new xml tags <beans:bean > etc - Im confused

[emmettwalsh]

Hi ,

I generated a Spring MVC web app from STS.

I see that the xml files use a whole bunch of new tags i.e. <beans:bean .. etc


Do I have to use these? can I mix with old ones ? whats the advantages? I just got the latest Spring in Action and theres no mention of these new xml namespaces

see below

hope you can help
thanks

I suggest a read on xml namespaces... There are no new namespace which namespace is the root depends on how you configure your xml and xml namespace. For your xml the mvc namespace is the root, thus for all other namespaces you have to prefix them including the beans one.
