title: Accessing a servlet instance
body: <p>while i can't really think of a practical use-case for such a scenario, but i purely intend this to be a curiosity driven question.  </p>
  
  <p>i understand the servlet container holds onto all the instances created of the servlets, and delegates request threads to these instances. it also makes sense to keep these instances managed, to avoid unwarranted calls to alter the lifecycle of servlet instances outside the purview of the container.  </p>
  
  <p>but is there really no way to access the servlet instances?</p>
