Consuming .net WCF service from Java

2020-03-26 02:32发布

问题:

I new to Java, and thought it'd be a nice learning exercise to implement a client application on top of a .NET WCF service I'm already familiar with.

I ran wsimport.bat from the latest JAX-WS (https://jax-ws.java.net/) to generate the client proxies, However I'm stuck with the authentication part. The WCF service uses Application level Username/Password to authenticate. I don't know where to supply the credentials.

In C#, for this WCF Service I just need to add a service reference, and do the following:

var client = new ServiceClient();
client.ClientCredentials.UserName.UserName = "username";
client.ClientCredentials.UserName.Password = "password";
client.DoSomething();

From Fiddler, calling client.DoSomething() produces the following request:

<?xml version="1.0"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
  <s:Header>
    <o:Security xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" s:mustUnderstand="1">
      <u:Timestamp u:Id="_0">
        <u:Created>2013-05-20T01:34:28.353Z</u:Created>
        <u:Expires>2013-05-20T01:39:28.353Z</u:Expires>
      </u:Timestamp>
      <o:UsernameToken u:Id="uuid-da5b7b57-dbb4-4c54-b529-f5b41fc728b4-1">
        <o:Username>username</o:Username>
        <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">password</o:Password>
      </o:UsernameToken>
    </o:Security>
  </s:Header>
  <s:Body>
    <DoSomething xmlns="http://tempuri.org/"/>
  </s:Body>
</s:Envelope>

Here is the Java I'm currently using:

SomeService service = new SomeService();
ISomeService port = service.getBasicHttpBindingISomeService();
DoSomethingResponse response = port.getDoSomething();

This produces the following request:

<?xml version="1.0"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
  <S:Body>
    <ns6:DoSomething xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:ns6="http://tempuri.org/" xmlns:ns7="http://schemas.microsoft.com/2003/10/Serialization/"/>
  </S:Body>
</S:Envelope>

It's missing the Security node, so I'm not sure how to set that up on the Java side. What am I missing?

I'm not 100% bound to using JAX-WS, if there is a better alternative out there for my needs. However, the WCF service can not be modified to reconfigured, as it's out of my reach.

You need to create a custom CallbackHandler from your Java client. I am not an expert in Java but I know that some of my clients use Metro libraries to communicate with my WCF web services.

Try searching for creating a CallbackHandler with/without Metro library.

You can download Metro library from here.

An example of what I am suggesting.
