My app started throwing exceptions right after the latest maintenance;
apparently Runtime.getRuntime().totalMemory() is now actually removed from
the server runtime? Couldn't you just return zero?
java.lang.NoSuchMethodError:

If you are brand-new to coding, I would not use GWT. I would start
with HTML/CSS/Javascript. Many folks start their coding careers there
(and many many stay there because they love it). You can get started
quickly and the learning curve is not so steep. The learning curve on

I have an Java App Engine project using SDK 1.3.5 and the latest
Restlet GAE 2.0rc4 to implement some restful services. Everything
worked well (this has been in product for 6 months) until I added GWT

In my application I'm using JDO. In some cases, I have un-owned
relationships where I explicitly created my own entity group because I
need to be able to do transactions with a group of records. For

happens inside a task handler. Basically, I'm trying to enforce strict
serial handling by the tasks, so I have my task, as the last thing it
does, enqueue another task to the same url (but with a different name,

It turns out the technique I described in my previous post has two issues.
1. Because only one transaction can be running at a time within a process,
and the entity used as the mutex really cannot be in the same entity group
as the primary entity, you can get into a situation where the mutex ent
We are testing a update to our app on a couple of qa instances

I've been using Java AppEngine since it became available. I chose
JDO for portability and so I could get started very quickly. I can
say that JDO offers very little real portability for significant apps
because of the very different semantics of the underlying datastore.
