Hi, this is my rants regarding computer sciences and socials. Currently my profession is a software developer, I love creating things that purposeful using computer , and to boldly go where no man has gone before. Delights? I am ..mostly caffeinated ;)Thursday, December 30, 2004
I have programmed some EJBs and wanted to test it out for some conditions and values,I need to do it fast, by scripting my logic and generate values from the EJB withoutmany codings.
My problems and expectations solved as I chose jython as the Java's implementation of Python. So I started by downloading the jython-21.class from http://www.jython.org/ and run it's setup. Because my EJB container is OC4J from Oracle, I asked some suggestions from my programming colleague John Rambo
then I create jndi.properties and META-INF directory in my jython directory script,
#contents of jndi.properties
java.naming.factory.initial=com.evermind.server.ApplicationClientInitialContextFactory
java.naming.provider.url=ormi://localhost/[your-ejb-app]
java.naming.security.principal=admin
java.naming.security.credentials=[yourpass]
<?xml version="1.0"?>
<!DOCTYPE application-client PUBLIC "-//Sun Microsystems,Inc.//DTD J2EE Application Client 1.2//EN" "http://java.sun.com/j2ee/dtds/application-client_1_2.dtd">
<application-client>
<display-name>Foo</display-name>
<ejb-ref>
<ejb-ref-name>com.foo.ejb.FooHome</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>com.foo.ejb.FooHome</home>
<remote>com.foo.ejb.Foo</remote>
</ejb-ref>
</application-client>
After I defined those files, I created a jython script "ejbtest.jy"
from java.util import Hashtable
from javax.naming import *
from javax.rmi import *
from com.acc.treasury.fundraising.drawdown.ejb import *
class FooEjb:
def __init__(self):
print "Initializing Context.."
self.context=InitialContext()
print "Getting EJB: com.acc.foo.ejb.FooHome.."
self.ejb= self.context.lookup("com.acc.foo.ejb.FooHome").create()
def print(self):
print self.ejb
FooObject=FooEjb()
FooObject.print()
It's that simple..yea! I had tested it in OC4j but for JBoss, WebLogic or WebSphere might seemed not much different .

In front of my PS2 console, I am indeed a gaming addict, talking about game and it's creation, I found interesting links about game development in PS2 and Xbox using Python as the scripting language.
In my job, I have used Python as main programming language applied to an ERP for a small-medium business, and content management system. But python as a scripting language for game development.? well I think you can check these links for sure. Just for an addition, Disney and EVE-Online use Python in almost every aspect of their MMORPG.
Python for Massively Multiplayer Virtual Worlds
PyGame
Developing game logic in Python
Python for Playstation
This is really a good news since many programmers think that a 3D game needs to be programmed in C or C++. for 3D engines you can check these links so you can start yourgame development faster. There are also some commercial engines and interesting free game engine like Reality Factory (this engine needs Delphi/Object Pascal to start and really helps as a good start.)
Reality Factory (Delphi required)
