Long long ago, I had written an article in Computers Today about WAP. It was in November 2000 issue. What I had written then about server side delivery will be preferred way is still true.
Ericsson has released an open source JSF renderer for mobiles! get the presentation here.
You can also download the source from their site.
The advantage of using Java EE to deliver application to mobile is that you don't have to support multiple versions for each vendor and even intra vendor's platform. And unlike Nokia's SDK, which is too fat, Ericson has a small footprint and thus does not lock the developer in.
Recently Sun and Ericsson are collaborating to marry Java technologies with telecommunications. Not that Java was not present in the telecom space, it had JAIN (Java Advanced Intelligent Network) But then there was Parlay led by Microsoft. Now Sun and Ericson have collaborated to produce Parlay interop with Java EE. It too is open source.
To avoid confusion here, I must add that I am talking two different things here. The enterprise applications connect B2C where as AIN (Advanced Intellegent Network) application are more of telecom domain applications like delivering caller tunes of your choice or call divert or voice mail service. Thus you could think it as O2C (Operator to Customer) applications. The only common thread here is the use of Java EE technology.
