From Elixir, I am trying to call a SOAP Web Service with detergentex, which is a wrapper around the Erlang library detergent.
I can call the SOAP Web Service in the example on the detergent home page with no problems: http://www.webservicex.net/convertVolume.asmx?WSDL
Parameters:
wsdl_url = "http://www.webservicex.net/convertVolume.asmx?WSDL"
action = "ChangeVolumeUnit"
parameters = ["100","dry","centiliter"]
However when trying to call an Axis2 Java SOAP Web Service I am having some problems. Example: http://www.thomas-bayer.com/axis2/services/BLZService?wsdl
When calling "getBank" in the following way
wsdl_url = "http://www.thomas-bayer.com/axis2/services/BLZService?wsdl"
action = "getBank"
parameters = ["abc"]
wsdl = Detergentex.init_model(wsdl_url)
res = Detergentex.call(wsdl, action, parameters)
I get the following error message:
{:error, 'Struct doesn\'t match model: recordtype not expected: p:getBank'}
with the following stack trace
src/erlsom_write.erl:357: :erlsom_write.findAlternative/4
src/erlsom_write.erl:258: :erlsom_write.processSubType/5
src/erlsom_write.erl:241: :erlsom_write.processElementValues/7

src/erlsom_write.erl:45: :erlsom_write.write/2
src/detergent.erl:211: :detergent.call_attach/8
Any suggestions as to what I'm doing wrong?
According to the implementation a prefix is added on the init_model.
def init_model(wsdl_url, prefix \\ 'p') do
Detergentex.Client.init_model(wsdl_url, prefix)
end
I would suggest to add an empty prefix.

I created two grails project, one for server side cxf web service and other for cxf client for calling web service..
Everything works fine.
I can call web service from client code and get result.
Now I want to add security, then what will be the changes to server and client grails code?
I tried applying security as said by Christian Oestreich in his post.
http://www.christianoestreich.com/2012/04/grails-cxf-interceptor-injection/
(Grails Cxf Interceptor Injection 2.4.x-2.5.x)
and client code for applying security is as follows
ExampleService exampleService = new ExampleService()
def port = exampleService.exampleServicePort
Map ctx = ((BindingProvider)port).getRequestContext();
ctx.put("ws-security.username", "pankaj");
ctx.put("ws-security.password", "pankaj");
println ".......... " + port.sayHello("pankaj")
But I am getting error as follows
Error |
2014-11-06 18:33:15,411 [http-bio-8088-exec-4] ERROR errors.GrailsExceptionResolver - SoapFault occurred when processing request: [GET] /WSDLDemoClient/wsdldemo/index

Message: An error was discovered processing the <wsse:Security> header.
Line | Method
->> 75 | unmarshalFault in org.apache.cxf.binding.soap.interceptor.Soap11FaultInInterceptor
Instead of above mentioned client code, use following code to get it working.
Map<String, Object> req_ctx = ((BindingProvider)hello).getRequestContext();
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, WS_URL);
Map<String, List<String>> headers = new HashMap<String, List<String>>();
headers.put("Username", Collections.singletonList("pankaj"));
headers.put("Password", Collections.singletonList("pankaj"));
req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
SUM: I ended up having to form the XML manually. I also had to create an Operation and use its send(); method rather than just doing something like WebService.MyServiceFunction(); - not sure why that was the case.
I send off the request as follows:
var xm:XML =
<SetPropertiesForCurrentUser xmlns="http://asp.net/ApplicationServices/v200">
<values xmlns:d4p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<d4p1:KeyValueOfstringanyType>
<d4p1:Key>{obj.Key}</d4p1:Key>
<d4p1:Value xmlns:d6p1="http://www.w3.org/2001/XMLSchema" i:type="d6p1:string">{obj.Value}</d4p1:Value>
</d4p1:KeyValueOfstringanyType>
</values>
</SetPropertiesForCurrentUser>;
var profileService:WebService = new WebService();
profileService.useProxy = false;
profileService.loadWSDL(url);
var o:Operation = profileService.SetPropertiesForCurrentUser;
o.send(xm);
Here’s my scenario:
I have ASP.NET web services to handle authentication, user roles, and user profiles (default ASP.NET AuthenticationService, RoleService, and ProfileService, to be exact).
So from my Flex web app, I am able to successfully call the ASP.NET service. For example, something like this works fine:
var profileService:WebService = new WebService();
profileService.useProxy = false;
profileService.GetAllPropertiesForCurrentUser.addEventListener("result",getAllPropertiesForCurrentUser_EventHandler);
profileService.addEventListener("fault",getAllPropertiesForCurrentUserFault_EventHandler);
profileService.loadWSDL(url);
profileService.GetAllPropertiesForCurrentUser();
I run into trouble when I need to pass a Dictionary object to another function on the service (SetPropertiesForCurrentUser). The .NET service asks for this type of value:
System.Collections.Generic.IDictionary(Of String, Object)
Here are the two pertinent entries from the web.config entry from my ASP.NET service:
<properties>
<clear/>
<add name="coordinateFormat" />
</properties>
...
<profileService enabled="true"
readAccessProperties="coordinateFormat"
writeAccessProperties="coordinateFormat"/>
So after putting together a SOAP request from a Silverlight app (which works as expected) I’ve narrowed it down to a difference in the XML request sent to the SOAP handler:
From Flex:
<tns:Value>DMS</tns:Value>
From Silverlight:
<d4p1:Value xmlns:d6p1="http://www.w3.org/2001/XMLSchema" i:type="d6p1:string">DMS</d4p1:Value>
If I take the request generated by Flex, catch it with Fiddler, modify that one line to include the “type” namespace – it works.
Anyone have an idea how I can get that namespace onto my variable that is passed to the SOAP handler from Actionscript? Here is my code for sending off that SetPropertiesForCurrentUser function:
var obj:Object = {};
obj["Key"] = "coordinateFormat";
obj["Value"] = DMS;
var profileService:WebService = new WebService();
profileService.useProxy = false;
profileService.SetPropertiesForCurrentUser.addEventListener("result",setPropertiesForCurrentUser_EventHandler);
profileService.addEventListener("fault",setPropertiesForCurrentUserFault_EventHandler);
profileService.loadWSDL(url);
profileService.SetPropertiesForCurrentUser(new ArrayCollection([obj]),false);
Thanks,
Josh
The default SOAPEncoder that is used is some what limited in its capabilities (like not including the type attribute you mentioned above). Luckily, there is a way to control that by writing your own encoder.

I'm currently trying to call Amazon Product Retail Web Service in Salesforce.
As I mentioned in
Getting WSDL parse error while generating Apex code from WSDL in Salesforce
I was initially unable to generate apex stub class, but I followed the method suggested by #Ballinger and created apex class. I wrote an apex class to use that stub and to set request parameters. The class i wrote is as follows
public class AmazonProductStubNew
{
public static void getResults()
{
System.Debug(' getResults start ');
AmazonWS.AWSECommerceServicePortUS stub = new AmazonWS.AWSECommerceServicePortUS();
stub.inputHttpHeaders_x = new Map<String,String>();
stub.inputHttpHeaders_x.put('AWSAccessKeyId','MyAmazonAWSAccessKeyId');
stub.inputHttpHeaders_x.put('Timestamp','2012-11-28T12:11:30Z');
stub.inputHttpHeaders_x.put('Signature','Encrypted Secret Code');
String MarketplaceDomain = '';
String AWSAccessKeyId = 'MyAmazonAWSAccessKeyId';
String AssociateTag = '';
String XMLEscaping = '';
String Validate = '';
AmazonWS.ItemSearchRequest Shared = new AmazonWS.ItemSearchRequest();
Shared.SearchIndex = 'DVD';
AmazonWS.ItemSearchRequest[] Request = new AmazonWS.ItemSearchRequest[1];
Request[0] = new AmazonWS.ItemSearchRequest();
Request[0].Title = 'Inception';
AmazonWS.ItemSearchResponse_element response = stub.ItemSearch(MarketplaceDomain,AWSAccessKeyId,AssociateTag,XMLEscaping,Validate,Shared,Request);
AmazonWS.Items_element[] localItems = response.Items;
System.Debug(localItems[0].TotalResults);
}
}
Even though I've added HTTP headers to stub, I'm not getting it in XML Request message
XML Request is as follows
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<env:Header />
<env:Body>
<ItemSearch xmlns="http://webservices.amazon.com/AWSECommerceService/2011-08-01">
<MarketplaceDomain>
</MarketplaceDomain>
<AWSAccessKeyId>MyAWSAccessKeyId</AWSAccessKeyId>
<AssociateTag></AssociateTag>
<XMLEscaping></XMLEscaping>
<Validate></Validate>
<Shared><SearchIndex>DVD</SearchIndex></Shared>
<Request><Title>Inception</Title>
</Request></ItemSearch>
</env:Body></env:Envelope>
Since headers are not there in SOAP Request, There is a SOAP fault asking for Signature from Amazon Server.
As you can see, I'm new to Salesforce Apex. I followed the steps in
http://www.salesforce.com/us/developer/docs/apexcode/index_Left.htm#StartTopic=Content/apex_web_services_wsdl2apex.htm#http_header_support
to set the headers.
Any idea on why the header isn't getting added?
P.S I added headers manually and tried in SOAP UI, I'm getting proper response.
Thanks :)
I think you're using wrong functions :) (question is indeed confusing).
SOAP (or generally HTTP) communication consists of sending headers and actual message (payload if you like). Headers are short text thingies, message is often a giant XML.
Your code is setting HTTP headers (which are used in web communication to authenticate, provide info about your browser, preferred languages, set cookies, return status codes like 404 page not found...) Please don't be offended with the "for dummies" but I realize the wikipedia article is a bit too much, this might be simpler: http://net.tutsplus.com/tutorials/other/http-headers-for-dummies/
And what I suspect Amazon's webservice wants is just some fields inside the <env:Header>...</env:Header> tag? Just check the generated apex code for existence of subclass called "Header" (you can also search for the variable names like "Signature". This is going to be a total wild guess but I think you'll have to write something like that:
AmazonWS.AWSECommerceServicePortUS stub = new AmazonWS.AWSECommerceServicePortUS();
AmazonWS.Header h = new AmazonWS.Header();
h.AWSAccessKeyId = 'MyAmazonAWSAccessKeyId';
h.Timestamp = '2012-11-28T12:11:30Z';
h.Signature = 'Encrypted Secret Code';
stub.Header = h; // plug it into the request
// create and plug other required tags
AmazonWS.ItemSearchRequest Shared = new AmazonWS.ItemSearchRequest();
Shared.SearchIndex = 'DVD';
AmazonWS.ItemSearchRequest[] Request = new AmazonWS.ItemSearchRequest[1];
Request[0] = new AmazonWS.ItemSearchRequest();
Request[0].Title = 'Inception';
// ...
Now, to make it more confusing you might still have to use a HTTP header, there's a special one called SOAPAction. But generally speaking I believe you're after placing your data in the XML, not in http headers.
Funny enough, I've downloaded the Java example from http://aws.amazon.com/code/Product-Advertising-API/2478 and if I read it correctly they're passing the signature in the URL (endpoint), not in the XML. Probably because it's a REST GET method (if you can access that API it could save you a lot of hair pulled, SOAP is clunky).
I am currently developing a web app which should do restful service calls to existing web service api.
What I have is the base URL and the API names.
Any help on how do I start working on it?
I suppose I need to use httpbuilder for the base url I have, then followed by /api name. But how do I test it on grails if its working?
When I paste the base url on the browser it does return some xml information, so what I need is to do it on grails instead.
XML response when I paste the url through browser
<ns1:createNewUserResponse>
<userId>21</userId>
</ns1:createNewUserResponse>
So I need to be able to get this response through my web-app (grails) instead of pasting it on the browser.
EDIT*
this is a good example I found useful
#Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.0-RC2' )
import groovyx.net.http.*
import static groovyx.net.http.ContentType.*
import static groovyx.net.http.Method.*
def http = new HTTPBuilder( 'http://ajax.googleapis.com' )
// perform a GET request, expecting JSON response data
http.request( GET, JSON ) {
uri.path = '/ajax/services/search/web'
uri.query = [ v:'1.0', q: 'Calvin and Hobbes' ]
headers.'User-Agent' = 'Mozilla/5.0 Ubuntu/8.10 Firefox/3.0.4'
// response handler for a success response code:
response.success = { resp, json ->
println resp.statusLine
// parse the JSON response object:
json.responseData.results.each {
println " ${it.titleNoFormatting} : ${it.visibleUrl}"
}
}
// handler for any failure status code:
response.failure = { resp ->
println "Unexpected error: ${resp.statusLine.statusCode} : ${resp.statusLine.reasonPhrase}"
}
}
but i do not understand the query part and how do I alter it to my need?
the URL I have contains credential of username and password, the response should return a securityToken which I need to get it out from the results. Any help would be greatly appreciated!
You can start with groovy-wslite, it provides both SOAP and REST webservice clients.
To make a call to a resfull service look at Groovy HttpBuidler - http://groovy.codehaus.org/HTTP+Builder
I'm trying to do integration with Salesforce using their REST API and CF8.
I got the OAuth bit working, getting data etc but now I'm trying to update some records in Contact table.
First I tought about doing it the "proper" way as their docs say -
Update a record using HTTP PATCH.
But CFHTTP doesn't support PATCH method.
So then I tried running a SOQL query:
UPDATE Contact SET MailingStreet = 'Blah Blah' WHERE Id = '003A000000Zp4ObIAJ'
but here I'm getting
{"message":"unexpected token: UPDATE","errorCode":"MALFORMED_QUERY"}
Does anyone have an idea how to do it?
You can create your own PATCH method if your client supports it, but there is an easier way. From the Force.com REST API Developer's Guide:
If you use an HTTP library that doesn't allow overriding or setting an
arbitrary HTTP method name, you can send a POST request and provide an
override to the HTTP method via the query string parameter
_HttpMethod. In the PATCH example, you can replace the PostMethod line
with one that doesn't use override:
PostMethod m = new PostMethod(url + "?_HttpMethod=PATCH");
In CF9 CFScript, using the method that Paddyslacker already suggested for adding _HttpMethod=PATCH to the URL:
private boolean function patchObject(required string sfid, required string type, required struct obj) {
local.url = variables.salesforceInstance & '/services/data/v' & variables.apiVersion &'/sobjects/' & arguments.type & '/' & arguments.sfid &'?_HttpMethod=PATCH';
local.http = new Http(url=local.url,method='post');
//... convert obj to a json string, add to local.http ...
local.httpSendResult = local.http.send().getPrefix();
}
We have a CF9 CFC that we wrote that wraps most of the REST API that we will be open sourcing soon. I'll come back and link to it when we do.
