Data service returning an empty object

Hi
I am trying to call a data service from the flex to load my
data grid. In the debug, i saw that the arrraycollection in the
fill method is being returned empty. here are the details....
My .java file has the same names with the set and get
functions which are set by my java assembler class.
I am calling other fill methods and they seems to be working
fine except this one....

The problem was that the name of the destination
"codecoverage" was same as that of one of the packages where my
.java file was there. Changed this name and things started to
work..:-)

Using PHP Data Services to create an object and accessing that objects data in an unbound way in AS

Hello,
I've been able to use the php data services and bind the results of a function to a component. However I am having a hard time figuring out the syntax to use the data services to create an object out of the results, and then use that object as an array of filenames to provide the current index of the filename to a new sound object.
My problem is obviously in not being able to figure out the specific syntax, I have declared the service and and object of the services returned type and in the creationComplete() function I have assigned object.token = service.getData();
I've tried various ways of then pulling that data out of the object, with no success.
Can someone point me in the right direction?
This code probably looks horrible because it doesn't work yet.

Hello Joel;
In retrieving your data - what is your php returning to FB, an object, object array, an array? Either way, I have a brief example below that an object(s) is being returned. Pull the data from the lastResult in a ResultEvent. The object instantiated in the resultEvent will contain your data and you can do what you want from there.
Also, I always use Network Monitor to see what data (if any) is being returned from the server, you can also see how it is being sent back.

    var info:Object = mp3Array.lastResult;

What happens when a OUT parameter of a web-service returns an empty string

Hi,
Any idea on how to deal with the situation when a web-service returns an empty string
I get the following System Exception:-
Caused by: java.lang.AssertionError: Attempt to set empty javaType to ticketResponse(out,0) :: fuego.type.FuegoClass$LazyRef@6770f2. It must be null or a valid java type.
It therefore either expects a null value or a valid java type...
Since it goes into a system exception, the activity is not completed and nothing is inserted into the web-service..
How do we resolve this error inside of BPM?

Thanks Ben for your replies.
Before I attempt changing a VI that was written by a client and make a total mess of it, there's something I'd like to point out.
I tried the re-entrant VI approach and that didn't go any further than the VIT approach, and probably for the same reason(s).
The interesting part is that (with the VIT approach) the same VIT is called by another process and it works fine. It is just for the process that has it appear within 2 sub-panels. So the issue is related to having either having two instances spawn at once of the same VIT or it is related to the sub-panels. I think it is the two instances (or copies of the VIT) that causes LV to caugh...
So you are trying to tell me that the above description is accurate and it is because of the private methods...??...
How would I "wrap" those private methods into public ones? The seems to be a piece of this puzzle that I am not yet grasping..
Thanks for your patience and help.

Zend AMF Data Service Return Problem

Hi Folks,
I am working with FB4 and Zend AMF/PHP and MySQL. I began integrating the PHP stuff using the great article by Mihai Corlan called 'Working in Flash Builder 4 with Flex and PHP. I followed all the steps exactly, aside from creating my own app-specific PHP classes and functions, etc... I 'hooked up' the Zend stuff just like the article, created a text datagrid, just like the article, and viola!, it worked. I then tweaked it a bit and interwove it into my 'real' component. So far, so good.
Then I created a second PHP class with a different 'get data' type of function. It queries a different table in MySQL, but is essentially the 'same' as the query/function in the initial PHP class.
In FB, in the Data Services window, I choose the 'Connect to Data/Services' function, just like the first time. I then find/select my PHP class file and FB 'interrogates it' enough to show me the function that exists in the class. I 'finish' the operation and it adds a new 'service' to the list of services in that window. Again, so far, so good.
The problem comes when I try to 'test' the service or 'configure return types' (which basically requires a 'test' operation anyway). I can enter the 'input' params just fine, but when I try to execute the call, I get the following error:
InvocationTargetException:There was an error while invoking the operation. Check your operation inputs or server code and try invoking the operation again.
Reason: An error occured while reading response sent by server. Try encoding the response suitably before sending it. e.g. If a database column contains UTF-8 characters then use utf8_encode() to encode its value before returning it from the operation.
I don't know where to go after this. Again - the 2nd PHP class is essentially identical to the 1st. The function in it is essentially identical, differing only by the input params, the name of the function and the actual SQL it sends to MySQL. There is no special text, no special characters, no image stuff, nothing. I do not 'encode' the results of the function in the first class - in fact the code in the second class is practically identical to the first. I do not know what the error is talking about. My guess is that it's more of a generic message.
I can debug the PHP code just fine from within a seperate instance of Eclipse. The function runs/returns just fine - an array of PHP-defined objects (simple strings).
Any insights or advice would be welcomed.   Thank you,
-David Baron

Thank Jorge, but that was not the issue, though, it may be related.
I checked the mySQL my.ini file, and there was already an entry for:
[mysql]
default-character-set=utf8
I added the 'default-collation=utf8_unicode_ci', like you suggested, but that didn't do anything.
I checked the Apache httpd.conf file, and added the following line 'under' the "DefaultType text/plain" line:
AddDefaultCharset UTF-8    but that did not do anything.
I checked my mySQL database, all the tables involved. They were already at UTF-8 (default). However, some of the 'varchar' columns were defined as 'latin 1-default collation'.   I changed them all to utf-8 (default table collation), but that did not help either.
Finally, I found the problem, though I don't really know if it is "my" problem, or ZendAMF's problem, or Adobe's problem.
It turned out that 'some' of my data had a 'bad' character in it. Specifically, I had 'copied and pasted' some data from MS Word into mySQL Workbench. Some of the data included the 'elipsis' character - you know, when you type "..." (dot dot dot) in MS Word, it replaces the three periods with a single elipsis character. Although PHP could easily query and assemble this data into a nice object array, I noticed that that character showed up (in PHP's debugger) as a 'box' character, meaning "bad character". Thus, I guess, Zend AMF and/or FlashBuilder could not 'bring over' and/or deal with this type of character. As soon as I replace the few instances of that character with three periods, everything began to work perfectly.
So... what to do about this? I thought I was through with silly encoding/decoding of data when I left JavaScript and HTML behind in moving to FlashBuilder technology. Am I really going to have to worry about this kind of thing? Or might this be a bug/deficiency somewhere in the stack?
Thanks for your help,

How can I get rid of a type generated by the Data/Services return type wizard?

Hi All,
I have a JSON service that returns an object called "error". The Data/Services "Configure Return Type" wizard automatically turned this into a class "Error".
However, this caused over a hundred errors to show up inside the generated classes, "Call to a possibly undefined method Error." That's because of lines like this:
throw new Error(propertyName + " is not a data property of entity Agreements");
It's trying to throw a regular "Error" object, but now that there's an "Error" class in the same package, that is taking precedence--and that Error object doesn't have a constructor with a single parameter. At least, that's what I think is going on.
I tried to fix it by deleting _ErrorEntityMetadata.as, _Super_Error.as, and Error.as from the valueObjects package. I then opened the FML file and deleted the definition for the entity "Error" and every reference to the Error entity (class) in my FML file.
I then changed my JSON service so that it returns an object called "serviceError" instead of just "error".
But, whenever I re-run the "Configure Return Type" wizard, it regenerates the Error class, even though I've deleted it from everywhere I can find it. That breaks my project completely! How can I end this and get Flash Builder to *stop* generating this type!
In the "Configure Return Type" wizard I very carefully inspected the type of every bit of data coming back to make sure none of them show up as type "Error." And they don't (as expected, since I changed the object's name to serviceError--now the type of that object is ServiceError.
-Josh

I think you are facing this known issue https://bugs.adobe.com/jira/browse/FB-29770
Please vote it.
Thanks for the link--I just voted for it.
To avoid this, in the last page of "Configure Return Type", edit return type name to something else (You can also edit subnodes's name too in the wizard).
Actually, that's exactly what I saw doing; I apologize if that wasn't clear in my post.
I closed and restarted Flash Builder, and once I did that Flash Builder stopped generating the Error class. My guess is that the FML file, even though I had updated it (by deleting all references to the Error class), was cached in some fashion by Flash Builder, and restarting Flash Builder forced it to reread the FML file?
Additional point of clarification: my understanding is that the FML file stores all the metadata about the services that Flash Builder has been able to figure out so far, and when you run the Configure Return Type wizard, it will regenerate *every* type in the FML file, even if that type is not mentioned anywhere in the particular return value that you are working with.
Edited to provide additional thoughts on FML file.

Can a remote service return a remote object?

Hi all,
please consider a business logic for a typical forum service :
public interface ForumManager extends Remote
Forum createNewForum(String Name);
Forum getForum(String Name);
public interface Forum extends Remote
void postNewArticle(String Title, String Content);
Article [] getArticles();
public class Article implements Serializable
There are two interfaces of remote objects: ForumManager and Forum, both of two interfaces are extended from interface Remote. I created two classes implementing these interfaces respectively, and created two stub classes from the implementation with rmic.
As the logic, a ForumManager creates and manages forums on the server. A client can retrieve a remote stub of a forum instance from the manager stub, and post articles to the forum stub. The forum stub then sends the new articles to the real ForumImpl on the server, and the real implementation of Forum on the server then save the articles into disks or DBs. So, you can see, the most important thing is that clients have to be able to get the stub of a forum.
Codes in createForum() of the implementation class of ForumManager is like this:
ForumImpl TheNewForum = new ForumImpl(this.getRef());
// ^ Because ForumImpl is a remote object, without a ref, it can not be marshaled.
ForumTable.put(Name, TheNewForum);
return TheNewForum;
The problem is, the Forum instance my client retrieved from FourmManagerImpl_Stub (gotten from Naming.lookup()) is a ForumImpl, but not a Forum_Stub. So that articles posted to the forum will not be sent to the server, and different clients can not share articles with each other. I found a bunch of documents about RMI, but they did not illustrated how to retrieve a stub of a remote object from another remote object (like a manager). If you know how to cope this problem, please tell me.
Edited by: DBPZ on Apr 2, 2008 3:33 AM

why does this base class exist?It's really only there to support stubs. The only thing it gives you over Object is the remote equality semantics, and only stubs need that. (It also provides the RemoteReference but only RMI needs that, internally, you don't.)
When should we use RemoteObject instead of UnicastRemoteObject?Never, but if you do, or you use Object (or indeed anything other than UnicastRemoteObject and Activatable), you have to export it yourself as indicated above.

Flash Builder 4.5 Data Services Wizard, setting up REST service call returns Internal Error Occurred

Dear all -
I am writing with the confidence that someone will be able to assist me.
I am using the Flash Builder Data Services Wizard to access a Server that utilizes REST type calls and returns JSON objects. The server is a JETTY server and it apparantly already works and is returning JSON objects (see below for example). It is both HTTP and HTTPS enabled, and right now it has a cross-domain policy file that is wide open (insecure but its not a production server, it's internal).
The crossdomain file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
   <allow-http-request-headers-from domain="*" headers="*" secure="false"   />
   <allow-access-from domain="*" to-ports="*" secure="false"/>
   <site-control permitted-cross-domain-policies="master-only" />
</cross-domain-policy>
The crossdomain file is in the jetty server's root directory and is browseable via HTTP and HTTPS (i.e. browsing to it returns the xml)
Now before all of you say that using wizards sucks (generally) I thought I would utilize the FB Data Services Wizard as at least it would provide a template for which I could build additional code against, or replace and improve the code it produces.
With that in mind, I browse to the URL of the Jetty Server with any web browser (for example, Google Chrome, Firefox or IE) with a URL like this (the URL is a little confidential at the moment, but the structure is the same)
https://localhost:somePort/someKey/someUser/somePassword/someTask
*somePort is the SSL port like 8443
*someKey is a key to access the URL's set of services
returns a JSON object as a string in the web browser and it appears like the following:
{"result":success,"value":"whatEverTheValueShould"}
Looks like the JSON string/object is valid.
I went through the Flash Builder Data Services Wizard to set up HTTP access to this server. The information that I filled in is described below:
Do you want to use a Base URL as a prefix for all operation URLs?
YES
Base URL:
https://localhost:8443/someKey/
Name                    : someTask
Method                    : POST
Content-Type: application/x-www-form-urlencoded
URL                              : {someUser}/{somePassword}/someTask
Service Name: SampleRestapi
Services Package: services.SampleRestapi
datatype objects: valueObjects:
Completing the wizard, I run the Test Operation command. Remember, no authentication is needed to get a JSON string.
It returns:
InvocationTargetException: Unable to connect to the URL specified
I am thinking - okay, but the URL IS browseable (as I originally was able to browse to it, as noted above).
I continue to test the service by creating a Flex application that accepts a username and password in a form. when the form is submitted, the call to the service is invoked and an event handler returns the result. The code is below (with some minor changes to mask the actual source).

It's a simple application to be sure. When I run it , I get the following returned in the text area field txtAreaResults:
An Internal Error Occured.
Which is equivalent to the following JSON string being returned:
{"success":false,"value":"An Internal Error Occured"}
It appears that the call is being made, and that a JSON object is being returned... however it does not return the expected results?
Again the URL constructed is the same:
https://www.somedomain.com:somePort/someKey/someUser/somePassword/someTask
So I am wondering what the issue could be:
1) is it the fact that I am browsing the test application from an insecure (http://) web page containing the Flex application and it is accessing a service through https:// ?
2) is the JSON string structurally correct? (it appears so).
3) There is a certificate enabled for HTTPs. it does not match the test site I am using ( the cert is for www.somedomain.com but I am using localhost for testing). Would that be an issue? Google Chrome and IE just asks me to proceed anyway, which I say "yes".
Any help or assistance on this would be appreciated.
thanks
Edward

Hello everyone -
Since I last posted an interesting update happened. I tested my Flex application again, it is calling a Jetty Server that returns a JSON object, in different BROWSERS. I disabled HTTPS for now, and the crossdomain.xml policy file is wide open for testing (ie. allowing every request to return data). So the app accessing the data using HTTP only. Browsers - IE, Opera, Firefox and Chrome. Each browser contained the SAME application, revision of the Flash Player (10.3.183.10 debugger for firefox, chrome, opera, safari PC; 11.0.1.129 consumer version in IE9,) take a look at the screen shot (safari not shown although the result was the same as IE and chrome)
Note that Opera and Firefox returned successful values (i.e. successful JSON objects) using the same code generated from the Data Services Wizard. Chrome, IE and, Safari failed with an Internal error. So I am left wondering - WHY? Is it something with the Flash Player? the Browsers? the Flex SDK? Any thoughts are appreciated. Again, the code is found in the original thread above.

Using SMS to Package Data Services Silent Install not creating shortcuts

Hello,
My client has successfully created a package to install DS 3.1 using SMS (Microsoft Packaging) but after the Instalation runs, there is no startup folder created, or shortcuts to kick off any o fthe products. Has anyone run into this issue? How did you resolve it? Thanks! Ken

Hi Ken,
After installing DS XI 3.1 you will have data services available under following path i.e C:\Program Files\Business Objects XI 3.1 \Business Objects Data Services ....'. Also check control panel and see whether you can see the following services
1. Business Objects Data Services
2. Business Objects Address Server.
Sorry i don't have knowledge on SMS.
Thanks & Regards

          return array($person1, $person2);
create a new "flex" project in FB Beta1 with a php server. Setup the application and php script as normal, then configure the return type for the getPeopleInMyWorld function. I created a new return type called "Person" and was quite please to see that FB automagically created a "Cars" class with the all the right properties.
Unfortunately, if you run the code (try debug mode and put a breakpoint on the result handler) you'll notice that "john doe" has lost his cars and that you also get the silent (check console) error:
TypeError: Error #1034: Type Coercion failed: cannot convert []@1226bc49 to mx.collections.ArrayCollection.
any ideas??
i can get this to work by using json, but it's extra work, the com.adobe.serializers.json.JSONDecoder has little documentation, and the method outlined above is just begging to work.
so, how are the rest of you getting complex data back from your servers? json?? amfphp?? xml (but surely not)??
also, since i'm here discussing data services, if any adobe ppl are about, please throw one extra voice behind the following feature requests:
1) support for optional service call arguments (http://bugs.adobe.com/jira/browse/FB-19659)
2) a button for automatically 'generating service calls' from within the data services panel.

Thank you Gaurav for pointing me in the right direction. There was some debate in the blogs as to which data transferring method (amfphp, json, or xml) was best. See
http://blogs.adobe.com/mikepotter/2006/07/php_and_flex_js.html
and
http://www.5etdemi.com/blog/archives/2006/12/clearing-the-fud-on-amfphps-speed-versus-json -and-xml/
I used json yesterday
php: json_encode(array($p1, $p2));   // observation: you only have to encode once as opposed
                                      // to using amf on each array...
FB:   private var jsonD:JSONDecoder = new JSONDecoder();
      var jsonString:String = {{{return result from service call}}}
      myPeople:ArrayCollection = jsonD.decode(jsonString, services.personservice.Person);
Note that in FB you can use the services.personservice.Person class as an optional argument in the jsonD.decode function. This class can be automatically generated using FB's built-in data service's panel when you try to configure the return type (as I described above). The json data should unserialize correctly with Cars objects automagically created and everything (a huge time saver!!).
It worked for me, though I'm not sure how deep the unserialization process is capable of going (objects within objects w/in objects, for example). Also I had some trouble with adobe's jsonDecoder; it had trouble eating (uhm parsing) hollow objects (i.e. objects with null properties), whereas the php_encode / php_decode handled these objects w/o fail.
Anyway, will be reading up on amf. Tanx again Gaurav,

Web service task: Error when returning an empty array

Hi,
I've encountered an annoying error when using a Web Service Task from an SSIS package in SQL Server Data Tools.
[Web Service Task] Error: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: Index was outside the bounds of the array..
at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection)
at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser)
at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()".
It seems that the Web Service Task generates this error when returning an empty response from the WSDL. I've seen several topics about this here on MSDN but they are all from 2008-2009 and seem to suggest that
this is a bug. The workaround suggested is using a script task but I would really love to avoid that since my programming skills are lacking.
I'm using Visual studio 2010 with SP1.

Hello,
From my own experience: in all the cases where I had to use SSIS 2008 to retrieve data or send data to Webservices, I had to revert to using Script Tasks or Script components. Whenever I tried with a Web service task, because the job looked simple, I had
to abandon it in favour of Scripts. Keep in mind that I try to make use of the SSIS components as often as possible, before reverting to Scripting. But handling web services is the one exception, where I always use scripts. In SSIS 2012 I did not find
any significant improvement of the Web service task and hence no compelling reason to use it.

Data Service Wizard - How can I reconfigure return type field as XML (E4X) value

The HTTP Data Service wizard - "Reconfigure Return Type" - does not allow XML (E4X) to be selected as a data type for a field. For example , If my example XML payload looks like this (see below), I would like to set the datatype for "settings" field to be XML (E4X) and have the service decode the "string" value into an XML (E4X) value.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ListOfUsers version="1.0.0">
    <User>
        <id>3</id>
        <subType>INTERNAL</subType>
        <authName>internal</authName>
        <name>Internal User</name>
        <settings><?xml version="1.0" encoding="utf-8" ?><Settings><Profile><Region>emea</Region><Language>en.g b</Language></Profile></Settings></settings>
    </User>
</ListOfUsers>

I find a (reasonably) elegant workaround which is to add a transient property in the "public" sub class of the value type - see below - I havent tested it much so not sure if it will work adequateky in all circumstances
package services.listeningpost
public class User_type extends _Super_User_type
public function get xmlSettings():XML
return new XML(settings);
public function set xmlSettings(object:XML):void
settings = object.toXMLString();

Data service complex object deserialization

I am building a simple data services application that has a
many-to-one association between two classes:
public class Product {
public var title : String;
public class LineItem {
public var product : Product
public get function title() : String { return
this.product.title; }
I am trying to populate a DataGrid with a list of LineItems,
using the product's title in one of the fields. It seems, however,
that the LineItem product property is populated with an Object, not
a Product when returning from the DataService call. From I have
read (see #9), this
seems to be expected based on how the Flash player deserializes
data.
My question though is if there is an easy work around for
this problem? Thus far, all I have found that works is to access a
LineItem from the DataService result after it completes, but that
seems very hack-ish to me.
Thanks,
Josh

The InputRender is the recommended tag for complex types. The only problem is that it doesn't (currently) support object types. It supports interMedia types. You need to use the ShowValue tag and the SetAttribute tag in order to update your complex type. In our next release we will add object support to the InputRender tag.

FB4, Data Services&PHP returned data is lost

Hi,
I set up an RPC call using the data services, all works fine so far. Fb built a dataType for me holding all the returned variables. Now I let Fb generate the communication forms for me. This results in a form where I put in the parameters and hit the button that triggers the call. And a second form that is supposed to show the results. Now whereas the call of the rpc works fine, the results are never shown. When I dump in the php what is supposed to be returned all looks fine.
As far as I understand Fb sets up an RPCManager that is supposed to handle the result. But I do not understand how to trace the callback. (I used to use the HTTPService where I set up a callback event manually, this was easy to trace but I am kind of stuck with the RPCManager).
Is there a possibility to track the callback function that is supposed to handle the return values of the rpc call? PHP returns an associative array, when I configure the Data service in Fb all fields are correctly identified. What could be a reason for the result form not to show anything? Using RPCs that return a single string only works fine!
THX in advance.

Just to add some infos:
Configuring the service works fine: Fb shows that an object consisting of five strings is returned and this is exactly what happens.
But when using this service the lastResult value is always NULL. That seems strange to me.
old amfphp used to have a service browser is there anything comparable for the ZendFramework? I´d love to find out where the data is lost. Resp. what the difference is between the calls when configuring and the calls coming from the application...

Business Objects and Data Services on VMWare

My company has a requirement to deploy Business Objects 4.0 as well as Data Services.
We are going to be deploying them on Windows Server 2008 R2, hosted on a VMWare cluster. I have reviewed the PAM, but my question is:
Will these run using SQL Server 2008 R2 as a database? I see "SQL Server 2008" and I am just curious whether R2 is also supported?
Thanks.

Hi,
SQL Server 2008 R2 is listed in the PAM for DS as Repo DB. For BI4 it is also working and supported. I installed it already on it.

Extract account Based COPA from R/3 using Business Object data services

Hello,
We have a requirement to extract Account Based COPA from SAP R/3 to Teradata using Business Objects data services.
I have read couple of white papers which give information on Rapid Marts( which are built in packages) already available for some applications like inventory, GL, AP, AR etc. But I could not find anything for COPA.
Would anyone give me any information on how to use BO data services for COPA?
Also if there is no rapid mart available for COPA, does anyone know how to create custom data marts in BO Data services?
Is there any document available on this?
Please respond as soon as possible.
Thanks.

Hi,
this forum is for the SAP Integration Kit. Would suggest you post your question into the EIM area for Data Services.
