what do you mean by integrate?
For example, in my IDE, IntelliJ IDEA, I have a Seam project that includes the seam jars. The IDE simply recognizes the annotations and auto-imports and auto-completes them for me.
I presume this is true for Eclipse, probably also for Netbeans, etc. provided you import the Seam .jar files into your project and your IDE provides auto-complete features.
Since much of working with Seam amounts to using the annotations, I am not sure what other kinds of integration make sense....
Right, we are pretty much IDE neutral for now.
The kind of IDE support that would be good is:
* wizards for new project, new component, new page, etc
* stuff like being able to click to navigate to code from an EL expression, and refactor Seam component names.
But we're not quite there yet ;-)
