We've started using side-by-side deployment of our WAR file. Sometimes it works perfectly, but sometimes it suffers from the same cache issues as a normal deployment and we have to stop the servers to clear the cache.
The only gotcha I've seen related to application-scoped v global-scoped resources.
Does anyone know of any reason why side-by-side deployments may fail sometimes as at present this is preventing us from trusting this technology in production.
Are there any coding standards that we may have missed?
Thanks in advance.
