soap - 返回错误的 JAX-WS 服务器端 SOAPHandler 在 WebSphere v8 上获取 "Internal Error"

Question

我有一个服务器端 JAX-WS SOAPHandler (在 WebSphere v8 上)在某些情况下需要使用它在 String 变量中的 SOAP 响应来响应客户端(我们称之为 responseXml )。

当responseXml包含成功(即非错误)的 SOAP 消息，JAX-WS 正确地将响应发送到客户端。然而，当 responseXml包含 SOAP 错误消息，发生“内部错误”，并且客户端得到与 responseXml 中不同的错误响应，如下图所示:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <soapenv:Fault xmlns:axis2ns1="http://schemas.xmlsoap.org/soap/envelope/">
         <faultcode>axis2ns1:Server</faultcode>
         <faultstring>Internal Error</faultstring>
         <detail/>
      </soapenv:Fault>
   </soapenv:Body>
</soapenv:Envelope>

以下错误写入控制台:

[10/9/12 12:21:04:177 EDT] 00000025 AxisEngine    E org.apache.axis2.engine.AxisEngine receive An error was detected during JAXWS processing
                             org.apache.axis2.AxisFault: An error was detected during JAXWS processing

这是一个简化的 SOAPHandler这说明了这个问题。 (请注意，此处显示的 responseXml 的值只是一个示例。在我实际的 SOAPHandler 中，响应不是硬编码的，而是从数据库中读取的。我只是想展示最简单的示例代码。 )

package simplified.demo;

import java.io.ByteArrayInputStream;
import java.util.Set;

import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;

public class FaultyHandler implements SOAPHandler<SOAPMessageContext> {

    @Override
    public boolean handleMessage(SOAPMessageContext context) {
        Boolean outbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

        if (!outbound) {
            String responseXml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\"><soapenv:Header></soapenv:Header><soapenv:Body><soapenv:Fault><faultcode>soapenv:Server</faultcode><faultstring>ORA-01031: insufficient privileges</faultstring><detail/></soapenv:Fault></soapenv:Body></soapenv:Envelope>";
            try {
                SOAPMessage newMsg = createSOAPMessage(responseXml);
                context.setMessage(newMsg);
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }

        return (outbound);
    }

    private SOAPMessage createSOAPMessage(String responseXml) {
        try {
            ByteArrayInputStream in = new ByteArrayInputStream(responseXml.getBytes());
            MessageFactory messageFactory = MessageFactory.newInstance();
            return messageFactory.createMessage(null, in);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public boolean handleFault(SOAPMessageContext context) {
        return true;
    }

    @Override
    public Set<QName> getHeaders() {
        return null;
    }

    @Override
    public void close(MessageContext context) {
    }
}

当我对 SOAPHandler 进行编码时，我得到了完全相同的错误创建一个 SOAPFault对象(使用 SOAPFactory )并将其扔进 SOAPFaultException .

基于堆栈跟踪，我查看了 JAXWSMessageReceiver 的源代码，而且看起来在幕后，Axis2 正在寻找一个causeByException，但当然在这种情况下没有。

有谁知道为什么会发生这种情况或如何解决？谢谢!

我遇到了同样的问题，并且能够通过禁用统一故障处理来解决它(这不是错误，而是一个功能!)。

在 WAS Developer 控制台上

https://<yourhost>/<yourport>/ibm/console/login.do

按照描述做 here (对于 WAS8):

Click Servers > Server Types. , and either WebSphere application servers > server_name or WebSphere proxy servers > server_name. Next, in the Server Infrastructure section, click Java and process management > Process definition , and select either Control, Servant, or Adjunct. Then click Java virtual machine > Custom properties.

在那里，添加一个新属性 webservices.unify.faults并将值设置为 false .
