I absolutely have no idea what cross-compiling means. I've been
working with Java for 10+ years, and I've never heard of it.
I've never had to do an rich-internet-application ever, and I've never
used GWT. I have written Struts1, Struts, and Spring1 applications,
so I've had to work with MVC for a long time which used to be the
"thing" to do.
The application does use Hibernate and Spring, and a good part of this
web-application uses behind the scenes Spring server-side code.
I got handed the UI part which does use SmartGWT, my co-workers and I
have successfully worked on getting code from the database to the
SmartGWT UI.
Since we are not paying thousands of dollars for the SmartGWT Server,
we are writing it ourselves ... using GWT-RPC.
Although I can already get data from the database to the UI ... it's
going back that I need to work on.
I just thought getting data wih GWT-RPC would get the pipe-line
working between the two.
There have been integrations with GWT/Spring from what I have seen, so
I will keep looking and working on this.
Thanks!
