How to invoke a web service using https

Hi,
I have a few security related questions surrounding BPEL process manager.
1. Does the BPEL engine have the capability to invoke a web service using https (HTTP over SSL)? Does it automatically do that if partner link URI starts with https:// ?
2. If not, what needs to be done to enable accessing a https based web service?
3. I need to write a web service that accepts a message and updates certain information in the database. The web service will be deployed in an OC4J instance in Oracle App Server. We want to allow the web service to be accessed from BPEL only by users registered in the database. What is the recommended way to pass username and password to a webservice if service is invoked from BPEL process manager? Note that specifying username/password in bpel.xml is not an option.
Thanks,
Pranav

1. Does the BPEL engine have the capability to invoke a web service using https (HTTP over SSL)? Does it automatically do that if partner link URI starts with https:// ?
We currently don't have support for HTTP over SSl. We are working on it to include this functionality in near future.
2. If not, what needs to be done to enable accessing a https based web service?
I am not sure it is possible with current product offering. I will confirm it after discussing with our concerned development group. There is some work going to integrate with Oblix security mechanism [recently acquired by Oracle].

This will be easier to do if we can use Oblix along with BPEL PM. Could you please let us know more about your application so that we can provide you the customized solution till it's part of the product. You can send this query to [email protected] so that our product management team can give you more detailed roadmap regarding this.

How to invoke a web service asynchronously using ws-addressing model?

Hi Gurus,
We are invoking an external web service asynchronously using Oracle Work Flow Business events using the following mechanism -
1)Created a web service invoker event to invoke the web service.
2)Created a subscription that invokes the web service (provided the wsdl address, operation info).
3)Defined a subscription parameter WFBES_CALLBACK_EVENT with value pointing to a recieve event.
4)Created a receive event(parameter value for WFBES_CALLBACK_EVENT) and a subscription that directs the response to a custom PL/SQL function to process response.
so far so good. We were able to invoke the web service and get and process the response.
Problem: The external web service can take upto 10 hrs to process the request. A time out of 2 hrs is set on the server hosting the external web service. So when the external web service takes more than 2 hrs to process the request and it times out and we get the following error on EBS side -
'l_error_message:oracle.apps.fnd.wf.bes.InvokerException: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: oracle.j2ee.ws.saaj.ContentTypeException: Not a valid SOAP Content-Type: text/html; charset=iso-8859-1'
Now the external web service providers are suggesting that we are not calling their web service asynchronously and we should use ws-addressing model to do so.
Is there a way to invoke this web service using ws-addressing model using business events or from PL/SQL or OA middle-tier?
Regards,
Sunil

I am providing here the WSDL of the external web service -

Bharat,
You dont need a Business Event setup to invoke a BPEL process from PL/SQL unless you have a special case and you need to process the response from the BPEL process in a separate thread (or in background)..
For a straight call to BPEL process from PL/SQL, here is a sample script -
function "MYTEST0" return varchar2 AS
soap_request varchar2(30000);
soap_respond varchar2(30000);
http_req utl_http.req;
http_resp utl_http.resp;
resp XMLType;
i integer;
helpStr varchar2(30000);
BEGIN
soap_request:= '<?xml version = ''1.0'' encoding = ''UTF-8''?>

xmlns:ns0="
http://xmlns.oracle.com/TestWS">
<env:Body>
<ns0:TestWSProcessRequest>
<ns0:input>abc</ns0:input>
</ns0:TestWSProcessRequest>
</env:Body>
</env:Envelope>
/* the BPEL process name is TestWS */
http_req:= utl_http.begin_request
( 'http://hostname:7777/orabpel/default/TestWS/1.0'
, 'POST'
, 'HTTP/1.1'
utl_http.set_header(http_req, 'Content-Type', 'text/xml');
utl_http.set_header(http_req, 'Content-Length', length(soap_request));
utl_http.set_header(http_req, 'SOAPAction', 'process');
utl_http.write_text(http_req, soap_request);
http_resp:= utl_http.get_response(http_req);
utl_http.read_text(http_resp, soap_respond);
utl_http.end_response(http_resp);
resp:= XMLType.createXML(soap_respond);

How to access .asmx Web Service using JAVA? Newbie

Hello Experts,
Currently, I have a project where in I have to access a ,NET web service. It is made of C#. I just want to ask how will I start the accessing process? I made this simple equation on how my project is.
Java Project + C#.Net Web Service = Integration
1. Do i need to create a Web Service too for the Java Project? If yes, What are the necessary tools needed for the creation of this Java Web Service?
2. The .NET Web Service is available online. (It is made by other people).
3. Based on the equation, what is the equivalent technology for the + sign?
4. Can you site a concrete example for accessing a web service?
5. I'm new here. Totally I have no idea where to start.
6. Thank you experts.

Hello
Thanks a lot for your help ...
I am developing simple J2EE based web service client using IBM WSAD 5.1. I have used the following code to call .asmx web service in Java
String url = "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl";
     String namespace = "http://tempuri.org/";
     name = request.getParameter("txtName");
     try
          System.out.println("In Internet Service");
          ServiceFactory factory = ServiceFactory.newInstance();
          Service serv = factory.createService(new URL(url),new QName(namespace,"TempConvert"));
          System.out.println("Got Service......");
          Call obj = (Call)serv.createCall();
          System.out.println("Got Call......");
          obj.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,"");
          obj.setProperty(Call.OPERATION_STYLE_PROPERTY,"wrapped");
          obj.setTargetEndpointAddress(url);
          obj.setPortTypeName(new QName(namespace,"TempConvertSoap"));
          obj.setOperationName(new QName(namespace,"FahrenheitToCelsius"));
          obj.addParameter("param1",XMLType.XSD_STRING,String.class,ParameterMode.IN);
          obj.setReturnType(XMLType.XSD_STRING);
          System.out.println("Parameters Set.....");
          Object[] params = new Object[]{name};
          k = (String)obj.invoke(params);
          System.out.println("Result: "+k);
     catch(Exception e)
        System.out.println("Exception is : "+e);
    }But this code is throwing exception that
Invalid Address "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl"I have also tried this URL with Java Proxy. But it showing the same error.
Plz can u tell me how to access .asmx web service ?

Invoking a Web Service using XI 2.0

Hi all,
I am attempting to create a scenario where an SAP application invokes a web service through XI 2.0.
I have created an ABAP proxy to allow my ABAP to start the call process and have set up the message interfaces within the Integration Directory.
I want XI to receive a call from this proxy and then act as the client to an existing Web Service.. calling it and bringing back a response... but it doesn't look like I can import the existing WSDL as a I would have expected.
So... instead I have exported the Message Interface for the "out of XI" portion of the interface as a WSDL and have asked the Web Service provider to amend their service according to this XI generated WSDL.
My difficulty now is how to use the SOAP adapter. Within the Integration Directory I presumably need to define the endpoint with XI Connectivity but I am not sure how to fill in the URL address of the SOAP adapter...
Any help on how to configure the actual SOAP adapter to fulfill this requirement would be great too.
I have looked around the boards to see if I could work this out from previous posts but without success so far.
It's a synchronous scenario and basically should look like...
ABAP Proxy->XI->SOAP Adapter->Web Service->XI->ABAP Proxy
Many thanks,
Gordon

Hi Gordon,
here is an example for SOAP-Adapter config:
# Bubble adapter java class
classname=com.sap.aii.messaging.adapter.ModuleBubble
# Sets the bubble module helper that can instantiate your bubble bag
Bubble.Helper=com.sap.aii.messaging.adapter.ModuleBubbleHelperXMBWSImpl
###### Part 0 (FromWS and ToWS) : common part ######
# Keeps the XMB headers in web service messages
XMBWS.KeepHeaders=false
# Encodes the xmb headers into a special HTTP header string x-xmb_ws_encoded
XMBWS.UseEncoded=false
# The target URL for the web service, to which the adapter sends web service messages.
# The address is part of the WSDL
XMBWS.TargetURL=http://www.extensio.com:8080/ExtensioInfoServer/servlet/rpcrouter
# Proxy configuration from SAP
XMBWS.proxyHost=PrOxY
XMBWS.proxyPort=8080
# The port and path where the adapter waits for XMB messages from clients.
XMBWS.XMBPort=8400
XMBWS.XMBPath=/soap/stockquote
# The default SOAPAction HTTP request header to the web Service server
# The SoapAction is part of the WSDL
XMBWS.DefaultSOAPAction=
Of course you have to set URL, proxy and SOAP-action to your belongings.
You define the endpoint as:
"http://<Adapter-Server>:<XMBPort><XMBPath>"
in this example:
"http://localhost:8400/soap/stockquote"

How to invoke a Web Service from PL/SQL with Complex Type as input.

Hello,
I am trying to invoke a web service from PL/SQL using the UTL_DBWS package.
The web service expects a complex type as input (defined below):
<xs:complexType name="MsgType">
<xs:sequence>
<xs:element name="sender" type="xs:string"/>
<xs:element name="messageId" type="xs:string"/>
<xs:element name="messageType" type="xs:string"/>
<xs:element name="dateSent" type="xs:date"/>
</xs:sequence>
</xs:complexType>
How to construct input to this in PL/SQL Procedure?
Has any body tried this before?
An exmaple will be helpful.
Thanks

The program fails at following line of code -
l_service := UTL_DBWS.create_service (
wsdl_document_location => URIFACTORY.getURI(l_wsdl_url),
service_name => l_service_qname);
Web services are SSL.
The WSDL is at https location and needs username/password for access. The username/password to access WSDL are set using UTL_DBWS.SET_PROPERTY
To access the SSL site, I have imported the CA in Oracle Wallet, JVM home and JDK home.
Can anyone tell me what am I doing wrong here. I am not able to even establish connection to web service host.
This is very frustrating - Oracle has no examples on how to access a SSL Web Service (that needs authentication) from Database.
This is effecting our project deadlines ......... any help would be greatly appreciated.
Thanks.

Hi,
I presume your Web Service needs HTTP (BASIC?) Authentication.
All this needs is setting the following 2 properties, which as can be seen, you are setting....
UTL_DBWS.set_property(l_call, 'USERNAME', '<username>');
UTL_DBWS.set_property(l_call, 'PASSWORD', '<pwd>');
This should work as long as your DBWS Callout Utility was downloaded from OTN after June 2008, and it's version is atleast 10.1.3.1.
Following is a sample code snippet that was tested successfully for this :
Declare
l_service UTL_DBWS.service;
l_call UTL_DBWS.call;
l_result sys.XMLTYPE;
l_request sys.XMLTYPE;
BEGIN
l_service := UTL_DBWS.create_service(null);
l_call := UTL_DBWS.create_call(l_service);
UTL_DBWS.set_target_endpoint_address(l_call, 'http://xxx.oracle.com:8888/basic/MyWebService1SoapHttpPort');
UTL_DBWS.set_property(l_call, 'USERNAME', 'username');
UTL_DBWS.set_property(l_call, 'PASSWORD', 'pwd');
UTL_DBWS.set_property(l_call, 'OPERATION_STYLE', 'document');
UTL_DBWS.set_property(l_call, 'SOAPACTION_USE', 'true');

Comments -
The web service operation only has input message. The input message consists of a complex type as seen in WSDL.
Questions -
1. This is my first attempt in invoking a web service from pl/sql program. Is the code in SOAP body correct as mapped to the complex type in WSDL ?
2. As seen from the dbms_out - the last message before ORA-12560 is 5.5, that means the call is erroring at following code line -
http_req:= utl_http.begin_request ------ what am I doing wrong here ?
3. The web service is SSL as seen from WSDLand needs a username/password for access - which is being performed by following code line -
utl_http.set_authentication(http_req, '<username for webservice>', '<password for webservice user>'); ------- is that correct ?
4. I am not using any proxy server - should I be using it ? When is it necessary to use proxy ?
Appreciate any help.
Thanx.

Oracle is hosted by HOST A - this is where the pl/sql program resides.
The Web Service being accessed by pl/sql program is hosted by HOST B and there are 4 firewalls in between.
Oracle was not even able to establish connection to web services host.
Escalated the issue with networking folks and they resolved the connectivity problem.
Hope that helps.

How to call Web Service using http?

Hello everyone,
I have created a web service in weblogic 8.1sp4. The web service is deployed and in the test page in the administration console I see that the wsdl is sth like
http://localhost:6101/SomeWebService/SomeWebService/SomeWebService?WSDL
How is it possible to call the web service operation (let's say someOperation) using http? The problem is that the client which will call the operation is not a java or .net one and is needs to do the call using a URL. I have tried sth like
http://localhost:6101/SomeWebService/SomeWebService/SomeWebService?string=somestring&operation.invoke=someOperation which is the URL used in the test page in the administration console and although it works, instead of getting the SOAP response back I get the whole html page returned by the test page.
Please help me,
Thanks,
Yiannis

Hi Shreyas,
From your post, it seems that you are using SharePoint 2013 workflow platform in SPD.
If that is the case, we can use Call HTTP web service action to get the item data, but we cannot use Call HTTP web service to create a new item in the list in another web application with these data.
As my test, we would get Unauthorized error when using Call HTTP web service action to create a new item in a list in another web application.
So I recommend to achieve this goal programmatically.

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!!!

Web Service using HTTP-XML Protocol

Can anyone provide an example of a web service in WebLogic 8.1 using the http-xml protocol (i.e., not using SOAP)? I am trying to understand how to gain access to the xml within the http post using WebLogic's web service paradigm within WebLogic Workshop.

Hi Ananth,
thank you, but this document does not help at all.
We are using Crystal Reports 2008 SP2.
We want to use the Web Service Connector.
What I need is more informationen about the Web service connect. For example - the connection in Microsoft InfoPath is much easier - there I don't have to enter a port and can choose the methods from a list.
Is it possible to use the Crystal web service connector for MS SharePoint Webservices?
Or must I use the Crystal SDK to carry out a connection?
Best regards,
Sebastian

Invoking P6 web services using PL/SQL block

Hi Team,
We have requirement like
Oracle jobs will invoke PL/SQL code to authenticate and establish a session with the P6 Web services.
Web service will export Project data from One Primavera database as an XML and copy to common location.
Then this XML project files will be imported into archive database.
Could anyone help me how I can establish sessio between Pl/SQL and P6 webservices?
Please let me know if you need any more information.
Regards,
Santosh

It will be no different than connecting to any web services through PL/SQL which is pretty hard to do and if you are asking how to do it then you have a steep learning curve ahead of you and not a great deal in the way of good examples out there.
I wouldn't even attempt the approach you suggest. Instead I would probably write a Java application to do it and use your PL/SQL to enqueue a message that routed to the Java application. Then the java application with the Web Services support and P6 client would be easier to do what you want with web services.

Oracle is hosted by HOST A - this is where the pl/sql program resides.
The Web Service being accessed by pl/sql program is hosted by HOST B and there are 4 firewalls in between.
Oracle was not even able to establish connection to web services host.
Escalated the issue with networking folks and they resolved the connectivity problem.
Hope that helps.

Visual Composer - access Web Services using http proxy

Hi,
I want to use an external web service in the Visual Composer. I set up the service in NWA -> SOA Management -> Destination Template Management.
I defined the http proxy in System Global Settings. The proxy requires authentication so I provided username and password.
When I want to access the web service in the Visual Composer the log file shows this:
com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (407) Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. ). The requested URL was:"myWSURL"
It seems that authentication is not performed although I provided the correct credentials. Using (internal) web services without the proxy works fine with the visual composer.
Any ideas? Thanks, Kevin

How to read a web page using https ?

Hi,
I'm trying to read a page under a HTTPS connection. I got a certificate from my server and I'm not behind a firewall.
I find everthing confusing here, and the Java Secure Socket Extension Reference Guide from Sun is not helping too much.
If anyone could post some simple sample code to from the absolute 0, read the full page it would be really, really appreciated. It must include all the steps (from setting the trustStore pointing to the certificate, to actually reading the page).
And yes, I know this is really dummy, but I'm new to the connection part of the Java API and time is really short to solve this.
Thanks in advance,
- Juan

Amacfal,
First of, thank you for your help. But I'm trying to read a page using a HTTPS connection, and the code below (very similar to mine) doesn't work. At some point you must state where you got the PFX file. Where and how, I don't know.
Regards,
- Juan
Here is some sample code:
private void getWebPage(String searchPageURL)
//Local Attributes
String readString;
URL url;
URLConnection urlConnection;
BufferedReader HTMLpage;
try
//Connecting to URL
url = new URL(searchPageURL); //e.g.
/e.g. searchPageURL = "http://www.yahoo.com"
urlConnection = url.openConnection();
HTMLpage = new BufferedReader(new
r(new InputStreamReader(url.openStream()));
//Looping through Web Page
while((readString = HTMLpage.readLine()) !=
)) != null)
System.out.println(readString);
catch (Exception e)
e.printStackTrace();
// NEED TO MANAGE ERRORS + LOG FILE
}You will need to import the following:import java.net.*;
import java.io.*;
