Problems using external web service

I am trying to access an external web service running on tomcat 4.1. have created
a service control from the WSDL of the web service. when i run it with the test
form/xmlbrowser it comes up with this error.
Exception in createInteraction
com.bea.control.ServiceControlException: env:ServerInternal Server Error (unexpected
encoding style: expected=http://schemas.xmlsoap.org/soap/encoding/, actual=)
It has the url as seen in the header below:

Is there some incompatability problems between weblogic8.1 and tomcat4.1

Keith,
can you attach the WSDL you are trying to connect to ?

JCAPS UDDI - Problem Using the Web Service Management Application

Hi everyone, this is my problem:
1.) I installed the JCAPS UDDI Server in a Solaris. <-- Ok
2.) In the eManager I installed the Web Services Access Manager. <-- Ok
3.) I started the UDDI server. <-- Ok
4.) I check that the process is running (in Solaris). <-- Ok
5.) I'm trying to load the Web Service Management Application Login Page, but it doesn't show the page so I can't login and in consequence I can't publish, remove, view, and search WSDLs by using the Web Service Management Application.
I appreciate some help about this.

Using External Web Service

Hello All,
I need to get data from External Web Service.
for example from :
http://www.w3schools.com/webservices/ws_use.asp
I need to use it from SERVER side method for example from any Context Node SET_XXX() method.
Thanks In Advance
Eli

Hi Eli,
You can create a proxy using the external web services. Go to transation SE 80->Edit Object on the application tool bar. Select the Enterprise Services tab and select the client proxy and click create.
select URL/HTTP Destination and just follow the menu path. The external web service will be created as a proxy(class) in SAP. you will be able to use this in your coding.
Hope this helps.

Logical Port Problem using a Web Service

Hi.
I have created a simple web service and imported the model succesfully into my webdynpro component. However, when I execute the web service method, I just get the following error:
"Logical Ports loading problem. Parser error."
I'm new to NWDS, but my application did work when I first used it, because my web service throws an exception and this was displayed correctly in the application.
Could this error be due to Internet explorer connection settings on the Duiscovery server? (We have a few exclusions in there).
If I type in the url of my web service manually into IE on the discovery server, it returns the expected results, so I know my web service is working.
There also seems to be a problem with my NWDS install, because if I change any of the properties of the Logical Port, the save icon isn't available, and shutting the properties page and reopening it restores the original settings.
Any help would be greatly appreciated, as this is driving me nuts!
Many thanks in advance.
Nigel

OK, so I've found the answer to the proxy settings on the client - they are stored in
<InstallDIR>\Workspace\ .metadata\ .plugins\com.tssap.config\pref_store.ini
For no proxy, change the contents of this file as follows:
#Tue Apr 15 10:09:09 ACT 2008
proxyHost=
sapInitialized=true
proxySet=false
applyNoProxy=true
proxyPort=
Then save it, delete the logical port on your model and then create a new logical port from your WSDL.

Stub(Proxy) generation for external Web Service in SAP NW WebAS 6.40

Hi,
Can anyone tell me what tool is used to generate the proxy files for accessing any external web services in SAP NetWeaver WebAS 6.40 for JAVA (SAP DevStudio 2.0.5).
Do i have to install any components or configuration for using external web services?
Thanks,
Mital.

Hi Peter,
Thanks for the reply.
I have already gone through the Email Web Service tutorial. And implemented the tutorila.But no where they have mentioned about the toolkit they are using to generate stub files and SOAP request.(for eg Axis tool for WSDL to java generation).
Also I am facing problems while I am trying to use an external webservice. I have posted the problem at Re: WebDynpro External Web Service Model.
It would be nice if uyou can go through the problem and help me in solving the problem.
Also can you please tell me the link for the mentioned documents on importing web service model.
Thanks,
Mital.

Using an external web service and local element declarations

I am attempting to use (call) an external web service from workshop
8.1. It seems that if the web service's schema contains local element
declarations with the same name then workshop will generate incorrect
JCX code because it doesn't scope the generated classes.
I think the following simple example will do a better job explaining
than that last paragraph ;). In the following WSDL, the element
"testLocalDec" is used inside two different element types. In XML
Schema this is not a problem because each one is "scoped" by the
element types its included in. However, the generated JCX (listed
second) simply contains the testLocalDec structure twice which causes
problems in Java.
Is there some workaround for this? Note that making this element
declaration in the WSDL will not work because they are different
structures (with different names).
Also see my next email around using XMLBeans with external services
(since that could be a workaround if I knew how to do it).
thanks,
dave

Consuming an External Web Service using HTTPS and WS Security

Hello everyone,
I'm having a problem setting the security information in a SOAP header using a generated ABAP Client Proxy to consume an external web service that requires a User ID and Password in the Header section of the SOAP message. I need to use HTTPS. I'm on a WAS 7.01 SP08 system so from my readings, SAP is supposed to be able to add the username and password into the header section of the message. I can't seem to get SAP to add this information added to the header.
Here are the steps that I have taken to set the security values.
1) Created the client proxy from the WSDL in SE80. Basic Authentication on the Configuration tab was turned on automatically.
Note, Transport Security is set to None. I cannot change it.
2) Created an outbound set user name profile in transaction WSPROFILE with the appropriate username and password.
3) Added the profile to the default port in transaction LPCONFIG as an outbound under the WS Security section of the screen.
When I called the external Web Service, I got back the following error message:
com.ibm.wsspi.wssecurity.SoapSecurityException: WSEC5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.
So, after reading through this Forum, I saw that I needed to use the SOAMANAGER. I set up a Proxy in the SOAMANAGER and manually created the Logical Port. This was the only way I could figure out how to set the Authentication Settings in the Logical Port to "User ID / Password". I then entered the User ID and Password.
However, I am still getting the same error message. I feel I am close but missing some small configuration to tell SAP to use WS Security with a Username token.
I'm not sure what I'm doing wrong, so any help would be appreciated.
Thanks,
Stephen

I had this error again so I thought I would post my solution:
The issue is SAP needs to know the certificates being used by the web site being called. These certificates are automatically installed in your browser but need to be manually installed in SAP. This is what I did:
How to find/install new certificates
Make sure you run Internet Explorer as an Administrator so you can export the certificates
Go to the web site that SAP is trying to call in Internet Explorer
Double click on the lock in the address bar
View certificates
Find the certificates that are being used
Tools --> Internet Options --> Content --> Certificates
Click on the “Trusted Root Certification Authorities” tab
Find the certificate identified in step iii
Export as a CER certificate
Click on the “Intermediate Certification Authorities” tab
Find the certificate identified in step iii
Export as a CER certificate
Go to STRUST in SAP
Import the Certificates in the “Anonymous” or “Standard” SSL client
Save
RESTART the ICM via t-code SMICM <-- Critical!!!

External web service problem

I am using CAPS 5.1.2 and I want to use an external webservice.
Importing the external web service from URL or file goes fine.
I decided to do this in a JCD and added the webservice as an OTD.
Building and deployment of my project goes fine, but the server.log gives me the following SEVERE log message:
[#|2007-04-12T12:04:39.418+0200|SEVERE|IS5.1.2|com.stc.wsclient.runtime.ejb.impl.WSClientService|_ThreadID=27; ThreadName=Worker: 13;|environment entries for operation classes are not found in ejb-jar.xmlNo object bound to name java:comp/env/WS_OPERATIONS|#]
and also more info messages like:

     at com.sun.ejb.containers.StatelessSessionContainer.createStatelessEJB(StatelessSessionContainer.java:410)
I can not find any solution to this problem. I also tried to use a Business process instead of a JCD, but I still get the exact same error message.
I have validated the external web service with the "Web Service Definition Editor" and it validates OK.
I am a little bit lost here and do not know where to start debugging this problem. Please help.

Could you please paste your WSDL?

Is it possible to call an external web service using ABAP?

Hi~~
I wonder that is possible to use an external web service in SAPGUI using ABAP without PI ( Process Integraion ).
The external web service means the service that is developed by web-language like ASP.NET.
Thank you.

hi,
i'm trying to study on how to use the oracle bi publisher using another client application aside from oracle. the client application is custom and uses a .Net framework. unfortunately, i am not familiar with how .Net sends requests to oracle bi publisher so i was thinking that may be i can just create oracle pl/sql stored procedures that can send this requests over to bi publisher.
p.s. when you said concurrent manager, i'm not sure if you are referring to oracle apps concurrent manager but if you are, unfortunately i won't be using oracle apps with bi publisher.
thanks

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

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.

SOAPFault

Issue with calling an external web service using web service proxy

Hi,
I've created several web services using JDeveloper succesfully in the past, however I'm getting an issue with one that was working ok previously. Have spoken to the developers of the external web service and they say they haven't changed anything. Also if I test the external web service through soapUI for example it seems fine so it would seem that the issue is with the autogenerated code created by JDeveloper.
Basically I get the following exception as it sends the request to the external service:
java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Bad Authentication header format: 'Basic realm="Integration Server" encoding="UTF-8"'
Expected "," at position 33
The user name/password appear correct.
JDev version 10.1.3.42.70
Any ideas?
Many Thanks
Gary

Found the answer. Basically I had one proxy web service working and one not both linking to a middle tier written in web methods. THe issue actually ended up being with the web methods code in that the one web service (that was not working) was put together using a backwards compatability mode. Once this was switched back then started working again in JDev.
