Tomcat doesn't find servlet
(I apologize for the strange formatting of this message. I don't know exactly how to control it.)
I'm trying to deploy a basic "Hello World" servlet into Tomcat (6.0.18) on Mac OS X Server (10.5.6).
When I try to access it. I get 404 (not found) error.
This is my web.xml file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app23.dtd">
<web-app>
<display-name>Hello World</display-name>
<description>
Just trying to get this to work.
</description>
<servlet>
<servlet-name>hello</servlet-name>
<description>
Say hello.
</description>
<servlet-class>HelloWorld</servlet-class>
<!-- Load this servlet at server startup time -->
<load-on-startup>5</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>30</session-timeout> <!-- 30 minutes -->
</session-config>
</web-app>
I'm using a slightly modified build.xml file from apache.org. Muy build.properties file has the following info:
# Context path to install application on
app.path=/helloworld
# Tomcat 6 installation directory
catalina.home=/Library/Tomcat
The servlet java source is pulled form the example servlets:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello World!</title>");
out.println("</head>");
out.println("<body>");
out.println("Hello World!");
out.println("</body>");
out.println("</html>");
When I deploy the web app via 'ant install', ant responds with:
install:
[deploy] OK - Deployed application at context path /helloworld
The Tomcat Web Application manager shows an entry with a path of /helloworld, which links to http://eyemac.saintmarys.edu:8080/helloworld .
Noticeably absent is the Display Name, which I have set to "Hello World" in web.xml.
Clicking on the /helloworld link gives be a 404 error.
I've tried things like setting the url-pattern to something like "/hi" then going to http://eyemac.saintmarys.edu:8080/helloworld/hi (or even http://eyemac.saintmarys.edu:8080/hi) but this still results in a 404 error.
What am I doing wrong?
I'll post my build.xml and server.xml files, if that would help.
Thank you.

If I put an index.html file in WEB-INF and redeploy the web app, I can access that web page via the link in the Tomcat Web Application manager at http://eyemac.saintmarys.edu:8080/helloworld/.
I currently have the following servlet and servlet mapping in web.xml:
<servlet>
<servlet-name>hello</servlet-name>
<description>
Say hello.
</description>
<servlet-class>HelloWorld</servlet-class>
<!-- Load this servlet at server startup time -->
<load-on-startup>5</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>hi</url-pattern>
</servlet-mapping>
If I go to http://eyemac.saintmarys.edu:8080/helloworld/hi or (on the server) http://localhost:8080/helloworld/hi, I get a 404 error.
And Tomcat Web Application manager still doesn't show this web app's Display Name.

Tomcat can't find servlet class
Hello,
I am trying to forward information from a jsp page to a servlet (the example in JSPIntro.pdf). I keep getting the error that the servlet class can't be found. I have put it in webapps/examples/web-inf/classes. I also added the servlet name in several web.xml files in different directories to no avail. Can anyone give me a hint on setup.
Thanksto setup correctly the servlet you need something like this int the web.xml
<servlet>
<servlet-name>yourservlet</servlet-name>
<servlet-class>xx.yyy.zzz.yourservlet</servlet-class>
<init-param>
</servlet>
and you must put the class under
WEB_INF/lib/xx/yyyy/zzz directory of your context.
the servlet must be called as
http://yourhost/yourcontext/servlet/yourservlet
hope it helps,

I have a new computer and I have installed the latest version of Tomcat but kept the old free version of the Sun One Studio which I still had a setup file for (as I couldn't find it on this site anywhere for free anymore). The new version of Tomcat puts my webapps in a different area now being s1studio\tomcat401\webapps but there is another area for the server: C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\tomcat-docs. I use the first directory and that shows my jsp's etc but it doesn't find my servlets.
My problem I am having is that my log file is showing this:

and so it goes on.
My classes are in the directory as:
C:\Program Files\s1studio_jdk\s1studio\tomcat401\webapps\ROOT\servervirtualward\WEB-INF\classes\virtualward\java
and my web.xml is here: C:\Program Files\s1studio_jdk\s1studio\tomcat401\webapps\ROOT\servervirtualward\WEB-INF
and the code for the CourseList servlet is:
<servlet>
<servlet-name>virtualward.java.CourseList</servlet-name>
<servlet-class>virtualward.java.CourseList</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>virtualward.java.CourseList</servlet-name>
<url-pattern>/servlet/CourseList</url-pattern>
</servlet-mapping>The example servlets work fine and all .jsp's work within my project.
Can anyone spot what's wrong?
Thanks!!!I did a basic .jsp page and that worked so at least that's something. Here is my code for the .jsp that won't work. It worked perfectly on my old computer on the configuration with Tomcat4
<%@page import="virtualward.java.Student"%>
<jsp:useBean id="student" class="virtualward.java.Student" scope="session"/>
<%
String error = null; // set the error message to null for the initial visit
//to the page
if (request.getParameter("SUBMITTED") != null)
Student s = Student.findStudent(request.getParameter("userid"));
if (s == null)
error = "Login ID not found, please try again.";
else
//if the input password = the stored password
if (request.getParameter("userpword").equals(s.getPWord()))
//if login priviledges are 1 give them student access
if (s.getPrivilegeLevel()==1)
//store the details of that students details in a session from the object.
session.setAttribute("student", s);
//go to the page to display the details
response.sendRedirect("stuProfile.jsp");
} //if login priviledges are 2 or 3 direct them to a page that
//gives them Lecturer priviledges
else if (s.getPrivilegeLevel()==2 || s.getPrivilegeLevel()==3)
//store the details of that students details in a session from the object.
session.setAttribute("student", s);
//go to the page to display the details
//response.sendRedirect("selectProfile.jsp"); //old link
response.sendRedirect("maintenance/courseIdenti.jsp");
else
error = "Invalid Password";

Wrapper cannot find servlet class error
Hi all!
I'm receiving a mysterious error when I try to run my web ap. "Wrapper cannot find servlet class com.ruffalocody.report.ReportServlet or a class it depends on"
I'm running it on JBoss 3.2.7, and I have another web ap, made almost identical to this one which does not display the same error/exception.
If anyone could give me advice on what I should do to fix this, I'd very much appreciate it. :)

}Thanks :)I'm curious. Could you strip off the "java." part of the package, so both in your sourcefile as in the directory structure? It may be that the java package is not allowed, but then I wouldn't know why you didn't get a compile error...

Cannot Find Servlet class Error
Hello Everybody,
i have written a simple servlet and compiled it using j2sdk1.4 version and jsdk.jar.But when i try to load the servlet on the javawebserver2.0 it says it is unable to find servlet class though i have put the class file in the servlets directory.i even put the class in the classes directory.It works fine when i compile the same class using j2sdk1.3 version and jsdk.jar.
Please guide me as to what should be done to overcome this problem.
Thanks in Advance
Manikantan IyerHi mani2k_in ,
JavaWebserver2.0 --> This web server, by default uses JDK 1.1.8.
If you have compiled your classes using heigher versions, Webserver won't be able to find those classes which were added after JDK1.1.8.
That was the first problem regarding the J2sdk versions you have used.
You can override the default JVM usage of JavaWebServer2.0
Second the servlet problem.
Your environment should able to lookup the classes dyanmically jsdk.jar or servlet.jar.
If you are able to compile the servlet successfully, place it in servlets directory and access the servlet from a browser using the url http://servername:portnumber/servlet/Servletclass
Although you have placed your class file in servlets directory, you should access by using servlet in the URL.
If it doesn't solve your problem, please come back with more details.
Thanks,

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,
FEDERICOTampoco 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 -
ServletException: Wrapper cannot find servlet ...
Hi,
I'm trying out a (/the first) piece of code I downloaded from a website of a book (http://books.brainysoftware.com/index.php?show=struts)
I got the following exception:

As I'm new to this subject I think there is something wrong in my configuration. If you think I'm correct, could you point out what is wrong?

My ipad doesn't find my printer....
How do I make my hp 3510 discoverable to my ipad? The wireless printing works from my laptop which has the same wifi settings, but the ipad cannot find the printer????
Hi Kiwisteve77,
I understand the Ipad doesn't find the printer.
Thank you for your reply.
I will be happy to help you with this.
Try turning the wi-fi off and on again on the Ipad.
If that doesn't work turn the Ipad off and on again.
Check to make sure it is connected to the proper network.
Power cycle the router, Ipad and the printer and try it again if you are still having issues.
I have provided a document for How to Use Apple's AirPrint Over a Wireless Network. Go to the section What if a 'No AirPrint Printers Found' message displays on my Apple device?
Hope this helps.
Thank you for posting on the HP Forums. Have a great day!

When I launch I photo it wants me to choose a library but it doesn't find one which is impossible, because i still have no storage. before i can clean up i want to back up them. how can i find my library?
You may very well have damaged your library - or even your system by not having adaquate storage available
And never select all of the pitcture and move them - that will destroy your library - the iPhotolibrary is a SQLite database and must always be kept intact as a single entity -
Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

ICal search doesn't find anything
when I test this by creating a future event with a particular word in it, then return to today and search for that word in the little "search" box at top right, it doesn't find that word.
Why not?I have also had long standing problems of not being able to search for calendar events, either from within iCal or Spotlight or using mdfind.
None of the suggested solutions worked for me (removing Calendar Cache file, adding and removing folders or drives to the privacy section of Spotlight to re-index, or running mdimport ~/Library/Calendars.
One clue was that mdimport -d2 ~/Library/Calendars would not even look at the individual .ics files within any .calendar/Events directory (no output). I suspected that this was due to LaunchServices not associating these files properly with iCal. My system had previously been upgraded all the way from 10.0 through 10.6.
What finally worked for me was the following, using the Terminal, rebuilding completely the LaunchServices database:
rm /Library/Caches/com.apple.LaunchServices*.csstore
*defaults delete com.apple.LaunchServices*
*sudo /System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServi ces.framework/Support/lsregister -kill*
*sudo /System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServi ces.framework/Support/lsregister -R -domain local -domain system -domain user*
(note the capital -R in the previous line.)
This step will take a few minutes to complete, with a message about I/O throttleing
reboot (not sure if that is necessary)
*mdimport -d2 ~/Library/Calendars*
This last command should now show the successful indexing of all calendar events.
After this search finally worked again for me!

Find palette doesn't find the IPCT category field
I have all my pictures by categories and suplemental categories. The "find" tool doesn't find anything if for example I type ARC (architecture), no matter if I select containing, containing all, starting or all metadata, all, etc... It seems that it doesn't search in some IPCT fields, at least in the category and suplemental category.
You are right. "find" will find IPTC entries in caption, say, but not in category. I guess it's like EXIF, where it's only make, model, serial number, artist, and software.

The "Search" function box doesn't find things that are there! Why?!
The "Search" function box doesn't find things that are there! Why? Eg: It doesnt show all my Sent and Received emails, but it will find an email that I half wrote and deleted. Unsure why or how to explain more fully.
I also don't understand if I type in "James email" or "J" into the search box and all the J / James stuff appears but it doesn't show the emails I know have been sent and I know are somewhere because I rang "James" up to check, but the search box shows random thing I am NOT looking for, even if I type in fully what I am looking for and test it by typing in full titles of things.
It also doesn't store all my sent emails in "Sent" box. Confused! I'm not sure if the "Search" box just isn't up to the job or if it is broken / i'm doing something wrong? Maybe the email address I use isn't set up properly?This can happen sometimes if the cache is not cleared correctly when items are not deleted from your device.
The only solution to this is to do a restore to clean out the cache file. -
Satellite L855D doesn't find my CD/DVD drive
Hello!
I don't know what has happened to my computer but it doesn't find CD/DVD drive anymore.
I guess I may have deleted some necessary drive but not on purpose anyway.
Is there any way to recover it?
I have tried RmvFltrs which I found from some Toshiba's tech support site via Google search but it didn't help.
It stated that it worked but my computer tells me the installation couldn't be done.
I'm not in a desperate need of the drive to work, I'm just wondering whether it is possible to make it work somehow. So if someone could help me with this I'd be more than glad.
Sincerely,
JoonasI mean that it isn't shown in "My Computer" anymore or if I try to install something from a CD it doesn't work since the drive doesn't work.
I can find it from device manager yes but it gives me this "code 52" and says the digital signature cannot be verified. There's this yellow triangle with an exclamation point in it too. Does this help at all?
Maybe you are looking for
