Generated WSDL2Apex Code
You can generate Apex classes from a WSDL document using the WSDL2Apex tool. The
WSDL2Apex tool is open source and available on GitHub.
You can find and contribute to the WSDL2Apex source code in the WSDL2Apex repository on GitHub.
The following example shows how an Apex class is created from a WSDL document. The Apex class is auto-generated for you when you import the WSDL.
The following code shows a sample WSDL
document.
<wsdl:definitions xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:s="http://www.w3.org/2001/XMLSchema"

xmlns:tns="http://doc.sample.com/docSample"
targetNamespace="http://doc.sample.com/docSample"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
<!-- Above, the schema targetNamespace maps to the Apex class name. -->
<!-- Below, the type definitions for the parameters are listed.
Each complexType and simpleType parameteris mapped to an Apex class inside the parent class for the WSDL. Then, each element in the complexType is mapped to a public field inside the class. -->
<wsdl:types>

<wsdl:service name="DocSample">
<wsdl:port name="DocSamplePort" binding="tns:DocSampleBinding">

</wsdl:port>
</wsdl:service>
</wsdl:definitions>From this WSDL document, the following Apex class is auto-generated. The class name docSample is the name you specify when importing the WSDL.
//Generated by wsdl2apex
public class docSample {
public class EchoStringResponse_element {
public String EchoStringResult;
private String[] EchoStringResult_type_info = new String[]{
'EchoStringResult',
'http://doc.sample.com/docSample',
null,'0','1','false'};
private String[] apex_schema_type_info = new String[]{
'http://doc.sample.com/docSample',
'true','false'};
private String[] field_order_type_info = new String[]{
'EchoStringResult'};
}
public class EchoString_element {
public String input;
private String[] input_type_info = new String[]{
'input',
'http://doc.sample.com/docSample',
null,'0','1','false'};
private String[] apex_schema_type_info = new String[]{
'http://doc.sample.com/docSample',
'true','false'};
private String[] field_order_type_info = new String[]{'input'};
}
public class DocSamplePort {
public String endpoint_x = 'http://YourServer/YourService';
public Map<String,String> inputHttpHeaders_x;
public Map<String,String> outputHttpHeaders_x;
public String clientCertName_x;
public String clientCert_x;
public String clientCertPasswd_x;
public Integer timeout_x;
private String[] ns_map_type_info = new String[]{
'http://doc.sample.com/docSample', 'docSample'};
public String EchoString(String input) {
docSample.EchoString_element request_x = new
docSample.EchoString_element();
request_x.input = input;
docSample.EchoStringResponse_element response_x;
Map<String, docSample.EchoStringResponse_element> response_map_x =
new Map<String, docSample.EchoStringResponse_element>();
response_map_x.put('response_x', response_x);
WebServiceCallout.invoke(
this,
request_x,
response_map_x,
new String[]{endpoint_x,
'urn:dotnet.callouttest.soap.sforce.com/EchoString',
'http://doc.sample.com/docSample',
'EchoString',
'http://doc.sample.com/docSample',
'EchoStringResponse',
'docSample.EchoStringResponse_element'}
);
response_x = response_map_x.get('response_x');
return response_x.EchoStringResult;
}
}
}Note the following mappings from the original WSDL document:
- The WSDL target namespace maps to the Apex class name.
- Each complex type becomes a class. Each element in the type is a public field in the class.
- The WSDL port name maps to the stub class.
- Each operation in the WSDL maps to a public method.
You can use the auto-generated docSample class to invoke external Web services. The following code calls the echoString method on the external server.
docSample.DocSamplePort stub = new docSample.DocSamplePort();
String input = 'This is the input string';
String output = stub.EchoString(input);
