Hacking just for Fun: Raid5 in Java
Hacking . Java . SnippetsI was just curious how easy it might be to write a RAID5 compatible Outputstream in Java? Just a few Lines. For sure it is not the most elegante solution.

Dies ist recht gut unter Deployment options in der Play!-Dokumentation recht gut erklärt. Was hier allerdings verschwiegen wird ist, wie man den notwendigen Context beim Routing konfiguriert. (Der Context ist der Pfad der Anwendung, welcher standardmäßig vom
