Java EE 7 Is About To Coming?

2011-01-29T12:21:00.000+07:00

Java EE 7 AKA The Cloud some feature: multi-tenancy, application versioning, support for NRDBMS stores but also about modularity, trying to leverage what will be done at the JavaSE level. Of all the APIs up for a new version, JAX-RS and JPA seem to be the closest to being filed as JSRs.

It's been one year since Java EE 6 was released (December 2009) and it's now time to start talking about Java EE 7. In fact at JavaOne San Francisco in September, at Devoxx in November and at JavaOne Sao Paulo and Beijing in December, the technical keynotes have gradually introduced what Oracle would like to see addressed in this release.

My Footnotes About Adobe Flex (Indonesian language)

2011-01-25T23:22:00.001+07:00

*. Adobe Flex adalah RIA yang mirip dengan Ajax, JavaFX, Silverlight or XUL

*. Flex platform:

MXML utk design form
ActionScript 3.0 utk scripting
FlashPlayer 10.0 utk plugin webbrowser utk compile bytecode (.swf)
Server Side integration via Flex Data Services, GraniteDS or BlazeDS, giving the applications access to J2EE applications.
Also the flex application could be connected to other server technologies such as PHP, Coldfusion and ASP.NET.
Flex Builder, yaitu IDE berbasis Eclipse

*. Flex berintegrasi dengan server menggunakan salah satu dari:

Webservices
ColdFusion Flash Remoting Service.
Action Message Format (herein AMF) used in BlazeDS, GraniteDS and LiveCycle Data Services.
This is the way in which NCSIS applications will be developed.

*. Benefit Flex:

Rapid prototype
Multi Browser compatible
Aplikasi Flex adalah statefulness yang berarti tidak memerlukan request setiap saat ke server
Jalan diberbagai webserver dan bisa konek ke webservice
Menggunakan AMF lebih cepat webservice

*. Flex berkomunikasi melalui RPC dan protokol HttpServices, WebServices, RemoteObject

*. Proses membuat aplikasi Flex:

Buat form MXML
Buat ActionScript sesuai fungsinya
Compile the code, form MXML dan ActionScript akan menjadi file .swf yang bisa dijalankan di FlashPlayer
Deploy .swf file dengan mengembbed kedalam HTML

*. MXML adalah GUI

*. ActionScript adalah logic

*. ActionScript adalah asynchronous yang berarti method dijalankan oleh server tetapi tidak mengembalikan nilai

*. Cara link MXML dan ActionScript:

Embed ActionScript code didalam
Import eksternal file
Import ActionScript classes
Import ActionScript compiled components

*. Contoh cara manggil ActionScript ke dalam MXML:

-----------------Test.mxml

-----------------TestAS.as
public function sayHello():String
{
var response:String = "Say Hello World";
return response;
}

*. Dalam MXML Flex juga dikenal istilah DataBindings seperti PageDefinitionnya Oracle ADF:

{first.text}
{last.text}

*. Validasi di Flex bisa melalui:

ActionScript
DataBindings
Events

*. Cairngorm merupakan framework MVC yang digunakan sebagai event model utk memanggil dan menerima panggilan dari server

*. Cairngorm akan sangat membantu terutama apabila bekerja dengan lebih dari satu developer dan project dengan skala besar

*. Cairngorm komponen:

ValueObject utk pojo di level view (isi VO ini sama persis dengan pojo di level server)
Event akan mentrigger business logic yang di Command utk segera di proses
FrontController utk mapping antara Event dan Command
Command yaitu utk proses business logic
BusinessDelegate
ServiceLocator yaitu utk menentukan di view akan memanggil service apa yang berkaitan dengan form tsb
ModelLocator yaitu global data (di JDev seperti adapter)

*. [Bindable]
public class ModelLocator implements IModelLocator
Bindable disini artinya semua variabel yang di define didalam class tsb bisa dijadikan data binding

*. Urutan flow Cairngorm: View -> Event -> FrontController -> Command -> Delegate -> ServiceLocator -> Model -> View
Contoh penjelasannya dalam form login:

Form login mempunyai button login, button login tsb akan mentrigger event.
FrontController akan mencari Command apa yang sesuai utk Event tsb.
Command kemudian akan mendelegasikan tugas kepada ServiceLocator utk meng-execute business logic di sisi Server.
Hasil execute tersebut (entah select/insert/update/delete) akan mengembalikan Model yang kemudian di tampung lagi ke View

Welcome to Adobe Flex and goodbye Oracle

After 2 years working on Oracle stack technology at Bizol Cipta Solusi (ADF, Toplink, JDev, OC4J, Oracle Database), finally i'm leaving.

I have been waiting opportunity to move almost a year.

Now i'm move on to Plasmedia. Hired for 8 month until August 2011.

They using:
Adobe Flex as client technology
Java as server technology
Hibernate as ORM
Spring as dependency injection
BlazeDS as connector between client and server
JBoss as webserver
SVN as source code management
Alfresco as portal document management
Jira as bug tracker
MyEclipse with FlashBuilder plugin as IDE
Oracle as database

Some of them are new for me such as Adobe Flex and BlazeDS, but i will keep learning :)

So many earthquake happened in Indonesia.

How can we prevent it ? Of course we can't its a force majore, but wait there is add-on for Firefox named eQuake Alert.

eQuake Alert is a handy add-on, which alerts you with the basic information (date, location, and magnitude) of each earthquake. By default your browser will shake proportional to the earthquake magnitude. You can configure the alert methods and even you can limit the alerts by the earth quake magnitude. The recent quakes menu provides a link to the detailed information of quake @ the USGS (US Geological Survey) website.

ADF How To Clear or Reset Search Form in Jdev10g

2009-08-21T09:27:00.006+07:00

Google Blogger does not allow me to upload attachment so wait for 4 images loaded.

OTN Forum

The problem :
Let say my application based on HR schema. I've search form for employees and departments.
For employee we can search by first name, last name, email and so on.
For departments we can search by department name and manager.

So i enter employee search form and search employee first name Steven. I got 2 records, thats fine.
I leave to another form and now the riddiculous thing are when you come back to employee search form again,
you'll see your previous first name parameter Steven and your previous result which is 2 records.

Thats mean to me Oracle does not clear / reset input value in the form.

I have no idea why Oracle leave the mess like this. Is this a bug or not i don't know.

The solution :
Thanks to Olaf Heimburger article to give me inspiration.
In his blog, Olaf said he got hint from Frank Nimphius. So i gave credit to him too.

Here is original Olaf piece of code :

Its works perfect. But hey i have a lot of search form am i suppose to put that code on my every page ?
Of course not.

Step 1 :
Here is the modified code. I put this into JSFUtils.java :

Step 2 :
And now how can all the search form calling those method ? The key is an interceptor class before and after loading the page

Thanks to OTN forum. So i create class to intercept like this :

Step 3 :
Now the implementation is simple, just add this simple code in each PageDefinition header like this :

Above is the general, if you want to customize you can override onPageLoad and onPageRender method in backing bean.
Just extend the class like this
public class EmployeeSearchForm extends CustomPagePhaseListener.
Remember your PageDefinition is now no longer point to CustomPagePhaseListnener, but point to your backing bean class
which mean EmployeeSearchForm.

My environment :
*. XP SP2
*. JDev 10.1.3.3
*. Oracle Database 11g

Toplink Jdev10g How To Delete Child Record

2009-08-20T17:18:00.005+07:00

The problem :
Recently i've found problem when trying to delete the record with child record programmaticly using Toplink in Jdev10g.

For example imagine i'm about to delete IT Department in HR schema.

Here is my piece of code in SessionBean to do that :

uow.deleteObject(itDept);

And my embedded OC4J thrown me
Exception TOPLINK-4002 (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061214)): oracle.toplink.exceptions.DatabaseException
Internal Exception: java.sql.BatchUpdateException: error occurred during batching: ORA-02292: integrity constraint (FK_CHILD_PARENT) violated - child record found

The solution :
There is nothing wrong with above code and maybe nothing wrong with your code too LOL. What i'm doing a little modification in TopLink Map Descriptor (tlMap1.mwp).
Tick Private Owned in each collection of Departments class (see screen shot).

My Environment :
*. XP SP2
*. JDev 10.1.3.3
*. Oracle Database 11g

EMEA stand for Europe Middle East and Africa.
I live in Indonesia so i choose APAC version.

Preparation :

1. In your PC :
*. Create restore point through Start -> All Programs -> Accessories -> System Tools -> System Restore. Name it 'Before flashing' click create.
*. Remove Nokia PC Suite, Nokia Software Updater, Nokia Care Suite, Nokia Modem Drivers, Nokia Connectivity Drivers through Control Panel -> Add/Remove Programs, but DO NOT REMOVE PC Connectivity Solution and Windows - Nokia Modem.

*. Restart your PC.
*. Do not connect your phone before installing Phoenix software.
*. Disable all antivirus, firewall, antispyware, antimalware etc.
*. Disable screen saver.
*. Check C:\Program files\Nokia\Phoenix\Products\ If you have those folder in there delete all.

2. In your mobile phone :
*. Backup all your mobile phone content since all your data will be lost after flashing.
*. If you protect your memory card with password, then remove it.
*. Remove your memory card from your mobile phone.
*. Go to Tools -> Settings -> Security -> Phone and SIM.
Set Pin code request to Off.
Set Autolock period to None.
Set Lock code to default password which is 12345.
Set Lock if SIM changed to No.
*. Uninstall your mobile antivirus.
*. Charge your phone battery to at least 70% and keep charging. Although flashing takes only 7-10 minutes.

Begin Flashing :

1. Installing Phoenix Service Software 2008 or later :
*. First Extract the archive you have downloaded which contains Phoenix Service Software 2008 or later
*. Install the software. Be patient, it may take some minutes to install all the components.
*. Don’t run Phoenix software now.
*. Connect your Nokia handset to your pc with USB cable in PC Suite mode.
*. windows will start installing the connectivity drivers as soon as you connect the phone. Let it install completely.
If this process failed then you must be remove PC Connectivity Solution. But don't worry we created restore point earlier remember. Restore your system and start remove Nokia component again but do not remove PC Connectivity Solution.

2. Installing Firmware Files From The Offline Package You Downloaded :
*. If your firmware file is in .rar format, first extract it using WinRar on desktop.
*. On desktop you will find .exe file of your firmware file.
*. Install the exe file. Do not change its path. It will install it to default location of C:\Program files\Nokia\Phoenix\Products\
*. If you have downloaded a firmware File which Doesn't have an autosetup, then just copy your Extracted folder Manually in the directory C:\Program files\Nokia\Phoenix\Products\
*. Be sure you install updated firmware. You cannot downgrade your phone’s firmware in BB5 phones which includes all new Nokia phones including N-Series.
*. Phoenix allows downgrading but your phone doesn’t allow it as your phone has some special security built into it. So no use of trying it. You’ll get an error message.

3. Flashing Procedure (Updating to latest firmware version) :
*. Open Phoenix Service Software.

*. Connect your phone in PC Suite Mode.
*. In Phoenix, click File -> Manage Connections.
*. Now click New.
*. Now select the type of cable you are using. If you are using DKE-2, CA-53 [N-Series] cable, select USB.
*. Click Next. It will find your product and say FOUND. If it doesn’t find any, you can try changing your cable type by clicking Back.
*. Click Next and then Finish.
*. Now your cable type (USB) appears in the connection list. Select it. Click APPLY and then CLOSE.
*. Now select File -> Open Product.
*. A list of RM code will open. Select your phone’s RM code. Like RM-133 for Nokia N73 or RM-84 for Nokia N70 and other nokias with there corresponding Rm Types but choose the one which corresponds to your phone! Click OK. At this steps if you receive an error its okay. Just ignore it.
*. Now select File -> Scan Product.
*. Your phone’s firmware info will appear at the extreme bottom of the Phoenix window.
*. Now go to Flashing -> Firmware Update.
*. A window will open.
*. On that window click Browse button (the one with three dots)
*. A window will open with various products and various regions. Choose the region or country of your choice according to the language pack you want to install.
*. Click Ok.
*. Click Refurbish.
*. Now your actual flashing has started. Don’t touch your phone or press any button until the flashing has finished. Also don’t touch your data cable and your computer system. Remember dont Touch!
*. At the end Phoenix will tell you to remove your phone as the flashing has finished.
*. Now wait for your phone to reboot into latest firmware.
*. The flashing procedure takes 7-10 minutes

4. Flashing dead phones [Which show only white screen on startup] :
Note : You can install any firmware in dead phones whether it is latest and or the old one.
Note (Again) : You can make a deadphone if you want. Just unplug your cable while flashing.

*. The procedure is the same for flashing Dead phones.
*. Start Phoenix. Connect your phone with USB Cable (phone is off at this time).
*. Click File -> Open Product. Select your RM code from the window that appears. Click OK.
*. Click File -> Manage Connections. Select No Connection. Then APPLY and CLOSE.

*. Your phone will automatically start when the flashing finishes. After finish you can safely remove your data cable from Phone. FINISHED!!!

5. If you want to install another update to your phone after some months, first remove the previous version you installed in C:\Program files\Nokia\Phoenix\Products\
Delete all the contents of Products folder before installing a new firmware.

Updating ESET Smart Security and ESET NOD32 Virus Definition with Smart Way

2008-12-17T23:07:00.006+07:00

ESET is my favourite AV since this product receive the best AV 2006, 2007 and still top ten the best AV in 2008.

I'm using ESET product not just because that award, but also because this ESET doesn't make my system slower like Norton does.

ESET has 2 main product which is :
1. NOD32 Antivirus (the latest is ver 3)
This is an anti virus product
2. Eset Smart Security (the latest is ver 3)
This is an anti virus plus anti spyware, anti malware, and personal firewall in one bundling product.

Now back to topic, the problem with ESET is updating the latest virus definition with the slow connection (like mine). If you have unlimited, stable and fast internet connection you can leave this article now.

Still following this article ?

Okay for you who have unlimited, but slow internet connection (just like my office) here is the step :
1. Open your ESET Smart Security or NOD32 Antivirus
2. Press F5 to open configuration
3. Select update tab
4. Click Edit
5. Try one of the following server list
* http://gxrg.org/eset_upd/ (For ESET Smart Security ver 3)
* http://gxrg.org/nod_upd/ (For NOD32 Antivirus ver 3)
6. Update now.

Now for you with very limited internet connection (dial up) here is the step :
1. Download tools for offline browsing or site mirroring (in this case, im using Teleport Pro)
2. Run the program
3. Click "New Project Wizard"
4. Choose "Create a Browseable copy of a website on my hard drive"
5. Enter one of the following url
* http://gxrg.org/eset_upd/ (For ESET Smart Security ver 3)
* http://gxrg.org/nod_upd/ (For NOD32 Antivirus ver 3)
6. Choose "Everything"
7. Click finish
8. Run the project to retrieve the file and choose location to save your file
6. When all file downloaded, open your ESET Smart Security or NOD32 Antivirus
7. Press F5 to open configuration
8. Enter the path you saved earlier
9. Update now
10. For daily update, you don't have to waste another 18MB++, just open your Teleport project and click "Update Now". This method compare the file between your computer and server and make sure download only the newest file.

Oracle ADF Faces Template in JDev 10g

2008-10-28T11:29:00.001+07:00

My project (maybe almost project need this) require a template so when developing user interface, developer no need repeat adding banner, logo, application title, footer, etc. SRDemo example teach me to create template.jspx file and then copy paste this template to another jspx file. This is bad idea, because if somehow my logo changed, then i need to modified ALL of my jspx file.

So i'm start Googling to research about this. But sadly Oracle does not officially support ADF template in JDev 10g. JDev 11g does, but after some consideration we,re using JDev 10g.

After a bit research led me to ADF Region. But like i said, this is not supported so it's not covered in Oracle ADF Developer Guide book. Thanks to Edwin Biemond blog and AMIS blog to contribute great article about ADF Region.

This is a small example using ADF Region to add Branding, Copyright, MenuTab and MenuList. The point is :

Separate your static content like Branding, Copyright etc in file Branding.jspx, Copyright.jspx and so on.
Register those files with unique name in file region-metadata.xml
In your real page, call this template by invoking unique name in region-metadata.xml

Oracle JDeveloper 10g Review

2008-10-26T15:13:00.001+07:00

After 2 weeks using Oracle JDeveloper 10g, more spesific JDev 10.1.3.3, i'll share my opinion about this tools.

Here is JDev editor in my computer.

Now here is the summary :

1. JDev source code package organization is bad

Take a look image above, with JDev we can organize folder structure (look at the circle), but it should affect to source code only, not folder. Eclipse is better than JDev.

2. JDev require a lot of memory

3. JDev does not have option Close Project.
If we have a lot project with JDev, JDev will load them all while opening.

4. JDev can't make a new folder and can't copy file
This is the worst. I can't understand what in Oracle JDev team mind. This is the simple operation but JDev can't do it.

5. DataModel and UserInterface sometimes conflict
Yeah this is happened to me, in my DataModel have public_html folder and UserInterface have model folder.

6. JDev can't refresh file/folder automaticly
This is a bugs i think. If someone add/modify file using CVS then JDev can't load the new/modified file. I tried click refresh all time but not work. The only way is restart JDev.

7. JDev can't refresh offline database
I add new foreign key in the database and when i refresh offline database i can't see foreign key i added. I spent half day to analyze this. I wonder why it happened. And then i tried restart JDev and try refresh from database again and hulla the new foreign key apprear.

8. Sometimes WYSIWUG is broken

9. Good integrate with OracleDatabase
When create Java from table, it perfectly create POJO with the right relation mapping.

10. Easy to testing with Embedded OC4J
Just click run to show our work.

Overall JDev is okay if you develop with Oracle product only (ADF, TopLink, OC4J). If not, well you better use another Java IDE.

Journey to Oracle

2008-10-06T14:53:00.001+07:00

My new job is everything about Oracle.

Database : Oracle Database 11g
Tools : JDeveloper 10.1.3.3
Framework : Oracle ADF and ADF Faces
ORM : Oracle TopLink
LDAP & Security : Oracle Identity Manager and Oracle Internet Directory
Webserver : Oracle OAS OC4J

Most of them is something new for me.

So wait till i explore all of them and i'll share some article.

Goodbye PJN

2008-10-01T14:20:00.000+07:00

Red alert ...

My company, Pratama Jaringan Nusantara is going to collapse. We have no productive activity since 2 - 3 month ago.

Today electrical power is down, telephone is down and the worst internet is also shutdown.

So i think it's time to start looking a new job.

Wish me luck.

WEB4J Java Web Application Framework

2008-05-15T12:25:00.004+07:00

Another simple web framework. According to official website the primary design goal of WEB4J is to always exercise deep compassion for you, the application programmer, to make your tasks as simple, natural, and as effective as possible. The framework should take on as much pain as possible, so that, in the end, you experience as little pain as possible.

The whole point of WEB4J is to give those who use it a deep feeling of simplicity, clarity, and elegance. That feeling is the ultimate goal of WEB4J, and nothing else. This is an esthetic goal, not a technical one.

The important things about WEB4J are :

it's a full-stack Java web application framework
it's small, and has a philosophy of deep simplicity and minimalism
it can boost your productivity by 300% - 400% over other tools
it's not free, it's not open source, and it has nothing to do with Rich Internet Apps
it uses a minimal toolset
it lets you implement forms with plain HTML
it has no custom tags for form controls
it has no custom annotations
it has no custom .xml files (only web.xml is used)
it has no tedious object-relational mapping
it lets you put SQL in plain .sql text files
it can be used with any relational database that has a JDBC driver
it doesn't take you long to learn (and you don't need to buy a book)
it uses convention over configuration in several important ways
it makes your application classes simple, and easy to maintain
it allows package-by-feature, where closely related items are placed in the same directory
it places your validation logic in Model Objects (where it belongs)
it lets your Model Objects be immutable
it lets your Model Objects avoid the Java Beans anti-pattern
it requires minimal configuration
it doesn't impose thread-safety constraints on your classes
it lets multilingual apps have almost the same style as a single language app
it lets your apps assist in their own translation
it lets you place translations in the database
it lets you avoid ResourceBundle and its defects
it protects you from common hacks
it's cheaper to use than open source tools
it starts up quickly
