IllegalAnnotationException：两个类具有相同的 XML 类型名称

Question

I am developing web service under JBoss 5 and Java 1.6. What could possibly cause this exception? Below is my simplified web service code.

@Stateless
@WebService()
public class AccountWS {

@WebMethod()
public CreateAccountResponse createAccount(@WebParam(name = "request") CreateAccountRequest request) {
    return null;
}

And below is the full stack trace.

Answer 1

I found the cause of my problem.

This problem occurs because JAX-WS generates a class for each method and the class name is constructed by concatenating methodName + "Response" . In my case, the newly generated class by JAX-WS will have the same name as my response object .

Example:

@Stateless
@WebService()
public class AccountWS {

    @WebMethod()
    public CreateAccountResponse createAccount(@WebParam(name = "request") CreateAccountRequest request) {
        return null;
    }
}

JAX-WS will generate a new class CreateAccountResponse for Web Method createAccount which has the same name as the response object.

Solution:

Make sure that the name of the response object and method doesn't match . The same thing applies to the method parameter as well.

Answer 2

You have two XML schema elements with the same name ( createAccountResponse ) and the same namespace ( http://kona.webservice.sif.unidata.com/ ) corresponding to the Java types com.unidata.sif.kona.account.message.CreateAccountResponse and com.unidata.sif.webservice.kona.jaxws.CreateAccountResponse . As the second one is "automagicaly" generated by the WebMethod annotation, it will be easier changing the XMLType anotation for the message element.

To solve it, you should change the name for one of them, or define two separated namespaces (one for the message elements, and another one for the WS request and response components). I recommend the last approach (two separated namespaces).

IE:

1. Changing the name of the message element com.unidata.sif.kona.account.message.CreateAccountResponse .

@XMLType(name="CreateAccountResponseMsg", namespace="http://kona.webservice.sif.unidata.com")

2. Changing the namespace at message elements (package com.unidata.sif.kona.account.message )

@XMLType(name="CreateAccountResponse", namespace="http://kona.webservice.sif.unidata.com/message")

Answer 3

I got the same error but I couldn't ajust the classes with @XmlType annotation (coming from library) So another solution is to provide a com.unidata.sif.kona.account.message/package-info.java with following code inside

@javax.xml.bind.annotation.XmlSchema(namespace = "http://kona.webservice.sif.unidata.com/")
package com.sopra.banking.processengine.servicecontract.v1_1.dto;

Answer 4

Another solution is to use @WebMethod(operationName="differentFromMethodName") . This will even change the interface method name on the client. JAX-WS still generates the classes for both wsgen and wsimport using the SEI's method name; but now the message element classes are different than the JAX_WS internally generated ones.

I did not want to touch the wsgen generated classes (message element classes).
