Best Practices for Creating Portlets with WebSphere Portlet Factory WebSphere Portlet Factory and Software Automation WebSphere Portlet Factory is a system for software automation Portlet Factory’s model-based development paradigm – using Builders – is different than other development tools You specify the inputs that control code generation, instead of manipulating code and application artifacts directly The benefit of this approach is a high degree of automation Techniques and best practices have been evolving over the last several years of experience with this paradigm Best Practices Topics Creating a portlet using a service architecture Controlling and customizing the user interface Choosing the right builder Creating multi-language applications Debugging techniques Performance Top 10 model development best practices Creating a Portlet Using a Service Architecture SOA builders in Portlet Factory make it easy to create separate service provider and consumer layers These builders work in a consistent way with any back end data source Service Provider and Consumer Models Benefits of Using a Service Oriented Architecture Separate back end and presentation development Automatic support for service testing Develop consumer (presentation) model without any back end access, using stub service model Reuse services in multiple presentation models Easily transform data between back end schema and some other schema Switch between multiple implementations of a service interface without changing consumer model. Creating a Portlet Using a Service Architecture Steps for creating a portlet: Create service for data access: Use data access builder (SQL, SAP, Domino, etc.) for back end access Use Service Definition and Service Operation builders to create service Can include multiple operations, data transformation, and custom processing Note that this service can be reused across any number of portlets Use high-level builder to create initial presentation based on service inputs a
