[appengine-java] Re: JDO problem : oid is not instanceof javax.jdo.identity.ObjectIdentity
I managed to reproduce the issue with a simplified model.
Notice that the same code seemed to pass the test yoesterday...not
today.
I can't attach files so I paste the model here
@PersistenceCapable
class Inner{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
Key key;
}
@PersistenceCapable
class Outer{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
Key key;
@Persistent
Inner inner;
public Outer(){
inner = new Inner();
}
// public void setInner(Inner in){
// inner = in;
// }
}
@PersistenceCapable
class Container{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
Key key;
@Persistent
ArrayListOuter outers;
@Persistent
ArrayListInner inners;
public void addOuters( int n){
outers = new ArrayListOuter();
for (int i = 0; i n; i++){
outers.add(new Outer());
}
}
public void addInners(int n){
inners = new ArrayListInner();
for (int i = 0; i n; i++){
inners.add(new Inner());
}
}
}
public class TestJDOException {
private final LocalServiceTestHelper helper =
new LocalServiceTestHelper(new
LocalDatastoreServiceTestConfig());
private static final PersistenceManagerFactory pmf =
JDOHelper.getPersistenceManagerFactory(transactions-optional);
@Before
public void setUp() throws Exception {
helper.setUp();
}
@After
public void tearDown() throws Exception {
helper.tearDown();
}
@Test
public void testAddInners(){
Key key = null;
Container container = new Container();
container.addInners(1);
PersistenceManager pm = pmf.getPersistenceManager();
try{
pm.makePersistent(container);
key = container.key;
}
finally{
pm.close();
}
pm = pmf.getPersistenceManager();
try{
container = pm.getObjectById(Container.class, key);
System.out.println(container.inners);
System.out.println(container.outers);
}
finally{
pm.close();
}
}
@Test
public void testAddOuters(){
Key key = null;
Container container = new Container();
container.addOuters(1);
PersistenceManager pm = pmf.getPersistenceManager();
try{
pm.makePersistent(container);
key = container.key;
}
finally{
pm.close();
}
pm = pmf.getPersistenceManager();
try{
container = pm.getObjectById(Container.class, key);
System.out.println(container.inners);
System.out.println(container.outers);
}
finally{

}
}
}
First test passes, second fails. Every test adding Outers fails as
well.

[appengine-java] Re: JDO problem : oid is not instanceof javax.jdo.identity.ObjectIdentity
Looks like the problem is due to a combination of two factors:
*Class Inner has two parents, Outer and Container
AND
*Class Container mantains a list of Inners.
Changing to
@PersistenceCapable
class Container{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
Key key;
@Persistent
ArrayListOuter outers;
@Persistent
Inner inners;
public void addOuters( int n){
outers = new ArrayListOuter();
for (int i = 0; i n; i++){
outers.add(new Outer());
}
}
public void addInners(int n){
for (int i = 0; i n; i++){
inner = new Inner();
}
}
}
Makes everything work fine.
I have a very similar model which works well in production (it's been
up for nearly one month now).
Hope this helps people facing similar issues. Maybe a short note in
documentation could help.
Regards
Lorenzo

[appengine-java] Re: Fwd: entity update question
Incorrect, Vik. You do not need to call pm.makePersistent(e) in order
to save changes made to an already persistent object. You use
makePersistent(..) to cause new instances to become persistent, to
merge detached instance state into the persistence context, or to
attach detached instances into the persistence context in place.
The act of changing the state of a persistence capable instance marks
the instance as dirty, which JDO will then flush at or before the
commit of the transaction governing your operation.
Calling pm.makePersistent(x) on an instance x that is already
persistent is a no-op. If x is detached and you want to merge the
changes incurred while detached into the persistent object graph, then
do the following:
Employee persistentEmployee = pm.makePersistent(detachedEmployee);
The PersistenceManager will take the detachedEmployee, find its
persistent counterpart by id (persistentEmployee), apply any changes
found in detachedEmployee to persistentEmployee, then return
persistentEmployee. This happens assuming that the option
javax.jdo.option.CopyOnAttach is true. If false and the PM has no
Employee with that oid currently in the persistence context, then
detachedEmployee itself transitions to persistent-dirty and is itself
returned. If false and the PM already has an Employee with the same
oid in the persistence context, then a JDOUserException will be
thrown.
I highly recommend a read of the JDO specification. It's really well
written, if I don't say so myself... :)
HTH,
Matthew

Hie
I do for create like
try{
Employee e = new Employee();
pm.makePersistent(e);
}finally(){
pm.close();
}
For update case I am getting the entity by id and updating one of the
attribute like
Employee e = pm.getObectById(empPK, Employee.class);
e.setSalary(1000);
the question is do i need to call the below statement in this case as well?
pm.makePersistent(e)

[appengine-java] Content-Length header on POST request to GAE
Dear community, I've searched on Google and on this forum for an answer to my question, but nothing turned up, so here goes: I am trying to set the Content-Length header in my response from within the servlet, like this: response.setContentLength(someString.getBytes().length); The request is a POST request. It works on the test-server started from within Eclipse (and tested with curl), it doesn't work on the GAE production server -- the header field Content-Length simply gets discarded. These are the headers from the response on GAE production: HTTP/1.1 200 OK Content-Type: text/xml; charset=utf-8 Date: Thu, 14 Oct 2010 13:24:48 GMT Server: Google Frontend Cache-Control: private, x-gzip-ok= Transfer-Encoding: chunked Does it have something to do with the compression and/or the chunked encoding? Is it still possible to set the content-length somehow? If not, why does GAE supress this header? Thank you very much in advance!

[appengine-java] Strange exception with my app
Hi google appengine team, Since today, I have been getting continuously the exception reported below. Yesterday I am not sure, but the day before yesterday it worked for sure. I have more apps that use the same library and all of them keep throwing the same exception. You can reproduce it uploading this xsl file: http://www.4shared.com/file/uefUC7KX/simple.html on this servlet: http://almaoffice0.appspot.com/testPDF.jsp app id: almaoffice0 and domodentweb. In the development server, everything works fine (just like before). I need information about the issue pretty fast because the second app is a production one and I need to know what decision to take. Thanks in advance.

Re: [appengine-java] Re: Need to include com.google.gdata.client in the deployment for GAE?
Not at the moment, though the new builtins function in app.yaml would certainly allow for it. The reason I think it wouldn't is because the GData client isn't maintained by a team that works closely with App Engine, but if there is a demand, there's nothing else really holding us back. I don't see including it as that big of a deal, though, so in my eyes this feature would be low priority. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Thu, Oct 14, 2010 at 9:19 AM, Saqib Ali docbook@gmail.com wrote: Thanks Ikai.

[appengine-java] Any changes to access levels in com.google.appengine.api.datastore recently?
Has anything changed with class access levels (public vs. private) in the production datastore code in the last day or so? I've had a Clojure app running for several weeks and starting last night, whenever I try to access the datastore, I get the error below. It could be a bug in the library I'm using (appengine-clj) or even in Clojure's dispatch code, but I just want to understand if anything has changed server-side that might have triggered it. The application still works on the dev appserver v1.3.7. java.lang.IllegalArgumentException: Can't call public method of non-public class: public com.google.appengine.api.datastore.Transaction com.google.appengine.api.datastore.BaseDatastoreService.getCurrentTransaction(com.google.appengine.api.datastore.Transaction) at clojure.lang.Reflector.invokeMatchingMethod(Reflector.java:85) at clojure.lang.Reflector.invokeInstanceMethod(Reflector.java:28) at appengine.datastore.service$current_transaction.invoke(service.clj:72) at appengine.datastore.service$put_entity.invoke(service.clj:131) at appengine.datastore.service$fn__176.invoke(service.clj:149) at appengine.datastore.service$fn__136$G__116__141.invoke(service.clj:10) at com.redaranj.ledes.service.servlet$fn__1902$fn__1903.invoke(servlet.clj:17) at compojure.core$routes$fn__1706$fn__1707.invoke(core.clj:72) at clojure.core$some.invokeStatic(core.clj:2297) at compojure.core$routes$fn__1706.invoke(core.clj:71) at ring.middleware.params$wrap_params$fn__1468.invoke(params.clj:77) at ring.middleware.cookies$wrap_cookies$fn__1559.invoke(cookies.clj:123) at ring.util.servlet$make_service_method$fn__1881.invoke(servlet.clj:117) at com.redaranj.ledes.service.servlet$_service.invoke(servlet.clj:19) at com.redaranj.ledes.service.servlet.service(Unknown Source) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:511) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1166) at com.google.apphosting.utils.servlet.ParseBlobUploadFilter.doFilter(ParseBlobUploadFilter.java:97) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.runtime.jetty.SaveSessionFilter.doFilter(SaveSessionFilter.java:35) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java:43) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:388) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:418) at com.google.apphosting.runtime.jetty.AppVersionHandlerMap.handle(AppVersionHandlerMap.java:238) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:923) at com.google.apphosting.runtime.jetty.RpcRequestParser.parseAvailable(RpcRequestParser.java:76) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at com.google.apphosting.runtime.jetty.JettyServletEngineAdapter.serviceRequest(JettyServletEngineAdapter.java:135) at com.google.apphosting.runtime.JavaRuntime.handleRequest(JavaRuntime.java:261) at com.google.apphosting.base.RuntimePb$EvaluationRuntime$6.handleBlockingRequest(RuntimePb.java:8483) at com.google.apphosting.base.RuntimePb$EvaluationRuntime$6.handleBlockingRequest(RuntimePb.java:8481) at com.google.net.rpc.impl.BlockingApplicationHandler.handleRequest(BlockingApplicationHandler.java:24) at com.google.net.rpc.impl.RpcUtil.runRpcInApplication(RpcUtil.java:418) at com.google.net.rpc.impl.Server$RpcTask.runInContext(Server.java:572) at com.google.tracing.TraceContext$TraceContextRunnable$1.run(TraceContext.java:448) at com.google.tracing.TraceContext.runInContext(TraceContext.java:688) at com.google.tracing.TraceContext$AbstractTraceContextCallback.runInInheritedContextNoUnref(TraceContext.java:326) at com.google.tracing.TraceContext$AbstractTraceContextCallback.runInInheritedContext(TraceContext.java:318) at com.google.tracing.TraceContext$TraceContextRunnable.run(TraceContext.java:446) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:636) -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[google-appengine] Problem with query

When I build the qery like this: select from ... where myArray.startsWith(keyword), everything works fine. But the problem is, when I build a query, where I want to search for two keywords, the query doesnt give me results. Example: select from ... where myArray.startsWith(keyword1) myArray.stratsWith(keyword2) I don´t know why this doenst work, maybe somebody can help me?? Thanks.

[google-appengine] Re: what xml lib use
Hi I am going to assume your using python. You should look at elementtree. Its already in the standard python distribution and for many tasks its the simplest to use if it's all your own code. If you using some other tools then they may have dependencies on other specific parsers. If you have a look at googles own gdata library then you will find the atom.core uses elementtree for all of its xml parsing. So I think elementtree is a really good place to start. http://docs.python.org/library/xml.etree.elementtree.html Disregard all of this if you not using python ;-) Regards Tim On Oct 14, 3:28 pm, alf alberto@gmail.com wrote: hi gloogers we are starting to use a xml in ours gae enviroment we need choose one external library to manage xml object we can user sax, minidom and probably more.

[google-appengine] Re: what xml lib use
Also you should note in appengine the only way you have to talk to any remote service is via urlfetch (or urllib2 which is layered over urlfetch) or the xmpp service. You can't open sockets etc or use any non http(s) based protocol in appengine. Rgds Tim On Oct 14, 4:30 pm, Tim Hoffman zutes...@gmail.com wrote: Hi I am going to assume your using python.

I need to do another cleanup pass over the API to make a few more refinements. I pulled this code out of one of my apps, and tried to quickly refactor it to be a bit more generic. We are currently using basically the same code in three apps to do some really complex calculations. As soon as I get time I will get an example up showing how to use it for neat stuff, like overall, yearly, monthly, and daily aggregates across multiple values (like total dollars and quantity). The cool thing is that you can do all of those aggregations across various groupings, like customer, company, contact, and sales-person, at once. I'll get that code pushed out in the next few days.

Hopefully putting an ETA on the transactional task will relieve the write pressure, since usually it should be an old update with an out-of-date sequence number and be discarded (the update having already been completed in batch by the fork-join-queue).

The question is about slide #67 of his pdf, corresponding to minute 51:30 of his talk http://code.google.com/events/io/2010/sessions/high-throughput-data-p... I am wondering what is supposed to happen in the transactional task (bullet point 2c). Would these updates to the materialized view cause you to write too frequently to the entity group containing the materialized view? I think there are really two different approaches you can use to insert your work models. 1) The work models get added to the original entity's group. So, inside of the original transaction you do not write to the entity group containing the materialized view -- so no contention on it. Commit the transaction and proceed to step 3. 2) You kick off a transactional task to insert the work model, or fan-out more tasks to create work models :). Then you proceed to step 3. You can use method 1 if you have only a few aggregates. If you have more aggregates use the second method. I have a library I am almost ready to open source that makes method 2 really easy, so you can have lots of aggregates. I'll post to this group when I release it. And a related question, what happens if there is a failure just after the transaction in bullet #2, but right before the named task gets inserted in bullet #3. In my current implementation I just left out the transactional task (bullet point 2c) but I think that causes me to lose the eventual consistency. Failure between steps 2 and 3 just means _that_ particular update will not try to kick-off, ie insert, the fan-in (aggregation) task. But it might have already been inserted by the previous update, or the next update. However, if nothing else kicks of the fan-in task you will need some periodic cleanup method to catch the update and kick of the fan-in task. Depending on exactly how you implemented step 2 you may not need a transactional task. Robert Thanks! -- You received this message

[google-appengine] Outage of site due to cannot import name datastore_stub_util
This is a request for help from someone at google.

At 3.53pm on Oct 13 we had an error that said cannot import name
datastore_stub_util due to the launch of a new process. It's not
clear why a new process was launched since the previous requests were
not CPU intensive. It's possible that this one request was, but I
can't quite tell why. Every subsequent request to my application
results in an error: 'NoneType' object has no attribute 'exception'.
This error references a line main.py which says:

Re: [google-appengine] Problem with query
Hey Alex, I am guessing that under the hood App Engine breaks the startsWith into two filters that looks something like: myArray = keyword AND myArray keyword + z So when you add the second startsWith filter, you get: myArray = keyword AND myArray keyword + z AND myArray = otherword AND myArray otherword2 + z That is not going to work. You may be able to validate my theory by making the two keywords the same and seeing if you get results.

Re: [google-appengine] Outage of site due to cannot import name datastore_stub_util
You might try to deploy your code to a new version, then set the new
version to default. That will cause your app to reload.
I think Tim has a good idea, deploy the same code to two versions.
Then when you get a stuck / corrupt instance you can switch the
default version and be back in business.

I am wondering what is supposed to happen in the transactional task (bullet point 2c). Would these updates to the materialized view cause you to write too frequently to the entity group containing the materialized view? I think there are really two different approaches you can use to insert your work models. 1) The work models get added to the original entity's group. So, inside of the original transaction you do not write to the entity group containing the materialized view -- so no contention on it. Commit the transaction and proceed to step 3. 2) You kick off a transactional task to insert the work model, or fan-out more tasks to create work models :). Then you proceed to step 3. You can use method 1 if you have only a few aggregates. If you have more aggregates use the second method. I have a library I am almost ready to open source that makes method 2 really easy, so you can have lots of aggregates. I'll post to this group when I release it. And a related question, what happens if there is a failure just after the transaction in bullet #2, but right before the named task gets inserted in bullet #3. In my current implementation I just left out the transactional task (bullet point 2c) but I think that causes me to lose the eventual consistency. Failure between steps 2 and 3 just means _that_ particular update will not try to kick-off, ie insert, the fan-in (aggregation) task. But it might have already been inserted by the previous update, or the next update. However, if nothing else kicks of the fan-in task you will

[google-appengine] Google App Engine User Service redirection problem with IE
(THE FOLLOWING WAS ORIGINALLY POSTED IN THE GOOGLE GADGETS SUPPORT FORUM) Steps to reproduce issue: 1. Create a GAE Application that requires userservice.isUserLoggedIn() to return true. If not redirect to userservice.createLoginURL(your- app-url) 2. Add an iFrame or similar gadget to a Google Sites page. Set your GAE app as the content URL. The site should be on a Google Apps domain so that a Google Apps user must be logged in to access the site. 3. Access the page with Internet Explorer (I've been testing with version 8) Expected output: The hopeful expected output would be that the GAE app would immediately recognize that the user is logged in, and show its content. However, the workflow that seems to occur with Firefox and Chrome is as follows (and good enough for my purpose): 1. The user logs in to Google Apps before accessing the site. 2. The Sites page loads. 3. The gadget loads, and subsequently loads the GAE app. 4. The GAE app determines that the user is NOT logged in, and redirects the user to the generated login URL. 5. The resulting login URL pages recognizes that the user is already logged in, and redirects back to the GAE app 6. The GAE app now recognizes the user, and displays its content in the gadget's iframe. Actual results: With IE, the above workflow all seems to function the same with 2 exceptions: 1. The redirection to the login page and back seem to be slower, so that the login page is actually displayed in the gadget iframe for a brief moment. 2. Upon redirecting back to the GAE app, the app breaks out of the iframe filling the entire browser window. Any advice on how to prevent number 2 would be very helpful. Also, if anyone can advise on a way to have a GAE app's Userservice immediately recognize that the user is logged in without needing to do the login url loop would be even more helpful. RESPONSE IN GOOGLE GADGETS FORUM: The IE-specific issues are going to be related to App Engine and not gadgets, so I'd suggest asking this question in the App Engine forum. There are most likely headers being sent during App Engine authentication that direct some browsers (notably IE) to break out of frames. The App Engine team would know better than I if there are ways to mitigate this in certain contexts. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Google App Engine User Service redirection problem with IE
My problem with the behavior is that the user has already logged in to Google Apps BEFORE being presented the iFrame. Our GAE application in embedded in an iFrame to provide additional functionality to a Google Site. (The Site is not public, so requires a GApps login.) After performing the GApps log-in, I would think that I could access a Sites page with a GAE page embedded in an iFrame and have that work without needing to do a subsequent login. But if an additional log-in is required by the iFrame because of the sandbox-nature of an iFrame, then the resulting log-in redirection should occur within that context. Having it break out of the iFrame (which only occurs in Internet Explorer) makes no sense because in the context of the top- level browser window, the user is already logged in.
