I have used code generators in the past. True they can save initial development time, but many have serious short comings. (Not that this one does as I know nothing about it, but in general.)
1. The code is lowest common denominator code. Meaning that the generated code could typlically be optimized for the specific situation that it is generated for.
2. Depending on the programatic structure of the generator, the code can be very difficult to read for future maintenance.
3. Management often mistakes having a code generator can replace experianced programers and save big $$$. What usually happens is that the more the company invests in generated code, the less the developers know, the poorer the application design, the more you need experianced programmer to tell you why you are having performance problems. (The same argument can be made for intellegent IDE's which is really all a code generator is).
4. The generator itself can outdate itself very quickly, locking you into old technologies. For example, this email indicated struts 1.2, which version? 1.2.3, 1.2.7? Also, is this for java 1.5, 1.4, 1.3? Companies the size of IBM, Borland, Sun or open source sites like Jakarta have the resources to keep their software/frameworks up to date with technology, startup companys or school projects don't have that luxury.
So, where I like the Idea of a generator for speed, I have difficulty accepting the cost.

Jinpeng-
I think code generators could be a 'good thing' ..A few questions -
Does it create Tags?
Tag Library Descriptor files?
Does it generate desciptor files (struts-config.xml?)?
Does it generate entity beans?
session beans?
Does it war the file afterwards?
Does it cold deploy /hot deploy to Tomcat ?
If so which version?
???
