The content display language in WebSphere Portal V4 and V5 is driven by either user language preference or the location of the system. WebSphere Portal does not allow you to change your language preference during an active session. This article describes how to implement the logic to support dynamic language in WebSphere Portal with one click. The major benefit is that the user's preferred language is not changed in the profile. Once the user session expires and the user re-logins into WebSphere Portal, it renders the content based on the user's profile language.

WebSphere portlet filter technology provides a quick solution for adapting and customizing existing portlets so that they may be used in new or different portal applications. A portlet filter is a Java module that can be dynamically plugged into one or more existing portlets to modify portlet request and response, as well as to add new functions to the existing portlets without requiring changes to them. This article describes WebSphere portlet filter basics, its differences from a servlet filter, and how to develop and use a portlet filter to adapt and customize existing portlets.

With all of the magic that goes on in the WebSphere Portal Web interface, it's easy to forget that at its heart, a portlet application is just a collection of servlets and their supporting classes, strung together using the web.xml and portlet.xml files. As we moved to customize the MetroSphere.com experience, we realized that understanding just how these two files fit together was crucial to controlling items such as the initial title of a portlet window. This article explains the major pieces of these two files and how they control what you see in your portlet application.
