The document provides an overview of the DataFX framework, which facilitates data retrieval and rendering in JavaFX applications. It discusses how DataFX allows developers to focus on application logic by abstracting away things like data sources, conversion, and threading. Key aspects covered include DataSources and Readers for retrieving data from various sources; Converters for transforming data formats; DataProviders for populating Observable data in JavaFX; controller APIs for building views; and Flow APIs for linking views and handling user actions. The goal of DataFX is to simplify common tasks in building enterprise JavaFX applications that interact with real-world services and data.
This presentation takes a pragmatic approach to comparing JavaFX and HTML5, using an application written in JavaFX versus the same functionality written in HTML5 to illustrate the pros and cons of each.

Java EE 8 Web Frameworks: A Look at JSF vs MVCJosh Juneau
This session provides an overview of both the JSF and MVC 1.0 frameworks. The frameworks are then compared to each other. Finally, JSF 2.3 upcoming features are previewed.
Using the Tooling API to Generate Apex SOAP Web Service ClientsSalesforce Developers
Join us as we review the capabilities of the existing WSDL-to-Apex code generation feature, and explain how we built a tool to provide expanded features using the Tooling API. The resulting tool has greater support for more WSDL features, generates test cases and the associated mocks to maximize code coverage, and optionally includes HttpRequest versions of the callouts.
In this presentation I will go through latest features being added in Spring 3.1/3.2 one more time and also will try to look behind the scene on what new features are comming in Spring 4 which should be released at the end of this year.
This slide covers several topics, such as app startup, hilt, navigation, and datastore, which have been released this year, through Android 11 weeks.
Not only suggesting overview but also giving simple use cases.
In this session, we take a look at a handful of the features that will be part of the upcoming Java EE 8 release, as well as a few of the existing features that can be utilized in Java EE 7 today. Each of the features are presented via a recipe in the "Problem", "Solution", and "How it Works" format.
Developing enterprise applications today using JavaFX is a challenge. The industry has not matured enough to identify patterns and practices. Consequently practioners (architects and developers alike) commit the same mistakes again and again. There is a complete lack of non-UI frameworks that make JavaFX application development easy and fast. FxObjects attempts to address that gap. The 0.1 version released provides powerful features.

Some years ago development of Java Desktop applications was easy: We just downloaded Java 8 from Oracle and got a set of useful tools and framework to develop Java desktop applications:
AWT & Swing
WebStart
JavaFX
JFX Packager
If you now download a Java version from Oracle (or any other vendor) several of the mentioned tools and frameworks are gone. Some JDKs only contain AWT & Swing for desktop development and miss all the newer tools. But even if they include such tools or frameworks you have sometimes no idea about their state.
In this session I will give an overview about the differences between JDKs that you can use today and how frameworks like JavaFX are really supported by the vendors. Next to this we will have a look at all the tools that are important for building and installing desktop development. Since some like WebStart are gone you can find quite good alternatives.
Java APIs- The missing manual (concurrency)Hendrik Ebbers
This isn’t a talk about microservices, NoSQL, container solutions or hip new frameworks. This talk will show some of the standard Java APIs that are part of Java since version 5, 6, 7 or 8. All those features are very helpful to create maintainable and future-proof applications, regardless of whether JavaEE, Spring, JavaFX or any other framework is used. The talk will give an overview of some important standard concepts and APIs of Java like annotations, null values and concurrency.
Once upon a time, there was a poor, innocent language. It was friendly and kind. Everything could have been nice and peaceful, but there was another language that was grumpy and mean. One day they met and started to argue about who the better language was…. This session compares the Java language with TypeScript. It discusses how common problems are solved with these languages. At the end, you’ll see who is the beauty and who is the beast.

- What’s the best way to handle NullPointerExceptions?
- How can I write concurrent code that is still maintainable?
Multidevice Controls: A Different Approach to UXHendrik Ebbers
Everybody knows boring form-based user interfaces. What if you could add mobile devices to improve the UX of desktop or web applications? A research project at the University of Applied Sciences and Arts Northwestern Switzerland has tried to address this topic in a totally different way. Usually you would expect to rework the UI and make it fancier, but here the idea is to enhance controls so they can reside on a mobile device. For example, you can think about a text input field that gets the focus, with the actual data input being done on a mobile phone. This session presents an overview of the concept and shows you some results of the research project in the form of demos based on Swift, JavaFX, and Polymer.
Java WebStart Is Dead: What Should We Do Now?Hendrik Ebbers
Starting with Java 11, WebStart is being removed from Java. Because even today several applications are built on top of this technology, it will be mission-critical for many companies to find a replacement for it. This session presents an overview of the features of WebStart and how they can be replaced. It includes samples of several open source and commercial tools that provide such features and might mean new and cool possibilities for WebStart-based applications.

Writing a "Hello World!” application is always easy, and a Java developer can learn how to write it with JavaFX in some minutes. But if you want to create a productive application, knowledge of "Hello World!” isn't enough. A real application should be well structured, provide an automatic build that ends in usable artifacts, and contain only needed dependencies. In addition, such an application should be testable and maintainable. This session presents some general concepts regarding how you can create and structure a JavaFX application that can easily grow and become more complex without losing control of the code, functionality, and maintainability. At the end, each attendee will have a template to use to start creating JavaFX-based applications.
BUILDING MODERN WEB UIS WITH WEB COMPONENTS @ DevoxxHendrik Ebbers
This session will give you a thorough introduction into Web Components. We start by explaining the standards that form the foundation of WebComponents: Template tag, custom elements, Shadow DOM, and HTML imports. Next we will do a live coding session showing you how you can rapidly build a web application with existing Web Components from Polymer Elements and other sources and connect the application to a server. In the last section, we are going to explain how you can build your own custom components and integrate them into your application. Also we will share our experience gained while building an application with Web Components and talk about pitfalls that should be avoided when using Web Components in a real world project.
This talk shows Best Practices that can be used to develop application in an agile and feature driven workflow. Companies like flickr use this development process internally and even Martin Fowler defined a part of the process as “FeatureToggle”.
In the talk I will start with the definition of feature tasks and what steps and methods are needed to define them. Next to this an application is shown that was developed by the use of FeatureToggles. Here different architecture approaches in Java will be shown. Next to the architecture of an application the development workflows must be changed to create applications in a feature driven way, too. In some examples best practices to handle the new workflows will be shown.
Methods and tools like the GitFlow, GitLab, the Java Togglz API and Jira will be shown in this talk.
How to use Bonjour in Java
The slides show you how to create bonjour based services on server site and use them on client site. All examples are completely written in Java.
Devoxx UK 2013: Sandboxing with the Vagrant-Binding APIHendrik Ebbers
Many developers are in need of complex test environments for different projects with customers. The ideal situation would be to have them running in a sandbox. With help of Vagrant and the vagrant-binding API it's possible to create VM based sandbox-environments "on the fly".
Anytime, anywhere and above all reproducible.
The Talk shows how fast you can create and configure a sandbox with the help of Vagrant and vagrant-binding even from within the Java runtime. Based on this different solutions for problems in QA and UnitTesting will be shown.

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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

2. The Mission
In this session, you'll learn how to develop
Enterprise Applications in JavaFX with
Real-World Services and Data.
We will show how the DataFX framework
facilitates the process of data retrieval and
rendering, and how it allows you to focus
on your application-specific logic.
9. Concurrency API
JavaFX is a single threaded toolkit
You should not block the platform thread
Rest calls may take some time...
...and could freeze the application
Do not do this at home!
10. DataFX Executor
Executor executor = new ObservableExecutor();
ListView<Service<?>> list = new ListView<>();
list.setCellFactory(new ServiceCellFactory());
list.itemsProperty().
bind(executor.currentServicesProperty());
implementation ofjava.util.concurrent.Executor
bind your services to the view
11. DataFX Executor
supports title, message and progress for
each service
supports Runnable, Callable, Service &
Task
cancel services on the gui
13. Lambda Support
JDK 8 has Lambda and the awesome
Stream API
Map and reduce your collections in
parallel
But how to turn into the JavaFX
application thread?
14. Lambda Support
StreamFX<T> streamFX = new StreamFX<>(myStream);
it is a wrapper
ObservableList<T> list = ...;
streamFX.publish(list);
streamFX.forEachOrdered(final
Consumer<ObjectProperty<? super T>> action)
this will happen in the
application thread
16. DataSources
Obtain data from a variety of sources, in a
variety of formats and put the data in a
JavaFX Observable or ObservableList
Object.
Goal:
Variety of sources -> the DataReader abstracts this
Variety of formats -> the Converter abstracts this
*
*

18. DataReader
interface DataReader<T> {
T get();
boolean next();
}
Easy to
implement!
RestSource
FileSource
JDCBSource We provide this implementations
- with builder API -
21. Converter
interface Converter<T,U> {
public void initialize(T input);
public U get();
public boolean next();
}
create your
custom one
JSONConverter<T> implements
Converter<InputStream, T>
RestSource reads an InputStream, and
will ask Converter to deliver instance(s) of T
22. DataProvider
DataProviders populate JavaFX
Observable and ObservableList instances
Data is added/changed on the JavaFX
Application Thread only
Retrieval is done in a background thread,
managable via an ExecutorPool
25. DataProvider
DataProviders leverage the Observable
capabilities: content is added when it is
available
ListDataProvider will add entities to the
resulting ObservableList as long as input
can be read from the DataReader
26. DataProvider
Binding the ObservableList in a ListView
will cause the ListView to be populated
gradually
This can be leveraged in your application
logic, i.e. First retrieve the most recent or
important items
27. Writeback support
Starting in DataFX 2.0, it is possible to
make changes to retrieved data, and
send those changes back to the original
datasource
UI
Observable
external Data DataFX
28. Challenges
We don't want to write-back all changes
In many cases, write-back is more
complex than read, and not symmetrical
i.e. Authentication
needed, different
granularity
29. Writeback support
only one additional
class that handles
the writeback...
ObjectDataProvider.setWriteBackHandler(WriteBackHandler h);
ListDataDataProvider.setAddEntryHandler(WriteBackHandler h);
...and you only need
to implement one
method
30. Example
DataReader<Person> dr = new JdbcSource(....);
ListDataProvider<Person> lodp = new ListDataProvider(dr);
ObservableList<Person> myList = ...;
lodp.setResultObservableList(myList);
lodp.setWriteBackHandler(new WriteBackHandler<Person>() {...});
ok, this is the part
we already know
adding writeback support
31. Example
lodp.setWriteBackHandler(new WriteBackHandler<Person>() {
@Override
public WritableDataReader createDataSource(Person me) {
String statement = "UPDATE PERSON SET lastName='" +
me.getLastName() + "' WHERE firstName='" +
me.getFirstName() + "'";
JdbcSource<Person> dr = new JdbcSource(dbURL, statement,
null);
dr.setUpdateQuery(true);
return dr;
}
}); simple implementation of jdbc
writeback support
32. Writeback support
RestSource and JDBCSource already
implement WritableDataReader
Threading is dealt with by DataReader
implementations
Support of transient field by using
@WriteTransient
34. JAVAFX API
In JavaFX you should use FXML to
define your views
You can define a controller for the view
Link from (FXML-) view to the controller
<HBox fx:controller="com.guigarage.MyController">
<TextField fx:id="myTextfield"/>
<Button fx:id="backButton" text="back"/>
</HBox>
35. Controller API
Some kind of inversion of control
Define the FXML in your controller class
Create a view by using the controller class
Supports more annotations for the view
livecycle
convention over configuration
36. Controller API
@FXMLController("Details.fxml")
public class DetailViewController {
@FXML
private TextField myTextfield;
@FXML
private Button backButton;
@PostConstruct
public void init() {
myTextfield.setText("Hello!");
}
}
define the
FXML file
default Java
annotation
37. Controller API
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<HBox spacing="10" alignment="bottom_right">
<TextField fx:id="myTextfield"/>
<Button fx:id="backButton" text="back"/>
</HBox>
use JavaFX Scene Builder!
no controller
class is set in
FXML
38. Controller API
Provides a factory for view creation
Inject all needed Nodes with @FXML
Supports @PostConstruct
39. View Context
Controller API support 2 contexts
ApplicationContext
View Context
Inject context by using Annotation
Register your model to the context
40. View Context
public class DetailViewController {
@FXML
private TextField myTextfield;
@FXMLViewContext
private ViewContext<DetailViewController> context;
@PostConstruct
public void init() {
DataModel model = context.getViewFlowContext().
getRegisteredObject(DataModel.class);
myTextfield.textProperty().
bindBidirectional(model.getSelected());
}
}
injection
access
registered
objects
41. Conclusion
Create view with FXML
Define your model as pojo
Create a controller
bind all this by using annotations
48. Master Detail
FXMLFlowView masterView =
FXMLFlowView.create(MasterViewController.class);
FXMLFlowView detailView =
FXMLFlowView.create(DetailViewController.class);
create one FLowView for each view
use controller API internally
MasterView DetailsView
back
details
delete
51. Master Detail
Use controller API for all views
Define a FlowView for each view
link with by adding an action
add custom actions to your flow
but how can I use them?
52. Master Detail
@FXMLController("Details.fxml")
public class DetailViewController {
@FXML
@FlowAction("back")
private Button backButton;
@PostConstruct
public void init() {
//...
}
@PreDestroy
public void destroy() {
//...
}
}
controller API
defined
in FXML
bind your flow
actions by annotation
listen to the
flow
53. Flow API
share your data model by using contexts
ViewFlowContext added
@FXMLViewFlowContext
private ViewFlowContext context;
You can inject contexts in your
action classes, too
@PostConstruct and @PreDestroy are
covered by the view livecycle
54. Flow API
By using the flow API you don‘t have
dependencies between the views
Reuse views and actions
Use annotations for configuration
