do it, how should i do it?
if i do something like that
one.jsp
String[] lArray =...
session.setAttribute("pair", langArray);and try ratreaving it from another.jsp like that:
String[] langArray = session.getAttribute("langArray").toString();i am getting the following error:
C:\Programs\internet\jakarta-tomcat-5.0.28\work\Catalina\localhost\myapp\org\apache\jsp\resources\questionsmanager\addQustion_005fSubmit_jsp.java:66: incompatible types
found : java.lang.Object
required: java.lang.String[]
String[] langArray = session.getAttribute("langArray");

this means that the array is casted to Object and i need to cast it buck to a string array.... But how am i suppose to do that???
