ArcGIS GeoEvent处理器 - javax.xml.ws.soap.SOAPFaultException：解组错误

背景

我正在使用wsimport来创建本质上是一个Java Web服务客户端，连接到返回数据集的.Net webservice（不幸的是） . 更具体地说，我正在为ESRI ArcGIS Server 10.2的GeoEvent处理器套件开发项目（入站传输），但我认为这可以通过与JAXB和WSDL绑定相关的更一般的术语来回答 . 跟我在一起，因为大学以来我没有接触过Java（10年） .

出于WSDL的目的，.Net DataSet是一种多态类型，其实际布局直到运行时才确定，在DataSet填充数据之后 . 当您想要将该Web服务与除.Net之外的任何内容一起使用时，这会导致问题 .

经过一些研究后，我设法使用 wsimport 从webservice wsdl生成 . 然后，我能够将基于Web服务的结果作为DOM的基本概念验证程序放在一起，然后将该DOM作为节点列表 .

参考：

• JAX-WS error on WSDL file: "Error resolving component 's:schema'"

• https://weblogs.java.net/blog/vivekp/archive/2007/05/how_to_deal_wit_1.html

• 关于Toolkit Bindings的部分和http://msdn.microsoft.com/en-us/magazine/cc188755.aspx中的图6

我的wsimport看起来像这样（域名已被更改以保护无辜者）：

C:\Development\ArcGIS\WSDL>wsimport -b http://www.w3.org/2001/XMLSchema.xsd -b xsd.xjb -keep -p com.somecompany.services -XadditionalHeaders http://services.somecompany.com/DataRetrieval.asmx?wsdl

问题

不幸的是，一旦我在ArcGIS GeoEvent处理器中实现，在我的概念验证中起作用的相同代码库，从Web服务获取结果就失败了 . 我的项目是ArcGIS GeoEvent处理器将控制的OSGI包的一部分 . 下面的错误如GeoEvent处理器的Apache Karaf日志中所示 .

根据错误，我的理解是我在wsimport中如何进行绑定存在问题，引用我上面列出的那些链接的通用模式 . 看起来通用模式缺少对由wsimport生成的类存在的某些元素的定义 . 当我检查wsimport的输出时，这些类看起来是正确生成的 .

由于发布限制，我没有包含WSDL，但如果需要，将包含在以后的响应中 .

我想弄清楚的是什么

• 如何解释此错误？

• 为什么在ArcGIS GeoEvent处理器中运行时，在我的基本概念验证中用于访问Web服务的相同wsimport生成代码会失败？

• 该错误提到了JAXB和SAX，我没有有意识地在概念验证或ArcGIS GeoEvent处理器项目中引用这些库中的任何一个 . 是否可以通过不同的方式处理Web服务的绑定/解组，使用ArcGIS GeoEvent处理器包装在JAXB / SAX中并且概念证明不是？

• 我该怎么做才能解决这个问题？

使用不同的自定义xsd和xjb来说明Web服务的预期模式？我不确定如何做到这一点 . 使用wsimport以外的东西来生成webservice引用类？在Java环境中为ArcGIS GeoEvent处理器调整一些东西？其他选择？提交seppuku，那不是我的问题吗？

环境细节

• JDK 7u17（1.7.0_17）64位 . ArcGIS GeoEvent处理器正在使用这个版本的JRE，所以在我意识到之前，我已经在1.7.0_51中完成了一些开发 .

• wsimport - JAX-WS RI 2.2.4-b01

• ArcGIS Server 10.2

• ArcGIS GeoEvent处理器扩展

• Karaf（由ArcGIS Geovent处理器用于运行OSGI包）
