Tomcat unaccessible when started from eclipse

Question

I just installed eclipse and tomcat on a Windows 7. I used latest versions.

For eclipse, http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/juno/SR1/eclipse-jee-juno-SR1-win32-x86_64.zip

For tomcat, http://ftp.unicamp.br/pub/apache/tomcat/tomcat-7/v7.0.34/bin/apache-tomcat-7.0.34-windows-x64.zip (not the service version).

When I run tomcat's startup.bat, it starts up normally and I can access it on port 8080 from browser.

But I added it in eclipse, and when I start it from eclipse it reports "Started, Synchronized", and no error message is shown, but shows an error page "HTTP Status 404 - /".

If I close it in eclipse and run its startup.bat I can access it from browser again.

Eclipse has no configs at all to set, I just point tomcat's installation path.

What can I be doing wrong?

try to check the server logs, if there is an error or exception at:

.metadata\.plugins\org.eclipse.wst.server.core\tmp0\

at your eclipse work space metadata directory. anyway there should be some fail reason (exception) reported to console in eclipse IDE or server reports correct start as e.g.:

5.1.2013 17:24:25 org.apache.coyote.http11.Http11Protocol start
INFO: Starting Coyote HTTP/1.1 on http-8080
15.1.2013 17:24:25 org.apache.jk.common.ChannelSocket init
INFO: JK: ajp13 listening on /0.0.0.0:8009
15.1.2013 17:24:25 org.apache.jk.server.JkMain start
INFO: Jk running ID=0 time=0/22  config=null
15.1.2013 17:24:25 org.apache.catalina.startup.Catalina start
INFO: Server startup in 9121 ms

in that case check your servlet mapping and also check if your url root context is correct.
