javax.servlet.ServletException：javax.servlet.jsp.JspException：找不到bean

我正在尝试构建一个简单的struts应用程序，我尝试使用表单bean将java操作中的字符串值打印到jsp。

first.jsp

        Welcome!!!!!!!!    

struts-config.xml中

myForm.java

 package com; public class myForm extends org.apache.struts.action.ActionForm { private String st; public String getSt() { return st; } public void setSt(String st) { this.st=st; } public myForm(String st) { this.st=st; } } 

myAction.java

 package com; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts.action.Action; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping; import com.myForm; public class myAction extends org.apache.struts.action.Action { public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { myForm form1=(myForm) form; String s="Karthikeyan"; System.out.println("Hello "+s); form1.setSt(s); //RequestDispatcher reqDispatcher = getRequestDispatcher("view.jsp"); //reqDispatcher.forward(request,response); return (mapping.findForward("success")); } } 

这些是重要的文件，因此我没有添加文件web.xml和view.jsp，因为我确定错误与我发布的文件代码有关。 我得到的错误是：

 javax.servlet.ServletException: javax.servlet.jsp.JspException: Cannot find bean: "myForm" in any scope 

我不知道为什么我遇到错误，因为我在struts-config.xml中定义它。 请帮忙。
