May I know where to download sample WSDL file? From what i know, there is a UDDI publishes over the internet which searchable by any users.
Please help. Thanks.
i can provide you upto 5 working wsdls built in .net and magento.
This is the site where you can analyze and test the wsdls.wsdl-analyzer-Link
here are the links where you can view or download the wsdls
sample
Most services publish the wsdl at the same location as the service by adding ?wsdl to the URL. You can also get xsd with the ?xsd querying
For an example, any random WSDL will not do. You would want to have one which uses the most important features, which works out of the box with most software stacks.
I've written an example WDSL as part of a test library which should fulfill most the above criteria:
Standard compatibility form (can't remember the exact name) for cross-platform tooling support. Notably, one Element for each request/response type.
Request headers
SOAP Faults
XSD in its own file
not covered is
Response header (rare)
MTOM

Is it possible to use WSDL in rest assured, I'm looking for open source API automation testing tool. My services are in WSDL, I can use SOAPUI which will extract wsdl into separate end points. but Is there any way can we extract end in WSDL manually or else how I can use this with Karate or Rest Assured.
As the author of Karate, let me give you my point of view.
You don't need to worry about WSDL. All you need is a sample SOAP envelope as XML (plain-text) and you will be easily able to derive all your tests, complex scenarios and edge cases with that. This is what many teams are doing today, and you can refer this detailed set of examples to get a sense of the possibilities: xml.feature
Even if you have some complexities like encryption and signed-headers etc, you can easily plug them into your tests using Java-interop, look at this example in the documentation: https://github.com/intuit/karate#http-basic-authentication-example
I know that REST doesn't have WSDL document as SOAP has (some has WADL but not all, and it is not that common)
Is there a tool that take REST documentation (REST uri maybe) and generate describing document for that web service?
The tool swagger https://editor.swagger.io/ is able to do it only if added annotation to the source code of the web service not to any REST web service.
In short there is no official/REST approved way of doing what you are looking for.
WADL, Swagger and RAML are all "proposed" ways of achieving WSDL like functionality in REST, however they are proposed and not wildly supported by the development community.
If you were to start a new project these would make sense but if you want to run it on top of a existing project and generate some documentation you are pretty much out of luck.
I have a SOAP based WebServices that I should consume. The WSDL file for this service contains 50 different operations and is 1000 lines in content. Out of these 50 different operations, I only use a handful of them. So here are my questions:
Can I trim this WSDL down to the set of services that I need? I can then keep a local copy of this WSDL and do the code generation when building my project.
Are there any potential dis-advatages of using this approach to trim the WSDL on the client?
Is there any good Scala based libraries that I could use?
Can I trim this WSDL down to the set of services that I need?
Yes. I've done exactly this before
Are there any potential dis-advatages of using this approach to trim
the WSDL on the client?
Depends. If you're building a client library for use by other code, you've just limited what they can do. If it's all your code, it makes it more of a pain if you find you need to add one to that handful of methods you need.
If the WSDL gets updated and re-released, you have to do your edits again.
And any change you made to the WSDL always introduces the chance of an error
Is there any good Scala based libraries that I could use?
Asking for recommendations for libraries is off topic. However, scalaxb maybe?
I am trying to create a RESTful web service that accepts JSON arguments and gives out a JSON response.
What I want is to accept HTTP requests made to my URL endpoint.
Something like,
POST /the/endpoint HTTP/1.1
Host: mywebsite.com
{"name":"yourname", "department":"your_department"}
Do a DB read at the backend and give relevant parameters like, say Manager name, salary etc as a JSON object, as the response.
What's the best way to go about it? I was thinking of using Java servlets for this? Is there a better way?
PS - I am just getting started so detailed answers or links to tutorials as to how to implement it would be much appreciated.
Thanks.
Yes you can easily do this with Servlets and some Json Libs for Marshalling /unmarshalling the Json Object to Java Object.
You can make use of Json libs like
Jackson ,
Gson etc
But you must know that REST application doesnt end with just handling the request and response , but it needs to take care of other non-functional requirements like
Authentication
Authorization
Security etc
Building this from a scratch from a Servlet is overkill and waste of time when there are ready made frameworks that these things for you
My favorite is Spring MVC 3.0
Check their project site for more details
Just to show you how easy to set up one in Spring MVC , check this below tutorial

Pls rate the post if it helps , Cheers.
If you want to go with Java, I suggest that you take a look at JAX-RS... And since REST is a complex topic, here is a url with tons of informations on it. http://code.google.com/p/implementing-rest/
As a complete beginner, I believe the best way to implement a (nearly) RESTful API without having to read a lot is simply to implement the API just using HTML pages and HTML forms with the back-end processing to handle them.
The rules are:
Use <a> tags to provide links to related resources. (navigation)
Use <form> tags to initiate any kind of processing operation on the server. (actions)
You can then make it properly RESTful by using progressive enhancement to add Javascript AJAX requests that perform PUT, PATCH, and DELETE instead of using POST for those three (of course, keeping POST for creating resources where the client doesn't know the resultant URI).
You can then click around and test the API in a web browser! Tools like Selenium can automate this.
If you need to provide JSON, this can be added after the API has been designed and tested, although libraries exist to process HTML or XHTML responses too, so JSON isn't necessarily required for machine readability.
if you are using php with symfony try:https://github.com/FriendsOfSymfony/FOSRestBundle this lets you create a real REST full servicer very quick.
Vogella made my day very easy when i started Web services with an super example here with eclipse screen shots ..Have a look here.
I have been reading about REST and SOAP, and understand why implementing REST can be beneficial over using a SOAP protocol. However, I still don't understand why there isn't the "WSDL" equivalent in the REST world. I have seen posts saying there is "no need" for the WSDL or that it would be redundant In the REST world, but I don't understand why. Isn't it always useful to programmatically bind to a definition and create proxy classes instead of manually coding? I don't mean to get into a philosophical debate, just looking for the reason there is no WSDL in REST, or why it is not needed. Thanks.
The Web Application Description Language (WADL) is basically the equivalent to WSDL for RESTful services but there's been an ongoing controversy whether something like this is needed at all.
Joe Gregorio has written a nice article about that topic which is worth a read.
WSDL describes service endpoints. REST clients should not be coupled to server endpoints (i.e. should not be aware of in URLs in advance). REST clients are coupled on the media-types that are transfered between the client and server.
It may make sense to auto generate classes on the client to wrap around the returned media-types. However, as soon as you start to create proxy classes around the service interactions you start to obscure the HTTP interactions and risk degenerating back towards a RPC model.
RSDL aims to turn rest like a hypermedia, in other words, it has more information than a service descriptor like WSDL or WADL. For example, it has the information about navigation, like hypertext and hyperlinks.
For example, given a current resource, you have a set os links to another resources related.
However, i didn't find Rest Clients that supports this format or Rest Server Solutions with a feature to auto generate it.
I think there is a long way for a conclusion about it. See the HTML long story and W3C vs Browsers lol.
For more details about Rest like Hypermedia look it: http://en.wikipedia.org/wiki/HATEOAS
Note : Roy Fielding has been criticizing these tendencies in Rest Apis without the hypermidia approach: http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven
My Conclusion : Now a Days, WADL is more common that Rest and Integration Frameworks like Camel CXF already supports WADL ( generate and consume ), because it is similar to WSDL, therefore most easy to understand in this migration process ( SOAP to REST ).
Let's see the next chapters ;)
Isn't it always useful to programmatically bind to a definition and
create proxy classes instead of manually coding?
Agree wholeheartedly, this is why I use Swagger.io
Swagger is a powerful open source framework backed by a large
ecosystem of tools that helps you design, build, document, and consume
your RESTful APIs.
So basically I use Swagger to describe my models, endpoints, etc, and then I use other tools like swagger-codegen to generate the proxy classes instead of manually coding it.

There is an RSDL (restful service description language) which is equivalent to WSDL. The URL below describes its practice http://en.wikipedia.org/wiki/HATEOAS and http://en.wikipedia.org/wiki/RSDL.
The problem is that we have lots of tool to generate code from wsdl to java, or reverse.
But I didn't find any tool to generate code from RSDL.
WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate
However, REST uses the network protocol by using HTTP verbs and the URI to represent an objects state.
WSDLs tell you at this place, if you send this message, you'll perform this action and get this format back as a result.
In REST, if I wanted to create a new profile I would use the verb POST with a JSON body or http server variables describing my profile to the URL /profile
POST should return a server-side generated ID, using the status code 201 CREATED and the header Location: *new_profile_id* (for example 12345)
I can then perform updates changing the state of /profile/12345 using the HTTP verb POST, say to change my email addresss or phone number. Obviously changing the state of the remote object.
GET would return the current status of the /profile/12345
PUT is usually used for client-side generated ID
DELETE, obvious
HEAD, gets the status without returning the body.
With REST it should be self-documenting through a well designed API and thus easier to use.
This is a great article on REST. It really help me understand it too.
WSDL 2.0 specification has added support for REST web services too. Best of both worlds scenario. Problem is WSDL 2.0 is not widely supported by most tools out there yet. WSDL 2.0 is W3C recommended, WSDL1.1 is not W3C recommended but widely supported by tools and developers.
Ref:
http://www.ibm.com/developerworks/library/ws-restwsdl/
The Web Application Description Language (WADL) is an XML vocabulary used to describe RESTful web services.
As with WSDL, a generic client can load a WADL file and be immediately equipped to access the full functionality of the corresponding web service.
Since RESTful services have simpler interfaces, WADL is not nearly as necessary to these services as WSDL is to RPC-style SOAP services.
