Software Documentation as a Guidebook
Working software over comprehensive documentation" is what the Manifesto for Agile Software Development says and it's incredible to see how many software teams have interpreted those five words as "don't write *any* documentation".
...
Unfortunately the code doesn't tell the whole story and not having a source of supplementary information about a complex software system can slow the team down as they struggle to navigate the codebase.
The Importance of Packages
Packages have several important usages:
- Namespaces - helps avoid collisions
- Organization - help locate classes. Following scheme is proposed: <organisational-prefix>.<application>.<deployment-unit>.<module>.<layer>.<optional further substructure if needed>. For example: com.mycompany.theCoolApp.server.user.persistence
- Intermediate modeling block - represent a bigger-scale abstraction within the application
- Architecture-revealing - helps understand architecture of the app
- Promotes SRP
- Managing Dependencies - for example allows cyclical dependencies between packages using JDepend.

What is the future for GWT?
While GWT is often thought of as an enterprise technology, 65% of the survey respondents are working on projects for use outside of their companies. That said, only 1% of the projects are games - the vast majority are business applications.
...
While the vast majority of the apps (over 98%) target desktop-based users, the number of these apps that also also target tablets (36%) eclipses the 26% of apps that also aim at mobile phones.
The main complaints with GWT are compile time (49%) and the lack of enough good quality UI widgets (34%). The biggest benefit of GWT is not having to deal with browser compatibility issues (60%). Despite the complaints, over 88% of the self selected respondents plan to use GWT on their next project. The report is available online in return for your name and email address.
