java ee - Maven multi-modules by features but sharing webapp -


i'm building multi-modules j2ee web application maven. web business application contains several sub-systems / modules. high modularity, easy-for-distributed-team-development, easy code navigation, easy deployment , upgrading, seperates web business application system features, , layer. here's maven hierarchy:

|--business-sub-system-1 |    --domain |       --pom.xml |    --dao |       --pom.xml |    --service |       --pom.xml |    --webapp(presentation) |       --pom.xml |--pom.xml | |--business-sub-system-2 |    --domain |       --pom.xml |    --dao |       --pom.xml |    --service |       --pom.xml |    --webapp(presentation) |       --pom.xml |--pom.xml | |--business-sub-system-3 | ... |--business-sub-system-4 |... |--business-sub-system-5 |... |... |pom.xml

but have share webapp because whole project treated 1 web project ( 1 web.xml).

enter image description here

my question how seperate webapp different modules can run 1 website? (each business sub-system has individual webapp/html/jsp/js/css, can merge 1 website @ runtime)

thinking this, best advice have is: deploy separately separate team builds. if these sub-systems need independent each other, , can released independently makes no sense @ deploy them @ once.

if not possible because of requirements of system, best solution in terms of architecture combine front-end layer in 1 war component, dependent on different business-sub-systems (domain, dao , service). teams need share component can separate work across e.g. different folders or packages.

having said this, life in consulting not easy logical solutions possible that. here more down-to-earth answer:

in main pom file, use assembly-plugin create layover war of projects. reduce complexity of assembly, can include domain, dao, , service poms simple dependencies.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
