OT Ann: North East Conference on MVC Frameworks and Struts in 3 weeks:

[Vic Cekvenich]

Most people already know what MVC is, once you know what it is, here is 
the next step. Presenting will be the popular frameworks and components 
in use by 8 speakers:

-Ted Husted – Author – Struts Chains/2.0 – the dominant framework in 
use, from Ziff Davis, to Apple Store to most large commercial sites.
Husted.com

-Rod Johnson – Author – EJB/Spring
springFrameWork.com
-Christophe Coenraets – Flex-MacroMedia  - “back to rich UI w/SOA” 
(Great blog entry on Struts + Flex)
markMe.com/cc

-Howard Lewis Ship – Author – HiveMind (SOA, IOC, AOP) –  commonly 
referred to as “the next big thing”
javaTapestry.blogspot.com

-Clinton Begin – DAO/iBatis/SQLMaps – the best DAO layer
imo, used by Spring, jPetStore, basicPortal, etc.
-Matt Raible – Author – displayTag/strutsMenu – (displayTag is my 
favorite J2EE component)
Raibledesigns.com

-Jason Carreira – WebWork 2
freeroller.net/page/jCarreira
- Vic Cekvenich – Author – basicPortal (J2EZ – easy and simple to 
customize application for membership, portal, cms, community, store, 
etc. using bestPractices for large, profitable commercial sites. )

+ more
You will get a CD mailed to you once you register.
April 3rd from 8AM to 7PM in NYC at nyhotel.com, next to MSG. Advertised 
in JDJ, NY Times, etc. My guess is that you won’t find half as many good

C# is much faster than Java. My concern is, can Java/JSP still be

Re: how to suppor 30000 concurrent users

[Vic Cekvenich]

If you use Resin/J:Rockit/NewISys 2100, you can do at least 4,000 
cocurent users w/ sub second response time. (test your app w/ free 
DiselTest - part of Jasic and linked on basicPortal.com, other links 
there to)
NewIsys is a 1U.
A 19" rack can hold 40. You need 3-4 racks.
He.net charges $400 per month per rack, so $1200-$1400 for 3-4 full 
racks to co/lo. (I might cost out blade performance to lower rack cost).
Tou migh want to use pgSQL.

Open source is great at large sites that are run for profit. (I wonder 
what MS SQL/Share point costs for 4 racks?)

Good luck.

Dont take a chance that training is too intro, or & . We give you money 
back guarantee, take the 3 classes, you must do the labs, and after you 
watch all the sessions, ask for money back if you do not think it was 
valuable, no questions asked.

Shortly after you register, you will receive the training materials, a 
book and the labs.

Yes, this is advanced Struts labs, only for people that already know 
Struts, learn by doing.
We will write an application from scratch in Struts with DB access, 
updates, master detail processing, validation, navigation, tiles, JSTL, 
testing, reporting, mail, etc. We will cover good practices and bad. 
Full agenda to follow on the mail list (sign up for mail list on the 
main page of baseBeans.com).

Students are always able to retake future training for FREE (even live

new sample "best practice" Struts data driven web app for Tomcat5/Resin 3

[Vic Cekvenich]

I released a new basicPortal implementation called "bP v0.8k" available 
for download on basicPortal.sf.net.

- The new version is same simple "bean has a dao helper design", but it 
uses ibatis.com db layer. (the "older" design used RowSet) Ibatis db 
layer is very nice.

- It now works fine and is tested with MYSQL. (and pgSQL)

- It is build for JSP 2.0 containers, like a late build of resin 3 and 
tomcat 5, tested to work with both (but could be converted to JSP 1.2 
with addition of the c tag)

- It now has a list of maps backed beans for more flexibility. (old 
design was rows of columns), aka list backed bean.

- It uses display tag (struts menu, JSP2, JSTL, tiles, etc.)

- Like before, the base action dispatches, DAO is a interface (so you do 
not have to use iBatis db layer) and beans knows how to CRUD, via very 
nice OO.

Of course... still more to do

JK and Apache

This list is becoming a JK/Apace list. :-(

Not starting to try a flame, but a word to the wise:
IMO, using Apache or JK in most circumstances is a bad practice. This 
goes back when sales people would say you need Apache, and Tomcat and 
EJB server. No need for that. Fact is Tomcat can do it all, display HTML 
and do JavaBean persistance.

http://www.caucho.com/articles/benchmark.xtp
See last line says JSP and static performance is similar, only in JSP 
you can CMS to DB.
Plus a lot less admin time.

I take it you disagree. You can load balance Tomcat just fine.

IMO: It's a good practice to try to avoid using Apache. Mostly newbies 
think that this is required. I am just saying, this is not required or 
possibly good.

It makes operations and development easier not to have Apache, and my 
clients have removed it to great sucess. Take it into consideration a

Please don't troll the list.  There are all sorts of reasons besides "need
CGI" to use Apache.  I can think of one right now (load balancing) that
would pretty much make using Apache mandatory in many installations.

In the past, (Hardware sales) people would say you need a html server

Now Tomcat can server HTML pages very fast and can do SSL, etc.

There is no reason to maintain and configure in operations

Recomendation: It is *a good practice to deprecate Apache!, and use

The speed is just fine.

There are only a few exceptions, such as you need CGI, but you can save

Re: Database load balancing?

Try caching first; with Poolman.sf.net or

Replication could slow you down.

Ralph Einfeldt wrote:
It depends on your requirements.

For read only load balancing to achieve more performance
you might also consider to use replication:
http://gborg.postgresql.org/project/pgreplication/projdisplay.php

This way you could for exapmle setup 4 instances of
tomcat and 2 instances of postgreSQL where one db instance
is shared by two tomcats.
This is no true loadbalancing, but might give you 
enough power through the use of serveral db instances.

The main drawbacks against true load balancing are:
- no simple fail over (you would have to implement on your own)
- no load based switching between databases. (The 
  connectiones between the tomcat instances and
  the databases are rather static)

You migh also read the following article
http://conferences.oreillynet.com/presentations/os2002/johnson_darren.pdf
with pointers to other replication solution to postgreSQL.

Does anyone have a clue about load balancing read-only 
database requests to PostgreSQL?  I'm developing a 
data-intensive application that requires scalability, 
not just from Tomcat, but from Postgres as well. 
I will use hardware load balancing to Tomcat, but I cannot 
do the same to a database using persistent connections.

The only thing I've seen (after several days of searching) is
DBBalancer, an alpha release load balancer with no JDBC support.

Thanks a million Les,

This is very helpful.

Quick question: I didn't see a jar in th DBCP nightly build after I
downloaded it, how do you build this thing?

Thanks again,

Rick

Subject: [[EMAIL PROTECTED]] [Struts Tips] #2 - Use 
DispatchAction to organize related operations
Date: Mon, 25 Mar 2002 09:11:07 -0500
From: Ted Husted <[EMAIL PROTECTED]>
Reply-To: [EMAIL PROTECTED]

Newsgroups: MVC-Programmers
References: <[EMAIL PROTECTED]>

Any software application is defined by the things it can do for you. In
a Struts Web application, the things an application does is usually
defined by its action-mapping elements. An action-mapping is designed to
be the target of an HTML form, and is often used with hyperlinks as
well.

Each action-mapping can specify a Struts Action class as its handler. In
larger applications, developers can find themselves managing dozens or
even hundreds of Action classes.

In practice, many of these Action classes handle related operations,
often evidenced by their name. A package might include separate
RegCreate, RegSave, and RegDelete Actions, which just perform different
operations on the same RegBean object. Since all of these operations are
usually handled by the same JSP page, it would be handy to also have
them handled by the same Struts Action.

A very simple way to do this is to have the submit button modify a field
in the form which indicates which operation to perform.


function set(target) {
  document.forms[0].dispatch.value=target;
}



SAVE
SAVE AS NEW
DELETE

Then, in the Action you can setup different methods to handle the
different operations, and branch to one or the other depending on which
value is passed in the dispatch field.

String dispatch = myForm.getDispatch();

if ("create".equals(dispatch)) { ...

if ("save".equals(dispatch)) { ...

The Struts Dispatch Action is designed to do exactly the same thing, but
without messy branching logic. The base perform method will check a
dispatch field for you, and invoke the indicated method. The only catch
is that the dispatch methods must use the same signature as perform.
This is a very modest requirement, since in practice you usually end up
doing that anyway.

To convert an Action that was switching on a dispatch field to a
DispatchAction, you simply need to create methods like this

 public ActionForward create(ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
 throws IOException, ServletException { ...

 public ActionForward save(ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
 throws IOException, ServletException { ...

Cool. But do you have to use a property named dispatch? No, you don't.
The other step is to specify the name of of the "dispatch" property as
the "parameter" property of the action-mapping. So a mapping for our
example might look like this:

  // Which parameter to use

If you wanted to use the property "o" instead, as in o=create, you would
change the mapping to

  // Look for o=dispatchMethod

Again, very cool. But why use a JavaScript button in the first place?
Why not use several buttons named "dispatch" and use the values to
specify the operation.

You can, but the value of the button is also its label. This means if
the page designers want to label the button something different, they
have to coordinate with the Action programmer. Worse, localization
becomes virtualy impossible.

If you prefer not to use JavaScript buttons, you can use the
DispatchLookup Action instead. This works much like the DispatchAction,
but requires more setup. We'll explore the DispatchLookup Action in Tip
#3.

HTH, Ted.

[ANNOUNCE] Fast Track to MVC / JSP Framework Public Workshop

[Vic Cekvenich]

http://java.sun.com/j2ee/blueprints/introduction/summary/index.html


This is the first MVC and JSP public training class. The framework we 
will be learning is open standard Struts. For more on Struts and related 
technologies, click on:

http://jakarta.apache.org


You will master Struts in three days in Dallas ( 
http://www.wyndham.com/Anatole), starting Dec. 2nd. This class is for 
trainers who will teach this class in the future, but a limited number 
of students are also permitted.

Trainers will be able to establish themselves as leaders in the 
upcoming technology. Students will upgrade their skills and become more 
marketable as well as learn proper development techniques.

For more information, including a list of topics and details on 
registration, please click on:

http://www.basebean.com


What Will be Covered:

*  DB Connection /Warm-up with JDBC and RowSet
   
*  Test Framework and RDBMS, Install Struts
   
*  Retrieving Data from SQL to Struts

*  OO Based Development and Extension

*  Drill Down from Screen-to-Screen
   
*  Data Entry Crud, Update, Insert and Delete

*  Master Detail Processing

*  Security Based on DB Roles

*  Portal Tiles (build real portal applications w/ layout for
headers and footers)

*  Menu - Build a Struts Menu for Navigation

*  Deployment


You will  discover why flexibility is enhanced by using MVC/J2EE 
architecture in conjunction with a SQL database. This is the first and 
only public MVC/JSP class of its kind. We will learn to utilize applied 
technology toward solving business problems.


Tomcat is used for developing, then we deploy to OrionServer.com.
