Static collection - interesting

Question

We are having multiple financial servers running in a single JVM, the requirement is to maintain a hashtable in some object so that it may be accessed by another objects without passing refernce to it.
For example:
Class Example_1{
static Hashtable cache = new Hashtable();
public void meth1(){
cache.put("0001","Sun Microsystems");
Class Example_2{
public void meth1(){
String companyName = (String) Example_1.cache.get("0001"); // breakpoint (1)
Actually when we are trying to do this, an empty Hashtable is being returned at breakpoint (1). We want to use core java and do not want to use flat file or db to store the hashtable data. How can I maintain a Collection in one ojbect such that it may be available to the other objects without passing the reference.

Answer 1

Ahh...Thanks ...it works.
-->Just in case someone else encounters the same problem, let me summarize a design pattern here:
In case you have multiple processes running in your application and you need to maintain a central threadsafe repository/cache.
1) Make a class( MyAppLoader) for starting all processes and creating the Context( or cache),
2) MyAppLoader creates the Context object and places the application data in its static members( like Hashtable).
3) MyAppLoader should then create multiple threads and start individal procces
4) Individual processes can then access the Context, the choice of using a Context rather than a db of flat file makes the system real time, faster and a cheaper solution. Also Hashtable collection objects are threadsafe.
Thanks once again.
