任何人都可以帮我解决我的weblogic服务器中的这些错误。

为什么这个例外是通用的，只显示包＆＃34;包com.sun.xml.bind＆＃34;？

最后，我们通过以下步骤找到了解决此问题的解决方案，

1）存在类似java.lang.SecurityException: sealing violation: can't seal package com.sun.xml.bind: already loaded的问题，但未找到相关的jar jaxb-impl.jar。

2）我们接受了这个jaxb-impl.jar并在classpath和流程中添加了成功。

3）如果没有在多个罐子中存在的类路径或类中加载正确的jar集合，就会出现此类问题。我们应该尝试使用与包com.sun.xml.bind

java.lang.SecurityException：密封违规：无法密封包com.sun.xml.bind：已经加载
