Fast transfer of complex objects
I have a Oracle 8.1.7 database that stores data about
approximately 2 M persons. The database has 12 tables for
storing information, such as (stacked/multiple) names and
addresses. I.e., for each person there may be multiple rows in
the TB_NAME and in the TB_ADDRESS tables.
I have a PL/SQL stored procedure that I want to call from Java
via JDBC. The procedure returns between 20 and 200 people’s
data. I.e., it returns 200 rows from the main table and anywhere
between 0 and 20 rows from the other tables per person, for a
typical total of 20 to 1000 rows from each of the other tables.
On the Java side, I want to build object graphs (data binding).
E.g., a person object has an ArrayList of name objects and an
ArrayList of address objects.
My question is how to return this data most efficiently. I can
see the following solutions:
1. 12 result sets (12 out parameters to be accessed as result
sets). (Problem: 1 round trip for each ((OracleCallableStatement)
stmt).getCursor(i)).
2. 1 result set of Struct. (Problem: Have to create objects in
DB.)
3. XML (Problem: Have to create XML document or DOM parse tree.
Have to create objects first.)
4. Arrays (Problem: Arrays are references, lots of round trips.)
5. 1 flat result set (Problem: Cartesian product, de-
multiplication, huge join)
6. Use a Java stored procedure to create the Object graph and
return serialized data as a BLOB. (Problem: I cannot see how
this could be the fastest.)
7. Any others?
Has anyone experimented with this? What is the fastest solution?
What ballpark performance can I expect on 2 processor Intel
class machines?

Martin
Hi Thomas,
You have to log in to the XI system at Unix level where u can find the export and import directories of respective system.
Otherwise ask your basis team to move the required tpz files from the source export directory to the target import directory and specify the path and tpz file names to them.
The basis guy is the best person who can help u..

About serilize/deserilize complex objects
Dear friends,
I have a question about transfering complex objects between client and server. if I just transfer primitive data type, any language of client side can consume this web service. but how about if I transfer complex object?
for example, in the server side, I use java to make a bean--bean1, in this bean, there is a variable bean2, it's also a java bean with primitive variables. though WSDL file, I know the complex data type is mapped to primitive data type at last. but I don't know if the client side can consume this web service if it's made by c language or perl language. also, supposing such kind of client side can consume this web service, can the client side transfer back this bean object to server and server can recognize it?
I really confused about this, from theory, web service is platform indepedent, does it mean language indepedent? or conditionally? does there any samples or articles about it?
any hint will be greatly appreciated!
SammyIt depends on the product and version of CORBA spec you are working with, but you can always pass a reference to the interface of the object in the parameter list, then the code can do whatever it needs to by manipulating the interface.

Problem with some characters in complex objects
Hi all,
I've built a webservice which returns a complex object with several fields inside. All fields are public and accessable via getter and setter methods.
The problem is, that some of these fields contains numbers or underscores in their names.
For example:
public int field_a;
or
public String house3of4;
When I try to import these webservice as a model in a Web Dynpro project, it doesn't work until I remove these characters.
Is this a known problem or is there any solution for it?
Thanks

Data Migration - SSIS Transfer SQL Server Objects Task or something else
Can someone please kindly help me with this.
Scenario
I have a requirement to transfer selected tables and views (with a specific schema) between two databases which reside in two different servers. In the interest of clarity I will call my databases DB_A and DB_B respectively. Please note that these databases
are NOT on the same server.
Transfer of these objects (tables & views) happens once a month. 99% of the objects in question will be of the same name and schema between the two databases as the ones migrated from the previous month. However, metadata definitions may change on DB_A
and those changes are supposed to be reflected on DB_B along with the associated data. This therefore means that each time a transfer/migration happens; objects in DB_B are dropped first and completely replaced by objects from DB_A.
Problem
What is the best way to achieve this?
My first attempt has been a go on the Transfer SQL Server Objects Task
in SSIS. The problem that I have is that when using Transfer SQL Server Objects Task
I don’t know how to filter objects in DB_A so that only objects with a specified schema can be migrated.
Transfer SQL Server Objects Task appears to be the best solution to me to accomplish my requirement but I can’t filter the desired objects by schema. Someone suggested using C# but my C# skills are not that eloquent.
May someone kindly help please, or possibly suggest any other way which can be handy to fulfil my requirements.
Many thanks,
MpumeleloHi Prashanth
Thanks for your response. There is one problem though in my case. I’m sorry I forgot to mention this in the original question. When the objects are moved from BD_A to DB_B the schema in DB_B changes. That is, schemas are not the same between the source and
the destination database. How do I handle that with the solution that you have suggested?
Many thanks,
Mpumelelo -
How to convert an array collection instance to a complex object for interaction with webservice
Hi there,
I have a stubborn problem that I am trying to work out the best way to solve the problem. I am interacting with a WebService via HTTPService calling a method called find(String name) and this returns me a List of ComplexObjects that contain general string and int params and also lists of other Complex Objects. Now using the code:
ArrayCollection newOriginalResultsArray = new ArrayCollection(event.result as Array)
flex converts my complex objects results to an arraycollection so that I can use it in datagrids etc. Now up until this part is all good. My problem is when getting a single instance from the results list, updating it by moving data around in a new datagrid for example - I want to interact with the webservice again to do an create/update. This is where I am having problems - because these webservice methods require the complex object as a parameter - I am struggling to understand how I can convert the array collection instance back to my complex object without iterating over it and casting it back (maybe this is the only way - but I am hoping not).
I am hoping that there is a simple solution that I am missing and that there is some smart cookie out there that could provide me with an answer - or at least somewhere to start looking. I guess if I have no other alternative - maybe I need to get the people who built the service to change it to accept an array - and let them do the conversion.
Any help would be greatly appreciated.
BertHi Bert,
According to my knowledge you can use describeType(Object) method which will return an XML... That XML will contain Properties and values just iterate through the XML and create a new Object.. Probably u can use this method...
public function getObject(reqObj:Object,obj:Object,instanceName:String,name:String=null,index:int=-1):Obj ect
if(!reqObj)
reqObj = new Object();
var classInfo:XML = describeType(obj);
var className:String = instanceName;
if(name!=null)
className=name+"."+className;
if(index!=-1)
className=className+"["+index+"]";
for each (var v:XML in classInfo..accessor)
var attributeName:String=v.@name;
var value:* = obj[attributeName]
var type:String = v.@type;
if(!value)
reqObj[className+"."+attributeName] = value;
else if(type == "mx.collections::ArrayCollection")
for(var i:int=0;i<value.length;i++)
var temp:Object=value.getItemAt(i);
getReqObject(reqObj,temp,attributeName,className,i);
else if(type == "String" || type == "Number" || type == "int" || type == "Boolean")
reqObj[ className+"."+attributeName] = value;
else if (type == "Object")
for (var p:String in value)
reqObj[ className+"."+attributeName+"."+p] = value[p];
else
getReqObject(reqObj,value,attributeName,className);
return reqObj;

Complex object as parameter from BPEL PM to Web Service
Hello,
I'm having a problem with being able to invoke a method on my web service from BPEL PM. It's a 'create' method, so I'm sending a complex object as the input parameter of the method.
I'm encountering the same kind of problems I have at different stages in the project I'm on: SOA works really well as long as you don't use complex objects. As soon as you do, SimpleDeserializer exceptions seem to be thrown all over the place. In this case, the error I'm getting is:

The WSDL is at:
http://covarm.tvu.ac.uk/validationEvent/wsdl/validationEventSOAP.wsdl
I'm invoking the 'createEvent' method. I know the service works okay because I've tested it with Rational Software Architect and Eclipse's Web Services Explorer, and also with standalone code and JUnit tests.
The problem seems to be getting the mapping from BPEL PM to the Web Service. I'm sending the object as a message type that's defined in the WSDL of the service:
<xsd:element name="createEventRequest" type="tns:event" />
- <xsd:complexType name="event">
- <xsd:sequence>
<xsd:element name="event-detail" type="tns:event-detail" />

<xsd:element name="minute" type="xsd:string" />
<xsd:element name="feedback-list" type="tns:feedback-list" />
</xsd:sequence>
</xsd:complexType>
Is this something that's
a) fixable?
b) workaroundable?
c) a known issue?

Is there any way to activate the keep identity setting when using a Transfer SQL Server Object Task?
Is there any way to add the "Keep Identity" option to the tables selected for transfer in a Transfer SQL Server Object Task? It seems that would be very useful, yet I can't find an easily available setting for it. I would prefer to
accomplish this within the Transfer SQL Server Object Task since it can copy any new fields added to the source tables, as opposed to having to rebuild a custom Data Flow Task any time a table structure is altered. I thought setting "CopyPrimaryKeys"
to True would do the trick, but I found that only ensures that the column settings are transferred; when the transfer happens, the destination id column is populated based on the specified seed and increment value, not what's actually in the source table.
I'd like to point out that replication isn't really an option here. This is a package that runs a few times a day to keep some data on our website up to date with data in our protected corporate environment.IIRW there is FastLoadKeepIdentity specifies
whether to keep an identity in OLEDB destination

I have created a complex object by building it on a page, select all, then grouping the objects. Then I place several of these objects on the same page. If I need to ungroup one of these complex objects to make a change, I need to make dozens of clicks to select all of the elements again for regrouping, Is there an efficient way to re select all of the elements that are making up one of my complex opjects?
Thanks,
KenKen,
Usually it's possible to Click-Drag a Selection Rectangle to affect several elements at once. How easy this is depends on the layout and proximity to things you don't want to select. Sometimes to Click-Drag, we must begin in the Margin and also hold down the Command Key. If you get more objects selected than you intended, you can cancel the selection of individual items with a Command-Click.

Thanks in advance,
SanjayThanks for the quick reply.Actually the web service is already deployed on the server.What I want to do is use existing wsdl file of the deployed web service and invoke the method of the same using oracle PM.
If I remove element which uses apachesoap:Map type it just works fine also I am getting the complex object returned by the web service method.But when I try to set appDataDef which is of type apachesoap:Map(Axis conversion for java.util.Map and it uses namespace xmlns:apachesoap="http://xml.apache.org/xml-soap") I am getting the error.
Can you give me some direction to use this exising wsdl file to set map object or it is not possible. -
Passing complex object from JavaScript to Flex
Is it possible to call a Flex function (defined with ExternalInterface.addCallback) and pass a complex object from Javascript? The properties of the object are all simple types, but the object itself is an array of objects. For example:

var arrayOfObj = [ { one: "one", two: 2, three: "blah" }, { one: "xyz", two: "abc", three: 3.141 } ];
callSomeFunctionInFlex(arrayOfObj);
</script>
What would I do on the Flex side to make this happen?Complex object passing works as expected in Blazeds.
There are certain cases where you need to write custom bean proxy classes to marshall an object, but your case is very simple and will not require it.
Make sure that you set the full java package and class name in your remote alias statement on your client value object. The class has to be fully qualified. The AS value object also needs the correct import of the nested value object or you will get a compile error.
Make sure that the blazeds server has the full class path set to your java objects.
To debug, you can turn on Blazeds logging in the services-config.xml file like this:
<logging>
<!-- You may also use flex.messaging.log.ServletLogTarget -->
<target class="flex.messaging.log.ConsoleTarget" level="DEBUG">
<properties>
<prefix>[BlazeDS]</prefix>
<includeDate>false</includeDate>
<includeTime>false</includeTime>
<includeLevel>true</includeLevel>
<includeCategory>false</includeCategory>
</properties>
</target>
</logging> -
Hi, all.
First, I want to construct a fast transfer stream by programming not using the export item's stream and to import the stream to the folder by posting import request in EWS.
So, I export the item by EWS and investigate the exporting stream's struct by reading the [MS-OXCFXICS].pdf. And I can parse each MAPI property, marker, meta-property from the stream.
I find that the stream is made of many pages, most page's length is 0x7BC0, some are less then 0x7BC0. And in the previous section of the stream, there are some configurations. So the questions are:
1. What is the paging rule? or What is the principle of the paging? Whether a complete propvalue/marker(ref from [MS-OXCFXICS].pdf) must be contained in a page except some binary type?
2. Why the page's binary length is 0x7BC0? Or where is the configuation about paging length?
3. The stream is made of the FXOpcodes and the subbuffer about the FXOpcodes, and I find the mean of the FXOpcodes:
internal enum FxOpcodes
None = 0,
Config = 1,
TransferBuffer = 2,
IsInterfaceOk = 3,
TellPartnerVersion = 4,
StartMdbEventsImport = 11,
FinishMdbEventsImport = 12,
AddMdbEvents = 13,
SetWatermarks = 14,
SetReceiveFolder = 15,
SetPerUser = 0x10,
SetProps = 0x11
and in the stream there are 4 part(after I parse the stream):
A. OpCode:Config, value:0000000001000000
B. OpCode:IsInterfaceOk, value:010000000703020000000000C00000000000004600240080
C. OpCode:TellPartnerVersion, value:000F91838417
D and follows is: OpCode:TransferBuffer, Count:31680
So
a. What is the OpCode:Config value meaning?
b. Some parts of The OpCode:IsInterfaceOk' value is the IID_IMessage("00020307-0000-0000-C000-000000000046"), What is other parts meaning?
Thanks in advance for any ideas.Hi Haiyang,
Your questions are not covered by the Open Specification documentation and this is documented in [MS-OXWSBTRF] — v20141018 section “1.3 Overview”.
The upload and export data stream is an opaque format that only needs to be understood by a server implementation. The client only serves as a repository for the opaque data stream so that it can be uploaded to the server at
a later time.
You made good progress in interpreting the buffer using other documents. Why do you need to be able to parse the data? Please describe your project in details and I might submit a suggestion to document the layout of the data stream,
if your project justifies it. You can send the description directly to me.
Thanks, Vilmos -

Thanks in advance for any ideas.OK. Thank you.
Today I build a stream with a paging rule as below:
1. Keep each page's byte length is 31680.
2. Make sure a complete property value in a page except binary type property whose value length is larger
than 31680.
And it can work very well when import the stream to the folder by EWS. -
Web Service Request Collection/Complex Objects doesn't work
I am unable to call a .net web service using Adobe LiveCycle Designer 8.0. My test web service accepts either a complex object or a collection of the same object.
EX)
[WebMethod]
public string CostChange(CostChangeNotificationItem change1, CostChangeNotificationItem change2)
return "Success";
[WebMethod]
public string CostChangeColl(CostChangeNotificationCol changes)
return "Success";
I can successfullly create the connection to the web service. When i drag and drop the connection request/button/and response onto the designer i can call the web service successfully.
However you never see the request objects on the form unless you change the subforms to flowed and the min and initial count of the object to 1. When this is done the web service never gets called. You can click the button until you are blue in the face with no successful call.Hello ,
our problem was a result of a corrupt database. Please check the Log files in CUCM . have a look for "missed table entries "
cli
utils dbreplication repair
check logs again the path to the log is displayed after the repair.
hope it helps
good luck -
Flex 4 - Complex objects in a web service response are null
I'm using a web service (imported by the data services tool) that returns an array of objects. The service returns the array just fine, except the objects aren't being created correctly.
The objects (we'll call them CPs for now) contain some strings, an int, and 3 other complex objects. The basic fields (strings, ints, booleans) show up just fine, but the complex objects all show up as null.
The web service is working properly, and I can see that the response it's getting is correct.
If anybody has any help regarding this issue, I'd greatly appreciate it.
Thanks!There should be classes generated by the tool that map to the types in the
WSDL, and then the actual webservice response has to match the types in the
WSDL. If there is some discrepancy, the conversion will not happen
correctly.
Also, the generated classes must be linked into the SWF. If you comment
them out of your code somehow, then they won't be available for the
conversion. Generate a link-report and make sure they are in.
You might also have trouble if you do not use the generated WebService and
go directly to mx:WebService. -
Web Services with Complex Objects (Urgent !!)
Hi,
My last post was on a problem using IBM-RAD (Service) and AXIS2 (Client) in "New to Java" Forum. That is one of the trial scenarios I'm working on nowadays. Hope, I'll get some useful reply soon.
Now, I need a suggestion about the application I'm working upon. It is as follows:
(i) The application (i.e. Service Class) takes some primitive,String and/or some bean object as input
(ii) It returns a bean object [or an array (can use collection class also if possible) of bean objects].
(iii) The bean properties are primitive,String , other bean objects, and/or some collection object(Vector / ArrayList etc.) i.e. it should handle complex objects.
(iv) The Service should run on Websphere and Client on Tomcat.
A pictorial representation is given below:
[primitive/String/bean object (Input arg)]
[(Contains primitive/String/other bean objects/collection class)] Bean <---------> Service <----------------------- Client
[Calls bean] |===============> Client
[Returns bean (or array of beans / collection object)]
I'm now trying (by building test applications) a combination of IBM-RAD (Service) and AXIS2 (Client), but facing problems in handling array of beans and/or collection classes either on Service or on the Client side.
So, I need some suggestions on whether I'm going the right way, or need to change my approach (or technology). Any suggestion would be appreciated.
Please reply ASAP, it is urgent.
Thanks in advance,
Sumanno problem for me, so it's not urgent.
