Composite Application Background A role based application framework where decoupled componentscan communicate through declarative connections (wires) Primarily used to integrate heterogeneous technologies Lotus Notes to SWT, Web to Lotus Notes, SWT to ..., etc Target audience for application assembly is technically savvy linesof business users Was great on paper :) Provide a clear and consistent component model where allcomponents can communicate with well defined properties(outputs) and actions (inputs) The primary value add is using existing resources (applications) innew context and sharing data from those applications with eachother 5. Introduction to Containers Why a new component type? WSDL is very hard to understand Current component model does not work well for complexcontainers:Applications like web applications with more than one page or formHost based applications with many screensSpreadsheets with more than one sheet Creating new components is cumbersomeMust create new Java code, new WSDL, deploy feature and plugin 6. What is really wanted/needed The ability to define new components with no programming and noWSDL Have new components created from basic XML ie. extension points These new components need to be 100% compatible with existingcomponents Let low level assemblers create new components using plugin.xml Let higher level assemblers create new components with CAE. 7. What is a container? A container is a new type of view part that can display not only anapplication but applications with many pages (states) and pieces toit. For instance, we have a web browser container that exposed generalactions and properties. Setting the URL Setting the HTML text Publishing the URL Etc. These containers can define properties and actions at differentlandmarks within the contained content. For instance, define actions and properties across many pages in a webapplication 8.

What is a landmark and a landmark identifier? The term landmark is taken from navigation. Think of what landmarks you know that tell where you are at For instance The statue of Liberty tells you are in New York City The landmarks here are the same concept They tell the container it is in a particular place in the containingapplication. 10. What is a landmark and a landmark identifier?(cont) A container definition states what its landmark identifier is. The landmark identifier tells the container what reference to use to identifydifferent states (or places) of the component. These states can then have actions applied to them by referencing the valuereturned from the container using the landmark identifier the returnedvalue is the landmark. The landmark is the value returned by the container using thelandmark identifier All landmark values are basic strings Regular expressions and wild-cards are also supported http://www.ibm.com/* 11.

Property Name spaces for common containers The new framework introduces the concept of shared property spaces This enables multiple instances of a container type to share the valuesacross them You can optionally set the namespace for a specific component using theadvanced property - com.ibm.rcp.composite.container.namespace This name space will be used to store the and retrieve the property for the specificcomponent. By default the name space is the perspective ID, so all same types of componentsshare properties on a given screen 13.

Container Tooling Generic Landmark Editor provider by Composite Application Editor Define landmarks & operations Landmark, operation, and field suggestions provided by container 15. Container Tooling Import / Export landmark definitionsExports the extension xml for the landmarks Automatically populated with pre-defined landmarks & operations from plugin.xmlConfigure and distribute a container with some baselandmarksApplication assemblers can extend this e.g. For differentregions 16.

The Browser Container Included in Lotus Expeditor 6.2 & Lotus Notes 8.5 Easy component creation for complex web browser applications For instance: We have a web application where there are many pages and in those pagesare different forms that can be filled out.Page 1Page 2Page 3Expense FormTravel FormRequisition Form Each form is on a different page within the overall web application Lets say each form has a Name field on each page. We want to expose that Name field to be set from other components 18. The Browser Container There is a problem though: On Page 1 the field Name has the HTML name attribute set to nameField On Page 2 the field Name has the HTML name attribute set to Requester And on Page 3, it is not even a field, it is highlighted text in bold What we want to do is expose Name as a field that can be set by orqueried by other components (publish or receive) We can handle this by specifying the landmark identifier as the URLor the Title of the page This makes the landmark results unique so we can define how Name ishandled on the three different pages. 19.

The Notes Containers Web Delivery Notes View Container & PIM View Container Extract data from Notes views as properties, right in CAENO WSDL!No database modifications Each property is published individually upon selection Multiple selections are delimited. 00 by defaultDelimiter can be overridden Hide the complexity of Landmarks and the underlying configuration 24. The Notes Containers Notes View Container Based on the re-parent technology Can contain any Notes View Formula is supported to extract information from view Uses Java back-end classes to access the data. Document is opened. 25.

The Notes Containers PIM View Container Based on Notes Java views (CSI Views) Supports both Formula and Columns to extract data Formula uses Java back-end classes document is opened Columns use new Java view framework document not opened, data exists Supports 5 default configurations Inbox, Calendar, Contacts, Todo, Recent Collaborations 27.

Agenda Introduction to Containers Landmarks 101 Container Tooling The Browser Container The Notes Containers The Symphony Spreadsheet Container Building your own containers What's next? Q&A 35. Building your own containers You can build your own container using our new container API's Your container would extend our base abstract class com.ibm.rcp.composite.container.core.AppContainer The container is initialized in the createPartControl method container = new MyContainer(this); The container can tell the core what events it supports for landmarks: Override getAvailableEvents(), example: public Map getAvailableEvents() { Map map = new HashMap(); map.put("selection", "selection"); return map; } 36. Building your own containers (cont) Even the actions can be completely custom for your container Make them make sense for your container For instance, if you only support a Publish action then you could do this: public Map getSuggestedActions() { Map map = new HashMap(); map.put(AppContainer.PUBLISH, AppContainer.PUBLISH); return map; } 37. Building your own containers (cont) You can publish and receive data easily No Property Broker API's are needed You would implement the following two methods: public void publish(String name, String field, LandmarkEvent event,Object context) public void receive(String name, String field, LandmarkEvent event,Object context) You would then call the core containers publishProperty() method to publishthe data to the broker publishProperty(name, value.toString()); 38. Building your own containers (cont) Each area of the composite application editor can be customized byyour container Components can add their own tabs for editing configuration 39.
