java - 将应用程序从 websphere 迁移到 tomcat - 初始化程序错误

Question

我正在将应用程序从 websphere 应用程序服务器迁移到 tomcat 7.0.47。

在运行服务器 (tomcat) 时，我遇到一个无法解决的异常，因此应用程序无法启动，映射也无法正常工作。一位前雇员编写了这个应用程序，因此我不太熟悉它的代码。

我相信这个异常(exception)

java.lang.UnsupportedOperationException: This operation needs a license for Saxon-EE

是第一个异常的某种结果。

这是导致问题的 XML 部分:

    <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

有什么想法吗？

这是 Saxon-EE XML 处理器的许可问题。你可以买一个license在他们的网站上。

可能您已经拥有许可证，这就是它在 websphere 上运行的原因。您需要在您的前开发人员的邮件中或在 websphere 服务器中找到 saxon-license.lic 文件，然后到 migrate the license file to tomcat。 :

 In Tomcat, for example, the license file should be treated in the same way as free-standing (unjarred) classes, and placed in the WEB-INF/classes directory.
