我有一个使用远程soap服务的soap客户端。连接和设置一切正常。当我发送soap请求时,我会收到一条soap错误消息,如下所示:Java 获取soap:使用soap服务时出错,java,web-services,soap,jax-ws,Java,Web Services,Soap,Jax Ws,我有一个使用远程soap服务的soap客户端。连接和设置一切正常。当我发送soap请求时,我会收到一条soap错误消息,如下所示: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <soap:Fault> <faultcode>soap:Server</faultcode> <faults

诸如
索引:0、大小:0等消息通常是由索引自动边界异常引起的
在你的情况下,这可能意味着:
- 请求为空
- 请求的编码错误
- 安全机制不允许您的请求通过
- 后端中存在一个
IndexOutOfBoundsException
下一步:
检查服务器是否接受来自的请求
- 您可以完全控制请求,因此如果出现问题,可能是后端出错
- 如果有效,你的客户就有问题了。检查客户端正在发送的请求。完成了吗?它是否包含不可读的字符
结果:使用SoapUI时也会发生此错误
XML/XML模式
XML和XML模式中的一些东西吸引了我的注意
- 在请求中,仅
createRequest
使用名称空间。其他元素没有名称空间,因为它们没有指定名称空间前缀。使用
将为createRequest
下面的所有元素分配一个默认名称空间
- (在XML模式中有一个对
type=“tns:dataFields”
的引用,尽管只有dataField
。另外createRequest
是小写,而在请求中它是用驼峰大小写的。我认为这两个都不是真正的问题,因为您更改了StackOverflow的名称。)
服务器错误
由于无法发送服务器接受的任何请求(即使使用SoapUI也不行),因此您必须调试服务器
- 日志中是否有任何错误消息
- 异常发生在哪里?在
java.lang.Exception
上设置一个断点,并缩小范围,直到找到问题
soap:Server是否表示错误来自服务器端。请注意,该服务确实在其后端访问数据库。我在SoapUI上尝试了相同的请求信封,但我得到了相同的错误。我为混淆感到抱歉,这些都是我的错误。我只是编辑了wsdl,所以没有人会感到困惑。我查看了服务器日志。我在那里发现了相同的错误“IndexOutOfBoundException”。谢谢你,我终于找到了问题所在。我在SOAP请求中发送的“requestTypeCode”的值在数据库中不存在,并且由于该类型代码无法映射到数据库表中的任何值中,因此它发送了IndexOutOfBound异常。非常感谢您帮助我调试此问题。您能粘贴您发送的请求吗?我刚刚编辑了问题并将其添加到上面。很抱歉之前没有添加它。@Ashish,您是否也可以检查您在服务器端得到的所有异常。我在这里附加了wsdl的一部分。谢谢你的帮助。
