[resolved] How to create webservice that calling to second webservice

Anonymous — Sat, 16 Nov 2024 11:56:08 GMT

Hi, I have a problem to create my own web service. I'm trying do a simple thing on weather web service example from site: http://www.deeptraining.com/webservices/weather.asmx

I want to create and deploy webservice who will be giving me a response from another external webservice. I'm using weather WSDL and create service, next step will be to create definition of this service in job. How this definition should look ??
T_esb_provider_request (xml request) ----> ????? ( between this I need to communicate with external service that will get input and give output) -----> T_esb_provider_response ( xml response)
Can someone help me to resolve this problem ??
Many Thanks
Lukasz

Hi
In Talend, you can use a tWebservice, tWebserviceInput or tSOAP to call a Soap web service, let's assuming you want to call the weather web service for example, the job design looks like:
tESBProviderRequest--main--tFlowToIterate--tFixedFlowInput--main--tWebService--main--tXMLMap--tESBProviderResponse
on tFixedFlowInput, define the input data for used later as the request parameter on twebservice
on tXMLMap, map the response data of twebservice to a Document for tESBProviderResponse

Shong to continue a topic can you tell me how to prepare connection using Twebserviceinput for complicated wsdl schema ?? I have something like this :
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="GetItemStockPrice"
targetNamespace="http://getItemStockPrice"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"

<wsdl:types>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://getItemStockPrice">
<xsd:element name="GetItemStockPriceOperation" type="tns2:GetItemStockPrice">
</xsd:element>
<xsd:element name="GetItemStockPriceOperationResponse"
type="tns2:GetItemStockPriceResponse">
</xsd:element>
<xsd:complexType name="pGetItemStockPrice">
<xsd:sequence>
<xsd:element name="Items" type="tns2:ItemsRequest"

</xsd:element>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="GetItemStockPriceResponse">

<xsd:element name="Items" type="tns2:ItemsResponse">
</xsd:element>
<xsd:element name="OrderDetails" type="tns2 rderDetails"
maxOccurs="1" minOccurs="0"></xsd:element>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="ItemsRequest">
<xsd:sequence>
<xsd:element name="item" type="tns2:ItemRequest"

</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="ItemRequest">
<xsd:sequence>
<xsd:element name="LocalID" type="xsd:string"
maxOccurs="1" minOccurs="1">
</xsd:element>
<xsd:element name="Quantity" type="xsd:int" minOccurs="0"
maxOccurs="1" nillable="false">
</xsd:element>
<xsd:element name="BasicUnit" type="xsd:string"

</xsd:complexType>
<xsd:complexType name="Header">
<xsd:sequence>
<xsd:element name="Code" type="xsd:int"></xsd:element>
<xsd:element name="Message" type="xsd:string"></xsd:element>
</xsd:sequence>
</xsd:complexType>

As you see In request I'm asking for 4 arguments but ITEMS argument is a type="tns2:ItemsRequest" so it's class of arguments. How to call that kind of class and use parameters to propagate values??
Many thanks

Hi lukasz.noga
The basis use of twebserviceInput do not support the complex type as input parameter such as an instance of a class in your case, you need to use the WSDL2Java feature in the advanecd setting panel of twebserviceInput. You can refer to a demo case in this topic:
