[flexcoders] Hibernate..
Hi, I would like to know for large scale application which one is better using HibernateAssembler or SQLAssembler in data-management-config.xml. Thanks in advance.
RE: [flexcoders] Hibernate..
If you have an existing server-side domain model and are using Hibernate use the HibernateAssembler. If you don't have any current server-side code and just want to expose some tables in your database to clients use the SQLAssembler. It really comes down to whether it makes sense for your client app to be interacting with database tables directly, or whether you need be interacting with server-side Java classes. Hope that helps, Seth From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of pradhasan Sent: Friday, January 18, 2008 8:41 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Hibernate..

[flexcoders] Hibernate conflict problem
I have a conflict problem with my application using hibernate with version columns. I apply this workaround : http://www.mail-archive.com/flexcoders@yahoogroups.com/msg39026.html (adding update-conflict-modeNONE/update-conflict-mode In my data-management-config.xml file, but it did nothing! I have the conflict error anyway, and with a break point on the server I found that its a DataSyncException on a version property. so it looks like the bug described in the mail, but changing the config file do nothing. why? Maybe I'm using a buged version of flex. Can somebody help me contact this Jeff man who wrote this mail please? Manu

[flexcoders] Hibernate AnnotationConfigurations
Does anyone know if the FDS built-in HibernateAssembler can use annotations in the Java classes rather than the hbm.xml files? If we do not have to generate/manage hbm.xml files from our annotated classes all the better! Thanks, Kevin
[flexcoders] Hibernate MiddlegenIDE Plugin Install
Has anyone used 'middlegenide' with Ecplise to generate Hibernate Mapping files? http://sourceforge.net/project/showfiles.php?group_id=36044 Seems like this would be an easy way to map an existing database to Hibernate for use in FDS. Seems better than Hibernate-tools which doesn't support reverse engineering of foreign keys. However, I can't for the life of me figure out how to install this plug-in! I have never installed a plug-in in Eclipse without using the Find Install feature. Anyone know how to install this? - Kevin
[flexcoders] Hibernate Transactions Roles
I am trying to build a Hibernate enabled app (with Flex Data Services) but I am wondering how do deal with certain requirements of my app. For example, I employ a root object table which contains all ids (and some admin vars) for every table in my app. Every data table has a one-to-one relationship with this root table and thus every insert includes a transactional update of both the data table the root object table. Is this something that can be done easily with FDS Hibernate while still be able to use the simple 'commit' command on the client side? My other questions is how I can check certain user roles before performing database operations? For example, if the client tries to do a DataServices commit to the database and that logged in user does not have the proper user role to do that operation, the request will be rejected at the server. I love how simple the DataServices functions are, but does that mean that it is hard to add functionality to these low level operations? I currently am successfully using PHP to manage my database on the server (using AMFPHP). The main reason I would like to switch to Java/Hibernate is to take advantage of data pushing which could be very useful for my use case. To my knowledge there is not a way to do this with PHP. I hate to switch everything over if I don't have to, but...for what I gain it might be worth it. Thanks for the the help. There is very little documentation that I can find on customizing DataServices/Hibernate's integration with Flex... - Kevin
[flexcoders] Hibernate error:java.lang.NoSuchMethodError:org.hibernate.Session.getTransaction
Hi - I'm new to Flex. I'm trying to move an existing Java Hibernate application over to have a fully Flex front end. The first thing I'm trying to do is get access to all my database objects through the Hibernate Assembler. I've got my Java code loading, the destination set up, etc, following the example app at http://blogs.adobe.com/mtg/2006/08/my_first_hibernate_enabled_fle.html I've replaced the code in the sample app where necessary to point to my own database object. When I start the app, I get the following error in the server console: Throwable in RtmpReader thread: java.lang.NoSuchMethodError: org.hibernate.Session.getTransaction()Lorg/hibernate/Transaction; java.lang.NoSuchMethodError:org.hibernate.Session.getTransaction()Lorg/hibernat e/Transaction; at flex.data.assemblers.HibernateManager.getSession(HibernateManager.jav a:97) at flex.data.assemblers.HibernateAssembler.fill(HibernateAssembler.java: 339) at flex.data.adapters.JavaAdapter.invokeFillOperation(JavaAdapter.java:7 48) at flex.data.adapters.JavaAdapter.invoke(JavaAdapter.java:198) at flex.messaging.services.MessageService.serviceMessage(MessageService. java:139) at flex.data.DataService.serviceMessage(DataService.java:309) at flex.messaging.MessageBroker.routeMessageToService(MessageBroker.java :548) at flex.messaging.endpoints.AbstractEndpoint.serviceMessage(AbstractEndp oint.java:302) at flex.messaging.endpoints.rtmp.AbstractRTMPServer.dispatchMessage(Abst ractRTMPServer.java:682) at flex.messaging.endpoints.rtmp.NIORTMPConnection$RTMPReader.run(NIORTM PConnection.java:665) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Wor ker.runTask(ThreadPoolExecutor.java:665) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Wor ker.run(ThreadPoolExecutor.java:690) at java.lang.Thread.run(Thread.java:595) and I catch ClientError:DeliveryInDoubt fault at the same time.

[flexcoders] hibernate + cusome querries
Could some one show me an example of how I can run custom queries with hibernate from flex.
[flexcoders] hibernate + many-to-many + inserting records
At this point, I have hibernate working with a many-to-many relationship Here is what I have User Table - one-to-many - user_roles Table - many-to-one - roles table The retrieval of the records works fine. I can also modify and insert the records with no hassle. But my problems come when I need to insert a relationship ( a record into the user_roles table ). The Hibernate generated code only has classes for the other 2 tables, it manages the middle table on its own. Could someone please point me into the right direction as to how that should be done.
Re: [flexcoders] hibernate + many-to-many + inserting records
Hi, I'm still struggling with a many-to-many example that I'm creating, but seeing what I've done so far may be helpful to you. My .java and .hbm.xml files were auto-created using HibernateTools (with a few tweaks) and contain files for the middle table. While I don't know Hibernate very well, I assume that HibernateTools knows what it is doing, so I assume that this code is correct. (?) You can find the entire zipped project here: http://www.brightworks.com/technology/tech_questions/hibernate_lazy_associations/Bw_005.zip And here's the thread on the problems I'm having with it: http://tech.groups.yahoo.com/group/flexcoders/message/58833 Also, this blog post by Victor Rubba may be helpful: http://viconflex.blogspot.com/2006/12/many-to-many-using-fds-hibernate.html Finally, my Flex with Java page might be of some interest: http://www.brightworks.com/technology/adobe_flex/with_java.html Good luck! When you find a solution, please consider blogging about it. :-) Douglas - Douglas McCarroll CairngormDocs.org Webmaster http://www.CairngormDocs.org Flex Developer http://www.brightworks.com 617.459.3840 - michalzak81 wrote: At this point, I have hibernate working with a many-to-many relationship Here is what I have User Table - one-to-many - user_roles Table - many-to-one - roles table The retrieval of the records works fine.

[flexcoders] Hibernate adapter: No channels are available for use
I'm trying to get the hibernate adapter to work with fds by testing out
2 tables from my database.
The two tables represent the make and model of a car.
Hibernate and fds seem to start up fine, the *.hbm.xml files are found but
I receive the following message.
Error: No Channels are available for use.
Anyone have any pointers? or is there a working example of how to use
fds with hibernate?

RE: [flexcoders] Hibernate
Ryan, I'd suggest that you post some of your hibernate code here [1] with the same question. You'll get a lot better Hibernate support there. That said, one important thing to keep in mind from the Flex perspective is your service interface. You should design the integration point as a course-grained service that does as much work on the server as possible (instead of lots and lots of service calls, wrap all that logic behind one clean service point). This is a fairly well known pattern for web services. I have seen services before that exposed lots of CRUD/database operations that don't provide a clean layering in the application and caused serious pain when integrating with Flex (imagine lots of synchronous calls... possible, but painful). hope that helps, ~harris [1] http://forum.hibernate.org/ --- Ryan Scott Jones [EMAIL PROTECTED] wrote: Hi Steve, Thanks for the help.

[flexcoders] Hibernate
Apologies if this has been covered already ... Does anyone know of an in depth tutorial on integrating Hibernate and Flex? Have people been using Hibernate successfully with Flex? I'm about a week into creating an application and it's doing my head in. Flat objects work just fine for me, but anything deeper than that (e.g., objects containing arrays of objects) just hangs on the RPC call, even with lazy=false. I'm sure I'm doing something stupid, I just haven't been able to diagnose what that stupid thing I'm doing is. I read the ONJava article: http://www.onjava.com/pub/a/onjava/2004/12/01/flexjava.html?page=1 and thought it was rather brief. If anyone knows of anything more detailed, I'd love to read it. Thanks!
