JSF Vs Struts Post Your Responces as comments.

I worked on Struts 1.x i felt it was easy. Now I am working on JSF with JBoss Portlets its looks little bit complicated while development. Why its looking like that? Is really JSF is complex when compared to Struts?

 In struts I used to have request and response in My hand so that i felt every thing was in my hand to control the application.

 But Jsf with Portlets is not like that. We need to work around to get the request and response objects.But handling these request and response objects is not as easy as in struts.

I feel working with Jsf and portlets is little bit difficult when I compare  struts frame work.

Is Jsf complex or Jsf with portlets combination is complex ?

Can you please let me know when to go for JSF with portlets otherwise with struts.

WI FI Beacame old then whats new?

Wi Fi stands for Wireless Fidelity and is used to define any of the wireless technology.

Recently in Jan 2010 Intel introduced a laptap which contains the technology called Wi Di.

Wi Di stands for wireless Display.

With Wi Di you can watch the movie in your TV while dowloading in your laptop.

Why to to wait lets enjoy the movie on the big screen.

I hope this will be a big hit for the intel.

Wish the intel to bring more such advanced technologies in to the world.

Step 7: import the database

            imp file=empuser.dmp fromuser=scott touser=empuser log=temp.log commit=y


These are the basic steps which i fallow while importing. These are not enough some times while importing and you can use several other methods to import the database.

WEB 3.0

The next generation of the web is WEB 3.0 .

The applications will make the user to feel comfortable and easier.

Many of the experts believe that the Web 3.0 browser will act like a personal assistant. In web 3.0 as you search the Web, the browser learns what you are interested in. The more you use the Web, the more your browser learns about you and the less specific you'll need to be with your questions. Eventually you might be able to ask your browser open questions like "where should I go for lunch?" Your browser would consult its records of what you like and dislike, take into account your current location and then suggest a list of restaurants.

The third web 3.0 search engines will take a great revolution in the web. The web 3.0 search engines searches phrases along with the words. This will act like human brain to summarize the results obtained by it.

As you heard the word web 3.0 you may think like what is web 1.0 or what is web 1.0 .

The term web 2.0 is coined by O'Reilly media. After knowing web 2.0 word people used to think about web 1.0 . With out confusion these terms are purely related to the web.

Web1.0 :

Web 1.0 is just like a library from there user can read the information and view the images. For the web 1.0 applications you cannot contribute the information.

Web 2.0:

Web 2.0 allows user to interact with the content on the web and he can share his content on it. The user will get rich experience with web 2.0.

As per the experts the web 3.0 should give every thing by depending on your like and dislikes. As per conversation this might look interesting and it may give good feel to visualize but it will give the headache for the experts while designing and developing.

WEB 2.0

Web 2.0 is commonly used term in the software industry. Most of the people search in the web for this word. Most of the people tries to know about this word. why?

The term Web 2.0 purely related to the web application/Internet applications. As per Wikipedia "A Web 2.0 site allows its users to interact with other users or to change website content, in contrast to non-interactive websites where users are limited to the passive viewing of information that is provided to them".

The web 1.0 applications are the applications which gives information to the user but it won't interact with the user decision. In web 2.0 applications user interacts with the application and he share his decisions, he can own data and he can have control over data .

Web 2.0 sites may have an "Architecture of participation" that encourages users to add value to the application as they use it. Some people calls Web 2.0 as the “participatory Web” and Web 1.0 as “Informatory Web”.

Where we need to Store images, in SQL database or in separate folder while development?

These two ways are OK. My suggestion is to store images into sql database if there are no much more images, otherwise, it's better store them into file system because you can store them no matter how many there are.

Advantages of Storing BLOB Data in the Database:

Storing BLOB data in the database offers a number of advantages:

It is easier to keep the BLOB data synchronized with the remaining items in the row.

1. BLOB data is backed up with the database. Having a single storage system can ease administration.
2. BLOB data can be accessed through XML support in SQL Server 2005, which can return a base 64–encoded representation of the data in the XML stream.
3. SQL Server Full Text Search (FTS) operations can be performed against columns that contain fixed or variable-length character (including Unicode) data. You can also perform FTS operations against formatted text-based data contained within image fields—for example, Microsoft Word or Microsoft Excel documents.

Disadvantages of Storing BLOB Data in the Database:

Carefully consider what resources might be better stored on the file system rather than in a database. Good examples are images that are typically referenced via HTTP HREF. This is because:

1. Retrieving an image from a database incurs significant overhead compared to using the file system.
2. Disk storage on database SANs is typically more expensive than storage on disks used in Web server farms. 

 Storing Image in a folder:

Storing Image in a folder and using URL or relative path in the database is the way I would recommend. They are having many advantages and here are some of them.

1. Normally sql server space is more expensive than ordinary disk space in hosting environment.
2. You can name images in a Search Engine optimized way
3. Essay to manage, backup and restore images and database.
4. More suitable for static pages, (if you optimize some pages for performance).

As per my opinion  storing images in the folder is more acceptable.
