Working on a docuSign integration with Coldfusion and need assistance in making the SOAP request using WS security.
Your question is a little short on detail, but I presume you mean the Web Services SOAP security extension.
We had to do this a few years back when communicating with a .NET web service. The basic idea is that you provide a set of extra SOAP headers that contains security info such as:
Timestamp
Username
Password
Etc
To do this you need to create a new XML document as per the standard defined here. Next you will need to write code to create the SOAP headers. This means:
Create your remote web service object, e.g.
var objWebSvc = createObject("webservice", "http://remoteURL?WSDL");
Creating an XML document to represent the new headers
Populating it with the required info (such as username and timestamp etc.)
Adding the XML document to the web service object, using addSOAPRequestHeader()
Call your remote web service
Then of course if and when they call your web service you'll need to parse out those headers from their SOAP request and validate them. That can be done by grabbing the XML using getSOAPRequestHeader() and parsing out the info.
I found this to be an error prone task and (basically) a royal pain. The web service we integrated with eventually dropped the requirement, apparently becuase the any web services trying to connect that were not native .NET were having a hard time implementing the specification.
Good luck!
I blogged this a while back. See if this helps:

Due to the fall of SOAP::WSDL which had generated me real Perl modules I have to look for something other in order to handle a SOAP service. The generated modules won't work starting from Perl v5.18.
I have the following situation with my web application.
I have a PSGI compatible, Dancer2 driven, persistent web application.
The web application handles multiple concurrent customers.
The web application is between the customer and an external SOAP service.
The SOAP service uses customer sessions via cookies which have to be integrated on the web application internally for the customer.
The web application holds an WSDL file copy of the SOAP service.
I'm looking for a module that creates an interface out of the WSDL file and handles parameter/schema validation and communication with the SOAP service. I would like to call a method (SOAP call) with parameters (SOAP call parameters) and receive a cleaned data or object structure of the response.
The problem is that the web application needs to handle multiple concurrent customer cookie sessions. So I need a module which offers the possibility to override the cookie jar for that particular request and extract the cookies after the request without causing interference with other concurrent requests.
I found XML::Compile which I can initialize as a singleton at web application start up. But with this solution I ran into problems with interfering other customer requests. So the requests are not separated. Initializing XML::Compile for every request is not the solution either because it will parse the WSDL and generate handlers over and over again for every request the customer sends to the web application.
Is there any solution/module that fits my needs or do I miss something with XML::Compile and it's possible with it?
Are you using Catalyst?
I've been happy using Catalyst::Controller::SOAP and its companion Catalyst::Model::SOAP to build SOAP/WSDL servers and consumers, being able to integrate Perl Applications even with Microsoft Document Literal-Wrapped thing.
Even if not using Catalyst you may probably learn from its code. It uses XML::Compile::WSDL11.
I am new to web services. I have a requirement in my project. They gave me a wsdl file and a web service link and document about the description of methods.
In the documentation there is method called retriveDocuments with request parameters request, loginUser, loginPassword, systemId, maxResults, searchCriteria.
They want me call webservice and get the required documents and show them in app.
My question is how do I call web service and how do I pass all these parameters and get the result?
Most likely this a SOAP service. Your programming language (such as Java) should have tools allowing you to generate a SOAP client for the service, using the WSDL. Once you have the cient code, it should be easy to pass your parameters, make the call, and get the result. There are lots of tutorials on the Web, but you can start researching from there.
I am new to Spring web services. I am going to create an xml request, and send it as a SOAP request to a web service and receive the response.I read different documents but still confused as I could not find a working sample yet.
I know that I should use WebServiceTemplate and WebServiceMessageSender, SaajSoapmessageFactory (please let me know if I am wrong) but not sure how to use them.
Do I need WSDL? if yes why?
If you have any sample code please send me to get clear on it.
Thanks
If you want to send SOAP requests, you would like to be a SOAP client. Seems like you want to use spring-ws project. Check out their great documentation on the client side. The same documentation will guide you through the process of creating a server. There are plenty of examples and ready-made configuration snippets waiting for you.
Spring-WS is built on top of XML Schema description of your message, so you will need WSDL to generate e.g. JAXB models of your requests and responses.
AFAIK, for "web services" , the WSDL file is the machine blueprint of the "ports" as they are called However! ports in WSDL "means" java language(or any other programming language used with a routine or sub or procedure or function) method and has a specific naming scheme associate the .wsdl xml file(template of the service). Each WSDL port(language method) has specifications of return value and data specifications for how to feed it arguments and their type values.
I've started learning about webservices recently. Have few question about that:
For webservice, is it always necessary that source should provide wsdl or any other way possible to consume it without needing wsdl?
Till a while ago, I was doing server side XMLhttp post in classic ASP to do modifications in external application & to push data in my application from external application. I'm confused - is that very different from webservice or can be called a sort of webservice(ofcourse without based on SOAP). Any major difference or it is just protocol difference bw webservice and server side XMLhttp post?
Web services can be made asynchronous?(Something like AJAX call through javascript)
Are there any different types of webservices ? (for e.g is there difference bw, webservice providing stock quotes and webservice provided by google)
1.For webservice, is it always necessary that source should provide wsdl or any other way possible to consume it without needing wsdl?
WSDL is a document that publishes an interface. As long as a client complies to the inteface, it is guaranteed to be able to "talk" to the web service. Having said that WSDL is a formal way for a specification when there are many stakeholders. You can proceed without one, as long as you somehow know what the web service expects. Just wrap the application data in a SOAP envelope and send it to the web service. As long as you send what the web service expects (in the SOAP envelope or the application data) and in the way they are expected e.g. transport HTTP etc. it does not matter for the WS if you have used a WSDL or not.

In very simple terms web service is XML over some application protocol (usually HTTP). Could be SOAP based or REST. To understand more on this you should read about Service Oriented Applications
3.Web services can be made asynchronous?(Something like AJAX call through javascript)
They could but it is more complicated than that.
4.Are there any different types of webservices ? (for e.g is there difference bw, webservice providing stock quotes and webservice
provided by google)
Not sure what you ask here. Each web service offers something.
I will try to be very simple here:
The W3C defines a "Web service" as "a software system designed to
support interoperable machine-to-machine interaction over a network".
That means first requisite for any software to be web-service is that it should not depend upon platform or software i.e a web service made on java stack can be consumed by client in .net stack on windows or java stack on android.
If your server side implementation XMLhttp post suffice this ,its a
web service.
Types of Web services
Actually, there is no overall and clear categorization on types of web services. But two most popular are :
SOAP based web services. :It use XML messages that follow the Simple Object Access Protocol (SOAP) standard, an XML language defining a message architecture and message formats(WSDL).
REST based web services. With evolution of WEb 2.0 emphasis has been moving away from SOAP based services towards representational state transfer (REST) based communications.[3] REST services do not require XML, SOAP, or WSDL service-API definitions.Read here to get a easy explanation of REST
Need of WSDL to consume SOAP web services?
To consume a SOAP service we only require SOAP endpoint and XML message format. WSDL is a pre-requisite for automatic client side code generation through Java and .NET SOAP frameworks.
Asynchronous web services
Making web services asynchronous is possible.But complexity depends upon frameworks used, for example AXIS2 in JAVA has easy implementation of this.
I want to send an XML file to a Web Service.
The Web Service is a java application.
I know the endpoint of the Web Service.
Typically I know I have to create the request and send it as an http/https request.
What I want to know is what would I have to make to send the request - as in what development tool could I use e.g. Visual Web Developer (preffered as I am familiar with this) or Visual Studio? And what sends the request - e.g. another Web Service, a Website etc?
Where do I even begin with this?
Any comments are much appreciated.
Where do I even begin with this?
One purpose of a Webservice is loose coupling. So it depends on what you want to do. You can write a simple program in what ever language which constructs a request and sends it. You can write a Webservice on its own which uses the other Webservice to handle it's own requests.
You can handle this in a very simple or complex way. You only need to be able to generate a request (per xml) and send it.
