HTTP Status 404 - / description The requested resource (/) is not available

hi all,
i am new to java and i have installed "eclipse-jee-helios-SR2-win32" on my system.
I have installed Tomcat ,and i have done with all the primary settings and i have added the server.
when i start tomcat from eclipse it starts sucessfully but the home page of Tomcat is not appearing.
when i start tomcat manually(not from eclipse), it start and i get the home page too,
but at the same time i try to start it from eclipse i get below error.
Several ports (8080, 8009) required by Tomcat v6.0 Server at localhost are already in use.*
The server may already be running in another process, or a system process may be using the port.*
To start this server you will need to stop the other process or change the port number(s).*
please let me know how to come out of this problem.
let me know if you need more information to work on this issue.
thanks.

please let me know if you can help me.Well, you should create a .war of your project and deploy it on tomcat. Now you're relying too much on Eclipse's functionality, being completely helpless when Eclipse suddenly fails to start tomcat for you.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

404 'the requested resource is not available'

Hi All,
We created a KM iview and accessing Flash file. Some users are able to see the iview without error. Some users are getting 404 'the requested resource is not available' Error. They are not able to see the flash file in portal.
Can anyone advise me what the problem is and resolution steps for this?
Thanks,
Srinivasu.Y

Hi Srinivasu,
Well you already have lots of valid suggestions above but this problem might be causing for various reasons. As you have already checked the permissions for the set of the users having this problem, it might be worth checking if there are many nodes of the server instance and if any of these are not working properly. It can happen that when those set of users are trying to access the resource, the request is hitting specific server nodes which is unable to find the resource for some reasons. You can try asking the users to clear their browser cache and try again so that when the users try to access the same resource again it might go to different node this time.
But probably this is a temporary solution that might work as has worked in my case but there might be problem with some server nodes which is worth looking at.
Hope it helps.

Gourav

[TOMCAT] [SERVLET] : The requested resource () is not available.

Hi!! I'm looking for an answer to my problem, and I'm going to explain what I mean.
I've created a .jar named yuhuuTunnel.jar that has the following structure:
yuhuuTunnel.jar:
--> web (contains the servlets)
      --> *.class
      --> HelloWorldServlet.class
--> META-INF
      --> MANIFEST.MF
--> SimpleClient.classThe code of HelloWorldServlet.java is this:
    package web;
    import java.io.IOException;
    import java.io.PrintWriter;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.ServletException;
    import javax.servlet.ServletConfig;
    public class HelloWorldServlet extends HttpServlet {
        public void init(ServletConfig config) throws ServletException {
            super.init(config);
        public void doGet( HttpServletRequest request, HttpServletResponse response )
                throws ServletException, IOException {
            doPost(request, response);
        public void doPost( HttpServletRequest request, HttpServletResponse response)
                throws ServletException, IOException {
            response.setContentType("text/html");
            PrintWriter out = response.getWriter();
            out.println("<html>");
            out.println("<body>");
            out.println("<body bgcolor=\"white\">");
            out.println("<h1>Yuhuu Servlet!</h1>");
            out.println("</body>");
            out.println("</html>");
    }then, using a .war file (created with ANT), I've created into /../tomcat/webapps/ a directory call yuhuuTunnel that has this structure:
    /webapps/
          --> yuhuuTunnel
                --> WEB-INF
                        --> web.xml
                        --> lib
                             --> yuhuuTunnel.jar
                --> META-INF
                        --> MANIFEST.MF
                             --> yuhuuTunnel.jar

    </web-app>Tomcat works correctly ( http://localhost:8080 return me the page of tomcat ) but when I try to use the HelloWoldServlet typing http://localhost:8080/yuhuuTunnel/HelloWorld into a browser, this one returns me the HTTP Status 404 - The requested resource () is not available.
What is wrong? The address that I type into the browser or there's an error into web.xml?
Something interesting: If I type
http://localhost:8080/yuhuuTunnel/HelloWorld
the message given back is: "The requested resource () is not available."
but if I type
http://localhost:8080/HelloWorld the message is different:
"The requested resource (/HelloWorld) is not available."

out.println("<body> Hello "+name+" good morning </body>");
out.println("</html>");
Please let me know why am I getting this error.
Thanks in advance

Your servlets MUST be packaged, they cannot be part of the root package. And your action should be /Myservlet/HelloName.

"404 Error - The requested resource does not exist" found in portal for Collaboration room

Hi Experts,
I am trying to resolve this issue since a week but not able to solve it, so i need your help.
The Problem is when i assign a collaboration room to a user, the room is assigned but when the user clicks on the room link it gives the "404 Error - The requested resource doesn't exist". But if a new room is created and give access to the user, the user is able to open the new room through the link and view the documents.
The Unique thing about the error is, it doesn't occur for every user it happens with few users, since I am the super_admin I am able to view all the rooms without getting such "404 error" even for once.
I have tried by setting up all the permissions to the room and also assigning Everyone role to the rooms, still the problem persists.
I am unable to find a solution for this, so need your help.
Eagerly waiting for your helpful replies.
Thanks in advance.
Thanks & Regards,
Shumana.

Hi
Try with following link (VC should be in Caps) -
http://localhost:50400/VC/default.jsp
Also check whether you have proper admin roles assigned to your user id.
Regards

HTTP 404 THE REQUESTED RESOURCE IS NOT AVAILABLE

HELP ME PLEASE !!!!
I HAVE AN APPLICATION THAT USES 3 PAGES: INDEX.HTML , MOTOR.JSP AND MOTOR2.JSP.
THE LOGIC OF APPLICATION IS:
FIRST STEP
THE FIRST STEP IS SHOWING PAGE INDEX.HTML
THERE IS THE FOLLOWING CODE IN THIS PAGE:
<FORM ACTION="DIRECT">
SECOND STEP
DIRECT IS A SERVLET THAT HAVE THE FOLLOWING CODE:
RequestDispatcher rd = req.getRequestDispatcher("Motor.jsp");
rd.forward(req,res);
THIRD STEP
THE PAGE MOTOR.JSP REDIRECT TO A SERVLET ENGINE,
AND SERVLET ENGINE REDIRECT TO A JSP MOTOR2.JSP
USING THE COMMAND:
RequestDispatcher rd = req.getRequestDispatcher("Motor2.jsp");
rd.forward(req,res);
IN THIS THIRD STEP THE PAGE IS ALWAYS REFRESHING
TO ADD INFORMATION TO THE PAGE MOTOR2.JSP.
SOMETIMES THE APPLICATION SHOWS ALL PAGES,
BUT, SOMETIMES THE APPLICATION HAS AN ERROR:
HTTP 404 - THE REQUESTED RESOURCE (/MOTOR2.JSP)
IS NOT AVAILABLE
I�M RUNNING THE APPLICATION IN TOMCAT 4.1.27
IS ANYTHING WRONG WITH THE COMMANDS TO
REDIRECT THE PAGES?
PLEASE HELP ME
THANKS VERY MUCH
JANE PELLIM

Hi,
the refresh of the page is about 2 minutes, because some info
about the process that is running in background
is showing in the motor2 jsp.
the redirects is necessary because in each page
some processing is running in the servlets.

Error 404: the request resource is not available

Hello,
I'm a newbie am using the Sun One (Forte 4.0 Community Edition) to develop a JSP/Servlet application.
I'm using the built-in version of Tomcat, that comes with forte. Tomcat has been installed in tyhe following directory:
C:\forte\forte4j\tomcat401
My application has the following path:
C:\forte\RDoku\tomcat401_base\webapps\designer
After reading the documentation that comes with this version of Forte, it seems that Tomcat can be configured to work this
way. Is that correct?
Anyway, when I start tomcat(within forte), the login page, login.jsp is loaded successfully. The action of the login
form is servlet/com.doku.login. My web.xml file looks like this:
<?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-app_2_3.dtd">
<web-app>

<servlet>
<servlet-name>login</servlet-name>
<servlet-class>com.doku.login</servlet-class>
</servlet>
</web-app>
My problem is that when I submit the form, I get the following error:
Error 404, /servlet/com.doku.login, the request resource (/servlet/com.doku.login) is not available.
I would really appreciate it if anyone could help me in solving this mystery.
Regards,
Rudi

Hey Rudi
Everything seems to be in place ..except your package structure..
your webapp has the context of designer.
Therfore your directory structure for tomcat should look somewhat like this
webapps
--designer
web-inf < web.xml(i think)
classes <Place your class files here(if loose)
lib < jar files
1.) Somehow tomcat is creating another context in servlet (unless you have created one yourself).I would urge u to check the invocation for your webapp (By saying that i am pointing at the error /servlet/com.doku.login...instead of /designer/com.doku.login).
change the action of the form to
/designer/...instead of /servlet/
2.)Further..on examining your depoyment descriptor..i found missing entries for the <servlet-mapping> element.Tomcat uses your deployment descriptor to map the incoming requests to your classes.The element must be specified in order to allow a smooth mapping from the request to the corresponding servlet class.
Let me explain by using an example
a.)my form action="/designer/Hello" method="get"
b.)The directory structure for my webapp(designer ) is as above
c.)web.xml
<?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-app_2_3.dtd">
<web-app>

<servlet>
<servlet-name>Hello</servlet-name>
<servlet-class>package.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Hello</servlet-name>
<url-pattern>/Hello</url-pattern>
</servlet-mapping>
</web-app>
so for all incoming requests in the form /servlet/Hello will be mapped to your class defined in the package package.HelloWorld
Let me know if u have more questions.
