[appengine-java] Re: one project access classes in another project in same account
I also noticed that in persistence.xml, the connectionUrl is always set to appengine. I believe this implies the java code can only access the datastore in the same app too? Is there any loop hole to access one of the app's datastore using some jndi url like in tomcat? Bruce On May 7, 4:31 pm, bhomass bhom...@gmail.com wrote: Ok, I had to rethink this whole thing.
