You have the "myname" variable declared inside the try/catch statement.
Try declaring it outside of the try/catch.
<%@ page language="java" contentType="text/html"
import=" java.util.*,java.io.*,java.sql.*"%>
<%
String myname:
try{
myname = "Jason";
}catch(Exception e){
e.printStackTrace();
}
%>
<html>
<body>
This is a html, my name is <%=myname%></body>
</html>

Subject: Tomcat and JSP Issue
My tomcat works perfectly normal before today. I did nothing to it,
but now even the simplest JSP code gives errors:
whatswrong.jsp
