Issue
I have an application which makes lot of multiple servlet calls. How do I make sure that till a particular servlet X processing is completed no other servlet instance of Y, Z is called.
A SingleThreadModel or synchronization will make sure that only one thread per servlet is called. However that may not work on more than one servlet.
Solution
Use Callback mechanism for each server calls. Onsuccess of first server call you can call second.
