All Servlets 404

[sam wootton]

Hi,

Thanks in advance for any help or advice.

I have tomcat6 running locally, on Linux.

The problem i have, is that ALL webapps are 404, apart from "/" webapp. Even tomcats "examples" webapp is 404 when i click in the link in the manager.

$CATALINA_HOME = /usr/share/tomcat6
$CATALINA_BASE = /usr/share/tomcat6

When i look in:

/var/log/tomcat6/localhost_access_log.2012-04-23.txt

I see (if i click on the "examples" webapp that comes with tomcat):

::1 - - [23/Apr/2012:21:49:41 +0100] "GET /examples HTTP/1.1" 302 -
::1 - tomcat [23/Apr/2012:21:49:41 +0100] "GET /examples/ HTTP/1.1" 404 952

When i just type localhost:8080, i get to the tomcat manager no problem. Im also running Apache webserver locally too.

Any ideas?

An example webapp i have is:

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
   version="2.5">
    <display-name>Music Finder</display-name>
    <description>
        This is a simple web application with a source code organization
        based on the recommendations of the Application Developer's Guide.
    </description>
    <servlet>
        <servlet-name>mfservice</servlet-name>
        <servlet-class>server.MFServer</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>mfservice</servlet-name>
        <url-pattern>/musicfinder</url-pattern>
    </servlet-mapping>
</web-app>

I have the dir structure:

home/sam/tomcat/webapps/musicfinder/WEB-INF/web.xml

But this is 404 too.

please try including the below tag in the web.xml file(create any index.html)
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>

Hi sailaja,

That didnt seem to do anything. I put:

<web-app>
.... existing stuff
        <welcome-file-list>
	  <welcome-file>index.html</welcome-file>
	</welcome-file-list>
</web-app>

Still have the same problem.

I think this is a bigger tomcat mapping / configuration problem, its not simply a matter of creating a default page, otherwise tomcats "example" webapp would also work?

whether the jsp-api.jar and servlet-api.jar files are set to classpath?

Normally for the first time if we run the jsp or servlets, this is the issue i faced.

i use Eclipse and tried the tomcat examples in the browser, where i had to start the tomcat server through command prompt. It worked.

and when the tomcat is running through eclipse, i got the same message error 404.

hope this will solve

[Anurag Verma]

what URL are you requesting in browser? or how are you getting the 404 error?

Until you can get Tomcat installed such that the example apps are displaying, it's a waste of time to try and get your own apps running.

Hi,

Thank you for everyones help! Really great.

I uninstalled and reinstalled tomcat, and got the example servlets working no problem (not sure what was wrong).

I had:

tomcat/webapps/musicfinder

With this, i thought that i could have the following:

<url-pattern>/musicfinder</url-pattern>

http://localhost:8080/musicfinder

but i think my tomcat knowledge is worse than i remember, because i only way i got it to work was:

<url-pattern>/MFServlet</url-pattern>

http://localhost:8080/musicfinder/MFServlet

Anyway - its working now. I still have odd situation where my Servlet is called twice (sometimes 3 times), then when i restart my machine, it returns to only being called once. It doesn't happen all of the time though.

I dont know why that is - but i guess its a separate issue.

Thanks again!

oh, and sailaja i do all my tomcat dev / admin on the command line. I dont really use GUIs.
