Extending EGL with New Cool Web 2

IBM Rational Software Development Conference 2008 Agenda for today § Background 4 Benefits of EGL 4 Impact of Web 2. 0 on application development and delivery § Values of EGL Rich UI § Demos § Conclusions 2

IBM Rational Software Development Conference 2008 First, some Context: Software delivery challenges Business focus § Responsiveness as a key competency § Effectiveness of people as a critical success factor § Revenue growth with cost containment Software delivery challenges § Keeping software projects aligned with changing business priorities § Delivering better business results within the constraints of current investments and skill sets § Effectively managing business and technical risk § Dealing with increasing complexity 3

IBM Rational Software Development Conference 2008 Rich Web Applications § People want “cool” technologies: Dojo, Google Maps, etc. § Browsers are ubiquitous and more powerful § Reap the benefits of Client-Server architectures: 4 Presentation logic moves to browser 4 Server concentrates on business and data logic 4 Server bandwidth and response times increase § Many low-level technologies to learn: 4 Java. Script, HTML, CSS, Ajax, Dojo, Silver. Light, SOAP, WSDL, Flex, XML, JSON, Google Maps, HTTP, etc 4 Focus is on “how” instead of “what” § EGL Rich UI hides these details and complexities: 4 Focus is on “what” instead of “how” 4 Improves developer productivity 4 Easily extensible with new technologies 4

IBM Rational Software Development Conference 2008 Three Main Benefits of the EGL Language PORTABLE § Java, SOA, Cobol, System Z/I/P, Browser, . . . § Optimal native deployment to any platform § Easy inter-operability with legacy § High productivity with equal flexibility § Language simplicity and robustness § Immediately useable by business developers ABSTRACT SIMPLE § Effectively hide technical complexity § Use declarative approach to everything § Support emerging standards 5

IBM Rational Software Development Conference 2008 What’s the Buzz? § Rich Internet Applications 4 Rich like a desktop application (widgets, interaction, responsiveness) 4 Data on server, syntactical validation in client 4 Orchestration moves to browser: mashups, more flexible solutions § Deployment Model 4 Install on a server once, all clients automatically get the new version 4 Ease of use, no installation required, great for situational consumption § Operational Advantages 4 Logic moves from server to client, reducing load on server 4 Stateless logic, more opportunity for caching/virtualization 4 Less complexity on server, reduce provisioning costs 6

IBM Rational Software Development Conference 2008 Rich Internet Applications Challenges § Complex to build, many details to consider § Many technologies and incompatibilities in browser: 4 Core concepts: Java. Script, HTML, CSS, Ajax, SOAP, JSON, XML 4 Presentation logic: Dojo, Silver. Light, Flex, Volta, GWT 4 Backend technologies: SOAP, XML, JSON, PHP/C#/Java, J 2 EE 4 Common issues: performance, security, consumability, support § Required technologies operate on a very detailed, low level § Metaphors and abstractions are hard to mix and match § Require highly skilled adaptable software hackers § Matching skills with traditional business developers is hard 7

IBM Rational Software Development Conference 2008 What are the key Elements of the EGL Rich UI Programming Model? With earlier versions of IBM Rational Business Developer, EGL source code can already be translated into Java and COBOL for deployment on System Z and I servers. The same EGL code allows easy access to databases and existing programs written in COBOL, Java, PL 1, and RPG. That makes EGL a perfect language for doing enterprise modernization and successfully SOA-enabling legacy applications. In addition to COBOL and Java, EGL Rich UI now adds the ability to also generate Java. Script, that then runs in a web browser and that accesses logic on the server using Services calls. The resulting Java. Script allows for mashups of various data sources being integrated inside the browser by simple code written in EGL. Existing Java. Script libraries can also be easily exposed in EGL and used in compositions thereafter. The Java. Script that is generated from the EGL, and any dependent native Java. Script libraries can be deployed to various application servers, such as Web. Sphere Application Server and Apache Tomcat. However, EGL Rich UI runs just as well on lightweight stacks, such as the LAMP stacks that just rely on an Apache HTTP Server. EGL Rich UI applications run in the most prominent browsers, such as Internet Explorer, Firefox, and Safari. The latter one is especially interesting to many people, as it is the browser that is included with the i. Phone. When used end to end, EGL can be used as a very productive technology to modernize user interfaces and leverage existing investments in software and hardware, but also in people skills. 10

IBM Rational Software Development Conference 2008 How does EGL integrate with other Technologies like Flex, Silverlight, or Dojo? HTML and Java. Script by themselves make it hard to develop highly interactive, complex applications that manage state, services, and presentation. Various solutions have risen to the surface to fill the gap. Both Flex and Silverlight are examples where a new programming runtime was developed from scratch to write rich clients in, and the browser is just used as a transport and hosting mechanism. The actual application logic and presentation code runs inside a browser add-on and interaction from normal HTML and Java. Script is provided through a special Java. Script API. EGL Rich UI uses that API to integrate with technologies like Flex and Silverlight so that these technologies can be seamlessly integrated into a comprehensive solution. Dojo is a different story. It does not require any browser add-on but instead is implemented as a regular Java. Script library. Dojo offers both a component model and a set of rich widgets, some of which have fairly advanced support for management of application data. Dojo is quickly becoming a de facto standard for many web presentation components in IBM products, such as the new and exciting Jazz platform and Project Zero. Dojo is a very powerful solution, but being a Java. Script technology, dojo tends to expose many complexities of browser-based applications, such as the quirky Java. Script language, CSS styling, and figuring out how to do HTML layouts using divs and tables. Java. Script has its uses but is not for everyone. The same is true for both Flex and Silver. Light that use complex languages such as Action. Script and C# for doing event handling and doing things like validation of inputs. In contrast, EGL Rich UI allows people to focus more on the "what" rather than the "how". The composition of user interfaces is much more declarative using EGL Rich UI, allowing developers to focus more on their intent rather than on technical details, making them much more productive then when they would use complex solutions like Java. Script. Developers can still reach out into the native Java. Script layer if they really need to, but EGL Rich UI offers a much smoother progressive disclosure story. Things are simple when they need to be, and only get complex when they EGL Rich UI is designed to be extensible from day one. In essence, any technology or library that is written in Java. Script or that has a Java. Script interface can be exposed very easily into EGL Rich UI. Included with the EGL Rich UI offering we provide numerous examples that do just that. Some of those examples are Google Maps, dojo, Silver. Light, 2 D rendering, Flex, etc. Each offer their own specific values and features. 11
