【问题描述】：
我尝试使用 Java jdk 1.7u17 在 Linux Mint 64 位 (Debian) 上运行 apache-james-3.0-beta4 服务器，但由于 JAXB 库错误，它无法正常工作。根据文档，应下载不同的 jar 文件（http://jaxb.java.net/2.1.13/JAXB2_20100510.jar）并放入 conf/lib 目录。我这样做了，但问题仍然存在。当我切换到 jdk 1.6 时，一切都开始正常了。
有人解决了这个问题吗？
这是堆栈跟踪的一部分：

【问题讨论】：
-
我没有遇到过 James 的这个问题（但我已经形成了 JBoss 的观点），要解决这个问题，您必须在任何通配符之前在类路径中明确声明 JAR 文件。也许这会有所帮助
-
看来下个beta5版本会修复issues.apache.org/jira/browse/JAMES-1450
-
不，beta5-854 也不起作用。不过堆栈跟踪不同。
