web-jsptaglibrary_1_1.dtd
I could not find this file on my computer. I did a cut and paste from the
web of this file. I updated my struts-bean.tld file to use it locally and
I get an error "Severity Description Resource In Folder Location
Creation Time Id
1 The file cannot be validated as the XML Schema
"c:\TEMP\web-jsptaglibrary_1_1.dtd (The system cannot find the file
specified)" that is specified as describing the syntax of the file cannot
be located. struts-html.tld SplitTransaction/WebContent/WEB-INF line 2
June 14, 2006 9:10:13 "
It is referred to in the struts-bean.tld as well as struts-html.tld and it
really exists there... What am I doing wrong?
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1
//EN" "c:\temp\web-jsptaglibrary_1_1.dtd">
I downloaded it and renamed it(the download indicated it was an html file).

If connection is timing out, then I would suggest this as a firewall issue
and you are not allowed to get to the HTTP address. As Rick suggested, just
remove the DOCTYPE tag all together unless you need to validate the XML
file.

is there a reason you can't just specify the http address ??

Or just take it out completely unless you need it validated.

Re: Multiple instances of servlets
Posted by Mark Thomas <ma...@apache.org>.
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).

As I mentioned earlier it is mydomain2 that get four instances of the
"BookingManager" servlet.
Comments?

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.

Multiple instances of servlets
Posted by Magnus Larsgården <ma...@kbab.net>.
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
