cvc-elt.1: Cannot find the declaration of element

Question

I am new to xsd and soap. I created an xsd and want to configure it for spring ws .Currently I am getting an error. I followed this . I think I am making some small mistake regarding xsd.

(1) UserDetails.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
        xmlns="http://reqres.data.ws.akash.com/userdetails" 
        xmlns:tns="http://reqres.data.ws.akash.com/userdetails" 
        targetNamespace="http://reqres.data.ws.akash.com/userdetails"
        elementFormDefault="qualified">

    <xsd:element name="UserDetailsRequest">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="UserData" type="UserData"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>

    <xsd:complexType name="UserData">
        <xsd:sequence>
            <xsd:element name="userId" type="xsd:string"/>
        </xsd:sequence>
    </xsd:complexType>

    <xsd:element name="UserDetailsResponse">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element  name="AccountDetails" type="tns:UserDetails"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>

    <xsd:complexType name="UserDetails">
        <xsd:sequence>
            <xsd:element name="userId" type="xsd:string"/>
            <xsd:element name="username" type="xsd:string"/>
            <xsd:element name="age" type="xsd:int"/>
            <xsd:element name="emailId" type="xsd:string"/>
            <xsd:element name="userSalary" type="xsd:double"/>
            <xsd:element name="userGender" type="tns:UserGender"/>
        </xsd:sequence>
    </xsd:complexType>

    <xsd:simpleType name="UserGender">
        <xsd:restriction base="xsd:string">
            <xsd:enumeration value="Male"/>
            <xsd:enumeration value="Female"/>
        </xsd:restriction>
    </xsd:simpleType>

</xsd:schema>

(2) I created stub class from this xsd by using JAXB (generate classes from schema)

(3) wsdl file created from xsd

(4) Endpoint class for wsdl

package com.akash.ws.endpoint;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
import org.springframework.ws.server.endpoint.annotation.RequestPayload;
import org.springframework.ws.server.endpoint.annotation.ResponsePayload;

@Endpoint
public class UserDetailEndpoint {

    private static final String NAMESPACE="http://reqres.data.ws.akash.com/userdetails";

    @Autowired
    @Qualifier("userService")
    private UserDetailsService userDetailsService;

    @PayloadRoot(localPart="UserDetailsRequest",namespace=NAMESPACE)
    public @ResponsePayload UserDetailsResponse getUserDetail(@RequestPayload UserDetailsRequest userDetail) {

        UserDetailsResponse udr=new UserDetailsResponse();
        UserDetails ud=new UserDetails();
        ud.setAge(35);
        ud.setEmailId("obama@gmail.com");
        ud.setUserGender(UserGender.MALE);
        ud.setUserId("1");

(5) Soap request from SOAP UI

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:user="http://reqres.data.ws.akash.com/userdetails">
   <soapenv:Header/>
   <soapenv:Body>
      <user:UserDetailsRequest>
         <user:UserData>
            <user:userId>1</user:userId>
         </user:UserData>
      </user:UserDetailsRequest>

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Client</faultcode>
         <faultstring xml:lang="en">Validation error</faultstring>
         <detail>
            <spring-ws:ValidationError xmlns:spring-ws="http://springframework.org/spring-ws">cvc-elt.1: Cannot find the declaration of element 'user:UserDetailsRequest'.</spring-ws:ValidationError>
         </detail>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

please help.

Answer 1

I got the solution for the problem.My xsd file was valid but I had configured a validator interceptor in my xml file which was validating my request and response object.

<sws:interceptors>
        <bean class="org.springframework.ws.server.endpoint.interceptor.PayloadLoggingInterceptor" />

        <bean id="validatingInterceptor"
                class="com.akash.ws.interceptor.PayloadValidatingInterceptorWithSourceFix">
            <property name="schema" value="schema/UserDetails.xsd"/>
            <property name="validateRequest" value="true"/>
            <property name="validateResponse" value="true"/>
        </bean>
    </sws:interceptors>

currently I do not know how to validate my xsd request and response object but WS communication I disabled this feature by request and response object as false.

<property name="validateRequest" value="false"/>
<property name="validateResponse" value="false"/>
