[appengine-java] Using external jars
Hi I'm using eclipse with gwt and App Engine. I'm trying to build a servlet that sends out data encoded in JSON format. For that I'm trying to use the flexjson external library for JSON serializing (is there anything better already within gwt/ appengine?) - which causes a java.lang.NoClassDefFoundError exception. I Was under the impression that on the server side I can use any external jars without further settings. What did I get wrong?

Hi,
First of all, thanks for posting, it really helps me.
objectuser : Good post and the link was really nice.
Albert Attard : Thanks for the examples, it shows that you have to
wright lots of code to manage your own relationships (which I was
trying to avoid).
leszek: This is what I did and I was trying to avoid to handle
persistence issues as much as I could.
I will re-model and start over and see how I should go on.
Thanks.

[appengine-java] Re: Log4J vs. java.util.logging in App Engine projects
Thanks much for the response Rajeev. Let me see if I can repeat and reduce it to make sure I understand the formula. 1) DataNucleus will use EITHER log4j OR java.util.logging. It never uses both. 2) DataNucleus will use log4j if it detects log4j classes on the classpath, otherwise it will use java.util.logging 3) If my app doesn't use log4j, then I can safely delete the default log4j.properties file and DataNucleus will happily use java.util.logging Is this correct? On Aug 31, 5:22 pm, Rajeev Dayal rda...@google.com wrote: +[tobyr] Hi Bill, We include both logging files due to the implementation of Datanucleus. If you have log4j on your classpath (or if you have any jars which bundle the log4j classes), then Datanucleus will use the log4j logging system. If you don't have a configuration file for log4j, then none of the information will be displayed. That is why we include one by default. If you do not have log4j on your classpath, then the log4j system is not used, and neither is the log4j.properties file which we include. If you are sure that you do not have any log4j classes on your classpath, then you can safely remove the log4j.properties file, and control all of your logging via the logging.properties file. If you're using log4j, you can get rid of the logging.properties file. My recommendation would be to keep both files, and only update the one for the logging system that you're using. You don't need to keep both of them in sync unless you adjust the Datanucleus logging levels. Let me know if you have any questions - I know that this is somewhat confusing.

If I make changes to one should I make changes to another? Is there a safe way to delete one and simply use the other? If so which one is the keeper?

If you have log4j on your classpath (or if you have any jars which bundle the log4j classes), then Datanucleus will use the log4j logging system. If you don't have a configuration file for log4j, then none of the information will be displayed. That is why we include one by default. If you do not have log4j on your classpath, then the log4j system is not used, and neither is the log4j.properties file which we include. If you are sure that you do not have any log4j classes on your classpath, then you can safely remove the log4j.properties file, and control all of your logging via the logging.properties file. If you're using log4j, you can get rid of the logging.properties file. My recommendation would be to keep both files, and only update the one for the logging system that you're using. You don't need to keep both of them in sync unless you adjust the Datanucleus logging levels. Let me know if you have any questions - I know that this is somewhat confusing.

[appengine-java] Inconsistence between how app-engine sorts string encoded-keys and java method String.compareTo()
Hello!
I ran over this problem. I was retrieving a DbContact data set
simply ordered by
encodedKey ascending, and i got this list:
[(key agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYm0gMCxIJRGJDb250YWN0GJxIDA
name EUROTRIM)
, (key agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYnUgMCxIJRGJDb250YWN0GJ5IDA
name ANCA ELECTRIC SYSTEMS)
, (key agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYn0gMCxIJRGJDb250YWN0GKBIDA
name TWIN TRADING)
...
So, apparently
agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYnUgMCxIJRGJDb250YWN0GJ5IDA
agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYn0gMCxIJRGJDb250YWN0GKBIDA (the
second and the third entries in the above list)
But
agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYnUgMCxIJRGJDb250YWN0GJ5IDA.compareTo
(agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYn0gMCxIJRGJDb250YWN0GKBIDA) =
37 0, which is opposite!
The encodedKey field is defined in the DbContact class as:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class DbContact extends DbEntity {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName=datanucleus, key=gae.encoded-pk,
value=true)
private String encodedKey;
@Persistent
private DbCustomer customer;
...
Also, i have a DbCustomer class which is the parent of a DbContact
class, defined as:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class DbCustomer extends DbEntity {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName=datanucleus, key=gae.encoded-
pk,value=true)
private String encodedKey;
@Persistent(mappedBy = customer)
@Order(extensions = @Extension(vendorName=datanucleus,
key=list-ordering, value=customerProfile desc))
private ListDbContact contacts;
..
So what's with this inconsistence? Have any ideas?

Hi David.

[appengine-java] Re: issues with compass for GAE apps
Vik, Do you have some sample code to reproduce this? By default, we throw an exception if you try to create more than one PersistenceManagerFactory. Are you using a singleton class to prevent more than one from being created? If so, are you maybe loading that singleton class in different classloaders? (Try logging the classloader object reference that tries to create the PersistenceManagerFactory). Lastly, you can disable the exception if you want (details should be in the exception message), but it will be a performance problem for you if you're creating more than a few PersistenceManagerFactory's.

[appengine-java] Re: test unit doesn't work more
I also had this issue using the Eclipse plug-in.
This does not appear to be the original issue (http://code.google.com/
p/googleappengine/issues/detail?id=1876)
I think the documentation is correct. I think it's the Eclipse plug-in
that has the this new issue.
It appears that the Eclipse plug-in does not add appengine-api-
stubs.jar and appengine-local-runtime.jar to your class path (which
the JUnit documentation mentions
http://code.google.com/appengine/docs/java/howto/unittesting.html).
These jars are distributed with the Eclipse 1.2.2-200907291526 plug-in
in the lib/impl directory. So to work around this issue I made an
eclipse user library with these two jars in and added it to my class
path.
This has solved my local issues.
I've not tried uploading this to GAE yet, nor checked for any
overlapping classpath issues with sealed jars etc.

Hi everyone, let's see if we can get this ironed out.
First off, the ApiProxy.Environment interface did change in 1.2.2. There is
one new method (getAttributes()), and the existing methods now need to
return meaningful values in your tests. If you're following the how-to
article on unit testing
(http://code.google.com/appengine/docs/java/howto/unittesting.html) you'll
need to update your TestEnvironment class to look like this
one:http://code.google.com/p/datanucleus-appengine/source/browse/branches...

We're working on getting the docs updated right now.
If your TestEnvironment class looks exactly like this and your unit tests
are still failing, please post a complete example including model classes
and test code and I'll investigate.

[appengine-java] memcache service down?
Hi all, I saw that most of my cron jobs which are using calls to memcache are down, is this a known issue?

[appengine-java] Re: memcache service down?
Adding to that: I just saw the new version live for one 'request' - I then thought it all works and changed the main version to the new version. Upon testing groovytweets.org it did not work any more... so I switched back but now the OLD version is also down... ? Soo There must be something strange going on here I hope.
