java - 从 Myeclipse IDE 重新部署之间保持 Tomcat 服务器应用程序 session

Question

全部我正在使用 Tomcat 6.X 和 My Eclipse 开发 Web 应用程序。当我对现有的 java 文件(Java 类、SERVLETS、过滤器)进行一些更改时，我必须将它重新部署到 tomcat 服务器。但是，当我重新部署应用程序时

existing session becomes null .

有什么方法可以让我在 MY ECLISPE 的重新部署之间保留现有 session 。

Restart Persistence

Whenver Catalina is shut down normally and restarted, or when an application reload is triggered, the standard Manager implementation will attempt to serialize all currently active sessions to a disk file located via the pathname attribute. All such saved sessions will then be deserialized and activated (assuming they have not expired in the mean time) when the application reload is completed.

In order to successfully restore the state of session attributes, all such attributes MUST implement the java.io.Serializable interface. You MAY cause the Manager to enforce this restriction by including the element in your web application deployment descriptor (/WEB-INF/web.xml).
