OSB call to remote Web Service via https proxy and https CONNECT problem

Hi
I have a service that calls a web service on another server as a web service. This call is via https and the certificate validation raises no errors.
I now want this call to go via a squid httpd proxy on port 3128 on some machine. So I would like to use HTTP CONNECT (RFC 2817) proxying,. But when I set up this as a proxy, I am getting "Certificate chain" error messages. The certifcate chains is no different now from when I called without the http proxy, so what am I doing wrong? Does OSB support HTTP CONNECT?
-Johan

The exeption we are getting is BEA-380000
General runtime error: [Security:090477]Certificate chain received from XXX - 123.123.123.123 --> test.salesforce.com was not trusted causing SSL handshake failure.
This is of course not relevant if the callout were using CONNECT. In the CONNECT scenario, OSB would not care about XXX's certificate.

How to call a secure web service via XAI Sender in CC&B

Hi All,
I want to a call a secure web service from CC&B through out bound message. I have configured the calling WSDL in XAI Sender. The wevservice is secured one.I tried to call it by configuring user name and password in XAI sender context.But still i am not able to call the service.
Can anybody help me how to over come this issue ??
I have cretaed the same post under utilities,but i am not able reply it.
I am using HTTPSNDR as XAI class.
Thanx in advance.
Regards
sunil

Are you getting any errors? What type of XAI Class are you using?
One thing I've noticed is that if you are making changes to the XAI Sender you will have to restart the environment before the changes can take effect.
Also, if you are using RTHTTPSNDR as XAI Class you may have to include the HTTP Method - Post in the context.
Hope this helps.

Browser based InfoPath form deployed on a Claims based Web Application calling a Secure Web Service via Data Connection

hi,
We have a Browser based InfoPath Form deployed on a Claims based Web Application. We are tyring to call WCF Services that are secure using Certificates via the Data Connections on Infopath Form.
Earlier we used to get the Data in BCS External List via the WCF Services and the Data Connections used to get the Data from the BCS External List. Due to Performance Issues, we want to remove the BCS External List and straightaway call the secure WCF Services
via the Data Connections.
Have anyone implemented this scenario.
Thanks
Ram
Thanks Ram

Hi Ram,
As these are browser based InfoPath forms, you have two options
1) Deploy as sandboxed forms
In this case you have to create a secure store application id and then set the credentials for that account.
You then have to export the data connection to Data connections library and modify the .udcx file to utilize the newly created secure store application id.
This may sometime give issues related to sandboxed code service. You have to give permissions on the secure store for the user account which the sandboxed code service is running.
2) Deploy as administrator approved forms
This would be ideal way of doing things as you have full control over the web request if you write code behind InfoPath forms.
3) Deploy as a Hybrid solution
a) Write a full trust proxy solutions (extend SPProxyOperation class and override execute method) and make the web request call inside this and return the response
b) Invoke above operation from the sandboxed InfoPath form's code behind by SPUtility.RegisteredProxyOperation(four part assembly name, operation args)
Hope this helps.
Thanks,
Srikanth

Problem in calling XI generated Web Service via Java Web Dynpro

Hi experts,
I have problems with calling a web service, which was created by XI. I have already tested the web service with Altova XMLSpy. The Web Service works fine.
But when embedding this web service into Java Web dynpro application no message flow is given. I have two views one Selection View and one Result View which should show the answer sent by RFC-Call.
<b>My Settings in NWDS:</b>
During configuration of web dynpro I have choosen 'Import adaptive Web Service Model' --> Select wsdl file via local file system --> 'no logical destinations - use WSDL URL for metadata retrieval and web service execution'.
The model is also not shown in diagram view although I have added into the diagram.
The web service was created on XI 7.0.
Should I do any other settings e.g. in Visual Administrator, Web Dynpro Content Administrator?
So can anybody help me.
Thanks a lot.
Regards,
Mario

Hi Aviad,
thanks for your fast reply.
But in Web Service Navigator my Web Service is not shown, because I used the SOAP Adapter.
<b>My Web Service link:</b>
http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=:SRV_GBD_WS_GET_DEB_DETAIL:CC_GBD_WEBSERVICE_SENDER&version=3.0&Sender.Service=&Interface=%5E*
During executing Web Dynpro I got following errors:
1. 'The system cannot find the path specified'.
2. com.sap.tc.webdynpro.model.webservice.exception.WSModelRuntimeException: Exception on creation of service metadata for WSDL URL

Consuming stateful web service via ABAP proxy

Hi all,
I´ve got the following scenario. I´ve a ABAP proxy generated based on a WSDL file. The provider is a WebService provided by a tomcat server. (no PI etc. as middleware). The problem i´ve now is that the webservice is stateful so I need a stateful communication between my ABAP report (client) and the Web Service.
I´ve already found the possibiliy to switch on the feature "Session-Oriented Communication" on "Preconfiguration Tab" of the ABAP Proxy Screen. But unfortunately it´s not working.
Anybody knows whether general system settings has to be changed for this. Or anybody has other tips.
I´m currentliy working on the SAP Discovery System v3 which is a Netweaver 7.0.
Many thanks in advance for your answers,
Andy

Calling web service via SSL

Hi,
I do not succeed in calling a web service via SSL from within a Web Dynpro application.
Current settings of my logical port:
Target Address: https://...
Authentication: HTTP authentication, basic (username/password)
I do call methods _setUser and _setPassword to set userid and password before calling method execute() of my modelclass.
On calling method execute(), I get message "Connection closed by remote host".
Any suggestions ?
Many thanks.
Jorgen

Can you check the following?
1) Did you install the SAP Cryptographic toolkit for Java available from service.sap.com?
2) Did you install the "Java Cryptography Extension (JCE)
Unlimited Strength Jurisdiction Policy Files 1.4.2". For Sun they are available here: http://java.sun.com/j2se/1.4.2/download.html (last item on page)
3) How is the SSL server configured? Does it require client authentication? In this case you must send a client certificate.

401 HTTP Response for remote web service portlet

Hi, I am trying to configure IIS web page in ALUI as a remote web service portlet. I have used one of the help HTML pages of IIS server to configure portlet.
http://localhost/IISHelp/iis/htm/core/iiwltop.htm
However, I am getting 401 http response error (You are not authorized to view this page) when i view the portlet. The same URL above works fine if I open in a stand alone browser. Could any one of you help in resolving this please?
Thanks
Sampath

Hi, thanks a lot for your help. I am using windows XP professional. When I set my directory security & grant anonymous access to IUSER the default help site also not coming up, i am geting 401 error.
When I checked the option Integrated Windows Authentication, then in Internet Explorer the help pages are coming up with out asking for user name and password. I installed firefox and checked. In Firefox, a prompt was coming to fill user name and password. I filled in my local windows authentication details and the page was working.
I provided the windows login details for the remote server in Administrator's basic acuthentication information. I was still getting the same error (401 error). Then I went to IIS, drectory security settings and checked Basic Authentication(password is sent in clear text) & unchecked Integrated Windows Authentication, the website pages in IIS were showing up in ALUI. WIth this, my problem is half solved.
The next problem is, I have siebel analytics web application running on IIS. This website requires user name and password if i have to access any report (say). It automatically redirects to my login page. Now I do not want portal user to enter the login details again for accessing siebel reports. But since I have two authentications (now) one for IIS and one for Siebel reporting website, any one know how to configure this?
I was trying to configure different authentication in web service that i was creating in ALUI, but siebel website authentication information I am providing in web service is overriding the IIS authentication and I am getting 401 error (initial problem). I appreciate any auggestions.
Thanks a lot in advance.

WWSAPI - Cannot connect to web service via SSL and HTTP proxy authentication with NTLM, errorCode 0x803d0016, HTTP status 407

Hi,
I built a web service client using WWSAPI. The connection works via SSL (without HTTP proxy) and it works with SSL and proxy with basic authentication as well. When I try to connect using a proxy with NTLM authentication, then I get the errorCode
0x803d0016, HTTP status "407 (0x197)", "Proxy Authentication Required".
In WireShark I see only one HTTP request to connect to the proxy with NTLM Message Type: NTLMSSP_NEGOTIATE. The HTTP Response returns Status 407 and the connection ist closed. Comparing this to Internet Explorer - the Connection is not closed and
a second request with NTLMSSP_AUTH is sent.
Why doesn't it make the complete NTLM handshake? Why wasn't sent the NTLMSSP_AUTH directly?
I oriented in the HttpCalculatorWithKerberosOverSslClientExample.
Using WS_HTTP_HEADER_AUTH_SECURITY_BINDING,
WS_SECURITY_BINDING_PROPERTY_HTTP_HEADER_AUTH_SCHEME was set to WS_HTTP_HEADER_AUTH_SCHEME_NTLM, WS_SECURITY_BINDING_PROPERTY_HTTP_HEADER_AUTH_TARGET to WS_HTTP_HEADER_AUTH_TARGET_PROXY. I tried WS_DEFAULT_WINDOWS_INTEGRATED_AUTH_CREDENTIAL_TYPE but also WS_STRING_WINDOWS_INTEGRATED_AUTH_CREDENTIAL_TYPE.
Any idea?
Thanks

Invoke existing DotNet web services via B1IF soap call

Hi All,
I have developed my own B1IF web services and invoked them with dot net.
I now want to invoke existing hosted web services via B1IF (Not B1IF Web Services).
Can someone guide me using the Web Service Call (soap call).
Can I invoke any web service via B1IF scenarios (Web Service Call) ?
Kind Regards,
Brenden Draper

Hi Bastian,
I read about it for some reason I get the following error when loading the wsdl:
Can you maybe tell me why I get this ?
I can access the wsdl via my browser perfectly.

Error during connection to https web-service via proxy-server

Hello!
I have created Web Service Proxy using wizard in JDeveloper. Then added some code for authorization on my corporate proxy server.
Then I was trying to connect to two different web services
- first one was HTTP web-service - successful
- second one was HTTPS web-service - failed with error :

Although if i switch off proxy server everything works perfect (both HTTP and HTTPS web-services).
What could be the problem with?

Hi Kenneth,
At the moment, SALT does not support the configuring of an outbound proxy server. I suspect you could use a transparent proxy server, i.e., a proxy server/router combination that proxies outgoing requests, although this isn't something we have tested. My suggestion would be to open a support case and ask for this enhancement. I think it is a reasonable thing for SALT to support.

Return NULL when invoke Web Service via UTL_DBWS

Hi all,
right now, i'm using UTL_DBWS to acces Web Service via database.. but when i'm trying to get data from WEB SERVICE, using utl_dbws.invoke , i got NULL value.
It happened if The result more than Varchar2 / 32767 byte.
i'have tried to change code by :
result := sys.utl_dbws.invoke(l_call, l_input_params);
P_clob := sys.anydata.accessCLOB(result);
The Output IS NULL value even if the data was less than Varchar2 or 32767 byte..
this is my script looks like ::
declare
service sys.utl_dbws.SERVICE;
l_call sys.utl_dbws.CALL;
result ANYDATA;
wsdl_url VARCHAR2(1024);
service_name VARCHAR2(200);
operation_name VARCHAR2(200);
input_params sys.utl_dbws.ANYDATA_LIST;
p_out VARCHAR2(32767);
p_xml XMLTYPE;
p_clob CLOB;
begin
wsdl_url := 'http://127.0.0.1/Exercise/WSDL2.php?wsdl';
service_name :='{urn:hellowsdl}hellwsdl';
operation_name := 'getData';
service := sys.UTL_DBWS.create_service (
wsdl_document_location => URIFACTORY.getURI(wsdl_url),
service_name => service_name);
l_call := sys.utl_dbws.create_call(
service_handle => service,
port_name => null,
operation_name => operation_name
input_params(1) := ANYDATA.ConvertVarchar2('DOCCODE');
result := sys.utl_dbws.invoke(l_call, l_input_params);
p_out := sys.anydata.accessVarchar2(result);
sys.UTL_DBWS.release_call (call_handle => l_call);
sys.UTL_DBWS.release_service (service_handle => service);
end;
Thanx for Any Help

The basics are simple:
- format a valid SOAP envelope
- use UTL_HTTP to make the call
- process the response (typically XML output)
