In this modern life everybody has to do lots of tasks during their day to day life. And its very important to remember and handle these tasks. There are so many ways this. Ofcourse one simple ways is the to-do list managers. And for a person who’s work is related to Computer field the web based manager is the best option. Lots of to-do list manager applications are available in the web now. Most of them have a great, easy usable interface and have it’s own unique features. Among those to-do list managers am listing three here. Yea these are my favorites…

Orchestrate‘ is following a unique method to help you ogranize your to do lists. Its very simple and eye catching one. Rather then simply allowing you to create a list, it lets you create multiple lists each with their own name. Orchestrate then allows you to select the ones you want to see and display them in your little workspace. You can have them all open at once or just a select few, as well as get a basic overview of all lists. Orchestrate has a neat interface with a lot of your usual Web 2.0 type design elements with Ajax and Javascript animations.

Remember the Milk‘ allows you to organize your tasks into tabs and tags, make time specific tasks with automatic reminders and repeat intervals, and even has collaborative features. Remember the Milk may have a lot of functionalities. Although, even if you use it with the bare-minimum functionality, you’ll eventually start using all the features. Its has a gadget to the Google personalized desktop and which will be very helpful for a google desktop user.

This is very helpful for a person who is working in different projects at a time. Or we can divide the task to different projects to manage.

‘Hibernate Dialect property’ for Different Databases

Hibernate is the most common and famous ORM using these days. It has a property called “Dialect” through which we tells Hibernate that we are using ‘this specific’ database. Here in this post you can see the dialect property values which we have to give for different databases. You can read more about this from here

* DB2 - org.hibernate.dialect.DB2Dialect
* HypersonicSQL - org.hibernate.dialect.HSQLDialect
* Informix - org.hibernate.dialect.InformixDialect
* Ingres - org.hibernate.dialect.IngresDialect
* Interbase - org.hibernate.dialect.InterbaseDialect
* Pointbase - org.hibernate.dialect.PointbaseDialect
* PostgreSQL - org.hibernate.dialect.PostgreSQLDialect
* Mckoi SQL - org.hibernate.dialect.MckoiDialect
* Microsoft SQL Server - org.hibernate.dialect.SQLServerDialect
* MySQL - org.hibernate.dialect.MySQLDialect
* Oracle (any version) - org.hibernate.dialect.OracleDialect
* Oracle 9 - org.hibernate.dialect.Oracle9Dialect
* Progress - org.hibernate.dialect.ProgressDialect
* FrontBase - org.hibernate.dialect.FrontbaseDialect
* SAP DB - org.hibernate.dialect.SAPDBDialect
* Sybase - org.hibernate.dialect.SybaseDialect
* Sybase Anywhere - org.hibernate.dialect.SybaseAnywhereDialect

Commonly used Generators in ‘Hibernate’

Generator Description
increment It generates identifiers of type long, short or int that are unique only when no other process is inserting data into the same table. It should not the used in the clustered environment.
identity It supports identity columns in DB2, MySQL, MS SQL Server, Sybase and HypersonicSQL. The returned identifier is of type long, short or int.
sequence The sequence generator uses a sequence in DB2, PostgreSQL, Oracle, SAP DB, McKoi or a generator in Interbase. The returned identifier is of type long, short or int
hilo The hilo generator uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a table and column (by default hibernate_unique_key and next_hi respectively) as a source of hi values. The hi/lo algorithm generates identifiers that are unique only for a particular database. Do not use this generator with connections enlisted with JTA or with a user-supplied connection.
seqhilo The seqhilo generator uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a named database sequence.
uuid The uuid generator uses a 128-bit UUID algorithm to generate identifiers of type string, unique within a network (the IP address is used). The UUID is encoded as a string of hexadecimal digits of length 32.
guid It uses a database-generated GUID string on MS SQL Server and MySQL.
native It picks identity, sequence or hilo depending upon the capabilities of the underlying database.
assigned lets the application to assign an identifier to the object before save() is called. This is the default strategy if no <generator> element is specified.
select retrieves a primary key assigned by a database trigger by selecting the row by some unique key and retrieving the primary key value.
foreign uses the identifier of another associated object. Usually used in conjunction with a <one-to-one> primary key association.

Three advantages of integrating Struts into Spring

Three advantages of integrating Struts into Spring

There are so many advantages of integrating a Struts application into the Spring framework. These three points I got from Mr.George Franciscus’s article in Developerworks.

1. Spring was explicitly designed to resolve some of the real-world problems of JEE, such as complexity, poor performance, testability, and much more.

2. The Spring framework includes an AOP implementation that lets you apply aspect-oriented techniques to normal object-oriented code.

3. Some might say that the Spring framework just handles Struts better than Struts handles itself :)

Three ways to integrate Struts applications with Spring

1. Use Spring’s ActionSupport
2. Override the RequestProcessor
3. Delegate action management to Spring
