Summary

The document compares the Eclipse and NetBeans rich client platforms. It summarizes that Eclipse uses the OSGi container but Agile Client moved to NetBeans due to SWT bugs in Eclipse. While NetBeans sacrifices some backend purity, it fixes end-user visible bugs by being fully Java-based rather than using SWT. The document also lists pros and cons of each platform, with NetBeans being fully Java but having less OSGi support, while Eclipse has more OSGi module support but uses the proprietary SWT graphics system.

Building software using Rich Clients Platforms Rikard ThulinRikard Thulin

This document discusses building software using rich client platforms. It covers the needs of advanced rich clients including time-to-market, focusing on business logic, usability, flexible deployment, and solving application architecture problems. Several rich client frameworks are described including Eclipse RCP and NetBeans RCP. Real-world experience using NetBeans RCP is shared, noting initial investment but benefits including modularity, community support, and improved UI quality. In conclusion, rich client frameworks help avoid reinventing the wheel and provide better solutions than writing all infrastructure code from scratch.

Features of java 02University of Potsdam

Java has many features that make it a popular programming language, including being platform independent, object-oriented, robust, and secure. It is platform independent because Java code is compiled into bytecode that can run on any system with a Java virtual machine. It is object-oriented because it organizes programs around objects that contain both data and behaviors. Java is also robust through features like automatic garbage collection and exception handling. Additionally, it is secure due to features such as lack of pointers, bytecode verification, and a security manager.

Java ide comparisionRaj

The document compares several Java IDEs based on their features and suitability for J2EE development. It evaluates Netbeans, Eclipse, IntelliJ IDEA Community Edition, and IntelliJ IDEA Ultimate Edition. It finds that IntelliJ IDEA has the most features out of the box but is commercial. Netbeans and Eclipse are free and also have equivalent J2EE features, though Eclipse may require more plugins. The document concludes that for simplicity Netbeans is best if cost is a concern, while Eclipse is lightweight with good plugin support.

Multi-Configuration support in MTJgustavoeliano

The document discusses multi-configuration support in MTJ (Mobile Tools for Java) to help developers deal with device fragmentation in Java ME applications. It describes how MTJ allows defining multiple configurations for a project, each targeting a different device or symbol set. Code is preprocessed based on the active configuration. Content assist helps with preprocessing directives and symbols. A demo was provided of managing configurations and switching between them for preprocessing and building projects.

This document compares and contrasts the Java and .NET programming languages. Some key points: - Java was created by Sun Microsystems (now owned by Oracle) and is a platform-independent, object-oriented language. .NET was created by Microsoft and primarily runs on Windows. - Java uses a Java Virtual Machine (JVM) while .NET uses the Common Language Runtime (CLR). Both convert bytecode to machine code. - Java supports multiple languages like Java but .NET supports additional languages like C#. - Other differences include platforms supported, virtual machines used, important components, versions, and file extensions. Both aim for interoperability, portability and security but achieve it in different ways

Java is a powerful and versatile programming language that can be used to create desktop, web, and mobile applications. It is derived from C and C++ but uses object-oriented programming. Java applications run in a virtual machine (JVM) which makes Java cross-platform and sandboxed for security. Popular uses of Java include web applications built with technologies like JSP, Servlets, and Spring that run on application servers, as well as desktop programs and smaller applications for devices.

PDE builds or MavenEclipse Day India

Ankur Sharma has worked with Eclipse for 8 years, previously as a committer and co-lead for the Eclipse PDE project. He is currently employed by EMC2. The document discusses the challenges of builds, particularly dependency and versioning issues. It compares PDE builds and Maven builds, noting that PDE builds better understand Eclipse artifacts but Maven has advantages for dependency management and integration with source control systems and CI/CD. The conclusion is that there is no single best approach and the choice depends on the complexity and needs of the application.

JRE , JDK and platform independent nature of JAVAMehak Tawakley

Java programming language was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems. JRE stands for Java Runtime Environment which is used to provide an environment at runtime. JVM or Java Virtual Machine is the medium which compiles Java code to bytecode which gets interpreted on a different machine and hence it makes it Platform/ Operating system independent. JDK (Java SE Development Kit) Includes a complete JRE (Java Runtime Environment) plus tools for developing, debugging, and monitoring Java applications.
