I'm very new to webservices. I'm trying to figure out how I can formulate a request message (and determine what the response message) would be based on the wsdl description that I have.
This is from a third party web service. The WSDL description that I have access to gives me a bunch of information like <types> <message> <operation> etc.
But in the examples that I've seen online, it's showing the request mesage within the "soap:envelope" tag.
What am I missing?
Eventually I'd like to be able to call this webservice using JQuery. But I can't even figure out how to formulate the request message let alone make an ajax call to it.
any help would be appreciated.
For these types of situations I would download soapUI, point it to your WSDL and use it to generate a few sample requests to get familiar with the endpoints, messages and the data model (XSD) for the service.
Armed with soapUI's sample requests it should be fairly easy to move this to jQuery's SOAP client (assuming of cause that the service is not humongous and requires you to transfer a big object graph as XML - in these cases you might want to check if your service vendor has a REST API as these are generally very easy to work with from jQuery).

I have a SOAP endpoint which processes XML requests by identifying the unmarshalled object and then using appropriate handlers. Now, I am trying to make a new endpoint and handler method which would handle the same request differently. From what I understand, Spring-Webservices (or SOAP for that matter) doesn't have a RESTful-kind of routing for requests.
Can I route a SOAP request through two different endpoints with a URL suffix or something in the API path (kind-of RESTful) ? The namespace, localpart, etc all being same. If not, is there a way ?
SO doesn't seem to have working answers on this topic, tried this:
How can i have two separate web services with identical name space and local name requests be routed to different end points?
Multiple SOAP endpoints with one namespace & localpart
Any approach/ideas are appreciated.
As far as I understood, you need to execute different business logic methods depending on the flag value. Well, the most straightforward approach is to use an if statement directly inside the endpoint. If you want to call different API (controllers) methods, you can take a look at Spring Functional Endpoints. Though I'm not sure they are integrated with SOAP
The mentioned approaches in the question didn't work for me, so I used a mixed approach - made a RESTful api for the new endpoint with a different suffix in the url. I read the payload as a string and used marshallers to validate.
I'm using GraphQL (Spring Boot, Kotlin), and I have a specific issue with headers.
We need the client to send three pieces of information that we combine to retrieve internal sensitive data. That data is then used inside resolver codes.
Getting the headers from rest is as easy as #RequestHeader, but in GraphQL it has proved quite challenging. Is there a way I can save the headers to check for the three pieces of information I need?
I looked closely at spring security, but I can't figure out how to get a custom method to work in my method chain, much less save the headers in a way that I can access them from the domain layer.
I could always simply request the auth as a GraphQL type, but that puts a fairly high burden on the client and complicates the schema.
Any and all feedback is welcome.
GraphQL has a FetchDataEnvironment. You can use it by passing FetchDataEnvironment as the last variable in any resolver/query. Then, just call
environment.getContext<GraphQLEnvironentClass>().getHttpServletRequest.headers()
To anyone in the future - I'm sorry this code isn't exact, but your strong typing in your IDE will show you what I mean.
I have a general REST API (developed using Spring MVC) that takes a list of API requests as its request body.
Each API request in the list has its own URL and request body.
In the implementation of this general REST API, I need to call the corresponding Spring controller method (in the same app) for each of these individual API requests (with their appropriate URL and request body).
(I will then merge all those individual API responses and return it in one big response from the general REST API).
I've been searching around, but I'm unclear how to programmatically call Spring to execute each individual API request. I would ideally like to get back the ResponseEntity from each call instead of the actual JSON response.
(More information:
On the same app server as the general API, I need to translate the URL and JSON request body for each individual API into the arguments to the controller method. I also need to take the URL and have Spring determine which controller method to invoke itself.)
Any help would be greatly appreciated.
Thanks,
Matt
Answer depend on whether the individual URLs that you are planning to invoke is with in the same server (Accessible without using network call) or not
If it is with in the same app server, spawn multiple threads and invoke the individual methods and join the response together and send it back
If it is not within the same app server, there are many Async Restclients are there besides spring's own webclient/restTemplate etc
I create a new Split-Join (in the OSB workshop application). Then
I use an action "Invoke Service" to call a not secured business service. So far no problem. When I assign a security policy to my business service, the OSB does not accept. Here is the error message in the OSB workshop:
[Parallel, Scope, Invoke Service]
The WSDL Binding for BusinessService "OSB/1_0/BusinessServices/TestBS" is not supported: The service feature "WS-Security" is not supported.
How can I call a secured business service in a splitJoin?
Thanks
I'll put a little more expanded version of the correct answer of user2364825.
Split-Join is actually a "window" into an older product (that's why it looks and behave differently from OSB). That product has some limitation, including inability to work with WS_POLICY.
There are two commonly used workarounds for that.
Approach #1. Make a version of the same WSDL stripped of WS_POLICY and use it in the Split-Join. From the Split-Join, call the intermediate proxy with that stripped WSDL which in turn calls a business service with the original WSDL.
BizService(Stripped WSDL)->Split-Join->Proxy2(Stripped WSDL)->BizService(Real WSDL)
That approach only works if the WS_POLICY headers are created by OSB code.
If the message going via Split-Join already has some SOAP Headers (including Policies), those are going to be lost, and the approach #1 is not working.
Approach #2. Make a custom WSDL which wraps the original message with all its SOAP Headers and whatnot. Use that WSDL for Split-Join, pass the wrapped message to an unwrapping proxy, and then call the real proxy/biz.
BizService(Wrapper WSDL)->Split-Join->Proxy2(Wrapper WSDL)->BizService(Real WSDL)
The second approach is more complex, but also more powerful. For instance, it easily can be extended to support user headers (Split-Join doesn't support them too), passing debug information and pretty much anything else.
This approach is implemented in my GenericParallel service which does all above and some more.
I also have a blog post outlining passing the SOAP Headers via Split-Join in a bit more details. (The WS_Policy is just a SOAP Header after all).
YOu can never a call a WSDL based proxy/Business Service that has WS_POLICY defined in the WSDL. You need to have a intermediate business/proxy to pass the message to the WS-policy containg WSDL service.
what is different between ajax and webservices. Anybody provide with some examples?
It's nonsensical to compare these things.
"Ajax" is a process that occurs in the browser. It is the act of calling some local server-side page, without refreshing the "main" viewing area, and then doing various things with that result (grabbing the data, making changes, changing the existing DOM (adding elements), whatever).
Webservices are a Serverside-thing that allows you to call methods, in your code, but have that call actually go to a remote machine. The call to the Webservice is generally also made server-side.
The term "Ajax" is generally used :
When the request is sent by a browser (client-side) to a server
When the transfered data is XML or JSON or HTML.
The word "webservice" is generally used :
When the request is sent by a server to another server, without a browser being involved
When the transfered data is SOAP -- at least when it's a SOAP webservice ^^ (Opposed to REST, for instance, which generally doesn't imply SOAP)
But I'd say that Ajax is basically some specific kind of webservice.
i think ajax and web services are kind of similar, here is why i think so.
as i understood it, in your app sometimes you will have to implement an "API" which has several useful functions. and it is those functions which are called "web services". these 'functions' acts in response to the http requests and "does" something with the data provided.
in ajax siimilar kind of work happens as well,just through javascript thats it.
so, to sum it all up, an API has 'web services' within it, and ajax behaves like 'web services'. in this manner, yes i think it is correct to call ajax and web services similar.
