Answer 1

如果你想要做的只是將文本轉儲到HTML頁面，使用StringBuilder和/或創建一個額外的類與方法輸出帶有HTML標籤的文本。

如果你真的想動畫一個網站，最「簡單」的方法是使用Servlets。有關教程，請參閱下面的鏈接。

Answer 2

如果你想簡單的解決方案與詹姆斯的回答去。但是，如果您需要在應用程序甚至平臺之間異步傳輸數據（當它們不在本地時進行雙倍數據傳輸），您可能需要查看JMS api（當您使用Glassfish作爲應用程序服務器時，它非常容易，或者Apache ActiveMQ實現工作良好）。我在從webapp調用系統程序/腳本的部署中使用它，然後這些程序在完成時通過JMS報告回webapp。

或者，您也可以將該輸出轉儲到數據庫。
