- Java is a high-level, compiled programming language that is platform-independent and can be executed by a Java Virtual Machine (JVM) on any device.
- J2EE (Java Platform, Enterprise Edition) is a Java standard for developing multi-tier enterprise applications. It includes APIs and specifications for components like servlets, JSP, EJBs, and more.
- Application packaging involves bundling Java code and dependencies into standardized archive files like JAR, WAR, and EAR for easy deployment and management across environments. Deployment descriptors configure applications.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

3. Java Fundamentals
Java
What is Java?
Programming Language :
They are set of code which performs a particular task
Ex : code to multiply 2 number / code to get a variable and process it ..
Programming Languages classification
• High level language vs low level language
• Compiler based vs Interpreter based
Java is high level compiler based language
Code.java (source) > compiled (using javac) > code.class > gets executed by JVM
.java files are human readable files
.class are JVM understandable files

• For a Java code to run/execute JRE is enough
• Latest version of JDK is Java8
• Java needs executed with Java Parameters
• Basic java parameters Min Heap size, Max Heap Size and Server variable
• -Xms and –Xmx, -Xms 512 -Xmx 2048

for modular construction of enterprise applications. The EJB
specification is one of several Java APIs in the Java EE
specification. EJB is a server-side model that encapsulates the
business logic of an application.

Application packaging
“Application packaging is packing the java code in form a archive ,
its contents contain environmental references, Deployment
descriptors, java Source code and static contents “
The main uses of packaging the application are
• Avoid corruption of java files and file loss
• Easy to transfer between servers and environments
• Easy to deploy
• Easy to access the classes
Types of Packages
• JAR – Java Archive
• WAR – Web Archive
• EAR – Enterprise Archive

“A deployment descriptor (DD) refers to a configuration file for
an artifact that is deployed to some java container”
• The deployment descriptor must be called web.xml and must reside
in the WEB-INF directory in the web application root.
• For Java EE applications, the deployment descriptor must be named
application.xml and must be placed directly in the META-INF
directory at the top level of the application .ear file.

Class loaders
What are Class Loaders ?
Class loaders find and load class files. Class loaders enable applications that
are deployed on servers to access repositories of available classes and
resources.
Application developers and deployer must consider the location of class and
resource files, and the class loaders used to access those files, to make the files
available to deployed applications
Types of class loading
