Is downloading Tomcat cource code and enable Tomcat debug mode the only choice to identify the root cause of such issue? But I have no access to the source code of those applications running in Tomcat (I can decompile the jar files in war files though it's a tedious). or there might be better way to figure out the cause?

This seems to be an issue with the deployed application start up. You would have to enable debug logging for the application and see the root cause.

You might also check the context.xml for the webapp and see if it's connecting to an external resource, e.g., a database. The log message explicitly mentions an Oracle jdbc driver, it may be hanging while trying to create a database connection pool.

the problem is now mitigated by a upgrade of NFS server to V4.

Tomcat7 doesn't start and show no error message

I'm facing a problem trying to start/restart tomcat7.
When I do start/restart, the service seems to be starting/restarting ok:
* Stopping Tomcat servlet engine tomcat7 [ OK ]
* Starting Tomcat servlet engine tomcat7 [ OK ]
However, checking the log, I found this:
Oct 22, 2014 11:48:14 AM org.apache.coyote.AbstractProtocol init
INFO: Initializing ProtocolHandler ["http-bio-8080"]
Oct 22, 2014 11:48:14 AM org.apache.catalina.startup.Catalina load

Oct 22, 2014 11:48:14 AM org.apache.catalina.startup.HostConfig deployDescriptor
INFO: Deploying configuration descriptor /etc/tomcat7/Catalina/localhost/manager.xml
and nothing else happens. The cpu seems to be OK and the memory too. It just got stuck in that point.
This issue appears suddenly because no change was made, no updates on tomcat or changes in the artifact that I'm trying to deploy.
What could be the problem?

Apache Tomcat will not complete startup after a certain .war File is deployed

I have a Java web application that I am trying to deploy to our company's application server. It uses spring and spring-security. Everything works correctly when I run the application in Tomcat from Eclipse but when I try and deploy the .war file into a standalone Tomcat instance the server does not even finish starting up.
These are the catalina logs from the last attempt:

INFO: Deploying configuration descriptor manager.xml
Jan 30, 2014 1:16:41 PM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive MyApp.war
And then startup stops.
These are the localhost logs:
Jan 30, 2014 1:16:46 PM org.apache.catalina.core.ApplicationContext log
INFO: Initializing Spring root WebApplicationContext
And then nothing...
All of the other log files for this last attempt are blank.
Any insight you guys might have would be greatly appreciated!

This problem was caused by not setting the JAVA_OPTS property to point to my .ini files.
I included this in my startup script:
set JAVA_OPTS= -DLOGCONFIG=%CATALINA_HOME%\conf\logging.ini -DINIFILE=%CATALINA_HOME%\conf\webapps.ini
and it ran succesfully

Sudden issue while deploying application in Openshift

Yesterday I deployed my war in openshift using the usual command git push. But when I checked the url http://nrollin-nrollin.rhcloud.com, I am seeing the error HTTP Status 404 - The requested resource is not available. I have deployed the war many times but this is the first time I am seeing this error. I have even restarted the server but no luck. I searched down the cause in openshift forum also (https://www.openshift.com/forums/openshift/jbossas-application-the-requested-resource-is-not-available), but no solution to me as such yet. The app is running good in my local PC and is developed in Spring MVC and Hibernate.
Can anyone suggest me the cause of this issue? Or do I have to create app again..?
Below are the logs :

I faced the same problem in my local system yesterday but I resolved it by cleaning it along with its directory. I think the same would be needed for Openshift tomcat server.

How to publish a Apache-Axis web service in tomcat 6.0

I have developed a simple Apache-Axis java web service using Eclipse IDE and now it works successfully. I have generated test client also which provide by the IDE automatically. I can see that deployed web service is in the IDE server node when I expand it. (I have already added the tomcat 6.0 server to the Eclipse).
But the problem is that web service is up, only if I open the Eclipse and start the server from the Eclipse server tab. If I exit from the Eclipse, web service will be down. I want to know that how can I publish my web service permanently into the tomcat server and make it always up without opening the Eclipse IDE all the time?
thank you all in advance.
note: I just figure out the prob. when I deploy the war file, it has a different name comparing to actual web service project name in eclipse. I just open up the wsdl and get the actual url from it and type it on the address bar. then its worked !. thank u very much for your help. sorry for any inconvenience...

Currently you are using Tomcat from Eclipse which will ofcourse shutdown as you close the eclipse.
Copy your war file in your tomcat/webapps/
and start tomcat /tomcat/bin/tomcat.exe [or .sh ]without depending on the eclipse
Stop Tomcat.
Delete existing deployment. If you
have previously deployed "foo.war" in
TOMCAT_HOME/webapps, then it has been
unpacked into webapps/foo/... You
must delete this directory and all
its contents. On Unix, this can be
done with rm -r
$TOMCAT_HOME/webapps/foo
Copy WAR file to
TOMCAT_HOME/webapps/.
Start Tomcat.
