This happened to me once, i changed from SoapPrimitiveto Object, then cast it, and it worked. So give it a try. This is may not be relevant but if you are writing your web service indotnet, make sure you specify that in your envelop by usingenvelop.dotnet = true;
这发生在我身上一次，我从SoapPrimitive改为Object，然后投射它，它起作用了。所以试试吧。这可能无关紧要，但如果您在dotnet中编写 Web 服务，请确保在信封中使用envelop.dotnet = true;

I had the same problem and solve it like Hymany Nguyen said.
Here is the example, hope it helps!
我遇到了同样的问题，并像 Hymany Nguyen 所说的那样解决了它。
下面是例子，希望对你有帮助！
Replace:
代替：
SoapPrimitive resultRequestSOAP = null;
by
经过
Object resultRequestSOAP = null;
and replace:
并替换：
resultRequestSOAP = (SoapPrimitive) envelope.getResponse();
by
经过
resultRequestSOAP = (Object) envelope.getResponse();
回答by unalCTR
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
string result = response.toString();
