Eclipse – I can’t start Tomcat Server using Eclipse

eclipsejakarta-eetomcat

I simply defined a new Server using Eclipse Juno. I picked a folder and downloaded and installed Tomcat Server.

This is the log when I start the server: ( No deployment or anything, just server starting. ) 

Mar 10, 2013 8:38:13 PM org.apache.catalina.core.AprLifecycleListener init

INFO: Server startup in 167 ms

But when I navigate to localhost:8080 all I see is:

HTTP Status 404 - /

type Status report

message /

description The requested resource (/) is not available.

Apache Tomcat/7.0.12

I am sure that port number of the server is 8080.

Edit 1:

This is the web.xml file from the Tomcat Folder that is downloaded:

<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
        <param-name>debug</param-name>
        <param-value>0</param-value>
    </init-param>
    <init-param>
        <param-name>listings</param-name>
        <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup> </servlet>


<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/</url-pattern> </servlet-mapping>

Edit 2:

I solved my problem:
I changed the Server Location in Eclipse from Use workspace metadata to Use Tomcat installation. Now it works..

Thanks everyone!

Don't get confused by the error code: HTTP 404 means that client (browser) was able to connect to server, but it didn't find the required resource -- in your case it's root "/".

Since you are starting Tomcat from the Eclipse environment, it doesn't publish anything but what you have defined in your "Servers"/Tomcat configuration. This behavior is well described in this FAQ: WTP Tomcat FAQ. In your case you didn't do any configuration, so there's no deployed content.

As soon as you start developing your web project, you'll be able to access any published resources.
