FDS and Hibernate dynamic mapping

I am using FDS with hibernate
(flex.data.assemblers.HibernateAssembler) to transfer data between
the flex client and my JDBC database. This works really smooth, as
long as I specify a server-side java class (POJO) in the
<hibernate-mapping><class name="some.class"> attribute.
As I dont really need these server-side java classes for
anything else, I have tried to save some work by using the
hibernate "dynamic-map" mode (<hibernate-mapping><class
entity-name="some.entity">). But in this case, FDS does not map
the result to the corresponding flex ActionScript class with the
correct RemoteClass alias. The DataService "fill" method returns an
ArrayCollection of "ManagedObjectProxy" items containing the field
"$type$=some.entity" instead.
Does FDS support hibernate dynamic mapping? Is there a
workaround for this problem?

Hi Per,
The Hibernate assembler doesn't currently support the
dynamic-map mode, so for now you'll need your POJOs.
Best,

Parent Child Hierarchy with FDS and Hibernate

I know my chances of getting heard here are slim, but I am at
a dead end, so here goes.
I have a four level hierarchy of objects
PlanPoint
....UserScenario
........Scenario
............Competitor
which have bi-directional one-to-many relationships between
them.
I have made sure that my hibernate mappings and FDS
destination are matched and I definitely need to have managed
associations as the graph of objects will grow large in my
application (and besides, it is good development practice). So I
have a fully formed project (or at least I think I do) and I get a
duplicate object error.
Right at the bottom I have an alternative that I have tried
which gives a different error.
Here is a snippet from my log... it picks up just after the

Hi,
thanks for the reply it was very helpful. I came to pretty
much the same conclusion and started on the path of a re-write of
the hibernate assembler myself. As far as I can tell the Hibernate
Assembler is a Java Assembler, so there didn't seem much difference
to me between fixing that one and writing another one. Adobe ship
the code.
Bit of a cheeky request, but I don't suppose you would be
willing to share your assembler layer so I have a template against
which to work? Biggest problem with this sort of activity is a lack
of examples which makes it very slow going and largely trial and
error.
If you would like to know more about our application I will
provide contact details so we can discuss.
Simon
PS Jeff Vroom posted a reply saying that the Adobe Hibernate
Assembler didn't work properly with hierarchical data (which I
imagine is every real application in the world), personally I think
Adobe should fix it or pull it.

Hibernate creating Dynamic Mapping File

Hi All,
I am supposed to create the Mapping Hbm file dynamically at run time. I learnt that this can be acheived from a Java class file using Xdoclets. But in my case i have to do it from a Xml File. Can this done by xdoclets or anything else?
Parsing the xml file and creating the Mapping file would be a good Idea. Is there is any way?
Thanks
Aski

See the First Xml File will have the Requirement Data, It will be on a bunch and it may reside on some other schema. And the Second Xml will be our Mapping Xml File which should be reside on Hibernate standards.
So which will be the best way to transform from one file(xml) to other Xml File(Mapping.xml).
Thanks

Dynamic mapping: I have no Class. I want to get database columns into a map

I want to practice dynamic mapping.
I don't know the class in development time. I know the attributes only on runtime. Then I create the table, and want to practice OR Mapping to get and set data in this table while all I have is aa map of fields (Strings/int for direct-to-field mappings, Lists, Objects, etc.) - against this new table.
I have no Class. Neither source nor Class object in hand.
In Hibernate it is possible and very well documented. It's called "Dynamic Model". I have to get a special Hib session from a session i already have, and it starts to work with Maps and not real classes and objects.
Here is the command in Hib: sess.getSession(EntityMode.MAP);
Thanks in advance.
Doron

Doron,
We have been working with dynamic models and byte code weaving for a while now. I took some work I did a few months back now and upgraded it to work with EclipseLink JPA. I have started creating an example within EclipseLink to both illustrate how EclipseLink can be extended to deliver this dynamic mapping and also to start consolidating our existing dynamic support in our SDO and DBWS components into a more general solution that be used out of the box with JPA.
I have started a wiki page to illustrate how this functionality can be used. Take a look and let me know if this might address your requirements.

Transfer Object in JSF, Spring, and Hibernate

The application on which I am working deploys the JavaServer Faces, Spring and Hibernate frameworks.
We are going to use the "transfer object" to move data between J2EE tiers from the front end to the back end and vice versa. In addition, data "types" may need to be converted --
At the front end, the "type" of the data that are entered by users may not match that in the database table. For example, checkboxes may be marked or left blank by users. The "type" of the checkboxes is "boolean" in the JSF backing bean. However, we have either "Y" or "N" for the corresponding field in the database table.
The JSF backing bean holds data as well as controller functionality. Of course, the transfer object holds data only.
With regard to class properties, Is the transfer object an exact copy of the JSF backing bean? And at which tier the data are converted to match their correspoding "types" in the database tables?
We also have the "data objects" which are exact representation of database tables.
Thanks for your advices.

Small example: you can decide in the business layer
whether to convert it to boolean or Boolean (which
has a 3rd state: null).But it all goes back to your data model. If your data model supports null for that property, then of course boolean is a poor choice. If that case one could use Boolean. None of this has anything to do with re-usability, which was your objection.
I think the re-usability question goes back to the data model as well. Suppose your data model says this property is boolean valued. However if your database does not support booleans natively, then you need to map the value for storage in the database. But that is the data persistence layers problem.
OTOH, suppose your data model says that this property may be 'Y' or 'N'. Then the Java class represent the business object should not have a boolean property, we should make it match the data model.
However, I think that most cases where people are storing 'Y' or 'N' in a field in the database fall into the first case, where the data model is a boolean and they are working around limitations in the database. There is no reason in that case to perpetuate the same limitations in the Java code.

RE: Dynamically mapping data to widgets

One quick and dirty solution would be something like this (though not
terribly efficient):
newPanel : Panel;
newPanel = <panelCreatedFromWindowWorkshop>.Clone(deep = TRUE);for childWidget in newPanel.children do
-- check if the childWidget field name matches field name to be
set
if childWidget.name.isEqual(source=<..FieldNameToSet..>,
ignoreCase=TRUE) then
dataWidget : dataField = dataField(childWidget);
if dataWidget.textvalue = NIL then
dataWidget.textvalue = new;
end if;
-- set the textvalue of the childWidget to required
value
dataWidget.textvalue.setvalue('WORKS !');
end if;
end for;
Your problem would have been directly solved if the Forte library class
CompoundField provided a SetDataObject( ) method corresponding to the
GetDataObject( ) method.
According to Forte Help - "The GetDataObject method returns the object
that the compound field is mapped to. If the compound field is not
mapped to an object, this method returns NIL."
Maybe Forte could consider providing this in a future release.
Another option would have been to use the GetFieldByName( ) method on
the newly created panel to get at the child widgets directly.
According to Forte help - "GetFieldByName is designed for use in dynamic
applications. For example, you can use GetFieldByName to retrieve the
names of dynamically created fields for immediate use in dynamic
applications."
This works fine for compile-time named widgets, but I couldn't get it to
work for the newPanel child widgets using the code below, or maybe I am
missing something here.
newPanel : Panel;
newPanel = <panelCreatedFromWindowWorkshop>.Clone(deep = TRUE);newPanel.name.setvalue('newPanel');
newPanel.parent = <aGridField>;
dataWidget : dataField = dataField(newPanel.getFieldByName('age'));
(OR)
dataWidget : dataField =
dataField(<aGridField>.getFieldByName('newPanel.age'));
(OR)
dataWidget : dataField =
dataField(self.window.getFieldByName('newPanel.age'));
In all cases the return value was NIL.
Maybe someone from Forte could shed more light on this.
Hope this helps.
Prashant.

// tada! "something" appears in a data field of the original panel

Dynamic mapping in BizTalk orchestration using BRE

Hi,
I want to do a transformation dynamically based on the schema type (document strong name). In one of the thread, I saw a solution for a similar problem, but in which an additional field was needed to be added to the schema to hold the map name. In my scenario,
i will not be able to add the additional field to the schema.
Can you please suggest an approach where I can set my map name in the BRE (based on the document strong name and retrieve the map name in the orchestration.
Regards,
Ujjwal
-Ujjwal

Have you considered " BRE Pipeline Framework", I know some of the BizTalk project uses it and it quite good. I don't want to duplicate this forum with how this works as
the details are already available online. Find the following reference on how this can be used with BRE and in what use cases this can be really helpful. Hope this helps.
Using the BRE Pipeline Framework to execute maps dynamically
Also Paolo Salvatori's component is also quite popular on this context, but this doesn't directly implement using BRE.
But this just for your reference.

Dynamic mapping using xslt

I have question regarding XSLT map. I saw xslt is embedded as part of map dll. Now I have case like different vendors are sending me files in different structure . Let me clear here all my input is EDI files.
Example one vendor is sending HL segment at header level and one at detail level. Other vendor send only at header level . So surely my map logic is different .
So I was thinking create XSLT for each vendor and load dynamically based on ISA Id and GSId. Is it possible that load xslt dynamically something like this?
If(ISAId == "sender1" && GSId ="sender1)
//code to load map dll
map1.LoadXslt(sender1xslt).
What is better way to handle this case . I am not considering to create at receive location as I will get data from AS2 and I will have only one receive location.
What is better approach for this? Do I need to create separate map for each TP and load it?
Please let me what is better approach in this case?

I tried one small sample with keeping map name in config file as
<add key="Map1" value="DynamicMap.OrdMap,DynamicMap, Version=1.0.0.0, Culture=neutral, PublicKeyToken=51b3a99d8425ff5a"/>
<add key="Map2" value="DynamicMap.OrdMap2,DynamicMap, Version=1.0.0.0, Culture=neutral, PublicKeyToken=51b3a99d8425ff5a"/>
then in orchestration have
expression shape with
MapName = System.Configuration.ConfigurationManager.AppSettings["Map1"];
MyMapType = System.Type.GetType(MapName);
Then messageassignment shape with
transform(OutMsg) = MapName(InMsg);
When I test it get following error with message get suspended

Dynamic mapping for alv

Hi All,
I need to display three tables using alv.
i have used one alv component in my application.
In my context i have three nodes ( for three tables )
when i am trying to map one node of my component control to 'DATA' of alv component
its working fine. i am getting the data of one table .
Now , my problem is for the remainig two tables . how these two nodes are mapped for the same alv 'DATA' attribute of alv component.
Whether i need to create two more alv components or Is there any possible to dynamic mapping ?
Thanks and Regards,
sravan.

Hi Sravan,
Now , my problem is for the remainig two tables . how these two nodes are mapped for the same alv 'DATA' attribute of alv component
You cann't map the multiple context nodes to the DATA node of interface controller.You have to declare 3 component usages.
or
you want to set the map the dynamically then use this code.
data:l_ref_interfacecontroller type ref to iwci_salv_wd_table.
l_ref_interfacecontroller = wd_this->wd_cpifc_alv( ).
l_ref_interfacecontroller->set_data( lo_node ).

Add Image to Jasper Report with Struts 2 and Hibernate

Hi I want to add image to jasper report[pdf] in the environment of Struts 2 framework and hibernate. I am trying
this for last couple of days, but i am unable to get the work done. if any body know the steps to add image to
jasper reports, please help me or if u have any tutorials please let me know. I am using iReport-nb-3.5.0 to generate jasper files.
Thanks in advance

Finally i found a way to add image to jasper report. It is pretty simple, just give the exact image location to the image expression. In your web application, the image location may vary so, dynamically set the image location from your model class. Also, make sure that your lib folder contains itext-1.3.1.jar. If your lib folder contains itext-1.3.1.jar and iText-2.1.3.jar u will get like: java.lang.NoSuchMethodError: com.lowagie.text.Image.plainWidth()F
So remove the iText-2.1.3.jar and keep only itext-1.3.1.jar, try this will work

Elements 11 vs 13: how can I add a new place tag to my PSE13 database without using the wretched and totally inadequate map technology that Elements 13 wants to impose.

HI,
I have recently installed Elements 13 having used Elements 11.0 successfully to build a database of 30,000 plus images indexed by place, people, and photo date. Elements 11 allowed me to add new places which are meaningful to me but which are a complete mystery to the mapping technology of Elements 13. For example some years ago I lived in London in a road called Argyle Road. In elements 11 I could enter the place tag as Argyle Road. In Elements 13 I am required to locate Argyle Road on the map, but the map presupposes that the Argyle Road I am referring to is in Ealing in West London. It is not!
I now live in a place called Broadsands but the Elements 13 Map places this 0.5 miles away from what I would describe as Broadsands.
So the question: how can I add a new place tag to my database without using the wretched and totally inadequate map technology that Elements 13 wants to impose.

Thank you for your quick response, BalusC. I really appreciate your answer.
Yes, you are right. If I manually code the same amount of those components in the JSF pages instead of generating them dynamically, the server will still run out of memory. That is to say, JSF pages might not accommodate a great deal of concurrent visiting. If I upgrade the server to just allow 1,000 teachers making their own test papers at the same time, but when over 2,000 students take the same questionnaire simultaneously, the server will need another upgrading. So I have to do what you have told me, using JS+DOM instead of upgrading the server endlessly.
Best Regards, Ailsa

What are the relation between JPA and Hibernate, JPA and TopLink?

What are the relation between JPA and Hibernate, JPA and TopLink?
Can JPA instead of Hibernate and TopLink?

The Java Persistence API (JPA) is the object relational mapping persistence
standard for Java. Hibernate and TopLink provide an Open source Object-relational mapping framework for Java.
They provide an implementation for the Java Persistence API. In my opinion, both Hibernate and TopLink provide support to JPA
and they can also be regarded as the complementary to JPA.
Let's wait to see other person's opinions.

How to give dynamically mapping in interface

Hi all,
I have requirement for this requirement i am thinking various scenarios,
could please tell me is there any way to we can give source,target data stores and mapping dynamically(execution time) to the interfaces ? if it is possible then i can re use job again and again ?
please give your solutions for this post
Thanks,
Surya.

Please let me know if I miss the mark here.
If you are trying to build the 150 interfaces without spending the time to do so manually, use the ODI SDK. Check out David Allan's blog post for examples here https://blogs.oracle.com/warehousebuilder/entry/odi_11g_interface_builder. You can build your interfaces once - without need for dynamic mapping at execution time.
I'm pretty sure there is no good way in ODI "out of the box" to dynamically map columns at execution time, but I imagine you could use the ODI SDK to write a Java program that does so. Then, use the Open Tools feature in ODI to run the Java program within your ODI processes. I'm not sure the value of this, but I do not have a full understanding of your requirement.
I hope this helps. Enjoy!
