XQuery to optimize Web Service response

This is a question about the use of XQuery. I worked with an individual that said they utilized quite a few Web Services in their application that produced a massive amount of results. In some scenarios, all the results were needed and other scenarios, more minimal results were needed. Instead of implementing new methods to be available through the Web Service, they would allow developers to send an XQuery that would be applied to the response before the reply was sent, to allow filtering of the results. Does this sound like something XQuery could be used for? And does it seem like this would be beneficial in an architecture, or is it better just to create multiple methods available through the web service that developers would call individually?
Thanks

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 ???

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

Hi
I have a requirement where in I have to consume a web service as adaptive web service model, and while executing the service pass a mandatory parameter to the soap header. We are able to set the mandatory parameter to the soad header. We got the code snippet to do this from a wiki link
http://wiki.sdn.sap.com/wiki/display/WDJava/FAQ-Models-AdaptiveWebService#FAQ-Models-AdaptiveWebService-WhatarethefunctionalgapsofthecurrentAdpativeWSModelImporter%3F
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.
Thanks,
KN.

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.

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.

Web Service Response Customization

Hi There !
I wonder if it is possible to manipulate the pattern of response of the operations exposed by the OSM Web service .
For example by invoking the operation CreateOrder which responded me
<xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> <env:Envelope
<env:Header/>
<env:Body>
xmlns:n1="http://xmlns.oracle.com/communications/ordermanagement"> <n1:CreateOrderResponse
<n1:OrderSummary>
<n1:Id> 12 </ n1: Id>
<n1:Specification>
<n1:Cartridge>
<n1:Name> ncaOsmFactibilidad </ n1: Name>
<n1:Version> 1.0.0 </ n1: Version>
</ n1: Cartridge>
<n1:Type> ncaOsmFactibilidadOrder </ n1: Type>
<n1:Source> ncaOsmFactibilidadOrder </ n1: Source>
</ n1: Specification>
<n1:State> open.running.in_progress </ n1: State>
<n1:Reference> 17-12C96Z </ n1: Reference>
<n1:Priority> 5 </ n1: Priority>
</ n1: OrderSummary>
</ n1: CreateOrderResponse>
</ env: Body>
</ env: Envelope>
I would like to modify the response to include new custom elements
Regards

Hi Andres;
We do not support the ability to enrich the Create Order response message in the way that you are describing below, however you may be able to make use of order lifecycle notifications to be able to generate a custom event out of OSM when an order is created. To do this, you would automate the order state change or order create even with an automated notification plugin, and then have it send a jms message on the queue/topic of your choosing and format it how you wish using xquery/xslt/java (just as with a task automator).

How can prevent http chunks receiving in a web service response?

Hi guys,
I'm developing a WS client mobile application, which consumes a Web Service (java based).
Usually it works fine, but sometimes in the clinet I get: java.rmi.MarshalException: Unexpected Exception : unexpected end of stream
This error occur when some big data has to be received from the server.
I've done some research on this problem and find that this is caused because of sending of th response via HTTP chunks. Somehow the server and client sides does not
communicates as expected.
I have no access to the Web service implementation.
Is there a workaround to solve this problem on the client side?
Can I force WS client to not receive the response in http chunks?
Thanks

I managed to fix it by using the well known pattern:
Web Service on the server(1) <--> Web Application(2) <--> Mobile Client(3).
For communication between (1) and (2) was by using WS, and between (2) and (3) was made by plain http connection. Now the application is portable and don't have any limitations.
radarada, thanks for the advice. It may work, may be I can try it when I have some time.

Return Table empty in Web Service response

Hi All,
My Question is more of related to Web Service. I have created a Web Service from ABAP for BAPI_PO_GETDETAIL. This BAPI is working fine in R/3.
I am using this particular Web Service in Adobe Form (using only ADOBE LIVECYCLE Designer). It's is working fine If i pass the correct Data(Purchase order no.) I'll get the O/p. In case I put a wrong PO number I am not getting the values in return Table in response. (If i test the BAPI in R/3 i m getting a message in Return table that PO no. doesn't exist)
Any Help will be appreciated.
PS; I m using Adobe liveCycle designer 7.1 and Acrobat Professional 9.
Regards,
Sachin

Hi,
It is sufficient to make changes in the WebService Definition.
I communicated wrong entries, do make changes like: follow the previous steps and goto the se80 to respective webservice and do make changes in both External View and Internal View, as when you go into these views you'll find under some node "Input" and "Output", here need to do changes in tables present in the "input" and "output" as when you go into "input" or "output" to a respective table there you'll find two sections "External" and "Abap" do edit in Section "External" as Check the checkbox "Exposed" and Uncheck the checkbox "Optional" also "Min Occurr" should be "1" and "Max occurr" should be unbounded.
Make sure in the Adobe Form, for the button which you are calling the webservice, goto the object pallette of that button and goto execute tab and there check the checkbox "Re-merge form data" or if you are invoking the webservice through scripting then you make change the script like"......execute(1)...".

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
Date: Fri, 05 Jul 2013 17:06:41 GMT
Server: Apache-Coyote/1.1
X-Powered-By: None

Access-Control-Allow-Origin: *
Connection: close
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"><soap:Body>.................</soap:Body></soap:Envelope>
Service 2 Raw Response:
HTTP/1.1 500 Internal Server Error
Date: Fri, 05 Jul 2013 17:05:14 GMT

--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!

Differing Web Service responses between 10.1.3.3 and 11g

In our production environment we have deployed several ESB projects. I am currently going through these projects and attempting to update them to 11g. These projects follow the same basic design. In the 101.3.4 environment they consist of an exposed routing service generated from a schema document which routes to a Web service adapter. The exposed service is called from our asset management system the service adapter is invoking a PeopleSoft Asynchronous one way web service. In 11g this became two web service adapters (the first as an exposed one-way service) linked by a mediator.
In our 101.3.4 environment this process worked without exceptions. After upgrading the project our asset management system would raise an exception after each call to the exposed service. Interestingly I can check em and also PeopleSoft and the payload is successfully delivered. When I review the instance in em there are no faults or exceptions. I have auditing turned on and can see that the service, mediator and reference steps have all successfully completed. When I look at the log for the particular instance I do receive a warning which states:
Error parsing envelope: most likely due to an invalid SOAP message.: Unexpected EOF in prolog\r\n at [row,col {unknown-source}]: [1,0]
I used soapUI to debug the service calls. If I call the PeopleSoft web service without using the mediator project I receive the following response:
Tue Aug 18 20:55:37 PDT 2009:DEBUG:<< "HTTP/1.1 200 OK[\r][\n]"
Tue Aug 18 20:55:37 PDT 2009:DEBUG:<< "HTTP/1.1 200 OK[\r][\n]"
Tue Aug 18 20:55:37 PDT 2009:DEBUG:<< "Date: Wed, 19 Aug 2009 03:57:01 GMT[\r][\n]"
Tue Aug 18 20:55:37 PDT 2009:DEBUG:<< "Content-Length: 0[\r][\n]"
Tue Aug 18 20:55:37 PDT 2009:DEBUG:<< "Content-Type: text/xml; charset=UTF-8[\r][\n]"
Tue Aug 18 20:55:37 PDT 2009:DEBUG:<< "X-Powered-By: Servlet/2.4 JSP/2.0[\r][\n]"
When I call the exposed service in my 10.1.3.4 ESB project I receive the following response:
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "HTTP/1.1 200 OK[\r][\n]"
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "HTTP/1.1 200 OK[\r][\n]"
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "Date: Wed, 19 Aug 2009 03:57:25 GMT[\r][\n]"

Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "Content-Type: text/xml;charset=utf-8[\r][\n]"
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "X-Powered-By: Servlet/2.4 JSP/2.0[\r][\n]"
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "[\r][\n]"
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">[\n]"
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< " <soapenv:Body/>[\n]"
Tue Aug 18 20:57:26 PDT 2009:DEBUG:<< "</soapenv:Envelope>"
You will notice that what is returned is a soap envelope which has an empty body.
If i then make the call through the 11g exposed service I get the following response:
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "HTTP/1.1 202 Accepted[\r][\n]"
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "HTTP/1.1 202 Accepted[\r][\n]"
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "Date: Wed, 19 Aug 2009 03:58:46 GMT[\r][\n]"
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "Content-Length: 0[\r][\n]"
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "Content-Type: [\r][\n]"
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "X-ORACLE-DMS-ECID: 0000ICkncqY0bq3pzk8DyW1ANuRl000035[\r][\n]"
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "X-Powered-By: Servlet/2.5 JSP/2.1[\r][\n]"
Tue Aug 18 20:58:46 PDT 2009:DEBUG:<< "[\r][\n]"
I believe the exception being thrown by the asset management system is a result of the zero length, empty content-type being returned from my mediator service or possibly the fact that the return code is 202 as opposed to 200.
First I would like to know if anyone has experienced the same behavior and whether this behavior is by design. Is a response required from all services even if they are one way?
Second if this is by design is it possible within the mediator project to force a return code of 200 and a response that includes an empty soap envelope?
Of course any other solutions are welcome as well. I am leaning towards a solution which can be implemented within my mediator project as I have much more flexibility there then either of the other participating systems.
Thank you very much.

After exploring this issue with Oracle Support and doing some of my own research I believe that the issue is not the SOA Suite but rather the third party system which was calling exposed service in the SOA Suite. According to the link below both the response returned from the 10.1.3.4 esb project and the 11.1.1.1 mediator project are valid. What is returned from calling a one-way service appears to be up to the implementer of the service.
http://www.w3.org/TR/2006/NOTE-soap11-ror-httpbinding-20060321/
"This SOAP 1.1 request optional response HTTP binding, in conjunction with the SOAP 1.1 binding [SOAP 1.1], can be used for sending request messages with an optional SOAP response. This binding augments the SOAP 1.1 binding by allowing that the HTTP [RFC 2616] response MAY have a 202 status code and the response body MAY be empty. Note that the HTTP [RFC 2616] specification states "the 202 response is intentionally non-committal" and so any content in the response body, including a SOAP Envelope, MAY not be an expected SOAP response"

Removing xmlns from web service response issue (XSTL mapping)

Hi XI experts.
I'm having a very strange issue with a pamming program: It all started because the response from a 3rd party web service is coming with a "xmlns=http://....etc" in the document node and this was causing XI not to recognize the message.
After reading most of the forum threads and with the help of other web resources, I was able to write a small XSLT program to remove this. The program seems to work perfectly: I can open the resulting XML document in IE, return it as a response to a test soapUI call, even load it all in "green" in the XI mapping test tool.
But, when I feed the resulting message into the next mapping (XI mapping), only the Message Type node is produced at the other end!!! Not even an error message is issued. The same happens in the mapping test tool. Hoewver, I'm able to display the queues. I'm puzzled.
This is my XSLT mapping, is there anything wrong with it?
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:for-each select="@*">
<xsl:attribute name="{local-name()}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:for-each>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Thanks in advance.
Carlos

Hi Aamir,
Thanks for your response. I will check it out.
In the last 10 minutes or so I realized that the empty message is being produced because the first child node of the message is optional (0..1) and for some strange reason that source node mapped to it was not being recognized after the XSLT. I confirmed this by mapping this node to a constant. Then I restored the original mapping and now it's working - weird! It looks like something was messed up inside the XI mapping program. I will continue testing however I am now off-site and have no connectivity via SOAPUI until Monday.
Thanks.
Carlos

Web Service Response Format (1.4 JAX/RPC)

Hi, i have built a WS using a JDeveloper wizard to create a Java (1.4 JAX/RPC)Web Service.
The problem is i need to be very specific about the format of the response. A typical response would be something like
<env:Envelope
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ns0="http://tempuri.org/">
<env:Body>
<ns0:SubmitMessageResponse>
<ns0:SubmitMessageResult>Response String</ns0:SubmitMessageResult>
</ns0:SubmitMessageResponse>
</env:Body>
</env:Envelope>
This is a perfectly accepted example of XML, however the system that makes the call is not happy with the namespace tags.
does anyone know of a way to format the response so it does not use namespacce tags.
The result would be something similar to
<env:Envelope
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://tempuri.org/">
<env:Body>
<SubmitMessageResponse>
<SubmitMessageResult>Response String</SubmitMessageResult>
<SubmitMessageResponse>
</env:Body>
</env:Envelope>
I know this can be achieved by generating a web service that complies to the 1.3 standard, ideally i'd like to avoid this. Additionaly, altering the calling system is not an option.
Many thanks
Chris

Hi,
I cannot confirm whether or not this is a known issue or even a defect. Out of instinct I am building Web Services proxies in their own project because it generates artifacts e.g. for the return types that I don't want to see lying around in my Web Services project. So I assume that it is considered best practices to not put them into the same project to avoid file overrides

Web Service call - XI - SAP and SAP - XI - Web Service response ???

Hi ALL,
Need some guidance on the following Scenario :
A Legacy system would transfer some data to SAP thoruhg a Web Service call and would expect a response from SAP by way of a response to the same Web service call
A synchronous Interface , inbound to sap via a Web service call and back to the legacy system through the response to the same Web Service .
Need to provide WSDL to the Legacy system
Any help on how to do the above mentioned will be apreciated
thanks in advance

SD,
Check this weblog for step by step procedure:
/people/siva.maranani/blog/2005/09/03/invoke-webservices-using-sapxi
Here instead of deploying in XI you will deploy your webservice in the legacy system.
If you want to test this webservice then check this weblog:
