Managing Environment Specific Configuration with Seam
June 17, 2008
Swapping configuration between development and production (and often other environments) is usually a custom solution but often follows a general pattern. Personally, I usually leave this up to properties files. For instance, let’s say we have a specific URL for an adding service and let’s say the URL changes between the development and production [...]

Generating Namespaces and schemas for your Seam components
January 8, 2008
With Seam you have options for component configuration. One of those options is configuration through use of components.xml. This is especially valuable when you have components that are reused among application instances as it allows the configuration to be specific based on the needs of the application. Seam provides a very simple [...]
Contextual injection of core domain concepts with Seam
December 20, 2007
Update: Pete Muir recently posted an alternative to the example described here for the UserProfile object. It avoids potential LazyInitializationException if you access a property which was not initialized inside the loading conversation since the UserProfile is SESSION scoped. I prefer Pete’s approach to the implementation but the concept is the [...]
Setting the conversation-timeout in Seam, why it really does work

At first glance most developers relate [...]
