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 Service: Response has null value and no exception is thrown

Hi
I have generated a Web Service Proxy in JDeveloper 11gR1 against a web service.
My problem is that if I try to invoke the web service programmatically the only property on the response object has the null value. I can inspect the response in the Http Analyzer and it seems to understand and display content of the response properly.
I have debugged the service proxy and discovered that the set-method on the property is never called. No exceptions are thrown, so it is very hard to see where to start solving this issue!
Any ideas?

When a webservice provides a response that is not valid according to its wsdl, a webservice proxy in 10g will give useful error messages such as "Missing element 'xxx'."
In 11g the web service proxy simply sets non-valid values to null, quietly accepting the invalid response. Is this the intended behavior?
Is it possible to enter a debug mode, where the webservice response is validated against the wsdl as in 10g?
I appreciate any help on this question.
Thanks!

Set listbox items from web service response

Hi All
I am trying to set list box items from a web service response. Couple of issues over here:
1. The user should be able to select multiple items from the list. Hence if I set "Allow multiple values" and set Commit on "exit", then after the web service returns the output, no data is displayed in the listbox. I need to click inside the list box to see the data returned by the web service. How to overcome this..?? ( However this problem (clicking inside the listbox to see the items) does not exist if "Allow multiple values" is unchecked and Commit is set on "Select". )
2. After the list box is filled up, certain default values should be selected. This selection is based on one of the response field (which is actually a table with multiple values... ). Hence, how to capture this response field and set the default values in the above list..??
3. The same case for a dropdown. The values are visible in dropdown. However, a default value should be selected and displayed after returning a response from web service. Again, this default value is dependant on another field in the response as in point no.2
I am trying to use postExecute event as described in [this|http://forms.stefcameron.com/2009/03/23/pre-process-web-service-responses/] link...however not able to achieve the functionality. Please provide suggestions / inputs.
Thanks
Deepak

Hello,
first: I don´t know anything about the right solution. I am unaware of the existence of the solution, because there were quite many of question about this multiple selection problem and I don´t remember a single "answer".
I can recommend you to simplify everything and create the functionality yourself. I have done that before to avoid these "Adobe-standard" problems. If you have a problem with autofill of the object, ask your WS to send you a single string and pass it yourself using scripting (JS).
And if you have problems with multiple selection, create your own field/ object. Get the string of values, parse it, create multiple lines of the dynamic table with some suitable tool to check/ select the rows you need (use checkbox for example, and your text as a table row). This way you can selected anything you want with no problems at all. It wil only cost you some extra work.

CANNOT_READ_PAYLOAD error in Web Service Response

Hi experts,
We are deploying a webservice on SAP PI, when we call the SAP PI webservice directly, everything works normal, and we get a response.
When we call the SAP PI web service through a different J2EE web service, the fields in response are null(though the SOAP message is received), because PI is not able to get the PAYLOAD in the SOAP request, the following error is obtained in the response.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- 
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
<SAP:Category>XIServer</SAP:Category>
<SAP:Code area="MAPPING">CANNOT_READ_PAYLOAD</SAP:Code>
<SAP:P1 />
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />
<SAP:AdditionalText />
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>Unable to read payload from the message object</SAP:Stack>
<SAP:Retry>N</SAP:Retry>
</SAP:Error>
Every other configuration and the web service settings used are the same, Only the direct call to a WEB SERVICE DEPLOYED IN SAP PI engine is redirected through a WEB SERVICE deployed in J2EE engine to the SAP PI engine, is causing problems.
Please Help..Urgently.
Thanks..

Hi,
Are both requests (plain PI and WS encapsulated) strictily identical ? If PI can not parse body when intermediate WS is invoked, it might be due to a (slight) change in the WS request (ie namespace, declaration etc) ...

How to use a Web Service Response

In the snps_users documentation it seems to be really easy but in fact...
After invoking my web service I retrieve a XML file which is my response then we would like to use it.
As written in the documentation I Export Response in XSD file, I create my XML Model but How to reverse the XSD ???
There's 4 references to XSD into all the snps_users documentation but no one talking about.
Moreover it's written See Creating and Reverse-Engineering a
Model for an XML file for more information and that's what I'm doing but no way...
So without the XSD I m trying to use the Response file like an XML file but I always have an error which looks like :
java.sql.SQLException: No root found in the DTD file
The Web Service Response XML File use NameSpace could the problem come from here ???
If someone ever use it ...
Thanks in advance.
BM

When I specify the XSD It raises another error,
my URL is :
jdbc:snps:xml?f=C:/Temp/File.xml&d=C:/Temp/File.xsd&s=REPON&nspg=xml
Error message:
java.sql.SQLException: A SAXException was caught while reading the model saying [Element value has no type]
The XSD and the XML are generated by ODI after invoking a Web Service...
Any idea ???

MTOM Encoded Web Service Response

Hi,
I am trying to call from APEX some web services that are MTOM encoded and the calls are failing.
Does APEX support MTOM encoding? I am using the apex_web_service.make_request function.
Below is a comparison of 2 service raw responses from soapUI, one that works with APEX and one that doesn’t.
Service 1 Raw Response:
HTTP/1.1 500 Internal Server Error

--uuid:2505d950-8e95-4cd7-a350-a73962f5b748—
Service 1 works with APEX, it has a standard “application/soap+xml” content type and XML follows immediately after the header, which APEX expects and is able to parse.
Service 2 does not work with APEX, it has the specific MTOM “multipart/related;type="application/xop+xml"” content type and after the header the uuid reference for the multipart response.
Any idea on how to handle these types of web service calls from APEX?
Thanks!

Hi
Have you found the workaround?

Web service response processing inside a BPM

Hi Experts,
Please can you let me know if it is possible to achieve the following inside a BPM:
u2022     Once you getting the web service SOAP response, determine if itu2019s a SOAP fault or a normal web service response.
u2022     If itu2019s a SOAP fault, create a retry loop with a wait step inside the BPM to try and retry the process (perhaps 5 times in 1 minute intervals).
u2022     After the retry intervals, if the message is still in a failed step, force the BPM to go into an error state
u2022     If the Web Service returns a normal response, log the response inside a database table and end the BPM
If it is possible, please can you provide an example?
Thank you,
Brendon

Web service response contains SOAP Headers with "mustUnderstand" true

On executing the service now through web dynpro we are getting the below error
"Web service response contains SOAP Headers with "mustUnderstand" true which are not handled by the client runtime"
Any thoughts on how to handle this mustUnderstand attribute with some code snippet? Appreciate all help.

Complex types returned from web services

I'm having problems getting values from a complex type from a

Problem in passing/returning objects over dynamic web service call

Hi Friends,
I am beginner in java web service.
Here is the problem I am facing when I pass/return user defined objects to remote web service method using dynamic we service call.
The client can call the remote web service method in 2 ways.
1. By generating client stubs using WSDL file
- In this case, I am able to pass/return the user defined objects to remote method without any issue only when the server side web services are deployed in any server(jboss)
- But in java 1.6 & above, the web services can be deployed without server using endpoint. In this case, I am not able to pass/return objects over web service calls.
2. Without generating client stubs (dynamic web service call)
- This will establish a connection at run time using the given WSDL file (I have attached the document). I have to form an XML(This will contain API name, arguments) string as input at run time
- In this case, it allows only string as argument while passing & returning.
Please let me know if you can help me on this.
Regards,
pani

Proxy object to consume web service

Hi,
I want to consume a web service in ABAP (on a WAS 7 box) and have read many blogs/posts about using a proxy object.
I've gone to SE80 and selected create a service consumer, enter the URL for the WSDL.
The generation of the proxy fails with the following messages;
Proxy-Generierung: Fehler aufgetreten
Exception occured in the library handler
not implemented
There is no other help or information in these errors.
Does anyone have any ideas on what is causing this and what I can do to successfully generate a proxy to consume the web service ?
Cheers
James

Hello Torsten,
It seems that the Web Service You are going to consume is a SOAP 1.2 one.
It is apparently making use of the so-called "SOAP Web Method Feature" which is part of the SOAP 1.2 specification (see [Web Method Feature (W3C)|http://www.w3.org/TR/soap12-part2/#WebMethodFeature]).
Unfortunately, SOAP 1.2 is, to the best of my knowledge, not supported as yet by the SOAP Adapter in SAP NW 7.0 / 7.1. That leaves You, in theory, with one of the following options:
- It might be possible to consume that service with the help of Axis framework (see [Using the Axis Framework in the SOAP Adapter|http://help.sap.com/saphelp_nw04/helpdata/en/45/a4f8bbdfdc0d36e10000000a114a6b/frameset.htm]). SAP Help states that with the help of the Axis framework SOAP 1.2 can be used. However, there are no further details on that subject, especially whether Web Method feature can be utilised (btw - has anyone tried this?).
- Ask service provider for a SOAP 1.1-compatible WSDL.
- Attempt to reverse engineer the SAP SOAP proxy so that it is capable of consuming a SOAP 1.2 Web Method-based web service (has anyone done this before?).
Would You be so kind to post whether, and how, You were able to consume this web service?
Kind regards

The Proper way to go - Passing Serialized Java Objects vs. Web Services?

The team which I am apart of in our little "community" is trying to convince some "others" (management) that we should not use web services to communicate (move large data) within the same application (allbeit a huge application spanning across many servers).
Furthermore these "others" are trying to tell us that in this same application when two small apps. inside of this large app. are both java we should not communicate via serialized java objects but instead we should use Web Services and XML. We are trying to convince them that the simplest way is best.
They have asked us to provide them with proof that passing serialized java objects back and forth between two smaller java applications inside of a larger one is an Industry Standard. Can anyone help either straighten my fellow workers and I out or help us convince the "others" of the proper way to go?

When I was a consultant we always gave the client what they wanted. Even if it was the wrong choice. Suck it up.
I'm glad I wasn't one of those customers. Although I agree that a customer is the one who decides what to do, when I pay someone for consultancy, I expect them to consult me. If they know I'm trying to do something that I shouldn't be doing, I expect a good consultant to be able to show me that there's a better way (not just tell me I'm not doing it right, mind you).
We pass a lot of data using XML and we don't have any transmission or processing speed issues.
Then you either have a much better network than our customer did, or we're not talking about the same amounts of data here.
I used the JAX-RPC RI ...
That's cool... our customer was, unfortunately, infected with Borland products, so we had to use BES. The web services on BES were run by Axis.
How large were these messages?
Huge... each element had about 15 attributes, so 1,200 elements would require 19,200 XML nodes (envelope not included). By comparison, the serialized messages weren't even a quarter that size. It's not just about what you send across the network; it's also the effort of parsing XML compared to desrializing Java objects. Our web service wasn't exactly the only process running at the server.
Anyone who understand the fundamental difference between ASCII (XML) and binary (serialized) formats realizes that no web service can possibly achieve the performance of binary Java services. Why do you think that work is being put into binary web services? I'm not saying XML is never a good thing; just that it's not The Holy Grail that a lot of people are making it look like.

Retrieve error message of SAP provided web service in web service response

Hi All,
We have a SAP provided web service that sometimes fails to process data it is called with. This is not a problem as the data sometimes is just plain wrong (i.e. date field contains text). However, the error is only logged in SAP and can only be queried using SRT_UTIL.
The problem is that the error is not reported back via the response. How can we set up the web service so that the error could be displayed by the calling party without logging into SAP?
Thanks for the help in advance.
Best Regards,
Daniel

Hi Calvin,
The WS is indeed synchronous. The problem is not whether the error is captured or not. It is captured indeed but it is logged inside SAP only and not returned via the Web Service response mechanism. The error message says that error message can be retrieved using SRT_UTIL.
This is a major problem as the users of the outside system calling SAP have no right to use SRT_UTIL to track down the error. They need to contact SAP basis in order to get to the end of it.
What we need to achieve is to get back the same error message that can be seen with SRT_UTIL via the web service.
Thanks.
