How to connect Tomcat 6 with JTOM 2.0.10 and MySql 5.1

2008-12-19T01:08:00.009-06:00

I have tried to use Tomcat 6 with JTOM 2.0.10 and MySql 5.1 , but I it was unsuccesful, so then I tried to use another Transaction Manager, Atomikos, I find the docs and examples, but the example uses a Derby Database.

So I post how I've connected the MySql database using Atomikos and Tomcat 6:

Please follow the intructions that are posted here http://www.atomikos.com/Documentation/Tomcat6Integration33.

For the Web app please use the followin configuration in your WebApp Context File

Change the XA connection Properties according to your environment!!!

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/dbtest" docBase="dbtest.war" 
reloadable="true" crossContext="true">      
<!-- Resource configuration for JDBC datasource-->  
<Resource
name="jdbc/myDB"
auth="Container"
type="com.atomikos.jdbc.AtomikosDataSourceBean"
factory="com.atomikos.tomcat.BeanFactory"
uniqueResourceName="jdbc/myDB"   
xaDataSourceClassName="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource"
xaProperties.databaseName="test"
xaProperties.serverName="localhost"
xaProperties.port="3306"
xaProperties.user="USER"
xaProperties.password="PASSWORD"
xaProperties.url="jdbc:mysql://localhost:3306/test"   
/>
</Context>

See you!

Mono Pet Shop (C#, ASP.NET, MySQL)

2005-11-11T17:17:00.000-06:00

Last week I need to find a more robust example to develop enterprise applications using the Mono Framework... I couldn't find anything that satisfy my needs. So then I decide to port the .NET PetShop 3.0 Application which is a reference implementation of a distributed application.

The main goals were:

Port it using Mono 1.1.9.3
Update the DAAB 2.0 to DAAB 3.1
Use MySQL 4.1 instead of (SQL Server or Oracle)
Share the example with the community.

If you want to learn more about it stay in touch ... I will release the source and binary code very soon.

Help for the South of Mexico

2005-10-09T18:30:00.000-05:00

The tragedy and the poverty are the most hurting things that people can suffer, and right now the states located in the south of my country were affected (Chiapas, Oaxaca, Veracruz, Puebla, Hidalgo and Guerrero) by "Stan" hurricane.

We can help to those people in some way, we can donate food like sugar, oil, milk, chocolates and candies, beans, corn, rice, lentils, coffee, salt, cookies, soups, cereals, floor, tuna, sardines and bottled water.

Also bedspreads, blankets and articles of cleaning, as well as utensils of kitchen like pots, frying pans, can openers and bottle openers will be received, in addition to re-usable and disposable glasses and plates. Also, medicines will be accepted, such as: antibiotics, anti-flu, nutritional vitamins, complements, disinfectants, sticky tape, bandage and gauzes

You can send this help to any of the IPN schools and you can more information in the Social Service Office of the IPN, in the following telephone number 57-29-60-00, extensions: 51674, 51632, 51618 and 51671.

The LOGO Language, memories that come to me

2005-09-26T21:34:00.000-05:00

The last post that I wrote was about a Haskell Interpreter, I don't know how but now... I'm remembering about my first programming steps , they where using a Sigma Commodore 16 ( http://www.old-computers.com/museum/computer.asp?c=97) , come on I'm not an old person :P I was a kid in those days... I was 6-7 years old, that computer had a built-in BASIC interpreter, ohh my good,"for each line type a number and after type a command..." well it was good for me when I was a newbie programmer.

Many years after in the Elementary School I had a subject (Computing :P) and there I began to learn Structural Programming... with LOGO (http://el.media.mit.edu/logo-foundation/logo/index.html) a nice Turtle pointer that "walk" and "draw" lines, circles and other basic graphics functions. And then well my "new year" :P purpose is to make a new interpreter but using Mono, C#, and GTK#. It will be a interesting project... only with a educational goal.

I have started to search some projects about the LOGO and I've found

http://xlogo.free.fr/index-eshtml
http://klogoturtle.sourceforge.net/
http://lcs.www.media.mit.edu/groups/el/projects/circles/turtles.html
http://el.media.mit.edu/logo-foundation/logo/index.html
http://http.cs.berkeley.edu/%7Ebh/

Maybe they can provide the experience about programing a LOGO interpreter again the main source of information is the Linux Community Mailing List linuxipn@googlegroups.com.

Functional Programming With A Haskell Interpreter: Hugs 98 For The .NET Platform

2005-09-25T17:15:00.000-05:00

Some weeks ago I attended two classes of Elias Samra a Linux IPN Community Distinguished Member, and he spoke about the Functional Programing with the Haskell Language which has another point of view about giving solutions to specifics problems.

Since then I realized how can I apply the Functional Programming with Haskell to the near future projects of my consulting services firm, so then I started to do a little research about it.

As you know I'm a fan about the .NET Platform so then I decided to try some Haskell interpreter for this technology so I googled and found the Hugs98 for .NET ( http://galois.com/~sof/hugs98.net ), I installed it and run it, it gave me a nice command console... something like this:

Hugs98 - http://haskell.org/hugs - March 2003
Haskell 98 mode: Restart with command line option -98 to enable extensions
Hugs session for:
Type :? for help
Prelude>

And I started to program with the samples that it had, I was amazed that it can use the classes that reside in the namespace System.Windows.Forms, for example :

module Forms where

{-
This example uses DotNet actions to access .NET
rather than the FFI, as it was written before
FFI support was added to hugs98.net. Feel free
to upgrade it! :)
-}

import Dotnet

type Control a = Object a
type Config a = Control a -> IO ()

build :: IO ()
build = do
frm <- mkCtrl "System.Windows.Forms.Form" [option setSize (200, 200)] btn <- mkCtrl "System.Windows.Forms.Button" [option setText "Click Me", option setSize (50,50), option setLocation (75,75)] frm `addCtrl` btn event btn "Click" (\_ _ -> msgBox "Hello!" "Congratulations, you're running Haskell code!")
invokeStatic "System.Windows.Forms.Application" "Run" frm

option :: (Control a -> b -> IO()) -> b -> Config a
option f val = \ob -> f ob val

mkCtrl :: String -> [Config a] -> IO (Control a)
mkCtrl ctrlType options = do
ctrl <- newObj ctrlType () sequence_ (map (\x-> x ctrl) options)
return ctrl

event :: Control a -> String -> (Object a -> Object b -> IO ()) -> IO()
event ctrl name func = do
delegate <- newDelegator func () <- ctrl # invoke ("add_" ++ name) delegate return () setSize :: Control a -> (Int, Int) -> IO ()
setSize ctrl (width, height) = do
bWidth <- boxValue width bHeight <- boxValue height () <- ctrl # invoke "set_Width" bWidth () <- ctrl # invoke "set_Height" bHeight return () setText :: Control a -> String -> IO ()
setText ctrl text = do
() <- ctrl # invoke "set_Text" text return () setLocation :: Control a -> (Int, Int) -> IO ()
setLocation ctrl (x,y) = do
bX <- boxValue x bY <- boxValue y () <- ctrl # invoke "set_Left" bX () <- ctrl # invoke "set_Top" bY return () add :: Object a -> Object a -> IO ()
add collection thing = do
() <- collection # invoke "Add" thing return () addCtrl :: Control a -> Control a -> IO ()
addCtrl parent child = do
ctrls <- getControls parent () <- add ctrls child return () getControls :: Control a -> IO (Object a)
getControls frm = do
ctrls <- frm # invoke "get_Controls" ()
return ctrls

Again I can prove the interoperability whit the .NET Platform and the Hugs98 interpreter that target it, I will do more complex programs that implements Functional Programming and I will post my results.

Again I invite you to try the Functional Programming and take a look at: http://galois.com/~sof/hugs98.net/

PHP Compiler For .NET Framework

2005-09-22T22:19:00.000-05:00

When I was a young boy I used to program web pages with PHP, an easy to learn script language programming, but after many headaches that it gave me... I decided to try others for web programming (Java) , in that days I promised I will never try to use PHP again (come on this scripting programming language doesn't promote the code reusability neither the OO Programming and Design, it doesnt have a debugger, its non-existing typing enforment allow many runtime errors... ).

But ... something new was making it appearance in the scene: The .Net Framework and of course the Mono Project (www.mono-project.com) that implements many features and improvements of the Java Virtual Machine and Runtime Classes.

I like this framework because it allows to reuse the knowledge about the programming language of our choice, the .net framework is targeted by many languages, and you can mix the assemblies (binary files) .... well many many advantages. And I like the Mono Project because it targets 7 hardware platforms, it's Open Source and led by a mexican Miguel De Icaza.

And today I found and tried the Phalanger which is a PHP Language Compiler for .NET Framework ( http://www.php-compiler.net ). I think it's an interesting option for all that PHP lovers who want to improve their web applications.

Finally you can run your PHP in a managed environment, and use all the benefits of the .net framework.

The only "but" that I can express, PHPlanger is not a Full Open Source Project, and it doesnt work on Mono because it has PInvoke dependencies. :( To bad but it's a good starting point to make a full free PHP compiler)

Download it and try it by your self.

Mono Live: Mono al Rojo Vivo

2005-09-06T16:52:00.000-05:00

La plataforma Mono permite desarrrollar y ejecutar aplicaciones basadas en estandares ECMA e ISO; en otras palabras estos permiten ejecutar programas de los frameworks Java y .NET. Ahora bien aprovechando la sencillez de colocar en un CD e iniciar con el la computadora y ejecute un sistema Linux con la plataforma Mono integrada sin tener que instalar, reparticionar y un etcetera de pretextos; se ha sacado a la luz Mono Live que contiene y permite: - Ejecutar un sistema Linux Ubuntu - Desarrollar, compilar y ejecutar software con: Monodevelop - Escuchar musica con Muine - Tomar notas con Tomboy - Administrar Fotografias con F-Spot - Buscar musica, fotografias, conversaciones y documentso con Beagle - Utilizar y evaluar aplicaciones web como ASP.NET Forums, IBuySpy y mojoPortal - Instaladores del Framework Mono para MS Windows
Se puede descargar la imagen ISO de del BitTorrent o bien mediante HTTP

Espero puedan descargarlo y evaluar la plataforma de desarrollo Mono.
