Hi, My typical application development is the presentation layer, php, mostly does one to two calls to application server using xmlrpc/soap. Comparing this to Seam/JSF style of very tight integration between presentation and business logic by using backing bean, my current style of presentation layer seems to be more efficient (apart from soap overhead). So my 2 similar questions: 1. Is Seam/JSF only good when JSF and the backing beans are in the same JVM? 2. Seam provides very tight integration between JSF and business logic, does it mean Seam is promoting the unification of presentation and business layer into a single environment (jvm)? Thanks.
