What is claimed is:

1. A method for saving and recovering the state of software in an object oriented software environment, said method comprising the steps of:
(a) recording persistent objects into persistent storage, said recording occurring at times designated by each of a plurality of essential objects;
(b) instantiating a replacement object for each of the plurality of essential objects, based on the
persistent object;
(c) executing a hydrate method within each of the plurality of essential objects;
(d) instantiating replacement non-essential objects; and
(e) generating non-essential values.

2. The method according to claim 1, wherein the step of recording persistent objects further comprises the step of serializing the persistent objects prior to storage.

3. The method according to claim 1, wherein the step of generating non-essential values further comprises the step of making at least one method call on at least one of the plurality of essential objects.

4. The method according to claim 3, further comprising the step of repeating the at least one method call.

5. The method according to claim 1, further comprising the step of configuring the persistent storage into a file system.

6. The method according to claim 1, further comprising the step of configuring the persistent storage into a database structure.

7. The method according to claim 1, further comprising the step of verifying, within each of the plurality of essential objects, whether all of its values have been restored.

8. A system for saving and recovering the state of software in an object oriented software environment, said system comprising:
(a) persistent objects stored within persistent storage, said persistent storage accessible by the
software environment, wherein said persistent objects are stored at times designated by each of a plurality of essential objects;
(b) a recovery manager for instantiating a replacement object for each of the plurality of essential objects based on the persistent object;
(c) a hydrate method within each of the plurality of essential objects, said hydrate method
implemented to instantiate replacement non-essential objects and generate non-essential values.

9. The system of claim 8, further comprising logic within the hydrate method to compensate for changes within the software environment.

10. The system of claim 8, wherein said access to said persistent storage by the software environment is by way of a communications data network.

11. A computer storage medium containing an algorithm for saving and recovering the state of software in an object oriented software environment, said algorithm comprising the steps of:
(a) recording persistent objects into persistent storage, said recording occurring at times designated by each of a plurality of essential objects;
(b) instantiating a replacement object for each of the plurality of essential objects, based on the
persistent object;
(c) executing a hydrate method within each of the plurality of essential objects;
(d) instantiating replacement non-essential objects; and
(e) generating non-essential values.
