我正在使用 JBOSS 5.1.0.GA 和休眠

当我尝试连接到数据库时，出现以下错误

10:21:03,042 INFO  [Version] Hibernate Commons Annotations 3.1.0.GA

然后

我有以下依赖项：-

休眠注释 3.4.0.GA 休眠公共注释 3.1.0.GA 休眠核心 3.3.0.SP1

我怀疑我在 jboss lib 中的一个 jar 和我的依赖项中的一个 jar 之间存在冲突。谁能建议它可能是什么？

尝试在 JBoss 5.0.1 中运行 Hibernate 4.0.0.CR6 时，我遇到了同样的错误。

Hibernate 解析配置文件所需的解析器似乎是由 jboss 认可的库（我相信/lib/endorsed/xercesImpl.jar）提供的，并且 hibernate 的 xml-apis 依赖性以某种方式干扰了它们。

未在生成的存档（在我的情况下为 .war）中打包 xml-apis .jar 原来可以解决问题。为此，我在生成存档的项目的 .pom 中覆盖了依赖项的范围（覆盖其他任何地方都不会这样做，因为提供的范围不是可传递的）：

<dependency>
  <groupId>xml-apis</groupId>
  <artifactId>xml-apis</artifactId>
  <version>1.0.b2</version>
  <scope>provided</scope>
</dependency>
