Tomcat can't detect the class file of the JApplet.

Hi,
I am relatively new in the applet field. I am trying to invoke an JApplet through JSP.
Problem is that i have to package the JApplet class files as it has to access other packages. also the JSP with the embedded JApplet exists in a different folder from the JApplet class files.
I am getting the class not found exception.
Context Path: http://localhost:8080/sncdatagate
folder structure as follows.
sncdatagate\jsp\myApplet.jsp
sncdatagate\WEB-INF\classes\datagate\ui\myApplet.class
package for myApplet.java : datagate.ui
The JSP code is as follows :-
<jsp:plugin
type="applet"
code="datagate.ui.myApplet"
codebase="/sncdatagate/"
width ="700"
height="400"
iepluginurl="http://java.sun.com/products/plugin/autodl/jinstall-1_3_1_01a-win.cab#version=1,3,1,1"
nspluginurl="http://java.sun.com/products/plugin/autodl/jinstall-1_3_1_01a-win.cab#version=1,3,1,1"
jreversion="1.3.1_01">
     <jsp:params>
                         <jsp:param name = "encodedString" value="<%=encodedString%>"/>
          </jsp:params>
</jsp:plugin>
The error on Java console is as follows:-
load: class datagate.ui.myApplet not found.
java.lang.ClassNotFoundException: java.io.FileNotFoundException: File not found: http://localhost:8080/sncdatagate/datagate/ui/myApplet.class

Kind help!
Would greatly appreciate any suggestions.
Thank You.

The WEB-INF\classes\ folder is meant for servlets and the files insides are accessed thru the "servlet/" folder. To run applets, place them outside of the web-inf folder together with your jsp files.
If your applet has a package, remember to create appropriate folders for it. Eg.
sncdatagate\jsp\myApplet.jsp
sncdatagate\datagate\ui\myApplet.class
<applet
code="datagate.ui.myApplet"
codebase="/sncdatagate/" ...

did you create the Searcher class? if so stick it in a package and put it under your web-inf directory. then use an <%@ page import="" %> statement to import the code.
if you didn't create the class is it in some jar library you downloaded? if so stick the jar file in your web-inf/lib folder.

TOMCAT CAN�T FIND BEAN CLASSE

Hello, i am from Argentina. i need URGENT help with tomcat, because i am developing my final thesis.
I have all my sources in
C:\jakarta-tomcat-5.0.16\webapps\tesis
C:\jakarta-tomcat-5.0.16\webapps\tesis\ (archivos jsp)
C:\jakarta-tomcat-5.0.16\webapps\tesis\lib
C:\jakarta-tomcat-5.0.16\webapps\tesis\web-inf\classes\edu\tesis\beans
C:\jakarta-tomcat-5.0.16\webapps\tesis\web-inf\classes\edu\tesis\queries
C:\jakarta-tomcat-5.0.16\webapps\tesis\web-inf\classes\fede\servlets
my problem is that when i execute the login.jsp through the browser in this way
http://localhost:8080/tesis/login.jsp
tomcat can�t find the edu.tesis.beans package
In compiled jsp class i can see this
package org.apache.jsp;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
import edu.tesis.beans.*;
so, the problem is that tomcat set package org.apache.jsp; to my jsp, so it can�t find edu.tesis.beans package.
This is my context path that is in $CATALINA_HOME/conf/server.xml file
<Context path="/tesis" docBase="C:\tomcat\webapps\tesis"
debug="9"
reloadable="true"
crossContext="true"/>
This is an extraction of my jsp file
<html>
<head>
<%@page import="edu.tesis.beans.*"%>
</head>
<body>
<jsp:useBean id="universidad" class="edu.tesis.beans.Universidad" scope="request" />
<form action="servlets/fede.servlets.ServletMaxwell" method="post"><BR><BR><BR><BR>
PLEASE, I NEED AN URGENT HELP!!!!
THANKS,
FEDERICO

Tampoco te preocupes porque Tomcat cambie el paquete de las p�ginas jsp. Eso es un comportamiento normal. Adem�s nota que el paquete de tu tesis es importado en la clase generada a partir del jsp, o sea que deberia encontrarla si est� en el lugar correcto.
Otra cosa que veo extra�a en tu estructura de directorios es que existe un directorio "lib" por fuera de WEB-INF. Si este contiene beans en forma de paquetes jar, deberia estar dentro de WEB-INF

Tomcat Web-server uses old .class files

Hi Friends,
My Tomcat webserver uses old .class files. The problem persists even if I delete old class files. The new ones are formed but then if i again recompile, the new-old ones are used :)
Am I doing something wrong????
Please suggest!!

I have experienced this problem before as well. Tomcat seems to cache compiled class files for better speed. To get Tomcat to reload class files that I've recently recompiled here is what I do:
1. Go into the Tomcat server administration area (http://localhost/admin)
2. Choose the context that is using the classes that you want to reload (from Service / Host)
3. Make sure reloadable is set to true
3. Click save, and then commit changes
Hope this helps, but if there is a better way to get Tomcat to use the most recent class files I would love to hear it!

WRT54GS Can not detect the router

We lost the internet connection a few days ago for a couple of hours and since then had to reset the modem and when I try to set up the router with the Easy Link Advisor I get can not detect the router. I am using the router to access the internet and it can't be detected???
I have powered it off enough times and then some and need to get this running to use the laptops.
I am running ver 7 firmware that it came with but I don't know what the exact version I am running or gor that matter where to find it.
Thanks

okay went through the firmware upgrade and installed it through 192.168.1.1 to admin tab and upgrade. it got to the reboot part and hung there for a bit, i hit continue or what ever it said and came back upwith a dns error and page unreachable. version installed is what i downloaded 7.50.5. i am still having the same problem, all the lights are lit that are suppossed to be lit, and i am on the internet and running through the router, and when i go into easylink advisor and start the setup process i have to go through the entire thing including selecting the router (which it should know what router it is) though removing the power cord and waiting and still told that it can not detect the router. i have no idea where to go from here. thanks!
