Issue is solved with JAXB data binding
3 years ago
We have a cxf based jax ws code first web service deployed in Tomcat server . The return type of one of the operation in this service is List of a custom value object . We have created a proxy web service in jboss fuse and camel route with this proxy web service and real web service . Then we have created a client artifact using the proxy web service and trying to invoke the real web service through proxy web service . All the operation working fine except the one which is returning List of complex objects . In this case getting some Unmarshalling Error



javax.xml.ws.soap.SOAPFaultException: Unmarshalling Error: unexpected element (uri:"http://vo.sample.com", local:"employeeVo"). Expected elements are <{http://vo.sample.com}empName>,<{http://http://vo.sample.com}salary>



Development environment



A ) Real web service



Tomcat 7 , cxf 2.6 ,Aegis, Java 6 ,Windows

B) Jboss Fuse



Fuse IDE 6.0.0 , Maven 3.05 , Java 6 , Windows



C) Web service Client



Artifact generated using java wsimport command





Code Snippets .



1)Real Web service interface

@WebService(targetNamespace = "http://service.sample.com", portName = "EmployeeServicePort", serviceName = "EmployeeServiceService")

@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)

public interface EmployeeService {



@WebResult(name = "retrieveEmployeeDetailsResponse", targetNamespace = "http://service.sample.com")

@WebMethod(action = "retrieveEmployeeDetails", operationName = "retrieveEmployeeDetails")

EmployeeVos retrieveEmployeeDetails(@WebParam(name = "employeeVo", targetNamespace = "http://service.sample.com")

EmployeeVo employeeVo)

;

}



2) Value object - Simple



@XmlRootElement(name="employeeVo",namespace = "http://vo.sample.com")

@XmlAccessorType(XmlAccessType.FIELD)

@XmlType(name = "EmployeeVo",propOrder={

"empName",

"salary"



},namespace = "http://vo.sample.com")

public class EmployeeVo {



public EmployeeVo(){



}





@XmlElement(name="empName",nillable=false,required=true,namespace = "http://vo.sample.com")

private String empName;





@XmlElement(name="salary",nillable=false,required=true,namespace = "http://vo.sample.com")

private Double salary;



// getters & setters



}



3) Value object - Complex





@XmlRootElement(name="emplooyeVos",namespace = "http://vo.sample.com")

@XmlAccessorType(XmlAccessType.FIELD)

@XmlType(name = "EmployeeVos",propOrder={"employeeVo"},namespace = "http://vo.sample.com")

public class EmployeeVos {





@XmlElement(name = "employeeVo", namespace = "http://vo.sample.com", required = true)

private List<EmployeeVo> employeeVo;



public EmployeeVos(){}

public EmployeeVos(List<EmployeeVo> employeeVo){

this.employeeVo =employeeVo;

}



public List<EmployyeVo> getEmployeeVo() {

return employeeVo;

}

public void setEmployeeVo(

List<EmployeeVo> employeeVo) {

this.employeeVo = employeeVo;

}



4) Camel route





<route >

<from uri="cxf:http://localhost:9080/employeeProxy?serviceClass=com.sample.service.EmployeeService"/>









<to uri="cxf:http://localhost:8080/MyTest/services/employeeService?serviceClass=com.sample.service.EmployeeService"/>



</route>



5) Invoking service ( Artifact is generated from http://localhost:9080/employeeProxy?wsdl)



Getting error





javax.xml.ws.soap.SOAPFaultException: Unmarshalling Error: unexpected element (uri:"http://vo.sample.com", local:"employeeVo"). Expected elements are <{http://vo.sample.com}empName>,<{http://http://vo.sample.com}salary>

Hi All,
We have a web service with JAX-WS ,CXF and Aegis . The return type of one operation in this service is a List of custom user defined (say List<Student>) objects. ,But while calling this operation from a camel route ,getting Unmarshalling Error:

Dear All,
My web service is enabled with https. Now I am trying to generate client for this secured service using wsimport . I have generate keys for both server and client. I am not able to generate client using wsimport for htttps wsdl . Where I have to mention the client key while generating client stub?

Can you please tell the complete step for mutual authentication ?

Thank you for reply .
As per the documentation http://docs.oracle.com/cd/E17904_01/web.1111/e15184/interop.htm ,
not good to use array wrapper elements using the convention ArrayOfXXX. Then how can be send list of objects . I was thinking to use array of value object (java bean).

eg :MyVo[] myvo

Hi Surendra,
This also not working for me. Is it working for you ? . I am using bottom up approach . Any specific schema validation limitation in code- first approach ?

Thanks

I mean no change in the generated wsdl.


- <xsd:complexType name="MyVo">
- <xsd:sequence>
<xsd:element minOccurs="0" name="name" nillable="true" type="xsd:string" />

</xsd:sequence>
</xsd:complexType>


I am using jdk1.6.0_11.

Hi All,
I am developing web services using jax-ws and apache cxf with code first approach . I want to enable schema validation in my service . For this I have configured the cxf configuration file as follows

<jaxws:endpoint id="testService"
implementorClass="com.test.impl.TestServiceImpl"
implementor="#testServiceImpl"
address="/testService">
<jaxws:serviceFactory>
<ref bean="jaxws-and-aegis-service-factory"/>
</jaxws:serviceFactory>
<jaxws:properties>
<entry key="schema-validation-enabled" value="true"/>
</jaxws:properties>
</jaxws:endpoint>

Service,

@WebService
@SOAPBinding(style=SOAPBinding.Style.DOCUMENT,use=SOAPBinding.Use.LITERAL)

public interface TestService {



@WebMethod
String test(MyVo myVo) ;

}

MyVo,


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "MyVo")
public class MyVo {

@XmlElement(name = "name", required = true)
private String name;

............. // getter and setter

}

.

But after deploying the service wsdl looks like


- <xsd:complexType name="MyVo">
- <xsd:sequence>
<xsd:element minOccurs="0" name="name" nillable="true" type="xsd:string" />

</xsd:sequence>
</xsd:complexType>


As per documentation minOccurs should be 1 (because of required=true ) .

Also I am able to call service without setting name attribute in MyVo object . No error is coming from server.


Please advice .


Thanks in advance

Hi ,
I am trying to develop some web services using jax-ws and apace cxf. I need to invoke these services from different languages like JAVA/PHP/.Net etc. I am having some doubts regarding parameters inside in the operations. I tried different approaches .

1) Passing a value object in operation as a parameter
2)Using HashMap as a parameter
3)Using ArrayList as a parameter.
4)Passing required number of string arguments (in this case 7 String parameters and one byte array ) .

I have developed one Java client using wsimport command. By using this client the fourth option is working . In the second and third options the client is generating some type like String2AnyElement for HashMap and ArrayList. How I can I put values in these types of data structure ? While trying first option there was some compilation problem also.

I went through jax-ws tutorial also, there I could see some limited data types support only

Can some one suggest best approach for designing my operations . It should be access from different platforms and different client generations tools like CXF,AXIS etc.


Thanks

Hi All,
We are using JAX-WS and apache CXF for developing web service. Our application is spring based web application and deployed in tomcat server. Now we have to encrypt our web services . What are different ways to achieve this ?
