Multiple instances of servlets
Hi all,
Is Tomcat supposed to create multiple instances of my servlet at startup? Or
is it a bug?
Background:
========
I have two different domains connected to my Tomcat server (version 5.5.17):
http://mydomain1.host.com and
http://mydomain2.host.com
"mydomain1" is directed to /home/web/tomcat/webapps/ROOT/
and "mydomain2" is directed to /home/web/tomcat/webapps/mydomain2/
Both domains use a copy of the same servlet except that they belong to
different packages. Ex:
The .java files under mydomain1 belong to package
"com.mydomain1.bookingManager" and are located under
/home/web/tomcat/webapps/ROOT/WEB-INF/classes/com/mydomain1/bookingManager/
The .java files under mydomain2 belong to package
"com.mydomain2.bookingManager" and are located under
/home/web/tomcat/webapps/mydomain2/WEB-INF/classes/com/mydomain2/bookingManager/
Problem:
======
When Tomcat starts it creates only ONE instance of the "mydomain1" -servlet,
and FOUR instances of the "mydomain2" servlet.
I would really like to only have ONE instance of each servlet. How can I
achieve this?
I have searched Google for answers but only found contradicting statements.
Some say that Tomcat creates one, and only one instance of each servlet.
Other say the opposite.
All help is appreciated!
Thanks in advance
BR/Magnus

When starting a new thread (ie sending a message to the list about a
new topic) please do not reply to an existing message and change the
subject line. To many of the list archiving services and mail clients
used by list subscribers this makes your new message appear as part
of the old thread. This makes it harder for other users to find
relevant information when searching the lists.
This is known as thread hijacking and is behaviour that is frowned
upon on this list. Frequent offenders will be removed from the list.
It should also be noted that many list subscribers automatically
ignore any messages that hijack another thread.
The correct procedure is to create a new message with a new subject.
This will start a new thread.

Hi Len,
The SingleThreadModel Interface is _not_ used in the servlet.
Maybe I should write a bugreport?
Thanks for your help!

I don't see anything there that would cause the servlet in mydomain2
to be loaded 4 times. The only thing I can think of is that the
servlet might be running in single-thread mode (by implementing the
SingleThreadModel interface).

Subject: Re: Multiple instances of servlets
How many web.xml files do you have, and how many <servlet>
declarations are there in those files? Each one of those is a
different servlet (even if some of them happen to be implemented by
similar Java classes). Normally, Tomcat will create one instance of
each of those servlets (or one per JVM in a distributed application).
Things are different if you use the single-thread model, but that's
not recommended.
See the servlet spec for the official details.

> Problem:

> I have searched Google for answers but only found contradicting statements.
> Some say that Tomcat creates one, and only one instance of each servlet.
> Other say the opposite.
