I forgot to say that the cause for the DeadlineExceededException was
log4j, which is unable to log very large strings (xml).
Nevertheless is JAXB in my opinion not the first choice when parsing
large xml files, because of the worse performance.

Hi,
This approach would be my next choice. but implementing and testing
this should be more complex as with JAXB?

Hi,
do you validate your XML with an xsd? Have you done any extra
configuration for JAXB? And do you parse very large XML?
My Code looks like this. It hangs when parsing and validating large
XML files. I think the problem may be, that with JAXB too many classes
are created. Here is my code, which
Hi all,
I need to parse large xml files. My first try was using JAXB. It works
ok for smaller xml files, but when a large xml is parsed, I get an

Furthermore the new JAXB2 jar (JAXB2_20101209.jar) is too large to
I got the same problem since today. Changing the version number did
not change anything. Maybe a Google server problem?
someone had this problem in 2009. So this is possibly not a new
problem...

Hi all,
I read the post
http://groups.google.com/group/google-appengine-java/browse_thread/thread/fbd26de27f77f470
which describes a problem with the local datastore and empty lists.
This problem seems to be fixed. But maybe I have found another one.
I have a list "List favoritesUserId" in a i

Hi all,
I have 4 classes: A, B, C and D:
Class A is the root class.
B is a child of A.
C is a child of B.
D is an embedded class in C.
the classes look like the one at the end of the post.
When I Insert an instance of class A, I get the following exception:
java.lang.IllegalArgumentException: out

Hi all,
I am trying to model a 1:n relationship between different "myAppUser"
instances on Google App Engines Datastore. MyAppUser has a reference
to 0...n other users (friends).
MyAppUser is currently defined as showed below:
class MyAppUser {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorS
