Hello,
Do you know of any Servlet add-ons for apache that actually handle
servlets / servlet engines in this way? We'd like to offer more than
just a guestbook servlet, but we can't afford to invest a lot of people
resources to police servlet performance, memory usage, etc.
What ISP's need is something like SUEXEC for apache, that runs the
servlet with the user's permissions, and that also controls the startup
and shutdown of servlet engines. Will servlets function under SUEXEC?
Then we could set ulimits for user groups, so that users can't run away
with memory, but how do we set up the servlet zones to actually run the
servlets in separate engines?
I am new to servlets, so please forgive me if this is simple.
