I also did some experiments trying to improve my app initial load time
and think simply loading new classes in GAE is quite expensive -
probably due to all the security restrictions of the class loader. It
may be that the first use of a JSP causes a lot of classes to be
loaded which causes the init
Hi,
I think that this extra time you're seeing is the time expended in
compiling the JSP, which occurs the first time a particular JSP is accessed,
as you can see in: http://en.wikipedia.org/wiki/JavaServer_Pages_compiler
You can google around for some precompilation techniques for your JSP
My advice stands though. No jsp means nothing to compile ;)

Hi,
Is there way to concatenate 2 images into one image using

I think google just turned on precompilation in 1.3.1.

From http://code.google.com/appengine/kb/java.html#initfailed it seams
that JSP should also be precompiled, but sometimes it doesn't.

Yea, it seems that according to Eduardo's link the jsps are
precompiled, so it is probably something else.

There are all kinds of random hidden delays when a app isn't used in a
while. One that I think I discovered, is the first time you load an object
of type X from the database, there is a 2000ms lag. At least working this
way in my app. Can be very active using object A from the data store, but

I have a Java-app-with-authentication. I created it this way. I wish I
had not.
I need to upload bulk data. I am waiting for months but Java "still"
cannot do it.
I tried to do it with Python. I cannot do with it either because I
have created my app with authentication and I cannot change my app

My application uses JPA and I see the same errors as in version 1.3.0
now.
If I count records in a table which has more than 1000 entries, the
result is 1000.
If I try to start a Query at an offset > 1000, this error occurs:
Caused by: java.lang.IllegalArgumentException: offset may not be above
I'm having the same problem, specifically using verizon.
I can send text messages to vtext.com, but cannot send images to
vzwpix.com.
I set up a forward from a different email address, to my phone
(@vzwpix.com), and it worked without problems.

Yes, that database lag you talk about is JDO setting up the metadata
for objects. If you go into your logging.properties and change the
logging level to FINE, you can see what it is doing.

All of this would not be an issue if users didn't have to actually
wait for the initialization of everything. If Google would implement
this warm-up request feature
http://code.google.com/p/googleappengine/issues/detail?id=2690
then we wouldn't have to worry about slowness due to initialization.
Offset get all records from datastore, than skip first n records.
You can try to read http://code.google.com/appengine/articles/paging.html

Ok, Thanks, Ikai. I will try this (subject to latency considerations),
and let you know.
I am assuming GAE tracks the bytes flowing on the wire and log it -
could there be access to such data from the logs for each request? If
so, how to enable such logging and how to access such data from the
log
Thanks Ikai,
I am doing it the way you described and it does work. Just wanted to know if
there is a way to set the child key explicitly as parent + "const string".
But I understood that will not work with datastore generated keys since the
parent needs to be persisted in order to get a key. Apolog
