Tomcat doesn't start on eclipse - eclipse

Question

I have some trouble, when launching tomcat 7.0 in a Java EE project in Eclipse.I have a timeout error when starting the server.
I haven't got a clue of what is wrong.
I try to increase the timeout limit to 1800s but it doesn't change anything.
Here are the logs when tomcat try to start :

Thank you for your response

Answer 1

INFO: Server startup in 1846 ms
Specifically, Tomcat as an appserver successfully started (as indicated by the last line in your stack trace) It's the web application titled test that failed to deploy as a result of the missing dependency (the apache library) as you can see from
Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/test]]
Caused by: java.lang.NoClassDefFoundError: Lorg/apache/commons/logging/Log;
Download the missing dependency from here
To avoid future trouble, copy the commons library jars you downloaded from the link above and place them in the WEB-INF\lib folder of the test deployment package (Folder or .war file).
Alternatively,
Download and install the latest copy of the Apache Commons Logging library from the Commons site here and copy into the TOMCAT_HOME\common\lib folder (create the path if it doesn't exist). TOMCAT_HOME refers to your tomcat installation folder. Do not copy the jars into multiple locations, this will cause problems later

Answer 2

Tomcat is unable to start due to a missing dependency of an installed web application.
from your stack trace (removing the buzz :P)
...[blah blah]...
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.Log

try to remove all of your deployed web applications, and start again. If Tomcat will start, you can then try to figure out what of your webapps is causing all that mess.
