Portlet Factory, Version 6.1.2
JavaServer pages guidelines
You can incorporate JavaServer Pages (JSPs) into your models using the following builders:
- JSP Directive
- Adds JSP directives to a page in the model.
- JSP Proxy Page
- Routes requests to an existing JSP page to an action in the model, allowing you to insert model functionality into an existing JSP application.
- JSP Tag
- Allows you to use a JSP Tag library within a page in the model.
In addition to these JSP-specific builders, you can also hand code JSP or use existing JSP in any IBM® WebSphere Portlet Factory pages (Imported Page builder, Page builder, Imported Directory builder, and so on), as long as they do not perform the following actions:
- Forwarding
- Setting response headers
WebSphere Portlet Factory pages are always invoked using include, disallowing these actions.
The Imported Directory builder can often work quite well for bringing in a set of existing JSPs, including inter-page actions/links, provided that they adhere to the caveats above.

- Processing redirections
If any of the JSP pages that you import for use in a model contain any redirection code, you will need to re-implement this behavior with a method in your model.
- Pre-compiling model JSPs
Pre-generating and pre-compiling Java Server Pages (JSPs) prior to deployment eliminates the delay a user experiences due to the lag time caused by waiting for JSP pages to generate and compile.
