Tomcat server could not start after adding the .WAR file in webapp folder

Question

This error occured after we placed the .WAR file in the Tomcat's webapp folder. Then we tried going to the following link:

http:// localhost:port/ProjectName/console

But a 404 error occurred. When we stopped the Tomcat server to restart it, we could not start the Tomcat server anymore. The following occured showed:

C:\Users\Administrator>

I also noticed this line of error:

But when we checked if the file was missing, the file is still there. worklight-jee-library.jar

Are we missing something?

Note:

Worklight Server 6.2
Apache Tomcat 8
MySQL 5.6

ALWAYS mention your Worklight version and build number. Always. — Idan Adar
Which instructions did you follow in order to deploy Worklight and the Worklight project, to Tomcat? Provide link. — Idan Adar
@IdanAdar sorry about that, I've updated the information. I'm not sure where to find the build number for the worklight server... As for the link. Here it is: pic.dhe.ibm.com/infocenter/wrklight/v5r0m6/… — AWSSET

The link you've provided in the comments points to Worklight 5.0.6, whereas you are using Worklight 6.2; You should use the correct instructions for your Worklight version. Here: http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.deploy.doc/admin/c_manually_configuring_app_server.html?lang=en

Additionally, I think that this may just be an issue of using the wrong URL.

In Worklight 6.2 the Worklight Console URL is in fact http://domain:port/worklightconsole.
Try with this URL.
