When I run the project, the JSP works: Buttons and textbox appears. 当我运行项目时，JSP可以工作：按钮和文本框出现。 But when I enter a number ın a textbox and click button, I get this error: 但是，当我在文本框中输入数字并单击按钮时，出现此错误：

HTTP Status 404 - 
/WebService/services/Web_Service/FahrenheitToCelsius

type Status report

message /WebService/services/Web_Service/FahrenheitToCelsius

description The requested resource is not available.

Apache Tomcat/6.0.37

Why does Apache Tomcat say "The requested resource is not available"? 为什么Apache Tomcat会说“请求的资源不可用”？ What can I do for this error? 对于此错误，我该怎么办？

There is a incorrect web service call. Web服务调用不正确。 You have to set up some page for action property of form. 您必须为表单的action属性设置一些页面。 The page can to do web service call. 该页面可以进行Web服务调用。
