Spring-
Spring framework is an open source Java platform that provides comprehensive infrastructure support for developing robust Java applications very easily and very rapidly. Spring framework was initially written by Rod Johnson and was first released under the Apache 2.0 license in June 2003.
Spring provides a very clean division between controllers, JavaBean models, and views.
Spring's MVC is very flexible. Unlike Struts, which forces your Action and Form objects into concrete inheritance (thus taking away your single shot at concrete inheritance in Java), Spring MVC is entirely based on interfaces. Furthermore, just about every part of the Spring MVC framework is configurable via plugging in your own interface. Of course we also provide convenience classes as an implementation option.
Spring, like WebWork, provides interceptors as well as controllers, making it easy to factor out behavior common to the handling of many requests.
Spring MVC is truly view-agnostic. You don't get pushed to use JSP if you don't want to; you can use Velocity, XLST or other view technologies. If you want to use a custom view mechanism – for example, your own templating language – you can easily implement the Spring View interface to integrate it.
Spring Controllers are configured via IoC like any other objects. This makes them easy to test, and beautifully integrated with other objects managed by Spring.
Spring MVC web tiers are typically easier to test than Struts web tiers, due to the avoidance of forced concrete inheritance and explicit dependence of controllers on the dispatcher servlet.
The web tier becomes a thin layer on top of a business object layer. This encourages good practice. Struts and other dedicated web frameworks leave you on your own in implementing your business objects; Spring provides an integrated framework for all tiers of your application.
The RA framework provides a Java-based n-tier architecture for quickly developing web applications. It includes presentation, middleware, business, and data interface layers. The presentation layer generates user interfaces from middleware data. Middleware uses XML configuration instead of Java beans. Business logic is implemented as services. The data interface layer integrates with databases using Oracle or Hibernate frameworks. The framework aims to reduce development time through reusable and configurable components while ensuring reliability, reusability, maintainability and portability.
This document discusses enterprise architecture types and Java EE. It describes single, two, and three-tier architectures. It also discusses n-tier architecture and the advantages it provides. Finally, it provides an overview of Java EE, including its benefits, features, runtime infrastructure, APIs, containers, and the process for developing a Java EE application.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
2. Understanding Java Platforms

7. The Java Runtime Environment
Java Hotspot Client Virtual Machine
Java Hotspot Server Virtual Machine
Adaptive compiler
Improved memory allocation and garbage collection
Thread synchronization
7
9. Deployment Technologies
• Java Plug-in :
Java Plug-in technology, included as part of the Java
Runtime Environment, Standard Edition (Java SE),
establishes a connection between popular browsers and
the Java platform. This connection enables applets on
Web sites to be run within a browser on the desktop.
9
10. Java Web Start Technology
• Using Java Web Start technology, standalone Java
software applications can be deployed with a single click
over the network.
• Java Web Start ensures the most current version of the
application will be deployed, as well as the correct version
of the Java Runtime Environment (JRE).
10
11. Java Control Panel
• It allows you to view and set a wide range of parameters
controlling how Java runs on your computer.
11
12. Java Update Mechanism
• The Java Update is a feature that keeps your computer
up-to-date automatically with the latest Java releases.
• Installing the Java Runtime Environment automatically
installs the Java Update feature.
12
15. Configurations
• Java ME has two configurations: the Connected Device
Configuration (CDC) and the Connected Limited Device
Configuration (CLDC).
• These configurations contain a virtual machine containing
a small but focused set of libraries making up the runtime
environment
15
16. Profiles
• Profiles are necessary to work in conjunction with
configurations as part of the necessary runtime
environment.
• Profiles are APIs that define the application‘s life-cycle
model, user interface, and device properties access.
• CDC contains the Foundation Profile (FP), the Personal
Profile (PP), and the Personal Basis Profile (PBP).
• PBP is a subset of PP.
• The CLDC contains the Mobile Information Device Profile
(MIDP) and the Information Module Profile (IMP).
• IMP is a subset of MIDP.
16
17. Java Platform Enterprise Edition
• The Java Platform, Enterprise Edition provides a means
to create true enterprise systems that are flexible,
scalable, and secure.
• A major benefit of enterprise systems is the separation of
software components. Java EE follows the Model-ViewController (MVC) architecture where servlets work as the
controller, JavaServer Pages handle the view or
presentation logic, and the business logic is represented
as the model, typically the Enterprise JavaBeans (EJBs)
17
18. • A Java Specification Request (JSR) is the description of
Java platform–related specifications—proposed and final.
• Enterprise Java Beans 2.1
• Servlet 2.4
• JavaServer Pages 2.0
• Java Message Service 1.1
• JavaMail 1.3
• Web Services 1.1
• JAX RPC 1.1
18
20. Working with the Java Remote
Method Invocation API
• Exam Objective 6.2 Describe at a high level the benefits
and basic characteristics of RMI.
20
21. •Client stubs
The ‗rmic‘-created stub for the client side is called a ―stub.‖
When using JDK 1.4 and earlier versions (prior to JDK 5.0), you are required to use the ‗rmic‘ utility to
generate stub classes.
In JDK 5.0 and later, the RMI runtime generates the stub classes automatically (by constructing a proxy).
The client stub‘s marshal method calls the name and arguments and sends them to the skeleton on the
server side.
After they receive the results from the sender, they return the result back to the method call invoker.
•Server stubs (skeletons)
The ‗rmic‘-created stub for the server side is called a ―skeleton.‖
As of JDK 1.2 and later, skeletons are no longer needed.
The server stub‘s receive marshal method calls the name and arguments from the client stubs, performs the
necessary operations, and returns the result back to the client stub.
21
22. • Java Remote Method Invocation over Internet Inter-Orb
• Protocol (RMI-IIOP) is used for Java to non-Java distributed
computing solutions. Java-IDL is used by Common Object
Request Broker Architecture (CORBA) developers to provide a
CORBA to Java distributed computing solutions.
• You should not see RMI-IIOP or Java-IDL on the exam.
22
23. Working with Database Technologies
• Exam Objective 6.3 Describe at a high level the benefits
and basic characteristics of JDBC, SQL, and RDBMS
technologies.
23
24. Working with Database Technologies
• A Relational Database Management System (RDBMS) is
a type of database management system that organizes its
data in the form of interrelated tables.
>
>
>
>
>
Benefits of an RDMBS include the following:
Provides a persistent data store
Processes SQL queries
Manages users
Performs backups and restores
24
25. Structured Query Language
• Operations to support querying/retrieval of information from relational
databases.
• Operations to support modification for example, insertion, updating,
and deletion of information in relational databases.
• Operations to support the management of relational databases.
• Operations to support execution plans. An execution plan is
generated by the RDBMS to specify how it will execute a piece of
application code.
• Operations to support stored procedures. A stored procedure is a
piece of application code that is stored and executed within the
database.
• You will get an execution plan as a result of compiling a stored
procedure.
25
26. Working with Additional Java Integration APIs
• Exam Objective 6.4 Describe at a high level the benefits
and basic characteristics of JNDI, messaging, and JMS
technologies.
26
28. • JNDI lays out its elements as a tree structure of directories and
objects.
• When creating a connection, you need to establish an initial
base context. Think of the context as the directory starting point
in the tree.
• You may change the context whenever you like.
• However, when the context is set, you can only traverse the
• downward portion of the tree when performing querying
operations.
28
29. • The Java Message Service (JMS) API resides in the javax.jms
package.
• This API is used to access the common features of enterprise
messaging systems. The JMS API allows for the creation,
sending, receiving, and reading of messages with Java EE
application components.
• All of this distributed-computing communications of separate
applications is done asynchronously this is essentially the
definition of a messaging system.
29
30. The Publish/Subscribe Messaging Model
• Publish/subscribe messaging is based on events. Consumers
subscribe to events of interest by specifying a topic that is part
of a set of messages.
• The producers of these messages will route these messages to
the consumers who register for them.
• The consumers will then consume the events when they arrive.
30
31. The Point-to-Point Messaging Model
• Point-to-point (PTP) messaging involves applications
routing messages to consumers while using a shared
queue.
• The consumer maintains this queue of awaiting
messages, and the messaging application sends
messages to that queue.
31
