java - 升级到 WAS 8 后 ServletWrapper 未捕获异常

Question

从 RAD 7.5 > RAD 8.5 和 WAS 7 > WAS 8 升级。进行了 jar 和 JRE 引用更改，克服了所有硬编译/构建错误，并且能够启动服务器而不出现错误，并且能够到达我的应用程序的第一页。输入某些字段并单击提交后，我收到错误 - 有什么想法吗？

由于互联网上有很多帖子讨论删除 jaxp_1.1.1.jar 中找到的 SAXParser* 类(因为这些解析器位于基本 WAS 8.5 jar 中)，所以我删除了它们。但仍然没有解决问题。当我检查代码时，发送 SOAP 消息时抛出错误，因此完全有可能与解析问题有关。

有人对此有其他想法吗？

Answer 1

我最终发现我需要从包含的 jar 中删除 crimson_1.1.1.jar、xmlparser_3.3.02.jar 和 xercesImpl-2.8.0.jar。我还必须从 jaxp_1.1.1.jar 中删除解析器文件夹。这些 jar 已在较新的 WAS v8.5 标准 jar 中被取代/替换，其中 XML 格式化方法接口(interface)(至少这些方法)已被更改，导致实现发生变化。从 jaxp_1.1.1.jar 中删除解析器文件夹的表示法相同。删除后，错误消失，我的应用程序现在可以在 RAD 8.5 和 WAS 8.5.5.5 中运行。

顺便说一下，由于这与 SOAP/WSDL/XML 相关，如果您碰巧遇到以下错误 - “CWPOL0040E:客户端无法确定如何为服务配置策略 { http://soa.usbank.com/BaseCustomerService_V_3_0 }BaseCustomerService 因为在处理附加到服务的 WSDL 文档时发生以下异常 com.ibm.ws.wspolicy.UnsupportedNamespaceException”，您需要添加参数 - “-Dcom.ibm.ws .wspolicy.ignoreWSP12inPackagesWSDL=true”(连字符之前有一个前缀空格)到通用 JVM 参数列表。此错误并不总是发生，但在我的情况下却发生了。
