Question

我正在将项目从JBoss迁移到Weblogic服务器。 Java项目使用BlazeDS与Flex前端进行通信。它适用于JBoss。但是，由于以下例外，我一直在苦苦挣扎几天。

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

整个堆栈跟踪：

有关我配置的更多详情：

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

我查看了BlazeDS源代码中有问题的类。 FlexConfigurationManager.getMessagingConfiguration()崩溃，因为第70行的解析器为null。在第68行，它正在调用FlexConfigurationManager.getConfigurationParser()，不幸的是，它返回null。

看起来这个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web链接的blazeds版本似乎是3.0.0.544，我已经下载了此文件的最新源代码，它几乎相同。所以我们可以参考它。

如果有人能给我一些提示，我将不胜感激......

提前致谢！ ;）

我们终于让它成功了。我们必须纠正有关EJB的一些配置。

但问题的主要原因很可能是导入 gwt-dev 及其基础 xml-apis 库！
