如何解决SAXException：in中的元素无效 [英] How to solve SAXException: Invalid element in

问题描述

我尝试通过以下方式从Web服务获取结果。

I try to get results from a webservice in the following way.

List result = new Vector();
LibrarySearchRequest request = new LibrarySearchRequest(queryString);
LibrarySearchServicePortTypeProxy proxy = 
                                new LibrarySearchServicePortTypeProxy();
LibrarySearchServicePortType port = proxy.getLibrarySearchServicePortType();
LibrarySearchResponse response = port.process(request);
librarysearch.soft.Book[] books = response.getBooks();

当我这样做时，我得到以下异常（stacktrace）：

When I do this I get the following exception (stacktrace) :

org.xml.sax.SAXException: Invalid element in librarysearch.soft.Book - book

The regular database has caught an unexpected exception: ; nested exception is: 
org.xml.sax.SAXException: Invalid element in librarysearch.soft.Book - book

我读到的问题可能是由webservice返回的结果与wsdl生成的类不匹配引起的。我重新生成了我的webservice客户端但没有成功。还有什么可能是问题？

I read the problem could be caused by the result returned from the webservice not matching with the classes generated from the wsdl. I regenerated my webservice client but no succes. What else could be the problem?

推荐答案

这可能与此错误有关（ AXIS-2758 ），未解决Axis 1.x。

This could be related to this bug (AXIS-2758), unresolved with Axis 1.x.

如果客户端存根与服务器端（WSDL文件）不是最新的，则会出现此问题。你可能不得不重新生成它。
与 axistools：wsdl2java 一样。

This problem can appear if your client stub is not up to date with the server side (the WSDL file). You could have to re-generate it. Like with axistools:wsdl2java.

现在最好的，只要你至少使用Java 6，就可以在客户端使用JAX-WS（ JAX-WS Maven插件）。但它无法使用RPC / Encoded旧的SOAP服务...更喜欢Document / Literal样式。

The best nowadays, provided you use at least Java 6, is maybe to use JAX-WS on the client side (JAX-WS Maven Plugin). But it could not work with old SOAP Services using RPC/Encoded... Prefer the Document/Literal style.
