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
=======================================================
<%@ page    language="java" contentType="text/html"
        import=" java.util.*,java.io.*,java.sql.*"%>
<%
        try{
                String myname = "Jason";
        }catch(Exception e){
                e.printStackTrace();
        }
%>
<html>
<body>
This is a html, my name is <%=myname%></body>
</html>
=======================================================

Here are the errors:
