Portlet Factory, Version 6.1.2
Developing Web applications
Once you create a project and models, you are ready to start adding builders to your models.
Most well-designed Web applications implement the Service-Oriented Architecture (SOA). In an SOA application, you create models that either call backend services or present a user interface for invoking services. Developing Web applications topics introduce you to creating pages and forms for the user interface or creating the services for calling backend systems.
Parent topic: Working with WebSphere Portlet Factory
- Overview: creating pages and forms
The pages and forms in your application provide for the viewing of data and the interaction between the user and the application logic and data.
- Overview: working with data services
IBM® WebSphere Portlet Factory Service-Oriented Architecture (SOA) defines Service Provider Models that access backend data and services and Service Consumer or Presentation Models that provide the frontend web user interface.
- Overview: web services
IBM WebSphere Portlet Factory Designer allows you to call a web service.
- Working with a database
IBM WebSphere Portlet Factory provides a variety of database tools from high-level to low-level.
- Overview: working with Java
IBM WebSphere Portlet Factory applications rely on Java for all their application logic.
- Overview: handling events
Your model can use events to trap and process different types of events.
- Advanced error handling techniques
If the method calls within the Java-based method have an error handler, the lower-level handler, which is the handler in the method calls that are contained in the Java-based method, is called.
- Overview: working with XML
When you develop J2EE applications with IBM WebSphere Portlet Factory, much of the underlying technology relies on XML.
- Overview: communicating between models
If your IBM WebSphere Portlet Factory application utilizes more than one model for its functionality, you may need to send data from one model to another.
- Overview: localizing applications
You can set up applications built with IBM WebSphere Portlet Factory to run with different local languages.
- Learning about WebSphere Portlet Factory
- The data service models
To implement an SOA application, create models that are either Service Providers (back-end data access) or Service Consumers (front-end presentation) and then combine them (flexibly) both for application testing and for deployment.
- Developing portlets with IBM WebSphere Portlet Factory
During the course of development, you will use the WebSphere Portlet Factory Designer to create the portlet functionality and run WebSphere Portlet Factory's deployment scripts to create a WAR file that contains the portlets you created.
- Developing widgets with IBM WebSphere Portlet Factory
During the course of development, you use the WebSphere Portlet Factory Designer to create and run widgets locally. The following steps assume that you have a locally-installed IBM Lotus® Mashups server. This is the recommended practice for rapid development of widgets. If you do not have a local mashup server, refer to Deployment for Production (see below) for information about how to generate a production WAR to deploy widgets to a remote mashup server using the IBM InfoSphere MashupHub.
