Frameworks are large prewritten code to which you add your own code to solve a problem in a specific domain.
You make use of a framework by calling its methods,inheritance,and supplying “call-backs” listeners.
Spring is the most popular application development framework for enterprise Java™.
Millions of developers use Spring to create high performing, easily testable, reusable code without any lock-in.
Collections Framework is a unified architecture for managing collections, Main Parts of Collections Framework
1. Interfaces :- Core interfaces defining common functionality exhibited by collections
2. Implementations :- Concrete classes of the core interfaces providing data structures
3. Operations :- Methods that perform various operations on collections
Java applications cannot directly communicate with a database to submit data and retrieve the results of queries.
This is because a database can interpret only SQL statements and not Java language statements.
For this reason, you need a mechanism to translate Java statements into SQL statements.
The JDBC architecture provides the mechanism for this kind of translation.
The JDBC architecture can be classified into two layers :
JDBC application layer.
JDBC driver layer.
JDBC application layer : Signifies a Java application that uses the JDBC API to interact with the JDBC drivers. A JDBC driver is software that a Java application uses to access a database. The JDBC driver manager of JDBC API connects the Java application to the driver.
JDBC driver layer : Acts as an interface between a Java applications and a database. This layer contains a driver , such as a SQL server driver or an Oracle driver , which enables connectivity to a database.
A driver sends the request of a Java application to the database. After processing the request, the database sends the response back to the driver. The driver translates and sends the response to the JDBC API. The JDBC API forwards it to the Java application.
Welcome to presentation on Spring boot which is really great and relatively a new project from Spring.io. Its aim is to simplify creating new spring framework based projects and unify their configurations by applying some conventions. This convention over configuration is already successfully applied in so called modern web based frameworks like Grails, Django, Play framework, Rails etc.
The modern view on implementation of classic design patterns in JavaMikalai Alimenkou
Almost every developer heard about design patterns. They was introduced long time ago to solve particular set of repeating problems in systems of different complexity level and size. But there is an opinion that many design patters just filled holes in the OOP languages of that time. Java as one of them has transformed and improved significantly in the last 10 years. So may be we could review design patterns implementation in modern Java world? Some of them are now may be easily replaced with language idioms, some others may be covered with existing libraries and frameworks. I'm sure you know some design patterns that are dead now or became anti-patterns in their initial implementation. Lets make this fun and useful review together!

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. What is Spring DAO (Data Access Object)
DAO is used to read and write data to and from database
respectively.The table below shows the responsibility of Spring and
User.
Note : The Spring Framework takes care of all the low-level details that
can make JDBC such a tedious API to develop with
3. Action Spring User
Define Connection Parameter Yes
Open the Connection Yes
Specify the SQL statement Yes
Declare parameters and provide parameter values Yes
Prepare and Execute the Statement Yes
Set up the loop to iterate through the result (if any) Yes
Do the work for each iteration Yes
Process any Exception Yes
Handle Transactions Yes
Close the Connection,Statement and ResultSet Yes
4. Steps for DAO
We have to follow three steps while configuring the Spring Context in
XML.
Step 1: Configure Data Source
1. Driver Based Data Source
2. JNDI Data Source
3. Pooled Data Source
Step 2: Configure JDBC Template
1. JDBC Template
2. NamedParameter JDBC Template
3. Simple JDBC Template
5. Step 3: Configure custom DAO Class
Step 1: Configure Data Source
The very first step you need to work on database is configuring the data
source in Spring’s context file. If you remember the basic steps of JDBC
Connection in Java, first we load the driver using Class.forName(), then
getting connection using DriverManager providing the URL such as
Connection con = DriverManager.getConnection(, ,) and then using
Statement or PreparedStatement. While configuring the DataSource in
Spring we may need to pass connection details (such as DriverName,
URL, Username, Password) to Spring framework. The benefit of
configuring data sources in this way is that they can be managed
completely external to the application, leaving the application to simply
ask for a data source when it’s ready to access the database.
6. 1. Driver Based Data Source
It is the simplest data source that can be configured in Spring. This
should not be used in Production but it is good to use in Development
Environment for unit testing. There are Two data source classes.
• DriverManagerDataSource
• SingleConnectionDataSource
The basic difference is DriverManagerDataSource provides a new
connection each time, where as SingleConnectionDataSource provides
the same connection. Let’s see an example, to connect MySQL
database I am using com.mysql.jdbc.Driver class. And don’t need any
username or password. We use DriverManagerDataSource so the
configuration would be:
8. How it is if we take the connection details (Driver class name, url,
username, password etc. ) from a property file rather than defining in
Spring Context XML file itself?
Yes, it is a good idea to take the database connection details from a
property file. So let’s create a property file. We will name the file as:
jdbc.properties
9. You need this extra entry to include the properties from jdbc.properties file.
Properties define in jdbc.properties file
10. 2. JNDI (Java Naming and Directory Interface) DATA SOURCE
Application server are often pooled for greater performance. The
application servers such as WebSphere, WebLogic, Jboss allow to
configure connection pools. And these connection pools can be
retrieved through a JNDI. The benefit of configuring data sources in this
way is that they can be managed completely external to the application,
leaving the application to simply ask for a data source when it’s ready to
access the database.
In driver based data source, we saw any of the 2 classes
DriverManagerDataSource and SingleConnectionDataSource can be
used to establish the connection. Similarly for JNDI data source, we use
JndiObjectFactoryBean.
11. I have created a connection pool my application server. The JNDI name
is “mysqldatasource”. There is a servlet deployed in the same Server
which gets the DAO object from the Spring Container. Spring provided
the dataSource to the DAO after getting connection from the
connection-pool mysqldatasource.
12. 3. Pooled Data Source
If you’re unable to retrieve a data source from JNDI, the next best thing
is to configure a pooled data source directly in Spring. Spring doesn’t
provide a pooled data source, there’s a suitable one available in the
Jakarta Commons Database Connection Pools (DBCP) project. To add
DBCP to your application, you need to download the JAR file and place
it into your build path along with spring library files.
The class you do use for Pooled Data Source is :
org.apache.commons.dbcp.BasicDataSource
14. Step 2: Configure JDBC Template
After configuring the DataSource, the next step is configuring the
JDBCTemplate. The JdbcTemplate class is the central class in the
JDBC core package. It simplifies the use of JDBC since it handles the
creation and release of resources. This helps to avoid common errors
such as forgetting to always close the connection. It executes the core
JDBC workflow like statement creation and execution, leaving
application code to provide SQL and extract results. This class executes
SQL queries, update statements or stored procedure calls, imitating
iteration over ResultSets and extraction of returned parameter values. It
also catches JDBC exceptions and translates them to the generic, more
informative, exception hierarchy defined in the org.springframework.dao
package.
15. Option 1: The JdbcTemplate can be used within a DAO implementation
via direct instantiation with a DataSource reference
OR
Option 2: be configured in a Spring IOC container and given to DAOs as
a bean reference.
Option 1: Explanation
The JdbcTemplate within a DAO implementation via direct instantiation
with a DataSource reference.
18. Step 3: Writing DAO Layer
We already discussed that the JdbcTemplate can be used within a DAO
implementation via direct instantiation with a DataSource reference OR
be configured in a Spring IOC container and given to DAOs as a bean
reference. Now we will see how they can be implemented in the DAO
class.
Option 1: The JdbcTemplate within a DAO implementation via direct
instantiation with a DataSource reference.
19. We are injecting
DataSource but not
JDBCTemplate
In DAO Class
Created JDBCTemplate
instance and assign to
localobject
Using
JDBCTemplate
20. Option 2:
Configured in Spring IOC container and given JdbcTemplate to DAOs
as a bean reference.
Explanation :
In all our examples, we adopted this option only…
21. In DAO Class
Bean id must be
JDBCTemplate
JDBCTemplate not
DataSource
