Hello All,
I am running my web application on the GAE/J 1.3.8 development server
on my local machine. I have just got the following log entry whilst
testing:
21-Oct-2010 09:13:06 com.google.apphosting.utils.jetty.JettyLogger
warn
WARNING: fa...@null line:1 col:1 : org.xml.sax.SAXParseExceptio
Same issue for the past 3 days.
Only occuring on the dev server.
I have tried for hours to solve it. No clue...
Fortunately, no impact on the production environment.

Hi
I have a strange problem. Eclipse cannot clean and build my Google App
Engine project. It says:

I think you're confusing entity *group* with actual entities stored in
datastore, as I doubt you'll have thousands of related entities.

Channel API was defined in 1.3.4, before it was even announced :-)

1 info that is important to reach the value for this max number (if

Yes, but you will have to dig a bit: in the source:

Schemaless entities are how datastore models are saved underneath the hood.

I have a CSS file main.css in my war directory. I've modified it, but
the trouble is that when I execute my project in Eclipse as a

I searched in the workspace, and even in my hole homedir,
I've reproduced this. I'm following up. What is it you need this class for?
You can't do host resolution yet, even in the dev app server. The extent of
what you can do is this:
InetAddress address = InetAddress.getLocalHost();
resp.getWriter().println("Address: " + address.getHostAddress()
And I thought that I had gotten to the finish line without ever
needing the low-level API, guess I was wrong =). Thanks for the hint

One more thing - your example is actually a perfect illustration of

What does the query look like? Query performance can sometimes be affected
by the "shape" of the data - that is, if the data changes, it may change the
number of indexes we need to zig-zag over.

First of all, i realized that part of the problem was the range of the
query (my data objects/entities grew very fast so i didn't that i was

from moment to mom
Since you are getting
javax.jdo.JDOFatalUserException: Object Manager has been closed
I presume that you might be using the same pm instance after you have
closed it. After your
pm.close();
your first time, did you obtain a new pm before your second time?

Of course, you can only add entities to your entity group at a certain
rate of transactions per unit time. This is a constraint on how the
number of entities in any given entity group increases over time.
So it looks like this will work if you add this to your appengine-web.xml:
false
Depending on how much you need it, you can enable it today by adding this -
but you lose Java precompilation, so there may be some impact on your cold
startup times.

Thanks for the update, changing precompilation from true to false did
indeed solve the problem.
Is this considered a fix or a temporary work-around? I'm not sure if
the new functionality I've added warrants removing precompilation.
Oh and I need InetAddress as I'm using the Java API from MaxMind
This is a temporary workaround only. We should have this fixed in a few hours.

Hi Erik,
To check (and then limit) the format, you can extract the picture from
the mail as a byte[] and then use this byte[] to create an image via
ImagesService.makeImage(byte[]) and then do Image.getFormat() to see
if you accept the format or not.

Hi,
I think the issue is when you store the image not when you retrieve
it:the published code doesn't show how you store the image.
