I have created on flow in MuleESB which is calling a web-service without any parameter just sending it username, password and token in a property and it is working fine.
But the second API I want to post some parameters while calling soap request but I don't know how to use it I tried to pass through set payload but no response.
use Webservice consumer and add a transform message component beofre it. by doing so you can automatically map all the parameters which are required by the SOAP webservice, as datasence will automaticall download the meta deta of the service using the WSDL file.
Make sure you select application/xml as content type in Postman or SOAP UI and select POST.
Use CXF and select Operation as Proxy Service ,Provide details. Selct and provode (WSDL,MTOM enabled,SOAP Headers ,SOAP 1.2)
Make sure you posting XML request "POST" method in allowed methods.
Use 2 transformers. XML to DOM and DOM to XML.
Log the request using
#[message.payloadAs(java.lang.String)]
Use a groovy script transformer to retreive the entire payload.
def userSoapRequest = new XmlSlurper().parseText(payload);
def userId = userSoapRequest.userId.text();
message.setInvocationProperty('userId', userId);
6.Retrieve userId like above and similarly for all the elements.
7.Process them as you want.
Hope this helps

I am using webclient to call 3 different external APIs in parallel using Mono zip. Now, if any error occurs in any of the API call, I have handled it through a common exception handler using ExchangeFilterFunction. Now, I want to know which particular request fails(out of 3 external API calls) ? Is there any way I can identify that? I also want to append the 'input request body' with the exception response I got from the API call. Can I fetch the request body for which the API Fails (in filter itself)?
In the ExchangeFilterFunction you have access to the request. You could "decorate" your request with some identifier and then use it to resolve the client.
You could add some request header to identify the client.
To keep it internal, you could use request attributes of the WebClient and then read it from the request object
webClient.get()
.uri("...")
.attributes((attributes) -> attributes.put("internal_client_id", clientId))
How to identify operation from xml content posted to WCF Service Url?
Suppose WCF Service Url is http://single.mat.nn.com and client dont want to include operation name in Url.
Problem is to identify operation on the basis of xml content posted .
I am not able to find any solution for this problem. Is it feasible to do configuration in WCF Service that can identify operation method on the basis of xml content posted to WCF Service URL.
One of the scenarios possible in Extending Dispatchers is:
Custom Operation Dispatching. Users can implement dispatching on something other than action – for example, on the body element, or on a custom message property. This can be done using the IDispatchOperationSelector interface.
Implmenting IDispatchOperationSelector will give you access to the incoming message to parse and decide which method you want to forward the request to.
The SOAP web service based on the corresponding method of the SOAPAction field request in the HTTP request. See the screenshot below.
The SOAPAction field and the method section in the request body can view the operation name of the specific request. If you want to recognize this value, we can intercept the SOAP message through the following two interfaces and get the value of the field.
https://learn.microsoft.com/en-us/dotnet/framework/wcf/extending/how-to-inspect-or-modify-messages-on-the-client
https://learn.microsoft.com/en-us/dotnet/api/system.servicemodel.dispatcher.idispatchmessageinspector?view=netframework-4.8
these two interfaces could capture the SOAP message during the communication. We could retrieve the field value and modify it.
Feel free to let me know if there is anything I can help with.
I have created an API in WSO2 EI.
API is expecting the requests to be send as JSON.
If it is a malformed JSON which is sent, then I should be able to receive it and make appropriate changes to make it a proper JSON.
Any help is much appreciated.
As we are using json-eval($.) to get the message to property, it is not working for me. What else i could try instead of json-eval to get the message as string.
WSO2 EI has the property force.json.message.validation, which can be used to validate incoming JSON payload. Please refer doc to configure this property in 'passthru-http.properties' file.
Once the property is configured, if there is a malformed JSON payload in the request, the mediation flow will be directed to the fault/error sequence. So, you can define the mediation logic to make appropriate changes to the malformed content within the fault sequence of your API.
In our project we expose a number of web-services that were generated from a wsdl. After generating them, I can see that the requests and responses are mapped to POJOs and when I am making the response, I just set a new POJO. This works really nice. However, I have a problem with the request. When we receive the request I expected that the payload will be a POJO mapping the parameters from the request. The payload becomes actually an array of objects. I can access the values but this is not very comfortable. You can take a look at the picture.
I can see that the under "Variables" in the method it is correctly matched to the POJO we would like to have. Is there some setting that I am missing somewhere so that we can get the payload to be mapped to correct POJO type?
Re-run the WSDL to Java codegen but this time with wrapper style disabled, see: https://cxf.apache.org/docs/wsdl-to-java.html#WSDLtoJava-wrapperstyle
I have a REST client that is preparing payload in JSON format and invoking a REST service. My job is to create the REST service in Mule. I need some information on how I can map the incoming Payload to a java object so that I can invoke the REST service component class and get the values passed in the JSON object. Does the payload after HTTP inbound endpoint already contain the JSON values sent by the client? In which case a simple JSON to Object mapper would map it as Hashmap?
You will most likely need to create a custom transformer for this use case if you have a special use case.
See: http://www.mulesoft.org/documentation/display/current/Creating+Custom+Transformer+Class
If you get sent JSON you can convert it into a custom class like this:
<json:json-to-object-transformer name="jsonToFruitCollection" returnClass="
org.mule.module.json.transformers.FruitCollection"/>
Alternatively You can also use ObjectMapper and can probably use a bean to map your JSON directly to your Java object in your Java class.
You can also use <json:json-to-object-transformer/> directly after your Http inbound endpoint, parse and get each element value in your Mule flow and store in variables. Then these variables can be passed into your Java class where you can map these to your Java object easily.
Both the approach will work fine
