If a servlet implements this interface, you are guaranteed that no two threads will execute concurrently in the servlet's service method. The servlet container can make this guarantee by synchronizing access to a single instance of the servlet, or by maintaining a pool of servlet instances and dispatching each new request to a free singlethreadmodel java. Note that SingleThreadModel does not solve all thread safety issues.

For example, singlethreadmodel java, session attributes and static variables can still be accessed by multiple requests on multiple threads at the same time, even when SingleThreadModel servlets are used, singlethreadmodel java. It is recommended that a developer take other means to resolve those issues instead of implementing this interface, singlethreadmodel java, such as avoiding the usage of an instance variable or synchronizing the block of the code accessing those resources.
