[appengine-java] new in 1.2.8: "relationship fields of type . This is not yet supported."
I've got some classes that extend a base class. This base class
implements some simple functions (like hashCode() and equals() ect.)
in a generic way so I don't have to keep writing those methods over...
and over... and over again. It also is the central place for entities
"id" field:
@Inheritance(customStrategy = "complete-table")
@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class BaseBean implements IsSerializable, Serializable,
Identifiable
{
private static final long serialVersionUID = 1L;
@NotPersistent
private Integer hash;
@PrimaryKey
@Persistent(valueStrategy=IdGeneratorStrategy.IDENTITY)
private Key id;
@Override
@SuppressWarnings("unchecked")
public boolean equals(Object obj)
{
if (this == obj)
{
return true;
}
if (obj == null)
{
return false;
}
boolean equal = false;
if (getClass().equals(obj.getClass()))
{
BaseBean that = (BaseBean) obj;
Object thisId = this.getId();
Object thatId = that.getId();
if (thisId != null && thatId != null)
{
equal = thisId.equals(thatId);
}
}
return equal;
}
@Override
public int hashCode()
{
if (hash == null)
{
hash = getId() == null ? super.hashCode() :
getClass().getName
().hashCode() ^ getId().hashCode();
}
return hash;
}
getters/setters...
}
pretty much every entity class in my model extends this class.
I didn't have to have the jdo annotations on this class in 1.2.6,
however, right after upgrading to 1.2.8, I had to make this class
PersistenceCapable otherwise datanucleus started to complain that it
wasn't enhanced (which, was never a problem before) In fact, this
class isn't persisted, there's never a case where the runtime of a
persisted bean is ever BaseBean (it's always an instance of a sub-
class). So, I added the above annotations, and things were working
fine, until later on in my tests, I had a class with multiple
relationships. I.E. this class has a one-to-one relationship with
class A and a one-to-many relationship with instances of class B (both
of which extend BaseBean, but otherwise share no inheritence
attributes):
@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class ActivityReservation extends BaseBean implements
Comparable
{
@Embedded(
members={
@Persistent(name="key", column="activityKey"),
@Persistent(name="name", column="name"),
@Persistent(name="pricingModel",
column="pricingModel")
}
)
@Persistent(defaultFetchGroup="true")
private ActivityFK activity;
@Embedded
@Persistent(defaultFetchGroup="true")
private ActivityLaunchFK launch;
@Persistent
private RatePlan ratePlan;
@Persistent
private BigDecimal totalCost;
@Persistent
private List guests = new ArrayList();
getters/setters...
}
@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class RatePlan extends BaseBean
{
@Persistent
private String name;
@Persistent
private BigDecimal adultPrice;
@Persistent
private BigDecimal youthPrice;
@Persistent
private BigDecimal unitPrice;
@Persistent
private PricingModel pricingModel;
@Persistent
private boolean active = true;
.
}
simple enum:
public enum PricingModel implements IsSerializable, Serializable
{
PER_GUEST("Per Guest"),
PER_UNIT("Per Unit"),
BOTH("Both");
private final String label;
private PricingModel(String label)
{
this.label = label;
}
public String getLabel()
{
return label;
}
public String toString()
{
return getLabel();
}
}
embedded classes (these don't extend BaseBean):
@PersistenceCapable(identityType=IdentityType.NONDURABLE)
public class ActivityFK
{
@Persistent
private Key key;
@Persistent
private String name;
@Persistent
private PricingModel pricingModel;
}
@PersistenceCapable(identityType=IdentityType.NONDURABLE)
public class ActivityLaunchFK extends
AbstractKeyReference
{
@Persistent
private Key key;
@Persistent
private Date startDate;

Re: [appengine-java] Re: new in 1.2.8: "relationship fields of type . This is not yet supported."
well, I should clarify:
BaseBean used to just hold the field id:
private Key id;
public Key getId()
{
return id;
}
public void setId(Key id)
{
this.id = id;
}
and subclasses would override this method and put the appropriate JDO
annotations in. I was doing this because inheritance of this type
wasn't supported when I stared writing my app:
public class SomeSubClass extends BaseBean
{
@Override
@PrimaryKey
@Persistent(valueStrategy=IdGeneratorStrategy.IDENTITY)
public Key getId()
{
return super.getId();
}
public void setId(Key id)
{
super.setKey(id);
}
...
}
now, again, I was only doing this as a fill-gap because I knew that
subclassing and persisting a super class's fields would be supported
in a future release of the sdk.
so, when I first updated to 1.2.8, I didn't change anything about any
class. i.e. BaseBean was still a simple POJO with no annotations, and
simply had a field/property in common
with it's persistable sub-classes. I'm not sure why JDO would feel
the need to have BaseBean persisted in this case, given that the only
fields on that class are clearly overriden in it's subclasses.
However, that aside, it still seems like a problem if you have 2
relationships, one of type one-to-one and another of type one-to-many
that are completely different (both at compile time and at runtime)
that *happen* to share a common ancestor (which is never persisted)
and your persistence wrapper thinks they are realationships of the
same data type.
not sure if I'm making that clear, sorry I left out that detail in the
first place, but my main point is independent of it: the relationships
are different, with different comple and runtime types. They
shouldn't ever be considered the same type. I mean, everythings an
Object but you don't get this error when that happens.

According to that link, this should work to query subclasses:
tx.begin();
Extent e = pm.getExtent(com.mydomain.samples.store.Product.class, true);
Query q = pm.newQuery(e);
Collection c=(Collection)q.execute();
tx.commit();
Is this supported or not. I can't get it to work using
@PersistenceCapable(identityType = IdentityType.APPLICATION)
@Inheritance(customStrategy = "complete-table")
public abstract class TestDN {
...
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public static class TestSubDN extends TestDN {
...
}
}
It's persisting fine and I can retrieve it if I use for example
pm.getObjectById(TestDN.TestSubDN.class, key);
pm.getObjectById(TestDN.class, key); fails though.
this is under 1.2.8

Re: [appengine-java] Re: new in 1.2.8: "relationship fields of type . This is not yet supported."
oh, forgot to mention:
if "according to the JDO specs" a non-persistent super class can have
a field that is overridden by it's persistent sub-classes, then it
seems like a bug that I was getting runtime errors saying that
BaseBean isn't persistable when trying to persist a subclass of
BaseBean that was persistable:
Persistent class "Class com.resmark.client.model.BaseBean does not
seem to have been enhanced. You may want to rerun the enhancer and
check for errors in the output." has no table in the database, but the
operation requires it. Please check the specification of the MetaData
for this class.

[appengine-java] Re: new in 1.2.8: "relationship fields of type . This is not yet supported."
Let's be clear here, if you have
public class Base
{
private long id;
public long getId()
{
return id;
}
public void setId(long id)
{
this.id = id;
}
}
@PersistenceCapable
public class Sub extends Base
{
@PrimaryKey
@Persistent
public long getId()
{
return super.getId();
}
public void setId(long id)
{
super.setId(id);
}
}
and persist a Sub, then ***DataNucleus*** will *not* insist that the
superclass is persistable. This is based on all DN datastore plugins
except GAE/J. If GAE/J does cause this then it is a bug in that plugin
and raise a bug on them, with stack trace and exception etc etc.
Also to be clear, the JDO and JPA specs do *not* allow magical
persistence of a field of a non-persistable superclass, unless you do
an override in a subclass like what you did there (to make it a
persistable property). You will *always* need that override.

Re: [appengine-java] Re: new in 1.2.8: "relationship fields of type . This is not yet supported."
right, we're certainly on the same page on what should/shouldn't be persisted. I have that override on every single class that subclasses BaseBean. I would never expect JDO/datanucleus or any other framework for that matter to "magically" persist a field in a non-peristable super class. That's why I override it in every subclass. Again, I had it in there as a place holder until GAE supported persisting super class fields in subclasses. in the release notes of 1.2.8 of GAE, it indicates such functionality is available, so I removed my overrides, made BaseBean persistable and started testing. Once I saw the error in my original message, I reverted everything back to a state where BaseBean is not persistable, and in fact, it is abstract and I removed the implementation of the "id" field and property getter/setters and migrated that all down to each subclassing bean. So, given my code above, no one should be requiring BaseBean to be persistable or even enhanced. Good tip on the point that a plugin may be causing this, here is the stack trace I posted earlier: Persistent class "Class com.resmark.client.model.BaseBean does not seem to have been enhanced. You may want to rerun the enhancer and check for errors in the output." has no table in the database, but the operation requires it.

[appengine-java] Re: Datastore Statistics vs. Quota
Hello Eric, thank you for your update. In fact I was suspecting the index or other management data. But it is hard to believe that it leads to such a big overhead. I mean it is enormous to have an index that is 10 times more than the actual data, don't you think so? Furthermore in the datastore statistics they already list so called "Metadata". It is consuming about 44% of the space. I think that this is the index, is it not? Maybe you are right an we got to wait. The statistics are already a great new feature to better understand things.

[appengine-java] possible to split web.xml ?
Hi, I have some (eclipse) projects which extend a main project, in other words, a project is sharing its source with all other projects (using junctions). Hence, projects can use main project's source as if it belong to itself. The advantage is that I can update main project's source in any project and it gets updated in all apps, but not everything, if I add a new servlet I need to manually append that servlet's mapping to each project's web.xml . Is any way, like, I keep one web.xml for my main project and one web.xml for child project (i.e. splitting web.xml into two files) and while in deploying project App Engine use both web.xml files to build servlet mappings ?

Re: [appengine-java] Re: /a/domain.com/ Logic
I'd suggest that you add your single app to your customer's apps account under a dedicated alias. E.g. if your customer's domain is customer1.com you would add the app as yourapp.customer1.com. You repeat this for every customer's google apps domain. Then in your application you can identify which customer's domain is used by calling javax.servlet.ServletRequest.getServerName() Best regards, Stephan 2009/12/6 patrick > > Hello > > I'm trying to build an application wich can be deployed to diffrent > google apps custmer, and each of them shoud have there own enviorment, > like gmail, docs, ... > But i don't like to deploy it to each customer app engine.

Re: [appengine-java] possible to split web.xml ?
No, this is not currently possible. I believe Servlet 3.0 adds support for web.xml fragments, which is likely what you want.

If you look at the article, it doesn't seem that out of place. Remember that by default, two indexes are built for every property, EntitiesByProperty ASC and EntitiesByProperty DESC. If you look at the number of fields in the corresponding tables (see article), and if your entity has 5-10 fields, I would not be surprised by such an overhead.

Re: [appengine-java] possible to split web.xml ?
You might try leveraging one of the MVC frameworks which supports inheritance for its action mapping files. Xdoclet may be another alternative worth investigating for a lower level build time composition of web.xml (although I haven't used it in the GAE / Eclipse context). It was a great ant tool for generating EJB descriptors back in the olden days.

[appengine-java] reverse index on __key__?!
Hi, I'm using the Java low-level Datastore API, in a local unit test (as described here: http://code.google.com/appengine/docs/java/howto/unittesting.htm): I'm trying to run a prefix search on __key__ (which I generated in the first place), as per the usual range-query hack: q.addFilter(Entity.KEY_RESERVED_PROPERTY, Query.FilterOperator.GREATER_THAN_OR_EQUAL, prefix); q.addFilter(Entity.KEY_RESERVED_PROPERTY, Query.FilterOperator.LESS_THAN, prefix + '\ufffd'); This fails to return any results. Note, that this technique works for all other properties, just not __key__. It's my impression that __key__ does not have a descending index by default. So, I've tried adding this to datastore-index.xml: But this had no impact. In fact, based on a quick trace, I've seen no evidence that the GAE code invoked during the unit test even tries to open this file. I believe this might be a bug in the AppEngine implementation (shouldn't an exception be thrown if there's no index on the queried field)? Or at least something that was overlooked... Is there a workaround? Thanks, Viktor -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Weird datastore bugs "update the same entity twice" and "operate on multiple entity groups"
I have written a unit test for appengine 1.2.8 with JDO and eclipse
3.5. You can see them at the bottom of the message.
Here is my model: Class A <---One to many bidi---> B ---One to many---
> C ---One to One---> D
1- My first test generates a "can't update the same entity twice in a
transaction or operation" although I don't do several updates.
Strangely, it works if I don't update the email field of object A, or
if I change the private member variable "_expList" in object A by
"_aList"...
2- Test 2 fails with "can't operate on multiple entity groups in a
single transaction." although I *should* have a single entity group
where C is an indirect child of A. It seems to work if I use a List of
C instead of a Set of C within class B. It also works if I manually
set the Key of object C or if I don't insert object A first in
database.
3- Fails because when I use loadByKEy, my list of B is not filled
(whereas the object returned by update() is filled). In the same way,
I can't get a request working, all are returning null. However a fetch
plan with a depth of 3 and defaultFetchGroups are defined.
This was working in appengine 1.2.1.

[appengine-java] What's the right way to use PersistenceManager?
Hi, I'm new in JDO, so I think this problem may sounds stupid...
I'm working on my application on App-engine, and feel really confused
about how to use the PersistenceManager in my app...
1) At the very beginning I tried to maintain only one static pm
instance in my app, but I found that when I try to update the entities
in datastore, it does not write back, since I do not close the pm.
2) Then, I tried to get a new pm in every request, and after the
request I close it. But I still store the pm as a static field in a
DaoBase class. the code looks like:
PersistenceManager pm = PFM.get().getPersistenceManager();
DaoBase.setPm(pm);
do the request...
DaoBase.getPm().close();
DaoBase.setPm(null);
But when multiple requests come concurrently, things becomes messy and
sometimes the DaoBase.getPm() will returns null during a request.
3) Use new pm each time when reading the datastore, then detach the
object from pm, close the pm. Then during update time, use a new pm to
update it. But the problem here is when there is some owned
relationship between datastore entities, a detatched object will not
fetch the data automatically, like:
/
class Address {
}
class Employee {
private List addressList;
public List getAddressList() {
return addressList;
}
}
///
the getAddressList() will always return null.
So...What is the right way to use PersistenceManager?

[appengine-java] JDO bug (entity groups and double update)
Hi everybody,
My model contains a Class A <---Bidi one to many---> B ---one to
many---> C ---one to one---> D.
I wrote 3 unit tests with appengine 1.2.8 and JDO on eclipse 3.5 which
generate an error.
It looks like a bug in JDO to me but I may be wrong:
1- org.springframework.orm.jdo.JdoSystemException: can't update the
same entity twice in a transaction or operation; nested exception is
javax.jdo.JDOException: can't update the same entity twice in a
transaction or operation
NestedThrowables:
java.lang.IllegalArgumentException: can't update the same entity twice

(JdoTransactionManager.java:503)
at org.springframework.orm.jdo.JdoTransactionManager.doCommit
(JdoTransactionManager.java:427)
However (see the code below), when I change the member variable
expList of class A then it works. An other way is not to call setEmail
of class A (but if I set the firstName which is also a String then it
works)...
This look like a JDO bug or bug to me.
2- com.testgae.xp.server.dao.DaoException:
javax.jdo.JDOFatalUserException: Illegal argument
NestedThrowables:
java.lang.IllegalArgumentException: can't operate on multiple entity
groups in a single transaction. found both Element {
type: "A"
id: 1
}
and Element {
type: "C"
id: 3
}
Here I don't understand because A and C should be in the same group.
There are only owned relationship between them. If I create the
hierarchy A->B->C->D all at once it works. But not if I do A->B and
then ->C->D like in my second test. Is it a bug in my code or a JDO
bug again?
If I set manually the key of class C (as a child of B) then that
works... Another way to make it works is to change the Set of C to a
List of C in class B.
Isn't it a bug in JDO or something?
3- my "childs" are never loaded. But if I used the updated object
returned by my DAO instead of loading it from the datastore, then that
works. All my requests return null. I can't understand why because
this was working in appengine 1.2.1.
This is likely something about my code is missing or wrong but I can't
see what.

project ready to import :D:

[appengine-java] Nearly doubled CPU usage since december 3rd
Hi, Our appengine instance is seeing nearly double the CPU usage since december 3rd compared to before, without an increase in number of requests. We have been trying to debug this, but it's hard to make sense of the numbers provided by appengine. A typical request that we do has numbers like this: Request Time/Latency: 76ms Milliseconds of CPU Time Consumed: 210cpu_ms 113api_cpu_ms We always used to have ~100ms api cpu_ms, but cpu_ms used to be more like 50ms or so. We added logging on the time of entry and exit of doGet() and there was 58 ms difference in this case. How is it possible to have 210cpu_ms, which is ~100ms more than the api usage, while the request only lasted 58 ms (or 76 ms according to the appengine number)?

[appengine-java] Youtube Direct Application deployment time JSP Compilation Error
I am getting this error when deploying the youtube direct application to google app engine. Unable to update: com.google.appengine.tools.admin.JspCompilationException: Failed to compile the generated JSP java files. Some forum suggested me to do these steps 1. Copy tools.jar into the AppEngine lib/shared directory. 2. Modify appcfg.cmd so it fully-qualifies the reference to java.exe in the JDK/bin directory. I did them but still no luck. Any suggestion will be welcomed. Thanks, Muhammad Umair -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Querying "parent" side of unowned relationship
What is the most efficient way of querying the "many" side of an
unowned relationship. E.g., assuming the standard JDO annotations are
applied:
class Person
{
Set foods;
}
class Food
{
Key key;
String name; // unique
}
Given the name of a Food, how can I best get the list of Person
objects that reference it in it's food Set?

[appengine-java] Repeated "Request was aborted" errors
Hi, I am getting errors on every other request like this: Request was aborted after waiting too long to attempt to service your request. Most likely, this indicates that you have reached your simultaneous dynamic request limit. This is almost always due to excessively high latency in your app. Please see http://code.google.com/appengine/docs/quotas.html for more details. which are then followed by a restart of the container and then the next request will give the error again. As the container is restarting and only one request is processes I think something else must be causing the error apart from too many connections. Any ideas?

I cannot tell you why your CPU time seems to have increased, but know that cpu_ms and api_cpu_ms are not using wall-clock milliseconds, but "virtual" milliseconds, defined for the purpose of billing. They more or less correspond to milliseconds on an old-ish machine (some kind of Intel 1.2GHz, IIRC) -- and they depend on the type of request. They are essentially an abstract unit. The app engine documentation gives more detail: http://code.google.com/appengine/docs/quotas.html Google might have been better inspired to not label this unit "millisecond". "Disney dollars" are meant to confuse you -- that might not have been a good example to follow. P.S. Turns out, Disney dollars are convertible and pegged to the USD.

Re: [appengine-java] Re: 1.2.8 SDK Prerelease - help us verify!
Hi Dom,
We definitely should have updated our unit-testing documentation to include
more information for testing with queues. I'll make sure this gets
addressed. In the meantime, I believe this should do what you want:
QueueFactory.getDefaultQueue().add(TaskOptions.Builder.taskName("task29"));
ApiProxyLocalImpl proxy = new ApiProxyLocalImpl(new File(".")){};
LocalTaskQueue ltq = (LocalTaskQueue)
proxy.getService(LocalTaskQueue.PACKAGE);
ltq.flushQueue(QueueFactory.getDefaultQueue().getQueueName());
QueueFactory.getDefaultQueue().add(TaskOptions.Builder.taskName("task29"));
You can use LocalTaskQueue.getQueueStateInfo() to inspect and assert on the
state of your queues:
LocalTaskQueue ltq = (LocalTaskQueue)
proxy.getService(LocalTaskQueue.PACKAGE);
for (QueueStateInfo qsi : ltq.getQueueStateInfo().values()) {
for (QueueStateInfo.TaskStateInfo ti : qsi.getTaskInfo()) {
System.out.println(ti.getTaskName());
}
}
Hope this helps,
Max

Re: [appengine-java] local google app engine server in Netbeans
You'll have to stop the server when you redeploy. If you run in "debug" mode, the JVM will reload classes that you recompile so you would only need to redeploy when you change configurations (web.xml, appengine-web.xml, etc). I'm not familiar with the NetBeans plugin, so I can't comment on why this may be happening, but when I use the IntelliJ plugin, it will ask me whether I want to kill the existing JVM, detach or cancel. If you really want to restart the process, you would want to "kill" so the process doesn't detach and take up the port you need.

Re: [appengine-java] Re: Datastore Statistics vs. Quota
Toby, There's another thing to be aware of: sessions are backed with the datastore. If you have sessions enabled, you may want to write a scheduled task that clears session data.

Re: [appengine-java] How to use jmsn on GAE?
Yes, App Engine suggests external JARs. What is likely happening is that the library is using a class that is not on the whitelist. Since it is an MSN Messenger app, this likely has to do with classes that require socket communication, which we do not allow. Have you looked into the XMPP service?

Re: [appengine-java] Re: problems with SDK 1.2.8 and (local) task queues timing out...
Local task execution is using the local UrlFetchService implementation with its default timeout: 5 seconds. So, if the url that your task hits takes more than 5 seconds to respond you'll see this exception. However, this exception is from the client of the task url, not the task execution itself. The client will timeout after 5 seconds but the task should still execute to completion - we don't interrupt it. Please let me know if that's not the case. Now, 5 seconds is clearly not enough time since the request limit for apps is 30 seconds. This is a bug, and it's already fixed. It should go out with the next SDK. In the meantime just try to ignore the timeouts. As for retries, this is a known limitation: http://code.google.com/appengine/docs/java/taskqueue/overview.html#Task_Queues_and_the_Development_Server We'll get this brought in line with production shortly.

Re: [appengine-java] How to use jmsn on GAE?
Leon, I may have originally misdiagnosed your issue. Where did you place the JAR file? If you placed it in your JDK's lib/ext directory, it could cause dev_appserver to incorrectly think the class belongs to a package that we don't support. You'll need to put this JAR file under WEB-INF/lib and make sure it's in your build path. On Mon, Dec 7, 2009 at 10:58 AM, Ikai L (Google) wrote: > Yes, App Engine suggests external JARs.

[appengine-java] Re: problems with SDK 1.2.8 and (local) task queues timing out...
sorry I should have been more precise, essentially I am concerned about blowing the 30sec per request processing/duration limit previously I was bulk uploading csv files and parsing them into POJOs then persisting them via JDO to pre-populate my app data ... I was encountering both the 5sec DS operation and 30sec processing quota exceptions with this model ... So, all I do initially is upload the CSV in Gae VFS ... then I schedule a task the task then batches lines from the file, parses, then pesists them ... if it gets an exception then it "quickly" (I hope) (repeatedly) reschedules another task to upload ...

Re: [appengine-java] Re: problems with SDK 1.2.8 and (local) task queues timing out...
Your approach sounds fine. As an alternative you could schedule the next task up front, then check to see if there is any work to be done, then proceed. That way you'll always have the next task scheduled no matter what might go wrong during processing.

Re: [appengine-java] Now available: JDO/JPA preview release with inheritance support
Hi Shawn,
My apologies, but the Extent example on the page you referenced is not
supported because we have no way to efficiently query across different types
(datastore queries are either by kind, by ancestor, or both).
pm.getObjectById(TestDN.class, key) will fail if the persistent type of the
entity referenced by key is not TestDN.class. If they key you're passing
identifies a TestDN.TestSubDN instance then the failure is expected.
Thanks,
Max

Re: [appengine-java] What does true do?
Yes, pre-compilation reduces the time to load an application. This will benefit you on your first request after a deploy, after you've been cycled out or if more application instances are created to scale up with your load. You will see up to 30% improved loading time on your first request. Pre-compilation works by doing a bit of class loading work ahead of time in the App Engine environment before the request comes in. It's still opt-in, so you'll need to enable it if you want it.

[appengine-java] Application Memory Usage
Hi, Jason (Google) has mentioned that there is a limit on the amount of memory an application can consume in another thread: "There is an upper limit to the amount of memory your app can consume, but it's more than reasonable for the type of applications that App Engine is built to serve. If your application surpasses this limit, an exception will be thrown. " What is the limit (if not an exact value an approximate value)?

[appengine-java] I'm afraid to migrate my application to the GAE4J
Hello, I care for an application that updates every day somewhere around 1 million rss (6 times a day) and we are looking for alternatives to reduce costs, and among the cheaper alternative is the Gae4j. But I'm still a little afraid to migrate the application, considering the limits that exist in gae4j, especially as the problem of updating the rss. These questions arose because my application has a strong dependence on long running processes and background tasks. My question is: can I migrate my application to the cloud without problems? Did not have my application blocked for exceeding the quota limit allowed, even being willing to pay for all necessary resources? Another question: does the gae4j allows me to run 100 tasks per second in a queue and increase my bucket size? I know I have to do a refactoring in my code, but I believe it will be worth it, mainly because of the scalability and price. If any expert gae4j can help me, I appreciate it. Thanks. sorry my poor english. Fulvius -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Re: [appengine-java] Re: Processing incoming email
Sam, I understand your confusion. I'm looking into it. The code I posted was to convert an InputStream to the proper format. My understanding is that 1.2.8 actually fixed the issue, so our code should actually end up being simpler and closer adhere to standard Java incoming mail processing. Any help the community provides would be much appreciated! The faster we can all get to the bottom of this, the faster I can get the docs updated.

[appengine-java] Re: 1.2.8 SDK Prerelease - help us verify!
Max,
With your settings added to my MockAppEngineEnvironment.tearDown()
method, there's no more issue.
Personally, I think using my MockQueue which stores the submitted
TaskOptions instances is easier to use. I can access each attributes
individually (URL, method, parameters, etc.) with the TaskOptions
getters. When dealing with TaskStateInfo instances, I need to extract
the submitted parameters from the URL or from the body (depending on
the method being GET or POST/PUT). A bit cumbersome to me ;)
Thanks for your help,
A+, Dom

Re: [appengine-java] Re: 1.2.8 SDK Prerelease - help us verify!
I'm glad to hear things are working for you. If MockQueue works best for
you then by all means stick with that - that's more of a "pure" unit test
anyway since it doesn't depend on the actual local task component.

[appengine-java] Xmpp Log Appender
Hi all,
I've created the log appender that write a log out through the
XMPPService for sl4j and logback.
XmppAppender.java
---
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.*;
import com.google.appengine.api.xmpp.*;
public class XmppAppender extends AppenderBase {
private XMPPService service = XMPPServiceFactory.getXMPPService();
private String notifyTo;
public String getNotifyTo() {
return notifyTo;
}
public void setNotifyTo(String notifyTo) {
if (notifyTo == null || notifyTo.isEmpty()) {
throw new IllegalArgumentException();
}
this.notifyTo = notifyTo;
}
@Override
protected void append(ILoggingEvent eventObject) {
JID jid = new JID(notifyTo);
Message message = new MessageBuilder()
.withMessageType(MessageType.CHAT)
.withRecipientJids(jid)
.withBody(getLayout().doLayout(eventObject))
.build();
switch (service.sendMessage(message).getStatusMap().get(jid)) {
case SUCCESS:
return;
case INVALID_ID:
throw new LogbackException("failed to append log event for
invalid id:" + jid);
case OTHER_ERROR:
throw new LogbackException("failed to append log event for
unknown error:" + jid);
default:
throw new AssertionError();
}
}
}
---
sample logback.xml as following:
logback.xml
---
developper-account*at*gmail.com
%-5p %d [%t] %m%n
---
Then, invite *at*appspot.com to the desired GTalk account.
That's it!! Enjoy your Log Life!!
Since XMPPService works for the deault version only, you can not use
this appender for the others.

Re: [appengine-java] Re: new in 1.2.8: "relationship fields of type . This is not yet supported."
Thanks for the link Max. Having BaseBean be PersistenceCapable isn't really a requirement. It'd be nice, 'cause pretty much every bean in my class structure is going to have an id field, a getter/setter and the exact same JDO annotation metadata on that field. It'd be nice to just have that defined once in a base class. However, it's no big thing to just implement an id field on every class, so I can certainly do without BaseBean being persistable. However, I'm noticing above mentioned errors when I make BaseBean a plain-ol class with no persistence metadata (i.e. it just implements equals and hashCode) and the appengine datanucleus plugin seems to be telling me that BaseBean needs to be enhanced. So, either way I go, I'm running into issues. I'd like to try to get to the bottom of why my non-persistable base class is being required to have been enhanced. Perhaps something is wrong with my configuration/meta data? perhaps a bug? any feedback/suggestions would be great. thanks! -bryce On Mon, Dec 7, 2009 at 12:04 PM, Max Ross (Google) wrote: > I need to investigate the requirement that BaseBean be PersistenceCapable, > but the relationship exception you're getting is most likely the result of a > separate bug.

[appengine-java] Re: oid is not instanceof javax.jdo.identity.ObjectIdentity
Max, have you had a chance to try this out? I'm not trying to push or
anything, just wanted to make sure my last message didn't get
overlooked. I've noticed this error sort of... randomly popping up in
places where it preivously hasn't as of late. If i'm missing
something in my configuration, I'll be happy to change it, I'm just
not sure what I'm missing.
again, I really appreciate your taking the time to help me debug this
issue.
thanks,
-bryce
