Re: How does a servlet request work. Not a newbie question ;)

[Bill Barker]

I'm answering the question that you asked, but my answer is less useful than Yoav's :).

With a small number of exceptions (such as POSTs to j_security_check), 
Tomcat-standalone reads the headers, and leaves the body until your servlet tells it 
what to do with it.  The case of Tomcat-Jk is a bit more complicated, so ask again if 
you really want to know :).

  Hi all

   

  I want to insert some form of scheduling into our application and I was wondering 
how Tomcat passes the request to the actual servlet I write. Does Tomcat just read the 
headers to create the request object and leave the body of the message in an 
inputstream for the servlet to read or is all the data in the request read by Tomcat 
before passing it to servlet?

   

  Some of my traffic is more important that other based on headers in the request. I 
want to prioritise the handling of requests under load conditions.

   

  Any input on this is welcome.

  Thanks

[Shapira, Yoav]

Howdy,
I see three options that fall within the realm of not a huge amount of
work:

- Dig into tomcat source code, extend Coyote in some custom way to
recognize your headers, recognize what you call "load" (which is much
harder to do than recognizing headers), and filter requests
appropriately.

- Create a simple Filter (ServletFilter) that looks for your request
headers, again recognizes "load", and filters requests appropriately
(this filter would be mapped to url-pattern /*).  This is far less
efficient than the Coyote solution, because you will reject requests
further along the processing pipeline that you need to, but this
approach is portable.

- Attack the problem with clustering: install more tomcat instances and
a load balancer, ideally one that can assign weights to your workers and
direct requests to workers according to headers.  (The balancer webapp
that ships with tomcat 5 has a request header rule that will let you
redirect requests based upon header values -- you'd have to add the
"load" recognition capability).

RE: How does a servlet request work. Not a newbie question ;)

Hi Nix

I need to read the headers to see if the request can be moved up in
priority. If no I will put that particular servlet into a wait state to be
woken up by some scheduler I create in the servlet engine. 

Ideally, all requests will be processed but some will be done before others.


It is not a login or cookie application. We are not using browsers to access
the application so the headers are customizable and we know the type of
message arriving. It's just we want some types of messages to be done. Under
load we can reject certain messages that are not high priority if an
internal processor cannot be assigned with a specified time frame.

Thanks
Donie

I'm not aware of any priority scheduling in Tomcat's worker threads. There
is no
public API for that, anyway.

If I understand correctly, you'd like people to login to a part of your app
and
then they will be issued a Cookie, which would be the token for boosting
priority of such requests. Possibly in a Filter.

Unless you wish to employ your own thread pools, internal or real, I think
this
is a no-go.

As a quick solution, you'd be better off using IP layer stuff, like IP QoS
(Quality of Service), Linux policy routing, etc.

Re: Reposting [INIMSS] How can I load a custom jar file for a particular web application. [a newbie question]

[David Smith]

Well then the class structure would be placed in WEB-INF/classes where the 
classloader structure would find all your .class files.  Then you would 
reference your classes on the import line as ClassA.ClassA1 for example.  

If you write them yourself, make sure each source .java file has a package 
line at the top defining the package they are associated with.  Then compile 
them.

It would be extremely helpful if we knew what version of Tomcat is running.  
If we're talking TC 4, then place it in WEB-INF/lib of your webapp and then 
restart the app.  I believe that holds true for 3.3 as well (I'm more 
familiar with TC 4).  For versions before 3.3, the classloader system wasn't 
implemented yet and you'll have to put it in the classpath somewhere.

Subject: Reposting [INIMSS] How can I load a custom jar file for a
particular web application. [a newbie question]


Hi

Please help me ASAP.

I am having a third party jar file that is to be loaded from jsp pages to 
attain some task. The particular jar file is to be used only buy one web 
application. Where should I place the files and what all should I modify to 
make it work?

I am using tomcat 3.3 and  apache-1.3.19-5 on RedHat Linux 7.1.

Thanks
Dino CK

Re: A newbie question about Tomcat and Webalizer

[Craig R. McClanahan]

When you run Tomcat 4.0 stand alone, it generates webserver-style access
logs by default, in the "logs" directory.  The default filenames will be
of the form "localhost_access_log.-MM-DD.txt", and will switch over
automatically each midnight without having to be restarted.

As to 4.0, I think that the answer is, "Probably." You would have to edit
the file server.xml (the primary Tomcat config file) to add a Logger
component (if not already in your server.xml file) for each container for
which you wanted logging. Tomcat 4.0 includes an optional Valve
implementation (which would involve more changes server.xml) that can
create access logs in the same standard format created by web servers, or
in any custom format desired. In order to have still more information
written to the log, you could try adjusting the value of the attribute
"debug" in the relevant component tag. The higher the debug level, the more
information would be written to the log. The default debugging level is
zero, and it can be set as high as nine.

The documentation for 4.0 has a great deal on logging, and that's the
source of my knowledge of this topic.

A newbie question about Tomcat and Webalizer

[Marcel Schepers]

Hello,

At the moment I am running an tomcat in combination with Apache. However 
  there is no reason to use Apache, except that I use webalizer to 
generate web site stats. My question is: is it possible to configure 
Tomcat (3.2 and 4.0) in such a way that I can continue  to use webalizer?

Thank you,
Marcel

Hi :-)

*
   - if we don't set servlet-maping in WEB-INF/web.xml, now it means
 we will use the "Non-standard invoker, for backward compat" syntax
 to invoke MyServlet class, like the following:

http://[server]:[port]/[ContextName]/[invokerName]/[ServletName/servlet-declarationName]

   - and if we also don't change the "Non-standard invoker" in
conf/server.html,
  it means now we will use the "default one":  it is "/servlet/"

  so now the sytax should be:

http://[server]:[port]/[ContextName]/servlet/[ServletName/servlet-declarationName]

(it is not "/servlets/", it is "/servlet/")


*
   - if you Do change the "RequestInterceptor" from "/servlet/" to
 "/servlets/", your 1st syntax will be right .

   - if you define a servlet-declaration in WEB-INF/web.xml, you also
 can use the following syntax:

http://[server]:[port]/[ContextName]/[invokerName]/[servlet-declarationName]

   - if you define a servlet-mapping in WEB-INF/web.xml and you also
want to use it now,
  now it means you will Not use invokerName, you will directly use
the following syntax:
http://[server]:[port]/[ContextName]/[servlet-mappingName]

(*  ContextName is defined in conf/server.xml)


* the following is from conf/server.xml of jakarta-tomcat-3.2.1, but I
don't
   find it in TC4.0-b5,  I guess it means:
- TC4.0-b5  still use "/servlet/" as default "Non-standard invoker"
- but Only when I try to change it, then I  have to write them in
conf/server.xml,
   otherwise I don't need to write.  is it right?  thanks!
