How to set a value to a javax.xml.ws.Holder?
提问by Erik Clairiot
we are currently having problems with a JAX-WS implementation, particulary in getting a value returned by the service, which in our case is always null, although we give it a value.
我们目前在 JAX-WS 实现方面遇到了问题，特别是在获取服务返回的值方面，在我们的例子中它始终为 null，尽管我们给了它一个值。
Some code before more explanations of our problem :
在对我们的问题进行更多解释之前的一些代码：
Here is the signature of our operation :
这是我们操作的签名：
@WebMethod(action = "urn:genererEdition")
public void genererEdition(
@WebParam(name = "requeteEdition", targetNamespace = "http://creditcgi.com/serviceeditique", partName = "requete")
RequeteEdition requete,
@WebParam(name = "reponseEdition", targetNamespace = "http://creditcgi.com/serviceeditique", mode = WebParam.Mode.OUT, partName = "reponse")
Holder<ReponseEdition> reponse,
@WebParam(name = "documentProduit", targetNamespace = "", mode = WebParam.Mode.OUT, partName = "documentProduit")
Holder<byte[]> documentProduit);
Here is our web service test case :
这是我们的 Web 服务测试用例：
@Test
public void testCallGenererEdition() {
RequeteEdition requete = new RequeteEdition();
Holder<ReponseEdition> reponseHolder = new Holder<ReponseEdition>(new ReponseEdition());
Holder<byte[]> documentHolder = new Holder<byte[]>(new byte[512]);
editique.genererEdition(requete, reponseHolder, documentHolder);
Assert.assertNotNull(reponseHolder.value);
Assert.assertNotNull(reponseHolder.value.getCodeRetour());
}
And finally, our WS implementation :
最后，我们的 WS 实现：
@Override
public void genererEdition(RequeteEdition requete,
Holder<ReponseEdition> reponse, Holder<byte[]> documentProduit) {
// if we do no instanciate ReponseEdition, we got a Null Pointer Exception
reponse.value = new ReponseEdition();
reponse.value.setCodeRetour("OK");
}
As you can see with the test, we are always getting null. What do we do wrong for always having a null object returned in the reponse Holder ?
正如你在测试中看到的，我们总是得到 null。总是在响应 Holder 中返回空对象，我们做错了什么？
Thank you in advance.
先感谢您。

It will solve your problem of getting NULL values in response.
它将解决您在响应中获取 NULL 值的问题。
....genererEdition(....){
ReponseEdition re = new ReponseEdition();
reponse.value = re;
}
....genererEdition(....){
ReponseEdition re = new ReponseEdition();
reponse.value = re;
}
