[jdf-dev] Questions about integrating seam-spring for Quickstarts (@Produces ApplicationContext, <cdi:bean-manager/>, and the spring jars)

I had a few questions about seam-spring as related to the quickstart I submitted at https://github.com/StevenBoscarine/spring-seam-helloworld. It is a simplified version of https://github.com/mbogoevici/Seam-Spring-Basic-Example My goal was to illustrate how to use seam-spring and strip the example down to the barest elements so beginners had less opportunity for confusion. The example works great, but I left in some code not fully understanding what it does. I'd love to provide explanations to the users. First question I noticed in Marius' example: https://github.com/mbogoevici/Seam-Spring-Basic-Example/blob/master/src/m... ...that he has a producer-field for ApplicationContext. Is that necessary? @Produces @Web @SpringContext ApplicationContext context; I added one in my application because I noticed it didn't seem to work without it and wanted to add better comments explaining why it was needed. https://github.com/StevenBoscarine/spring-seam-helloworld/blob/master/src... For: https://github.com/StevenBoscarine/spring-seam-helloworld/blob/master/src... What does the line below do?: <!-- FIXME: What does this do? --> <cdi:bean-manager /> Is spring-web needed? What does it do? <!-- Is this needed? --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>3.1.1.RELEASE</version> </dependency> Where can I find info on what the different Spring jars do? I'd really love to explain to the user in a sentence or 2 why there's a spring-core and a spring-context and what each one does. Thanks, Steven
