Try using the setAttribute() and getAttribute() methods available on the
ServletContext or HttpSession objects. As long as the object you store as
an attribute of the servlet context or user session is serializable, this is
a great way to share data between a synchronous servlet-to-servlet process
where one servlet delegates control to another, or asynchronous, individual
servlet processes where objects need to be persisted for longer than the
request/response cycle.
These are very easy to use and only require you to cast the getAttribute()
return value back to the type you need, since it returns a generic Object
when deserialized.
e.g.
SomeObject sObject = new sObject(...);
httpSession.setAttribute("someObject", sObject);
...
SomeObject persistedObject = (SomeObject)
httpSession.getAttribute("someObject");
