How do you make servlet thread safe?

[Kishan]

Servlets are multi threaded programs. One servlet object handles any number of requests.

Each request is processed under separate thread so servlet object being used by many threads at a time.

To make servlet as thread safe:
#1 Implement SingleThreadModel interface, servlet process one request at a time. This will degrade performance. This approach is not recommended.
#2 Try to use local variables. When use shared/instance variable make sure those are thread safe.
