Soap and deserialize objects

Hello,
problem:
I'am trying to get a connection between a java soap client and a perl soap server. There's no problem with that for "simple data types" (like String) for return values but i need to get an object back from the server ... so theres no deserializer found for that object.
question:
it is possible to deserialize an object from a perl soap server in a java client ?
how can i do it ?
thanks and greets
guen

Using serialize and deserialize methods generated by clientgen

I am trying to use the classes generated by the weblogic.webservice.clientgen tool
from the weblogic 8.1 release. I would like to be able to make direct use of
the serialize and
deserialize methods in the "Codec" classes that correspond to the various request
and
response object classes. However, these methods require SerializationContext
and
deserializationContext objects as inputs. Are these context objects things I
can construct,
manufacture and/or access? Are there any coding examples for using these methods?
Thanks.
Michael

Bruce,
Thanks for the response. I have seen the documentation before. What that shows
me is how
to write customized Serialize and Deserialize methods. What I want to do is call
the ones that
clientgen has already created for me. I would love to have these called by the
internals of the
generated code as part of the handling of service calls. My problem is that the
web site
that I'm calling for these services uses SSL, and every attempt to use the clientgen-generated
services results in the following exception being raised:
javax.net.ssl.SSLKeyException: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable
certificate was received.
Since I am successful in making SOAP calls to this same site -- certificate aren't
an issue
for these SOAP calls -- I thought that what I should try is to make the service
calls myself
using SOAP, but to use the generated Serialize and Deserialize methods
to create the request body and process the response body surrounding the SOAP
call.
However, what I'd really like to do
is figure out the cause of the SSLKeyException, and to make the service calls
the way weblogic
intended them to be made. So if you have any suggestions about what might
be causing the exception, I'd appreciate the help.
BTW. In addition to being able to make SOAP calls myself, I've also had some success
making
web service calls using code generated by Apache AXIS's wsdl2java tool and JWSDP's
wscompile
tool; however, neither of these wsdl processors are replacements for clientgen
because they
both have problems dealing with the complex structures described by wsdl files
for the web
services I'm trying to use.

Hi Michael,
The De/SerializationContext are internal/private objects. The example
in the doc (you have probably already seen) is a good starting point:

Explicity mapping between ActionScript and Java objects for the BlazeDS Messaging Service

The BlazeDS documentation shows how to explicitly map between ActionScript and Java objects. For example, this works fine for RPC services, e.g.
import flash.utils.IExternalizable;
import flash.utils.IDataInput;
import flash.utils.IDataOutput;
[Bindable]
[RemoteClass(alias="javaclass.User")]
public class User implements IExternalizable {
        public var id : String;
        public var secret : String;
        public function User() {
        public function readExternal(input : IDataInput) : void {
                id = input.readObject() as String;
        public function writeExternal(output : IDataOutput) : void {
                output.writeObject(id);
and
import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;
public class User implements Externalizable {
    protected String id;
    protected String secret;
    public String getId() {
        return id;
    public void setId(String id) {
        this.id = id;
    public String getSecret() {
        return secret;
    public void setSecret(String secret) {
        this.secret = secret;
    public void readExternal(ObjectInput in) throws IOException,
                ClassNotFoundException {
        id = (String) in.readObject();
    public void writeExternal(ObjectOutput out) throws IOException {
        out.writeObject(id);
If I called an RPC service that returns a User, the secret is not sent over the wire. Is it also possible to do this for the messaging service? That is, if I create a custom messaging adapter and use the function below, can I also prevent secret from being sent?
MessageBroker messageBroker = MessageBroker.getMessageBroker(null);
AsyncMessage message = new AsyncMessage();
message.setDestination("MyMessagingService");
message.setClientId(UUIDUtils.createUUID());
message.setMessageId(UUIDUtils.createUUID());
User user = new User();
user.setId("id");
user.setSecret("secret");
message.setBody(user);
messageBroker.routeMessageToService(message, null);

Hi Martin. The way that AMF serialization/deserialization works for BlazeDS is the same regardless of which service is being used, so yes that code will work for messaging as well. On the server, the serialization/deserialization of messages happens at the endpoint. For an incoming message for example, the endpoint deserializes the message and then hands it off to the MessageBroker which decides which service/destination to deliver the message to.
That was a good question. Thanks for asking it. Lots of people are used to doing custom serialization/deserialization with the RPC services (RemoteObject/RemotingService) but I'm not sure everyone realizes they can do this for messaging as well.

Issues in persisting dynamic entity and view objects using MDS

Hi All,
I'm trying to create dynamic entity and view objects per user session and to persist these objects throughout the session, I'm trying to use MDS configurations(either file or Database) in adf-config.xml.
I'm facing following two errors while trying to run the app module:
1. MDS error (MetadataNotFoundException): MDS-00013: no metadata found for metadata object "/model/DynamicEntityGenModuleOperations.xml"
2. oracle.mds.exception.ReadOnlyStoreException: MDS-01273: The operation on the resource /sessiondef/dynamic/DynamicDeptEntityDef.xml failed because source metadata store mapped to the namespace / DEFAULT is read only.
I've gone through the following links which talks about the cause of the issue, but still can't figure out the issue in the code or the config file. Please help if, someone has faced a similar issue.

Hi Frank,
I m trying to save entity and view object xml by calling writeXMLContents() and saveXMLContents() so that these objects can be retrieved using the xmls later on.
These methods internally use MDS configuration in adf-config.xml, which is creating the issue.
Please share your thoughts on resolving this or if, there is any other way of creating dynamic entity/view objects for db tables created at runtime.

BI-IP and Business Objects?

Please refer to the thread:
BI-IP and Business Objects?

Ian,
reading through the messages, there seem to be a few questions that are raised. After attending SAP Financials 2008, here is what I got from it:
1. IP vs BPC: IP is still in production and will be developed (no commitment on time though. I was told somewhere between 18-24 months before it goes to maintenance mode). There is some functionality difference from BPC and right now these are two separate products. There is a talk of a possible integration in the "distant" future
2. BPC is in process of being developed for BI, but currently it is only running on top of Microsoft SQL server. The BI version is slated to be released June 28th, but majority of the experts are fairly pessimistic about that date.
Now, the main question is what will happen to IP when BEx and BO tools converge into one - based on my understanding, we are going to see ADDITIONAL functionality. Since all the WAD and Excel activities are based on BEx API's, it is highly unlikely that they are going to be dismissed in the new product. The process in which we assign functions/commands to the planning model might change, but I think only for the best

Is in PI7.1 possible asynchronous communication between SOAP and ABAPProxy?

Hi,
when method execute_asynchronous has disapeared since XI/PI 7.1, is
there still way how to use ABAP proxy in asynchronous way?
We need to build asynchronous connection SOAP->PI->ABAP_Proxy.
In PI, both interfaces are defined as asynchronous (outbound for SOAP and
inbound for ABAP Proxy).
Despite of this fact, when message is sent, it is processed
synchronous way.
I have set breakpoint in my implementation of method for ABAP Proxy
message processing. When message is sent and breakpoint is reached,
whole connection stays open (between SOAP and PI and between PI and
ABAP Proxy) and waits for processing method (the breakpointed one) to
return. Only when processing method returns, is connection finelly
closed.
If i understand it correctly, this is synchronous behavior. In
asynchronous behavior, as i understand it, should be connection
between PI and ABAP Proxy of application server closed immediately
after message has been delivered. This mean before my processing
method is even called.
The same could be said about SOAP and PI communication. Connection
should be closed immediately after PI has received message. From
definition of asynchronous communication of PI is obvious, that PI
should receive message correctly and close connection to sender system
even when receiver is unreachable. It should deliver message later
when, receiver system is back on line. So why it keeps connection to
sender system open while it waits for receiver?
Why is this happening, when both interfaces are defined as
asynchronous? Could be the reason for this, if APPLICATION
ACKNOWLEDGEMENT is set on by default? If so, how can i change it
to SYSTEM ACKNOWLEDGEMENT, or disable it at all?
Or is this kind of asynchronous communication even possible since
XI/PI 7.1 ?
Processing of message we are sending can take some time, so we dont
want connection pending open while waiting for finish of
processing. Thats the reason why we have chose asynchronous model to
use.

Quote from How to Use the J2EE SOAP Adapter:
"If you select Best Effort, the Web service client will receive a response
message in the SOAP body. Otherwise, the Web service client will not receive a
response message if no error occurs."
"if no error occurs" - that is the problem. In either case he still
waits if some error occure or not. I dont want it. Once PI has
received message, I want the connection with sender to be closed. If
there will be error in communication between PI and reciever, I want
to see it only in PI log. That mean no notification to sender to be
send about that error.
Is that possible?

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object
reward if useful

Newbie question about entity and view objects

Hi everyone,
My first ADF application in JDeveloper is off to a difficult start. Having come from a forms background, I know that it is necessary avoid using post-query type lookups in order to have full filtering using F11/Ctrl+F11. This means creating an CRUDable view and getting as much of the lookup data as possible into the view without losing the ability to modify the data. In JDeveloper, I do not know how to build my data model to support that. My thought was to start with a robust updateable view as my main CRUD EO and then create a VO on top of that with additional EOs or VOs. But, I have found that I cannot add VOs to another VO. However, if I link the VOs then I have a master-detail which will not work for me.
For example, I have two joins to CSI_INST_EXTEND_ATTRIB_V shown in the queries below and need to have that show in the table displaying the CRUD VO’s data. It seemed that the best way to do this is to create a CSI_INST_EXTEND_ATTRIB_V entity object and view object. The view object would have two parameters, P_INSTANCE_ID and P_ATTRIBUTE name. Both the building and the unit are needed on the same record, and this is not a master-detail even though it might look that way. (A master-detail data control will not work for me because I need all this data to appear on the same line in the table.) So, I need help figuring out the best way to link these to the main (CRUD) view; I want as much of this data as possible to be filterable.
select
cieav.attribute_value
from
csi_inst_extend_attrib_v cieav
where cieav.instance_id = p_instance_id
and cieav.attribute_code = 'BUILDING NAME'
select
cieav.attribute_value
from
csi_inst_extend_attrib_v cieav
where cieav.instance_id = p_instance_id
and cieav.attribute_code = 'UNIT NAME'
Ultimately, I need to display a ton of data in each record displayed in the UI table, so a ton of joins will be needed. And, I need to be able to add records using the UI table also.
James

Hi Alejandro,
Sorry if I caused confusion with my first post. What I had in mind assumed that I could have a single CSI_INST_EXTEND_ATTRIB_V EO with a BuildingVO and UnitVO on top of it. So, I wrote the queries individually to show how I would invoke each view. When I realized that confused the issue, I rewrote the query to explain things better.
Now having seen your 2 queries. You need to create 2 EO. One for each table. Then create an association between the 2 aeO (this will be the join you are talking about). Then, you need to create a VO based on one of the EO and after you can modify and add the second EO (in here you select the join type).
After your done with this, youll have 1 VO that supports CRUD in both tables.
There were three tables in the query: CIEAV_BUILDING, CIEAV_UNIT, and T -- the main CRUD table. When you say that I should create two EOs, do you mean that they are to be for CIEAV_BUILDING and CIEAV_UNIT? Or, CIEAV and T? Assuming CIEAV and T, that sounds like it would allow me to show my building or unit on the record but not both.
By the way, everything is a reference except for the main CRUD table.
Look forward to hearing from you. Thanks for your help (and patience).

Beginners Guide sound installation -- OSS and ALSA objective features

Beginners Guide sound installation -- OSS and ALSA objective features needed
Hi,
In most wiki pages i just edit the things that i think need editing. Just look at the oss history
In all those cases i didn't really saw a need to ask for permission.. that would kinda destroy the wiki idea.
However i want to change the sound instructions in the beginners guide so i made a copy of the entire guide and the part that i changed there is: http://wiki.archlinux.org/index.php/Use … ling_Sound now i have a slight issue there. As you can see i'm in favor of OSS and because you can spot that it's not objective. Now i would ask 2 things.
1. Could you all post your features of OSS and ALSA
2. Once that's done can i have permission to place that section in the beginners guide? that will also include removing the sound installation from the beginners guide which i already did in my version
My personal reason to do this. i've read this and am since then pro OSS and against the ALSA/PulseAudio combo. i think that combo needs to get out of linux (most notably Fedora and Ubuntu) ASAP. and oss needs to go back into the linux kernel
Thank you for your time,
Mark

I'm an alsa/pulse user, so I'll give a bit of the 'other side'.
Alsa/pulse
Pros:-
network sound
advanced connection of sink/source (including merging sinks)
bluetooth support!
highly supported by existing apps, either through directly supporting Pulse or through its alsa plugin (you should not need to recompile properly-written apps which do not assume they should write audio data directly to hardware, I think I only needed to recompile mpd on my system)
Cons:-
Setup isn't the easiest. Can't comment vs OSS4 because I haven't tried it
OSS4
Pros:-
Everyone seems to say sound quality is better. I guess that's because they're comparing it with dmix alsa. Use pulse with alsa and you should not notice any difference in sound quality though.
Cons:-
Most apps nowadays default output to alsa. Meaning OSS plays them using an alsa plugin.
USB support is admittedly skimpy.
EDIT: Having read the sound article you referred to, my only comment is that the writer really has it in for Pulse... 3 seconds latency, where'd he get that from? I use pulse for audio recording (when I'm lazy to fire up JACK) and while there IS latency, its definitely in the ms range.
Thanx for the input

If you don't know, please don't put in wiki, this could cause unnecessary problems. As for the mms section:
If your stream sounds ugly in totem like it did with me then you could try to play it with another codec like ffmpeg (mplayer). That "fixed" the issue for me. This will not fix the issue that somehow pops up in gstreamer when playing MMS streams but it will give you the option to play it with good sound quality. Playing it in mplayer is simple:

Could you fix this? ffmpeg is not a codec . Also define ugly, and what is somehow?

As for the things you didn't know. As soon as i fully understand how i can get a microphone working in OSS i will add that to the wiki as well. Unless you already know it.. in that case, feel free to add it.
For the mic, I did get mine going. Can't remember just how I did mine (sorry, think I had to disable one of the inputs), but do remember to prevent it from passing through the speakers had to disable "Misc Microphone".

For libflashsupport on the same page you linked it clearly states:
# Flash V9 and V10 require libflashsupport to output sound via OSS. Typically a 32-bit version of the library is required.
# Flash V10 has a 64-bit version which requires a 64 bit libflashsupport.
Also i tested it with and without libflashsupport. On archlinux (x64 running here) there most certainly is a need for libflashsupport when you want to have sound in your flash. And yes i tested the archlinux OSS version and the mercurial version (running now) bith need it installed manually! On my pc sound in flash didn't work without it but did with it. So, no not removing from the wiki as it's needed. But i see you removed it for me! please do NOT do that if you didn't even verified it. I use flash 10 x64 and i need it!
As for the ffmpeg "codec" changed it to backend.
And i did get the microphone working near perfect: http://www.4front-tech.com/forum/viewtopic.php?p=13192
Now for some news you all might like.
On my school i need to do an investigation to whatever i want and i'm heavily thinking about investigating the pros/cons of alsa compared to oss (or oss compared to alsa). That investigation will take from monday next week till next mondey till friday 23 of oktober. In that investigation i'm going to do some in depth look of alsa and oss and that will include the usability as well.
Following up on that investigation i will spend another 8 weeks on my school making a volume control application that can be used with alsa and oss and easily expandable with other sound systems. The goal of this is to make one sound application that can manage (in the first place) alsa and oss. oss is going to be implemented and alsa is probably going to be dummy implemented because it's likely way to much for me to implement both.
Before you get to exited, both projects (investigating and making the application) are just made up today and i just don't know if both will get accepted by my school. I asked one teacher and he liked the idea a lot and could potentially have a value for the sound management under linux. Once i do get this started i will involve the community (YOU!) with this since this project can't be done without the community specially the investigation.
And once i start and have something to tell/ask i will blog about it on http://blog.mageprojects.com
edit::
And this idea already got dumped. read more a few posts down or click: http://bbs.archlinux.org/viewtopic.php? … 34#p612634

How to find out the PATTERN, GRADIENT and BRUSHED objects?

How to find out the PATTERN, GRADIENT and BRUSHED objects information in illustrator active document file. And also how to find the CMYK and RGB color information in illustrator file through javascript. Could you please provide any examples.

I tried using the below code. But for both "cmyk" and "grayscale" pattern it gives only CMYK. Kindly check and advise.
Code:
var docRef = activeDocument;
for(var i=docRef.inkList.length-1;i>=0;i--){
var inkRef=docRef.inkList[i];
var inkRefName=inkRef.name;
alert(inkRefName);
alert(inkRef.inkInfo.kind);
Thanks for looking into this.

How to find all those list of SAP standard and custom objects that are changed from a specific point of time

Hi all,
Please let me know the process to track or find all the SAP Standard and custom objects. that got changed from a specific point of time.
Is there any function module or any table where this change log is maintained.?
I just only need the details ,wheather that SAP standard or Custom object has got changed or not.
Thanks in advance

Hi RK v ,
I really don't know what your actual requirement is , but if you want to know the objects as per the modification , then transport request will be much help to you .
Have a look into table E070 and E071 .

DAO and Domain Object

hi,
Normally when i want to persist a domain object like Customer object to a database, my statements will be below,
// code from my facade
Customer cust = new Customer();
cust.setFirstName("myname");
cust.setLastName("mylastname");
// set another attributes
cust.create();
with this code i have a CustomerPersistence object to handler for create this customer record to a database. Now j2ee have a DAO pattern. So my question is,
1.where is a domain object within DAO pattern? --> because of we can reused domain object.
2.DTO is Domain Object, isn't it?
3.when i look at some articles about DAO, many of it will present in this way
facade -->create DTO --> call DAO (plus something about factory pattern)
i never see something like this
facade --> domain object --> dao
any suggestion?
anurakth
sorry for my english!!

Hi,
I am a bit confused about implementation of the domain model and I wondered if you could help. My main concern is that I am introducing too many layers and data holders into the mix. Here is what I am thinking.
DTO - used to carry data between the presentation and the services layer
Service Class - coordinates the calling of domain objects
Domain Object - models a domain entity, service layer logic specific to this object is to be implemented here.
Data Object - an exact representation of a database table. many to many relationship between domain object and data object.
Hibernate DAO Class - has no properties, just methods used for read and writing the object to the database. It is passed in the Data Object for persistence. Is it wrong that the DAO contains no properties?
Perhaps the domain object will contain each data object it is comprised of. I was originally going to keep calls to DAOs in the Services class (as recommended in http://jroller.com/page/egervari/20050109#how_to_change_services_logic ) but I am thinking that each domain object could expose a save method, and that method would co-ordinate persisting itself to the various tables it is derived from.
Does this sound resonable? I have trouble finding a pattern on the net that clealy defines the Domain Model. I was tempted to map Domain Objects directly to database tables, and simply persist the Domain Object, but this 1-1 relationship may not always hold true.
Thanks.

Download and Upload(!) ABAP-Source and DDIC-Objects?

Hi,
is there a standard transaction or third party tool
to download and upload(!!) ABAP-Source (function modules,
function groups, module pools, reports...) and DDIC-Objects
(tables, structures, data elements) to a local file system?
In terms of uploading these objects it would be desirable
that the transaction/tool creates packages/development classes/.. on its own.
I would need that to copy the same source and ddic-objcets to different customer systems without doing it "manually" everytime.
Does anyone know advice?
Thank you,
Bernhard

Best practice for saving and recalling objects from disk?

I've been using the OOP features of LabVIEW for various projects lately and one thing that I struggle with is a clean method to save and recall objects.
Most of my design schemes have consisted of a commanding objects which holds a collection of worker objects. Its a pretty simple model, but seems to work for some design problems. The commander and my interface talk to each other and the commander sends orders to his minions in order to get things done. For example, one parrent class might be called "Data Device Collection" and it has a property that is an array of "Data Device" objects.
The Data Device object is a parent class and its children consist of various data devices such as "DAQmx Device", "O-Scope Device", "RS-232 Device", etc.
When it comes to saving and loading data, the commanding class's "Save" or "Load" routine is called and at that time all of the minions' settings are saved or recalled from disk.
My save routine is more-or-less straight forward, although it still requires an overwriting "Save" and "Load" vi. Here is an example:
It isn't too bad in that it is pretty straight forward and simple and there also would be no changes to this if the data structure of the class changed at all. It also can save more generalized settings from it's parrent's class which is also a good feature. What I don't like is that it looks essentially the same for each child class, but I'm at a loss on an effective way to move the handling of the save routing into the parent class.
The load routine is more problematic for me. Here is an example:
Again, the desirability of moving this into the parent class would be awesome. But the biggest complaint here is that I can't maintain my dynamic dispatch input-output requirements because the object that I load is strictly typed. Instead I have to rely on reading the information from the loaded object and then writing that information to the object that exists on the dynamic dispatch wire. I also dislike that unlike my Save Routine, I will need to modify this VI if my data structure of my object changes.
Anyway, any input and insight would be great. I'm really tired of writing these same VIs over-and-over-and-over again, and am after a better way to take care of this in the parent class by keeping the code generalized but still maintain the ability to bring back the saved parameters of each of the children classes.
Thanks for your time.

I'm with Ben. Don't rely on the current ability to serialize an object. Create a save method and implement some form of data persistence there. If you modify your class you might be disappointed when you cannot load objects you previously saved. It mostly works but as soon as you reset the version information in the class, you can no longer load the old objects. This is fine if you know how to avoid resetting the history. One thing that will do this is if you move the class into or out of a library. It becomes a new class with version 1.0.0 and it no longer recognizes the old objects.
[Edit: I see that you are just writing to a binary file. I'm not sure you can load older objects anyway using that method but I have never tried it.]
This will not help you right now but there are plans for a nice robust API for saving objects.

Difference Between Business Object And Class Object

Hi all,
Can any one tel me the difference between business object and class Object....
Thanks...
..Ashish

Hello Ashish
A business object is a sematic term whereas a class (object) is a technical term.
Business objects are all important objects within R/3 e.g. sales order, customer, invoice, etc.
The business objects are defined in the BOR (transaction SWO1). The have so-called "methods" like
BusinessObject.Create
BusinessObject.GetDetail
BusinessObject.Change
which are implemented (usually) by BAPIs, e.g.:
Business Object = User
User.Create => BAPI_USER_CREATE1
User.GetDetail => BAPI_USER_GET_DETAIL
CONCLUSION: Business Object >< Class (Object)

Uwe
