java - 替代 JAXMServlet？

Question

我正在维护一个应用程序，该应用程序具有扩展javax.xml.messaging.JAXMServlet的类（编写于 2005 年） 。在升级到实现最新 J2EE 标准的新应用服务器时，我发现JWSDP 2.0（Java Web 服务开发包）中删除了JAXMServlet，根据这个问题（显然 JWSDP 本身也已被弃用）。它所依赖的代码自编写以来没有发生显着变化，并且是现有的大型生产系统的一部分，该代码已经经过测试和调试，因此由于回归测试的影响，我不愿意从头开始重写这些类.

这门课有“简单”的替代品吗？尽管 Google 有很多使用此代码的示例（从 2003 年到 2004 年左右），但对于替换它却出奇地沉默。谢谢。

Answer 1

为什么要更换它？为什么不找到相关的库并使用它们呢？

要回答我自己的问题，请在http://www.java.happycodings.com/Java%5fUtil%5fPackage/code23.html找到一些替换代码：
