Read Web Service Response

Hello,
I am really new to the IT field and just got the task of reading Web Service data and then write it into an SAP table. As a first task, I started off by calling a web service from SAP. To do that, I have followed the several tutorials that I found on the posts, which is basically the following:
1. Call the service description.
2. Generate a WS client proxy.
3. Create a logical Port.
4. Implement the client application.
I went through these for steps successfully I believe; however, I did not get any visible data from the Web Service. I guess it was because I did not send any type of query to get the response nor did I include a command to display it.
The web service I am trying to call is
The WSDL file I am trying to get information from is [http://www.webservicex.net/stockquote.asmx?wsdl].
The code I am using is:
REPORT Z_WEST_029_WSPROXY.
DATA: proxy TYPE REF TO ZES_CO_STOCK_QUOTE_SOAP,
      in    TYPE ZES_GET_QUOTE_SOAP_IN,
      out   TYPE ZES_GET_QUOTE_SOAP_OUT.
TRY.
    CREATE OBJECT proxy
EXPORTING
    LOGICAL_PORT_NAME = 'STOCK_QUOTE'.
CATCH CX_AI_SYSTEM_FAULT .
ENDTRY.
TRY.
CALL METHOD proxy->GET_QUOTE
EXPORTING
    INPUT = in
IMPORTING
    OUTPUT = out.
CATCH CX_AI_SYSTEM_FAULT .
CATCH CX_AI_APPLICATION_FAULT .
ENDTRY.
As far as sintax the program works correctly, but after I successfully run it no results are displayed.
Do I have to declare input variables??
How can I display the results??
I kindly accept basics and simple explanations as I am very new to this.
Thanks a lot in advance!

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 ???

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 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

Hi
Have you found the workaround?
Sorry for refreshing topic. Flag mustUnderstand ='1' in response is unussual thing.

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,

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.

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:<< "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:<< "</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:<< "[\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 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: 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).

Web Service Response truncated

Hi out there,
I finally got a web service reference to Amazon's ECS up and running.
But the response from the web service is not put into a collection. IF I debug my application I see that Amazon is responding and that the response is truncated.
If I view the collection's session state I get the error message: character buffer too small ...
Is there any possiblity to store the response from a web service in a CLOB or XMLType item, so that the parsing can take place ?
Regards Markus

I use web services a lot and I sympathize with your issue. I
struggle with similar issues and I found this great utility that
will help you confirm if your webservice is returning the data
correctly to Flex. I know you said it works in other applications
but who knows if flex is calling it correctly etc. This utility is
been the most amazing tool in helping me resolve web service
issues.
http://www.charlesproxy.com/
Once you can confirm the data being returned is good you can
try several things in flex. Try changing your result format to
object or e4x etc. See how that plays out. Not sure where your
tapping in to look at your debugger, you might want to catch it
right at the result handler before converting to any collections. .
If nothing here helps maybe post some code to look at. .

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!

Not able to receive the web service response to java client - jax-rpc

HI,
Have a wsdl and created the java client using wscompile and got the set of files (Port, Binding, ServiceLocator, Service and all related java files).
My java client sends the valid java request to the webserver and i could see the correct response coming back to my machine as the reply from the webserver.
But i couldnt get the response printed using System.out.println in my java client when i invoke call.invoke() method with needed input parameters.
Do i need to set any encoding or how do i get the response in the my java client which is returned from the webserver?

Potential Memory Leak during Marshelling of a Web Service Response

I believe I have found a memory leak when using the configuration below.
The memory leak occurs when calling a web service. When the web service function is marshelling the response of the function call, an "500 Internal Server Error ... java.lang.OutOfMemoryError" is returned from OC4J. This error may be seen via the TCP Packet Monitor in JDeveloper.
Unfortunately no exception dump is outputted to the OC4J log.
Configuration:
Windows 2000 with 1 gig ram
JDeveloper 9.0.5.2 with JAX/RPC extension installed
OC4J 10.0.3
Sun JVM version 1.4.2_03-b02
To demonstrate the error I created a simple web service and client. See below the client and web service function that demonstrates it.
The web service is made up of a single function called "queryTestOutput".
It returns an object of class "TestOutputQueryResult" which contains an int and an array.
The function call accepts a one int input parameter which is used to vary the size of array in the returned object.
For small int (less than 100). Web service function returns successfully.
For larger int and depending on the size of memory configuration when OC4J is launched,
the OutOfMemoryError is returned.
The package "ws_issue.service" contains the web service.
I used the Generate JAX-RPC proxy to build the client (found in package "ws_issue.client"). Package "types" was
also created by Generate JAX-RPC proxy.
To test the web service call execute the class runClient. Vary the int "atestValue" until error is returned.
I have tried this with all three encodings: RPC/Encoded, RPC/Literal, Document/Literal. They have the
same issue.
The OutOfMemory Error is raised fairly consistently using the java settings -Xms386m -Xmx386m for OC4J when 750 is specified for the input parameter.
I also noticed that when 600 is specified, the client seems to hang. According to the TCP Packet Monitor,
the response is returned. But, the client seems unable to unmarshal the message.
** file runClient.java
// -- this client is using Document/Literal
package ws_issue.client;
public class runClient
public runClient()
* @param args
* Test out the web service
* Play with the atestValue variable to until exception
public static void main(String[] args)
//runClient runClient = new runClient();
long startTime;
int atestValue = 1;
atestValue = 2;
//atestValue = 105; // last one to work with default memory settings in oc4j
//atestValue = 106; // out of memory error as seen in TCP Packet Monitor
// fails with default memory settings in oc4j
//atestValue = 600; // hangs client (TCP Packet Monitor shows response)
// when oc4j memory sessions are -Xms386m -Xmx386m
atestValue = 750; // out of memory error as seen in TCP Packet Monitor
// when oc4j memory sessions are -Xms386m -Xmx386m
try
startTime = System.currentTimeMillis();
Ws_issueInterface ws = (Ws_issueInterface) (new Ws_issue_Impl().getWs_issueInterfacePort());

I use web services a lot and I sympathize with your issue. I
struggle with similar issues and I found this great utility that
will help you confirm if your webservice is returning the data
correctly to Flex. I know you said it works in other applications
but who knows if flex is calling it correctly etc. This utility is
been the most amazing tool in helping me resolve web service
issues.

Once you can confirm the data being returned is good you can
try several things in flex. Try changing your result format to
object or e4x etc. See how that plays out. Not sure where your
tapping in to look at your debugger, you might want to catch it
right at the result handler before converting to any collections. .
If nothing here helps maybe post some code to look at. .
