ABAP Proxy viewing of historical web service posts - XML files

Hi there
I have developed a web service that posts via an ABAP proxy. The webservice posts successfully. Where do I see the historical XML files of the posts of my executed webservices?

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

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

Proxy Authentication Error in Web Service with SAAJ on Weblogic 9.2 MP3

Hi,
I have encountered a problem with proxy authentication in SAAJ web service (WS) calls on Weblogic 9.2 MP3.
My WS client (which uses SAAJ's SOAP classes) should use a proxy that requires authentication to call the external web services.
However, it does not perform the authentication and receives HTTP Error 407 - Unauthorized.
The reason seems to be that Weblogic's Http Handler (weblogic.net.http.Handler) ignores the proxy authentication.
I was able to work around it by setting sun's http handler explicitly in the WS endpoint URL. Sun's handler (sun.net.www.protocol.http.Handler) makes use of the Authenticator class I provided.
1. Please see my code below and let me know if this is the only solution or if I'm doing something wrong. While testing on Tomcat I did not have to set the handler.
2. I have seen that there are also System properties for http.proxyUser and http.proxyPasword, however if I use these and ommit setting the SimpleAuthenticator, it also fails (with either handler!). An explanation of that is welcome.
Thanks in advance.
Code:
===========================================================
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "localhost");
System.setProperty("http.proxyPort", "808");
//System.setProperty("http.proxyUser", "myuser");
//System.setProperty("http.proxyPassword", "mypw");
Authenticator.setDefault(new SimpleAuthenticator("myuser", "mypw"));
String urlString = "http://someurl:8080/webservice..";
URL endpoint1 = new URL(urlString);
URL endpoint2 = new URL(null, urlString, new sun.net.www.protocol.http.Handler());
SOAPConnectionFactory soapfactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapfactory.createConnection();
connection.call(message, endpoint1); // Gives Exception with HTTP Error 407
connection.call(message, endpoint2); // Works and uses the proxy
For reference:
===========================================================
public class SimpleAuthenticator extends Authenticator {
     private String username, password;
     public SimpleAuthenticator(String username, String password) {
          this.username = username;
          this.password = password;
     protected PasswordAuthentication getPasswordAuthentication() {
          return new PasswordAuthentication(username, password.toCharArray());
}

Sorry for the 3 posts.

Use BizTalk 2006 as a proxy for an external Web Service

Hi
We have a solution that is going to work just as a proxy for an external Web Service.
It works like this:
1. We have a Request-Response receive port that receives the calls for the WS.
2. Different Static Solicit-Response ports that have filters for each method in the WS receive the requests and then send them to the external WS.
3. The response from the external WS is then sendt back to the caller via the Request-Response port in point 1.
This generally works like it should. The only problem i have is when the external WS returns a Fault message. I get this fault from the external WS:
<s:Fault xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>s:Client</faultcode><faultstring xml:lang="nb-NO">Some error message the caller should see.</faultstring><detail><GenericFault
xmlns="http://register.test.com/Common" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><ErrorCode>SomthingWentWrong</ErrorCode><Message>Some error message the caller should see.</Message></GenericFault></detail></s:Fault>
This message then failes on BizTalk and BizTalk returns this Fault message to the caller:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP:Body><SOAP:Fault><faultcode>Microsoft BizTalk Server Negative Acknowledgment
</faultcode><faultstring>An error occurred while processing the message, refer to the details section for more information </faultstring><faultactor>/Hemit.BizTalk.NHN.Position.ws/IPositionService.asmx</faultactor><detail><ns0:NACK
Type="NACK" xmlns:ns0="http://schema.microsoft.com/BizTalk/2003/NACKMessage.xsd"><NAckID>{7AC314FE-2CA3-44AE-8208-180495500481}</NAckID><ErrorCode>0xc0c016b7</ErrorCode><ErrorCategory>0</ErrorCategory><ErrorDescription>There
is an error in XML document (1, 2).</ErrorDescription><ErrorDetail><Fault xmlns='http://schemas.xmlsoap.org/soap/envelope/'> was not expected.</ErrorDetail></ns0:NACK></detail></SOAP:Fault></SOAP:Body></SOAP:Envelope>
So the problem seems to be that the Request-Response port in point one will ONLY accept the real response that is specified in the response schema for that particular method, and not a Fault. And when it receives a fault, it generates its own Fault saying
a Fault message was not expected.
Does anyone know how i can be able to send the actual fault from the external WS all the way back to the caller on the inside?
I know how to do it with an orchestration, but can not figure out how to get it done just with the ports.
Kind regars
John Viggo

Hi John,
Enable Propagate fault message
on the WCF solict –response port.
For the two-way send port, you can choose whether to forward
SOAP fault messages on to the original caller over a solicit-response send port by selecting
Propagate fault message. If this option is not selected, BizTalk Server will generate a NACK. What you see is the NACK.
If it is selected, BizTalk Server will treat the message as a valid WCF response message from the external service and the response message will not be suspended because it is propagated.
Then you need to map the fault message to the actual response in the map. Set this Fault-Message to Caller-Response map in the outbound map of the Requeust-Response port.
In this case of messaging-only scenario, this method shall help in handling the fault message and passing fault details back to the caller. Refer the following articles for more details.

How to use a deployable proxy to consume a web service?

HI Gurus,
I am following this article below which helpfully explains how to create a proxy. So far so good. I have been able to create a proxy. However, the article only describes how to build a proxy.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/70c7d0f7-153d-2a10-5d96-d334b67cd771
In the concluding part of the document the author says "In my next article I will tell you how to use this deployable proxy to consume the web service in web application."
I have looked around the SDN but have not been able to get the next part of this document.
I have a JSPDynpage application which is required to consume a webservice. I want to use this proxt to consume the webservice.
Any help or any other document that explains how to use a deployable proxy to consume a web service will be helpful.
Thanks,
SB

Web Service to xml to bls to xacute query formatting

Hi.
I have a BLS calling a web service which returns a data set in the xMII XML format. I take that output and put it in a xml transaction output property and try to read it with an xacute query. (obviously I will be doing more manipulations to the data in the bls once i get this issue resolved). The query returns a blank page when tested.
OK, so I take the same xml output, and in the same bls use the Write_File action to create an xml file, then use the XMLLoader action to read in that file back into the bls, assign the results of the xmlLoader to the xml transaction output property and try to read that output with an xacute query. I get the data when I test the query.
Now, I don't touch the format between the web service and the file or after I load the file. How come the xacute query can read one transaction output and not the other?
I have taken both transaction propertie values from a trace log and compared the strings and find no difference between the return from the web service and the result of the xmlLoader. I don't want to take the output of the web service and write it to a file just to get in into an xml format that works properly.

I am sure that is the root cause, but how do I do an explicit type conversion without going through the output to file and load xml step? What else is needed?
The return of the Web Service is an XML that contains an XML string in the xMII format. I can look at that string and it looks correct (Though xacute doesn't recognize the string as an xml structure). I can take that string and put it in an XML transaction property and it looks correct (the reference in the BLS is: SqlXml2.SQLXML2Response{/ns1:SQLXML2Response/ns1:SQLXML2Return}). I can take that XML variable and output to a file and then load that file and it actually is correct (though the content of the file and the return string from the web service are identical). So, I can see that the type conversion takes place when I load the xml file but I haven't found the action that will do the type conversion otherwise even though the "conversion" doesn't seem to require changing the content at all. Have I missed something?

Error while posting xml file to URL using URLConnection

Hello everyone,
I am facing an issue from long time related to URLConnection. If this would be resolved by your help then I would be very grateful to you.
One application which posts xml file to URL hangs and after waiting for 5 mins it throws 504 error:
java.io.IOException: Server returned HTTP response code: 504 for URL: http:hostname.
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:715)
Same application is running fine without error on another environment from last 5 years. But on another env it is erroring out from the day 1.
We have many workarounds in place none worked.
I tried to use HttpClient from apache but that too hanged at URLConnection.getInputStream() method call.
App is running on iPlanet web server 6.1 using JDK 1.4.0_03
We still dont know why this program hangs at that particular line in only one env but many times it runs fine. That means 30% of the times it posts xml file without error but 70% times it errors out. So our program logic is to retry until post is successful.
Once this issue is resolved we will remove the logic of trying again and agian.
Please provide inputs.
Thanks,
Nitin

The HTTP response 504 means that the server, acting as a gateway, has not received a response from an upstream server in the time it expected.
I think this is problem is due to the remote server that receives the XML and takes too long to return a response to the local application that posted the XML.
Try HttpClient and set the timeout variable of the HttpClient instance used.
Here http://svn.apache.org/viewvc/jakarta/commons/proper/httpclient/trunk/src/examples/PostXML.java?revision=480424&view=markup
a Post XML sample.
NB: HttpClient > setTimeout method is deprecated. See : http://jakarta.apache.org/commons/httpclient/apidocs/index.html for an alternative
Hope That Helps

Clarification on services-config.xml files for RemoteObject services

I am currently preparing an AMFPHP environment for exchanging
data with Flex and AIR applications. I can connect to the services
via Netconnection, but using RemoteObject won't work.
Documentation for the necessary configuration files
(services-config.xml, remoting-config.xml and the like) is, um,
sparse and seems to be slightly incorrect or misleading at times.
So I'm looking for clarification about
changes in the syntax of services-config.xml · in
examples for Flex 2.01, there are "class" attributes with values
beginning with "flex.", in Flex 3 examples the attribute name has
changed to "type", values beginning with "flex." have mostly
vanished and been replaced with similar looking values beginning
with "mx.". Are "flex." and "mx." prefixes interchangable?
correct syntax for linking other files into
services-config.xml · the livedocs state that Adobe
prefers linking files into services-config.xml (using something
like <service-include file-path="remoting-config.xml"/>)
instead of defining all service parameters there. But in the
example from the Flex 2.01 livedocs, the root element of the
service-config.xml file is <services> instead of
<services-config>. Assuming that <services> is meant as
a
child of the <services-config> root element, there
seems to be a mandatory <service> child element missing.
That's either intended, illogical, and misleading, or simply
erroneous.
which classes are still valid in Flex 3, which have changed?
· Most of the examples for using RemoteObjects out there are
for FlexBuilder 2 (e.g.
here)
and don't seem to work with FlexBuilder 3 Beta 2. But there is no
statement to be found in the Flex 3 documentation about what has
changed.
a meaningful example for services-config.xml · In the
Flex 3 Beta 2 documentation here are plenty of references to using
services-config.xml, as I can find even information about the
ServerConfig class in the ActionScript 3 Language Reference, a sort
of wrapper class for the information provided in
service-config.xml, but there is no information about what
constitutes a
working service-config.xml configuration (which XML tags of
what names containing what attributes need to be present).
As I'd really like to create cutting-edge Flex and AIR OCC
applications, I'm eager to have those ambiguities clarified.
Best regards,
Cathness

From the docs it looks like this is used for web services as
well:
http://livedocs.adobe.com/flex/201/html/dataservices_config_100_3.html#260186
If this isn't the right config file, which file should I be
looking at?

No services-config.xml file

What is the process that installs this file on my server? I
dont have this file in my web directory

are you running flex data services, or just using the Flex
SDK? If you are just using the SDK (or Flex Builder) than you don't
need to have the file on your server. It just needs to be available
during compile-time.
If you are using ColdFusion keep reading...
I included a ColdFusion services-config.xml file below. You
would just need to replace [INSERT YOUR URL] with your actual CF
server URL. You could copy this file locally to your MXML
components and include the path in the compiler options using the
-services "c:\fullpath\to\services-config.xml"
compiler switch.

Resolved! The problem was in the php code the wizard had generated as an example and that I had edited in Dreamweaver. I had tried to start a session and set session objects in the php code. I developed if() { statements} to check the session variable before executing the function in some of my data services. Apparently the wizard does not like this. I removed all references to session. I reconfigured the input types and the return types for each service. With the code now clean the wizard created the example code and placed the proper package in the scr.services package. I still have custom php code and it executes.
Things I learned:
If the php code stops when a session variable is not available in the if statement and the data service is refreshed, the wizard will not "look" beyond the if statement.
Functions downstream of a session variable misshap will show in the data services window but the functions will have a circle icon to the left of the function name and each variable to be passed to the php code will be declared as type = Object in Flashbuilder. The input types and return types will have to be reconfigured for each non-functioning function. Simply commenting out a portion of the php code and attempting a refresh will not make it work again.
When the wizard is unable to refresh properly because of a stop in the php code it stops working completely so additional refreshes or creation of code is not carried out.
I decided to create a My SQL table for user and other identifiers rather than attempting the session object again.
Sorry, I did not make screen shots as I solved this problem. I hope the solution is not hard to visualize.
Thanks for looking and considering how to help me. I hope my solution works for you.

How can the client know if the SSL certificate specified in the service-config.xml file is invalid/u

Hi,
How can the client know if the SSL certificate specified in the service-config.xml file is invalid/untrusted/expired? For example using iOS client, the trusted certificate will not work and the client has no way to know that the certificate is untrusted. Can the lcds server return any specific exceptions for SSL errors?
Thanks,
Swathi.

We use a standard Java keystore and certificate validation can be handled as per standard best practices. At present we do not provide a hook point to validate the server certificate. However, you can register a bootstrap service which validates the certificate on system startup: http://help.adobe.com/en_US/dataservicesjee/4.6/Developing/WSc3ff6d0ea77859461172e0811f00f 6fe7f-7ffeUpdate.html This would require you to pass another copy of the keystore configuration to you Bootstrap service and then you can inspect the certificate in the keystore and validate it.
