[appengine-java] overcome onetomany limitation of 5000
hi all
i am modelling a unowned one-to-many relationship using list properties.
@Entity
public class User{
String name;
Boolean loggedIn;
@Basic
private ListKey friends;
}
all is good. i can run queries like
query = Select p from PositionUser p where p.friends = :userKey and +
AND p.loggedIn = true
However there is a limit on the number of index available per entity of
5000. (although i am hitting the limit at 2500 for some reason)
i have 2 problems with the current approach
#1. below the 5000 limit each addition to the friend list will require a
fetch of the entire list, then add item and then put to datastore.
this is rather expensive in CPU.
#2. How can i allow for 5000 in the onetomany?
any suggestion pls
-lp

[appengine-java] Servlet Filter is receiving a null chain parameter from time to time
Hi, I wonder if somebody else has seen this error before. My application has a Servlet Filter (that sets Namespace) for all urls, and, from time to time, the Filter receives a null as value for chain parameter from the platform, so I get a NullPointerException as I try to follow the chain with chain.doFilter(req, resp). I have seen this specially when accessing an RPC method. Thanks, Eduardo G. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Concurrent modification results in Entity being deleted
Hey I have an Entity which contains a ListEntity property that stores child entities. I have found a bug in my app where during concurrent modification of child entities all of the children in the parent entities list will be deleted. Firstly, why does this happen? Surely it'd be better to throw an exception rather than delete all child entities in the list? Secondly, what is the solution to prevent concurrent modification of entities? I understand normal Java synchronization/locking wont work on GAE? Thanks -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Should JDO use be synchronized in threadsafe=true application?
I've been running an application successfully for some time on the app engine. During last week I've couple of times tried enabling threadsafe in my app. It seems to randomly cause issues with retrieving or storing data with JDO. What I see when I start to get these issues is this (I've replaced my apps class names with ---): java.lang.UnsupportedOperationException at org.datanucleus.store.appengine.EntityUtils.getPropertyName(EntityUtils.java:62) at org.datanucleus.store.appengine.DatastoreFieldManager.storeObjectField(DatastoreFieldManager.java:839) at org.datanucleus.store.appengine.DatastoreFieldManager.storeStringField(DatastoreFieldManager.java:474) at org.datanucleus.state.AbstractStateManager.providedStringField(AbstractStateManager.java:1023) at ---.jdoProvideField(VAJDO.java) at ---.jdoProvideFields(VAJDO.java) at org.datanucleus.state.JDOStateManagerImpl.provideFields(JDOStateManagerImpl.java:2715) at org.datanucleus.store.appengine.DatastorePersistenceHandler.insertPreProcess(DatastorePersistenceHandler.java:341) at org.datanucleus.store.appengine.DatastorePersistenceHandler.insertObjects(DatastorePersistenceHandler.java:251) at org.datanucleus.store.appengine.DatastorePersistenceHandler.insertObject(DatastorePersistenceHandler.java:240) at org.datanucleus.state.JDOStateManagerImpl.internalMakePersistent(JDOStateManagerImpl.java:3185) at org.datanucleus.state.JDOStateManagerImpl.makePersistent(JDOStateManagerImpl.java:3161) at org.datanucleus.ObjectManagerImpl.persistObjectInternal(ObjectManagerImpl.java:1298) at org.datanucleus.ObjectManagerImpl.persistObject(ObjectManagerImpl.java:1175) at org.datanucleus.jdo.JDOPersistenceManager.jdoMakePersistent(JDOPersistenceManager.java:669) at org.datanucleus.jdo.JDOPersistenceManager.makePersistent(JDOPersistenceManager.java:694) I've seen the same exception also when calling PersistenceManager.getObjectById(). The call to these methods comes directly from servlet requests. The error doesn't always happen, sometimes (especially for writes) when it starts to happen, it seems to happen to all writes. I've set threadsafe to false in my appengine-web.xml and the error goes away. But especially now knowing the upcoming change in the pricing, I'd like to be able to run my app multithreaded. My question is that is this a bug in the app engine, or should I be synchronizing JDO use in my app in order to run it with threadsafe=true? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi, Don't know if what you do is possible but why don't you just obtain the data that you need from the other application via simple requests to servlets delivering the needed data. By using Java standard object serialization, you can achieve what you need whatever the object class via a unique and single servlet. This way you stick to gae normal practices at minimum effort. regards didier On May 12, 8:30 pm, Ole Spielberg ole.spielb...@gmail.com wrote: Anyone ? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: App engine SDK jars in WEB-INF/lib. Why???
arjan, There are two sides to the App Engine API: the client and the server. The client side (appengine-api.jar) lives entirely in user-land. If you so chose, you could create your own version of these classes. In the end, the client ends up talking to the server through a binary protocol in order to fulfill much of the API. Having this separation means that you can evolve the client and server independently. For example, dev_appserver and prod obviously have two different server backends for the same client API. You can take that one step further and even independently implement your own server if you so chose. It also means that its trivial to do things like test out and even deploy hotfixes for individual applications instead of waiting for full releases.

[appengine-java] Re: App engine SDK jars in WEB-INF/lib. Why???
Just a quick summary, the servlet spec requires that a servlet container such as appengine provider an implementation for a service. Those jars such as servlet- api-2.4.jar are needed at compile time. They are sometimes provided by the servlet container/ engines at run time in a global directory that is found by the container/engine classloader. appengine provides the servlet, jsp implementations for us at runtime. The appengine specific service implementations are also needed at runtime and compile time and are present in the appengine-api-1.0-sdk-ver.jar. They've chosen not to add the latest sdk to the container global classpath, so yes, the application must provide it. That may be an assumption that all builds are not required to be backwards compatible. Note that the application loader is now checking for the sdk version before upload too, so there's a rough check for compatibility in place. I think I had one app that was using 1.3.8 and was no longer able to deploy it with version 1.4.3.

You can take that one step further and even independently implement your own server if you so chose. It also means that its trivial to do things like test out and even deploy hotfixes for individual applications instead of waiting for full releases.

So, google would have to know which one you are using in order to put it for you in your war when you upload it. Hmmm, there are two possible problems with that explanation: 1. Aren't the GAE jars in the war the ones for local simulation and not the actual ones used by the live GAE production servers? 2. Why would Google need to put them into the war when we upload it? Tomcat doesn't add the servlet-api jars to my war when I deploy it to Tomcat, JBoss AS doesn't add the EJB, JPA, etc etc jars to a war being deployed to it, Resin also doesn't do this. In fact, I've never encountered any Java server that required jars for functionality that the server provided to be put into the war. WEB-INF/lib is for extra functionality that the server -does not- provide. If they just use it for detecting the version for which you developed your app, then why not just put that version number in appengine- web.xml? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

This is on our radar but it's not yet supported. Max -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

We don't have anything to announce related to SQL pricing and quotas, but the access for Java apps will be through JDBC.
