Blazeds messaging services object cast

hi everyone i am new to flex and blazeds i am using messaging services for my app and sending objects through messages.
message.body = new object1()
message.body.object = someobject;
myproducer.send(message);
on recieving hand
i can reach message.body.object.name but when i assign this object to some object like
var newobject:type1 = message.body.object as type1;
and try to get name from newobject.name i got empty object error error type 1009
is there anybody help or any clue
thank you.

Ok, so well no one responded...In case anyone in the future
stumbles into this problem, I think I've found out the problem.
Since I was deleting this info, I was sending the delete
request to my java code (which read the array of ChartObjects and
deleted each one using the name of the chart to delete it from the
database) and then immediately afterwards, I was deleting the same
data structures in my flex code.
Apparently Flex doesn't copy the data and send it, but sends
the actual data or a reference to it. So even though my lines to
remove the data were after the database delete request, by the time
the database deletion got executed in the system, the data had been
erased by flex. It seems like Flex does not handle events in
sequential order as it is written in the code. I've run into this
in other places with messaging and flex. So I'll just have to
rewrite the logic to take into account this behavior.

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.

Can anyone please tell me where i m going wrong.Is that because i m using flex2gateway for java calls?.I used it since it was how it has been configured in the turnkey project for coldfusion.I have replicated the file as it was there and since it is using flex2gateway even for javaEndpoints i felt we could use the same.
regards
Sidd

Thanks for the reply. Yes, I did compile all the Java and it
works OK with a simple Java program. It just will not work in a
Flex application.
The java classes are:
RRA:
package blah.myPackage;
import java.util.List;
import java.util.Collection;
import flex.data.DataSyncException;
import flex.data.assemblers.AbstractAssembler;
class RRA extends AbstractAssembler
public Collection fill( List fillParameters )
RRS service = new RRS();
return service.getSome();
RRS:
package blah.myPackage;
import java.util.ArrayList;
import java.util.List;
import java.sql.*;
import flex.EORS.*;
class RRS
public List getSome()
ArrayList list = new ArrayList();
String str = "bob";
RR rr = new RR(str);
list.add(rr);
return list;
RR:
package blah.myPackage;
class RR
private String name;
public RR() { }
public RR(String name)
this.name = name;
public String getName()
return this.name;
public void setName(String name)
this.name = name;
I started with something that retrieved data from a database
but watered it down just to try and get some kind of communication
between Flex and Java.

Can objects returned from web services be cast to strongly typed objects?

Can objects returned from web services be cast to strongly
typed objects?
Last I tried this was with one of the beta of Flex2 and it
did not work. You had to use ObjectProxy or something like that...
Thanks

RE: Re[2]: Service Object events and LockMgr

I think there are a lot to implement a lock manager. If several objects
should be updated in one transaction, the lock manager should be able to
handle rollbacks. Other things like release lock when exception happens,
avoiding dead locks, etc. Most of the features are provided by DBMS, so
I think using a option 2 would be a better solution.

The second one - you just need some unique value that will identify
the object being locked. You should register with the Lock
Manager only
the objects that you want to lock.
For me, one of the goal of such pattern is to give you some freedom
from the specifics of the database lock mechanism.
Another benefit that I can see is that using such approach you can
always answer to the question: "Can I modify/delete this object?".

Re: Service Object events and LockMgr

On the option that you have considered, I have implemented the same model
in my previous project (using Java/RMI), but I felt that it is more than
what is normally needed for concurrency protection.
I can suggest another option that is worth considering which is in place in
our app for concurrency.
Almost every table in our db has created By, created On, modifed By,
modified On columns. The parent class of all business objects has
attributes that correspond to these four columns. In addition to these
four, there is a fifth attribute (introduced when concurrency was built)
called originalModifiedOn. Upon retrieval from the db, it is set to
modifiedOn value (from the db), during UPDATE, the value in this column is
added part of the WHERE clause. So when the second user tried to do save
the same object, the underlying db update will get a 'zero rows updated'
which is translated into an application error 'possible concurrency
error'. The user re-retreives the now 'stale' object before applying their
edits.
A lot of these things are and can be built into the framework imposing very
little work that each Object needs to do to have concurrency protection.
I am not sure if there is a mention in the Patterns paper of this model,
but it is very easy to implement and supports what is needed.

Hi folks,
We're currently looking at strategies for dealing with the simultaneous
updates to the database from multiple clients (concurrency
management). That is when two (or more) clients load the same object to
edit it, then make different changes and save them to the database.
We have a copy of a Forté document (from the "Patterns" course, I
think) which describes three methods of dealing with this:
1) Lock the database table row as soon as a client select it for editing
and hold the lock until it is saved.
2) Immediately before 'saving' check that the database hasn't changed
(either by reading what's there before updating, or by using a huge
'where' clause that contains all unchanged fields)
3) The Forté "LockMgr" pattern, which uses a service object with notifier
proxies to allow locking and updating notification between the clients.
Option 3 is obviously the most robust method, but it requires a fair
amount of coding and could also be a bottleneck for database reads and
writes.
But I have another option for which I was looking for opinions. What if
we had a "Change Event manager" which broadcast an event every time
a change is made to the database. Each business class would have its
own event. If the event had the object's primary key as a parameter, then
clients editing that particular object type could check to see if the object
currently on screen is the one that changed. That way you could disable
the 'save' until they had refreshed their on-screen data.
It's not particularily elegant, but it's reasonably simple to implement. It
also deals with changes sent across our WAN from other database
servers.
But this option is only worthwhile if you can replicate the "Change Event
manager" SO and still register for an event on the client. Can clients
register for SO events and receive an event generated by any of the SO's
replicates? Or when you register for an SO's event do you register for
only one instance of the SO?
Thanks in advance for any answers.

Hi,
Just wonder exactly how this Lock Manager can be implemented. Do you mean that you are
going to cache every object that is instantiated from the database? Or you just cache
the object id, primary key, etc?
Frankly speaking, I won't attempt to due with this kind of currency coding myself as
the database vendor has spent years in coding just to do this.
Regards.

I would recommend you to use the following approach (of course if you
do not have some special requirements :) ):
1. You should have a LockManager that will synchronize all clients in
their attempt to modify/delete objects in your application.
2. Each client, when attempts to modify/delete some object, it must
LOCK it using the services provided with the LockManager.
3. The requested operation can be performed only after successful
locking.
4. If a lock can not be obtained (for example if the object is already
locked by some other client) then the operation is aborted.
The details of this pattern depends on your needs. :)
Hope this helps.

Events in Service Objects

Hi,
Is it possible to have a service object checking permanently for events
posted by other service objects? I have not been able to start this type of
object.

I have something this (please, some patience :-) ):
//Example: handle event (the event is Beep)
interface AlarmListener{
void Beep(String hour); //declare a event handler
//The class that "raise" an event Beep
class Clock{
AlarmListener theAlarmListener; //Referecne to an listener object
//Register an listener object
public addAlarmListener(AlarmListener theAlarmListener){
this.theAlarmListener = theAlarmListener;
private ringAlarm(){
theAlarmListener.Beep("10:00 P.M."); //Raise Beep event
class Guy implements AlarmListener{
public Guy(){
Clock clock = new Clock();
clock.addAlarmListener(this);
//Handle Beep event
void Beep(String hour){
System.out.println("Ohhh, its time of wake up!!!");
//End
But, in this model my source object have only an listener object.
This can be improved by a array, like this:
class Clock{
AlarmListener[] theAlarmListener = new AlarmListener[10];
private int i = 0;
//Register an listener object
public addAlarmListener(AlarmListener theAlarmListener){
this.theAlarmListener[i++] = theAlarmListener;
//More code...
making to a side the limitation of size of an array (although this can be managed somehow if it is necessary), the problem begining to be more and more complex... i.e., it is necessary to create a method for unregister a listener...
And, what about with multi-threads programs??? The addAlarmListener method should be synchronized or something??
It should have an easier way!
PD: I think that I have used the Delegate pattern in conjunction with some other pattern.
PD: Forget my English. It is terrible

Service objects inside libraries (WAS: Interfaces in Forte -has anyon

The following message is actually not about interfaces, but libraries:
> From: Jeanne Hesler <[email protected]>
> To: [email protected] <[email protected]>
> Date: Thursday, July 30, 1998 11:12 AM
> Subject: RE: Interfaces in Forte - has anyone used them?
>>
> Just to clarify a few things:
>>
1) Just to be 100% correct -- it is actually Libraries that areloaded and
not Interfaces. The distinction is important because a librarycould
potentially implement many interfaces (or provide manyimplementations for a
single interface).
2) The code in a Library may reference a service object, but itmay not
define a service object. Of course any SO's referenced by thelibrary
must already be known to the loading partition. It is OK to havecode like
this in a library:
MySO.doSomething();
The documentation is a little vague on this point, but I haveconfirmed that
this is true through Tech Support and by experimentation.
Actually you CAN define and use service objects inside libraries
(compiled or interpreted) with two restrictions:
1) You can not define two service objects inside library in different
projects and call one of them from another. If you need that, both
service objects must be in the same project.
2) If service object is defined and used only by library (if it never
referenced directly by application code), than in order to be able to
partition application, you will need to create dummy method inside
application, which will reference this service object (you do not need
to execute this method - just have in the code).

The way stateful Web services are currently handled is through the use of cookies ... once your stub invokes a stateful Web service a cookie is created which routes subseqent requests back to the Web service.
In your scenario, the problem is given one client has creates Web service 1 and now Web service 2 would like to be able to use that state it really isn't possible unless you engineer a solution yourself ... you would need so somehow set the cookie on your Web service 2 client to that of the original client to Web service 1. State tends to be based around an individual client versus multiple clients for that state.
There are numerous ways around this but you would be engineering around the issue ... the easiest is to write the state out somewhere so that it can be shared.
This section of the doc gives a brief overview:
http://download-west.oracle.com/docs/cd/A97688_06/generic.903/b10004/javaservices.htm
Lastly be aware there is a bug with timeouts in stateful Web services in Oracle9iAS 9.0.3 that has been fixed in 9.0.4. I can't find the thread here that documents it but when I track it down I will post the link so you can see the workaround.

How to extract the Private Note data in Document Service Object?

HI EXPERTS,
In transaction ME53N, display document, click on the Service Object button and enter a Private Note.
How to extract this data and show it in a report?
Moderator message: please analyse yourself before asking, describe your own efforts and where you are stuck when posting again.
locked by: Thomas Zloch on Aug 19, 2010 1:33 PM

I did quite an amount of debug of transaction Code FB03.
SO_OBJECT_READ is the function module that is used to read this data.
The inputs are as below:
folder_id is generated from:
Within CL_GOS_SRV_PERSONAL_NOTE and METHOD check_status -->
        CALL METHOD cl_binary_relation=>read_links_of_binrel
          EXPORTING
            is_object              = is_lporb
            ip_relation            = 'PNOT'
            ip_role                = 'GOSAPPLOBJ'
          IMPORTING
            et_roles               = lt_roles
where
is_lporb-typeid = BKPF
is_lporb-catid = BO
is_lporb-instid = 'CompanyCodeDoc nofiscal year'
lt_roles-instid+12 is used for the SO_OBJECT_READ function module
Thanks,

RE: log trace on Service Object

I haven't tried myself; but got a copy from someone of part of technote
10398 which says (the minimum you need is:)
trc:in:1 Prints out information about interpreter state object.
10 - Print method entry/exit
trc:in:2 Trace the interpretation of method invocations and exception
handling
2 - Prints entry/exit and exceptions
trc:in:51:1 Traces method entry/exit by task
trc:in:54:1 Traces method entry/exit by application

Hi Eric,
You can find on http://perso.club-internet.fr/dnguyen/ a little tool called CodeAdd which adds Entry and Return trace. I fact, you
can use it to add any kind of code at the beginning and the end of your methods.
It also allows you to add a pre-formated comments header in you code.
In a further version, It may be possible to replace a code sequence from your methods. For instance, you may add a trace class and
change a task.Part.LogMgr.Putline by a call to your own class, or need to suppress some lines.
Just be carefull to use the tool on a local backupo of your repository : CodeAdd updates your methods directly in the repository.
Hope this helps,

RE: (forte-users) User-visible service object

This solution will cause network traffic for all method calls on the
environment visible SO. This overhead is not incurred when calling methods
on a user visible SO in the same partition. Depending on the frequency of
calls and the volume of data being passed in and out, this could be
significant overhead.
We have successfully implemented the following.
Create a second User Visible SO based on the same class. Then you will be
able to partition the one SO into the client partition and the second into
the server partition.
For example, assume the underlying class is named MessageService then define
your SO's as
ClientMessageService -> MessageService
ServerMessageService -> MessageService

Hi folks!
We've got a user-visible service object that handles
initialisation of and
access to the message catalog.
This works well on the client, but we would like to use the
same
mechanism (and even the same service object) on the server
so that
service objects on the server have access to their message
catalog on
the
server.
I was hoping that if we referenced this user-visible service
object in
both the client and the server code, that it would partition
a copy in
each of the client and server partitions. However, we
cannot get this
user-visible service object duplicated on the server. If we
drag and drop
it onto the server partition in the partition workshop, it
disappears from
the client partition!
Anybody got any idea how we could do this?

I would try going to the "lowest common denominator" between WindowsNT and
Windows95 - DOS. Both windowing OS's sort of have their roots in DOS, or at
least both are capable of opening a DOS session.
Therefore, from a DOS prompt type "set" to view the environment variables for
both OS types. Look for a common variable between the two that stores the
userID. If you can find one of these your application will be that much more
portable between these two Windows mutations.
I used "set" on my NT and found my userID assigned to a few variables. I haven't
done this on a Windows95 machine in quite some time, but if the machine is on
the network it should have at least one environment variable with the userID.
I'm just guessing that DOS has a variable to store the userID that will be
common to both machines.
Good luck....

Yes. Messaging service should started automatically.
I think you need add your object name under Messaging service-->Right click-->Choose properties---Log on tab.. then this service starts automatically.
