Re: [appengine-java] Re: Best Java Web Frameworks for GAE (aka speed)
I'm wondering what's the best IoC container with the lowest startup time. Guice? Pico? Spring?

Re: [appengine-java] Trying to use Ehcache 2.0.1 with web module
Hi Jason If you have any news please tell us.

Re: [appengine-java] Re: Problems enabling Second-level cache with JPA
Thanks for the reply. And about citing GAE caveats: maybe that's a good idea to promote your product (I can speak for myself: I never heard about datanucleus before GAE, and it seems like a nice product). About 1.1 support: although there is no more support, the current GAE version + datanucleus-cache-1.1 should have worked? Thanks in advance and congratulations for the product On Tue, May 4, 2010 at 13:32, datanucleus wrote: > And DataNucleus docs for v2.0, v2.1 don't mention GAE/J since GAE/J > doesn't work with them, and we've been given no timescales when it > will. > The DN v1.1 docs mention GAE/J, but we have absolutely no intention of > mentioning caveats to specifications necessary to run GAE/J - since we > see no major reason why the vast majority of JDO3 and JPA2 can't be > handled cleanly with a NoSQL datastore. > > Can't help you with your issue since v1.1 is no longer supported, > except commercially > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine for Java" group. > To post to this group, send email to > google-appengine-j...@googlegroups.com. > To unsubscribe from this group, send email to > google-appengine-java+unsubscr...@googlegroups.com > . > For more options, visit this group at > http://groups.google.com/group/google-appengine-java?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
