java - Designing an app to be deployed with AND without Google App Engine -


after finish developing app using google app engine, how easy distribute if ever need without app engine? thing i've thought of gae has proprietary api using datastore. so, if need deliver app .war file (for example) not deployed app engine, need first refactor code getting/storing data, before building .war, right?

i don't know standard way deliver finished web app product - i've ever used gae, i'm starting project requirements final deliverables unsure @ time.

so i'm wondering, if develop gae, how easy convert?

also, there can or consider while writing gae optimize project whatever packaging options may have in end?

so long app not have elements dependent of google app engines should able deploy anywhere long location can support tomcat or glassfish server. requires manually install server must read on that. there lots of youtubes on subject try break down issue lowest steps possible.

i suggest using framework spring , hibernate lessen headaches. take while understand worth headache if want programming rest of life.
