[appengine-java] add a new INT-type @Persistent to a existing talbe
my demo
fist，
public class CommentTheme {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private String theme;
}
then
for (int i = 20; i > 0; i--) {
CommentTheme commentTheme = new CommentTheme(i+"")
persistenceManager.makePersistent(commentTheme);
}
now all is OK,but when I add
@Persistent
private int themeCount;
to the class CommentTheme ,the system tell me the themeCount should
not be null,but
if i add
@Persistent
private String themeCount;
all thing is OK
so What is the problem! even if i add a default value to the nt
themeCount ,my app is also Wrong ! WHy

[appengine-java] About LocalDatastoreServiceTestConfig
the docs: Config for accessing the local datastore service in tests. Default behavior is to configure thelocal datastore to only store data in-memory and not write anything to disk. tearDown() wipes out all in-memory state so that the datastore is empty at the end of every test. yes,but i want the datastore IS NOT empty at the end of every test. so I code: LocalDatastoreServiceTestConfig serviceTestConfig =newLocalDatastoreServiceTestConfig(); serviceTestConfig.setNoStorage(false); serviceTestConfig.setNoIndexAutoGen(false); and When I test " pm.makePersistent(ob);" the local_db.bin appear! but there being no data in it, for I code: pm.newQuery(Ob.class).execute(); the size of the List is 0. and then I add "serviceTestConfig.setStoreDelayMs(1);" and then ervey time I makePersistent(ob),there will being data in my local_db.bin ,for i can query it!! So I want to know Why will this happen, or I think the docs should 'alert' it! -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Cannot to read the file under /WEB-INF/classes/
I want to read the config.xml in my webRoot /WEB-INF/classes/
config.xml.
All is OK in localhost.
but when deploying to GAE, it cannot find the xml：
/base/data/home/apps/mainloveplay/4.35187093106408/base/data/home/
apps/mainloveplay/4.35187093106408/WEB-INF/classes/config.xml (No
such file or directory)
the code to get path is：
String rootPath =
ConfigRepository.class.getResource("/").getPath().substring(1);
Document document = reader.read(new File(rootPath + "config.xml"));
so how can I get my config.xml
