Have you looked in Tomcat's log files for errors?  Do you have logging in your web app?

Hope this suffices for  the immediate confirmation as to where the error exists.

Please help me if this is ok if not a very simple example withe war file that can be toncatted successfuuly will be very favourable.
There is no tomcat-logger specific  excepting that is shown in properties list as above

Thanks

Hi
The web applcation and other details were  totally retried and sucesfully obtained pet.ear that was once more deployed at Tomcat7.The following was the resut
***************
Server  Error404 - File or directory not found.
The resource you are looking for might have been removed,
had its name changed, or is temporarily unavailable.

Please help if you have any other example to demo

This is what I'd recommend:

1) Completely stop your app
2) Go to C:\Program Files\java\bin\apache-maven-3.3.9-bin\bin\Tomcat 7.0\logs and remove all files
3) Restart your app and run until you hit an error or it becomes unresponsive
4) Look at the log files in the logs directory.  They should contain useful information about what is going wrong.

As a side note, why do you have Tomcat7 in the Maven bin in the Java bin?

It looks like Tomcat is starting without errors.  Can you start the Tomcat manager from your browser?

Hi

C:\Program Files\java\bin\apache-maven-3.3.9-bin\bin\Tomcat 7.0\bin>tomcat7 start:chap8.war

This is a profoundly weird directory path. What on earth is Maven doing inside the JRE installation? And what is Tomcat doing inside of the Maven installation? What is the "tomcat7" executable you're using?

[Knute Snortum]

Okay, let's backup and try this:

Start the Tomcat Monitor

at the command line, cd to the tomcat bin directory

type: tomcat7w (note the "w" at the end)

Check the status of the Tomcat7 service

double-click the Tomcat7 Monitor icon in the system tray.  It has "play" button with a circle around it.

click the General tab

if the status isn't "started", click the start button

in your web browser, type: http://localhost:8080/

you should see the Apache Tomcat page

Tell me how far you get through this.

If you don't get to the displaying the Apache Tomcat page, go to https://tomcat.apache.org/tomcat-7.0-doc/ and read the first three guides.

Hi
Subsquent to revamping the location of Tomcatas well as ant  to ease its grab for an easy and simple class path while
executing its task,thus replaing the are cogested location,the tomcat7monitor was initialised the output is
quite good with full documented guidelines and the results are s under for my original try target to deploy an executable jar created by bt ant at its new location

I don't know what's causing the error, but you don't have to start tomcat at the command line.  You start it with the Tomcat Monitor, then check it by entering http://localhost:8080/ in your browser.
