我有一个服务器端 JAX-WSSOAPHandler（在 WebSphere v8 上）在某些情况下需要使用字符串变量中的 SOAP 响应来响应客户端（我们称之为responseXml).
When responseXml包含成功（即非故障）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 SOAP 错误消息不同的错误响应responseXml，如下所示：
<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>
以下错误被写入控制台：
[10/9/12 12:21:04:177 EDT] 00000025 AxisEngine E org.apache.axis2.engine.AxisEngine receive An error was detected during JAXWS processing

这是一个简化的SOAPHandler这就说明了这个问题。 （请注意，值responseXml这里显示的只是一个例子。在我的实际SOAPHandler，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) {
}
}
当我编码时，我得到完全相同的错误SOAPHandler创建一个SOAPFault对象（使用SOAPFactory）并将其扔进SOAPFaultException.
根据堆栈跟踪，我查看了源代码JAXWSMessageReceiver https://svn.apache.org/repos/asf/axis/axis2/java/core/trunk/modules/jaxws/src/org/apache/axis2/jaxws/server/JAXWSMessageReceiver.java，看起来在幕后，Axis2 正在寻找 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！
