我正在将一个项目从 JBoss 迁移到 Weblogic 服务器。Java 项目使用 BlazeDS 来与 Flex 前端进行通信。它在 JBoss 上运行良好。但是，除了以下例外，我已经挣扎了几天。

flex.messaging.LocalizedException: Unable to create a parser to load messaging configuration.

整个堆栈跟踪：

与我的配置相关的更多详细信息：

Java 1.7.0_21
blazeds-4.0.0.14931
weblogic 12c (12.1.1)

我查看了 BlazeDS 源代码中的问题类。 FlexConfigurationManager.getMessagingConfiguration()崩溃，因为解析器在第 70 行为空。在第 68 行，它正在调用FlexConfigurationManager.getConfigurationParser()，但不幸的是返回空。

看起来此函数无法找到以下解析器之一...

flex.messaging.config.ApacheXPathServerConfigurationParser
flex.messaging.config.XPathServerConfigurationParser

请注意，即使网络链接的 blazeds 版本似乎是 3.0.0.544，我已经下载了该文件的最新源代码，并且几乎相同。所以我们可以参考一下。

如果有人能给我一些小提示，我将不胜感激......

提前致谢！;)

我们终于让它工作了。我们必须更正一些关于 EJB 的配置。

但最有可能问题的主要原因是gwt-dev及其底层xml-apis库的导入！
