how Tomcat needs package name in front of the class after import?

Dear experts,

I move my application from my machine to production server running tomcat3.1 and found some codes are not working any more.

I am getting this error:

org.apache.jasper.JasperException: Unable to compile class for JSPNote: sun.tools.javac.Main has been deprecated.
E:\apps\tomcat\work\localhost_8080%2Fpolym\_0002falign_0002dresult_00033_0002ejspalign_0002dresult3_jsp_0.java:89: Class Hashtable not found.
Hashtable ad = (Hashtable)request.getAttribute("disclist");

If I add package name in front of the Hashtable, it will work. So, why the import statement not working?

<%@ page
import="java.util.*"
import="java.io.*"
import="java.lang.Math"
errorPage="ExceptionHandler.jsp"
%>

Thanks. Is this a Tomcat 3 problem?

Thanks. One thing I don't understand is the same codes work fine on my own machine...only the Tomcat version is different.

Aha! Thanks kennethxu. I though it might be something like that, but I haven't used anything earlier than Tomcat 4, so it would only have been a guess if I had posted that ;-)

changcy77, split the points - 20 each - I might have provided a solution, but kennethxu actually explained it ;-)

my bad, didn't check exactly
>> <%@ page import="java.util.*, import="java.io.*, import="java.lang.Math" %>
this is incorrect and it should be:
<%@ page import="java.util.*, java.io.*, java.lang.Math" %>

if you still have problem, post your code and we'll fix it for you.

I have just tested on Tomcat 3.2 and 3.3 ( don't have 3.1 on hand) both import works!

<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>
<%=new Date() %><p>
<%=new IOException( "works?" )%>

-- or --

<%@ page import="java.io.*, java.util.*" %>
<%=new Date() %><p>
<%=new IOException( "works?" )%>
