[appengine-java] Re: Data Store Indexes
Also, I updated my datastore-indexes.xml as the following: ?xml version=1.0 encoding=utf-8? datastore-indexes xmlns=http://appengine.google.com/ns/datastore-indexes/1.0; autoGenerate=true datastore-index kind=MDsIri ancestor=false property name=iri direction=asc / property name=name direction=asc / property name=image direction=asc / property name=iriLowerCase direction=asc / property name=nameLowerCase direction=asc / /datastore-index /datastore-indexes I changed the kind from com.col.server.MDsIri to MDsIri. It still produced No results. I cannot test it on Development Server -- please let me know if there is a way to test it locally.. I uploaded it and only tested it on the (deployed) App Engine.

[appengine-java] AccessControlException on DatastoreService.put() method
I got the AccessControlException on the following code snippet:
public void add(ListString iriList, ListString nameList,
ListString imageList) {
// deleted for brevity
try {
datastore.put(eList); // The log
below shows this line as at
com.col.server.MDsIri.add(MDsIri.java:74)
} catch (IllegalArgumentException exIA) {
logger.severe(IllegalArgumentException when trying to
datastore.put. Exception message: + exIA.getMessage());
} catch (ConcurrentModificationException

logger.severe(ConcurrentModificationException when trying to

logger.severe(Exception when trying
to datastore.put. Exception
message: + ex.getMessage()); // the log (last line) below says that
the message is unknown
}
}
// deleted for brevity
}
I follow the guideline that the eList has only 500 entities at most as
mentioned on
http://code.google.com/appengine/docs/java/datastore/overview.html#Quotas_and_Limits.
Also, I don't call any thread or system threads as mentioned on
http://code.google.com/appengine/docs/java/runtime.html#The_Sandbox.
I did not get the error below on my Development Server.
I don't know how to interpret the error because the exception/error
message is Unknown(last line of the log).
I appreciate any help.

[appengine-java] DatastoreService.put behaves differently in development server and deployed env
I can store a few thousands of entities incrementally in Development
Server environment using the method below.
public void add(ListString iriList, ListString nameList,
ListString imageList) {
int counter = 0;
ArrayListEntity eList = new ArrayListEntity();
for (int index=0; indexiriList.size(); index++) {
Entity e = createEntity(iriList.get(index),
nameList.get(index),
imageList.get(index)); // e should be less than 1,000 bytes each
eList.add(e);
counter++; // Break down the storing to DS_LIMIT each
due to
Google limitation/quotas
if ((counter % CUtility.DS_LIMIT) == 0) { // DS_LIMIT
= 200
logger.info(Storing +
Integer.toString(counter) + IRIs.);
datastore.put(eList); // Store in
batch
eList = new ArrayListEntity();//
Reset the array
} // if
} // for
if (eList.size() 0)
datastore.put(eList); // Store in batch
logger.info(Storing + Integer.toString(counter) + IRIs.);
}
But when using it in deployed environment, it can only store 1,000
entities. It never adds beyond it. It does not hit the 30-second
limitation because I call it incrementally. After having 1,000
entities, I tried to add more. Below is the log from the deployed
server and verified it stored additional 225 entities without throwing
any exception.
I 10-30 11:38AM 02.852 com.col.server.tool.DsWriter writeIri: Writing
225 to MDsIri
I 10-30 11:38AM 02.867 com.col.server.MDsIri add: Storing 200 IRIs.
I 10-30 11:38AM 04.551 com.col.server.MDsIri add: Storing 225 IRIs.
I 10-30 11:38AM 04.551 com.col.server.tool.DsWriter writeIri:
Done
Do I have to do something differently in deployed environment? Any
configuration changes or something? What did I do wrong? I know some
people have stored millions of entities successfully.
Thanks in advance for your help.

[appengine-java] Re: PreparedQuery.countEntities() clarifications
Thanks Yasuo. It's definitely very helpful. I am just reading
http://code.google.com/appengine/docs/java/datastore/stats.html.
Your example clarifies a few things which is unclear on the doc.
It works now!
With my original code ... On the Development server, it returns
whatever the number of the entities. On the (deployed) App Engine
always returns 1000 due to the limitation as shown on
http://code.google.com/appengine/docs/java/datastore/overview.html#Quotas_and_Limits
I have changed my code as the following (using your example)
protected int count(String kind) {
Query query = new Query(__Stat_Kind__);
query.addFilter(kind_name, FilterOperator.EQUAL,
kind);
PreparedQuery preparedQuery = datastore.prepare
(query);
Entity statKind = preparedQuery.asSingleEntity(); //
It works on (deployed App Engine). It returns null on Development
server.
Long totalEntities = (Long) statKind.getProperty
(count);
int result = totalEntities.intValue();
return result;
}
BUT this new code only works on the (deployed) App Engine.
On the Development server, the statKind is null. How do I make it work
on the Development Server?
My environments: GAE 1.2.6, GWT 1.7.1, Eclipse(Galileo), Windows Vista
(32-bit).
Again, thanks.

If your query has no filter condition, I recommend the following query:
DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
Query query = new Query(__Stat_Kind__);
query.addFilter(kind_name, FilterOperator.EQUAL, kind);
Entity stat = ds.prepare(query).asSingleEntity();
Long count = (Long) stat.getProperty(count);
If your query has some filter conditions, I recommend the following query:
DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
Query query = new Query(kind);
query.setKeysOnly();
query.addFilter(...);
int count =
ds.prepare(query).asList(FetchOptions.Builder.withOffset(0)).size();
The first query is faster than the second one.
Hope this helps,

I need to look at the code that retrieves the entity why it is saying
that it is only 1,000. I just found out this
dochttp://code.google.com/appengine/docs/java/datastore/stats.html

I can store a few thousands of entities incrementally in Development
Server environment using the method below.
public void add(ListString iriList, ListString nameList,

for (int index=0; indexiriList.size(); index++) {
Entity e = createEntity(iriList.get(index),

eList.add(e);
counter++; // Break down the storing to DS_LIMIT

logger.info(Storing +

datastore.put(eList); // Store in batch
logger.info(Storing + Integer.toString(counter) +
IRIs.);
}
But when using it in deployed environment, it can only store 1,000
entities. It never adds beyond it. It does not hit the 30-second
limitation because I call it incrementally. After having 1,000
entities, I tried to add more. Below is the log from the deployed
server and verified it stored additional 225 entities without throwing
any exception.
I 10-30 11:38AM 02.852 com.col.server.tool.DsWriter writeIri: Writing

I 10-30 11:38AM 04.551 com.col.server.tool.DsWriter writeIri:
Done
Do I have to do something differently in deployed environment? Any
configuration changes or something? What did I do wrong? I know some
people have stored millions of entities successfully.
Thanks in advance for your help.

[appengine-java] Re: Extra log output
Thanks for your reply, Toby.
I am using log4j because I want to be consistent with some existing
modules/classes. I did the following:
import org.apache.log4j.Logger;
I just saw http://logging.apache.org/log4j/1.2/faq.html#duplicate-messages.
log4j call is cumulative/additive. I called the
BasicConfigurator.configure(); methods more than once. Now it is
fixed.
Again, thanks.

ApiProxy gives you access to the dev_appserver's internal interfaces for the
services that Google provides, such as mail, urlfetch, memcache, xmpp,
etc... ApiProxy is entirely unrelated to GWT RemoteServiceServlets, which is
what your code is trying to use it for.
You only need to use our internal dev_appserver interfaces if you
specifically need to do something with the services that isn't supported on
prod via the standard interfaces. For example, in the page you referenced,
the code clears all record of sent messages:
mailService.clearSentMessages();
That capability makes no sense in production, but it is very useful for
testing locally.

o Click on the Eclipse menu bar Help - Software Update - Manage

o There is no DataNucleus plugin installed.
I don't recall explicitly installing DataNucleus plugin unless GAE or
something else installed as part of their installations.
Also, I tried the following:
o Wrote a populate() method to populate my database (from scratch) in
regular environment (not using junit). It worked fine -- the database
was created.
o Called the same populate() method above in junit environment. It did
not create the database.

What are the junit best practices when using both GAE and GWT?

[appengine-java] ApiProxyLocalImpl.getService question [junit]
I have the following server side code:
package com.foo.server;
// code deleted for brevity
/**
* The server side implementation of the RPC service.
*/
@SuppressWarnings(serial)
public class FooServiceImpl extends RemoteServiceServlet implements
FooService {
// code deleted for brevity
@Override
public String barTest() {
return unitTest;
}
} // FooServiceImpl
I copied/implemented the TestEnvironment and LocalServiceTestCase
classes as shown on
http://code.google.com/appengine/docs/java/howto/unittesting.html.
Then, I implemented the following:
public class ServerTest extends LocalServiceTestCase {
ApiProxyLocalImpl proxy = (ApiProxyLocalImpl)
ApiProxy.getDelegate();
FooServiceImpl server = (FooServiceImpl ) proxy.getService
(com.foo.server);
String result = barTest(); // produces
java.lang.NullPointerException
assertEquals(unitTest, result);
} // ServerTest
I got the java.lang.NullPointerException on this line String result =
barTest();
My environments: GAE 1.25, GWT 1.7, Eclipse-Galileo on Windows Vista.
I am new on this. What did I do wrong?
Thanks in advance for your help.

[appengine-java] Re: makePersistent() question
The local_db.bin shows up now.
It seems that I have to wait for a minute or two before it shows up on
the war\WEB-INF\appengine-generated.
