While reading through “220.127.116.11 Multithreading Issues
” in “Java Servlet Specification V3.0
” below statement is confusing me
For servlets not implementing the SingleThreadModel interface, if the service method (or methods such as doGet or doPost which are dispatched to the service method of the HttpServlet abstract class) has been defined with the synchronized keyword, the servlet container cannot use the instance pool approach, but must serialize requests through it.
What does it mean by “Servlet Instance Pool”. As we know, there can be only one Servlet instance per declaration per JVM (in an non-distributed environment). Was “Thread Pool” misspelled as “Instance Pool” here? I believe Thread Pool also does not make any sense here. Tried search the web, but couldn’t get the relevant answers.
