classloader - ClassCastException by cast to owe type -


in implementation of org.dozer.beanfactory.createbean(object, class<?>, string) try cast object type of it. if deploy bundles, shut down , start bundles got classcastexception: 

java.lang.classcastexception: de.xxx.configuration cannot cast de.xxx.configuration

i suspect problem classloaders of karaf and/or dozer. class 1 time exists in jars , isn't modified. configuration doesn't implement serializeable , has no serial version id.

how avoid exception?

kind regards

if have exception someclass can not cast someclass signal these 2 classes have different classloaders. means loaded 2 different classloaders. example if have bundle , b, both contains someclass, each class different , object of class loaded bundle can not cast type loaded bundle b.

since pointing have class in 1 jar recommend check if have no entries in lib/ directory (dozer can load through sun.misc.appclassloader). put breakpoint in dozer beanfactory , inspect object instance class , class object passed createbean method. should bundle class loaders used. since fixing issue easier.

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...
