JAXB unmarshalling exception: unexpected element WebServiceTemplate spring boot

Question

i'm working in a spring boot project where i'm trying to make a SOAP request using WebServiceTemplate but i got the following error :

javax.xml.bind.UnmarshalException: unexpected element (URI : "http://schemas.xmlsoap.org/soap/envelope/", local : "Fault"). the expected elements are <{urn:xtk:session}Logon>,<{urn:xtk:session}LogonResponse>

im trying to find a solution since 3 days but i didn't find it yet. this is my code :

WSDL file :

Generated Classes :

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "sessiontoken",
    "strLogin",
    "strPassword",
    "elemParameters"
})
@XmlRootElement(name = "Logon")
public class Logon { 
...

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "pstrSessionToken",
    "pSessionInfo",
    "pstrSecurityToken"
})
@XmlRootElement(name = "LogonResponse")
public class LogonResponse {
// attributes...

package-info class :

@javax.xml.bind.annotation.XmlSchema(namespace = "urn:xtk:session", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.api.soap;

my config Class :

@Configuration
public class SoapConfig {
    
    @Bean
    public Jaxb2Marshaller marshaller() {
        
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setPackagesToScan(new String[]{
                 "com.api.soap"
        });
        
        return marshaller;  
    }
}

and finally this is my methode to call my the soap WS :

Logon logonRequest = new Logon() ;

logonRequest.setSessiontoken("");
logonRequest.setStrLogin("myusername"); //
logonRequest.setStrPassword("mypassword");  //

webServiceTemplate = new WebServiceTemplate(marshaller);
LogonResponse logonResponse = (LogonResponse) webServiceTemplate.marshalSendAndReceive("http://ws-soap-serv.com",logonRequest);
    

do you have any idea why i'm getting this error please :

javax.xml.bind.UnmarshalException: unexpected element (URI : "http://schemas.xmlsoap.org/soap/envelope/", local : "Fault"). the expected elements are <{urn:xtk:session}Logon>,<{urn:xtk:session}LogonResponse>

Best Regards.

On your WebServiceTempmate use

template.setCheckConnectionForFault(false);
