Java project is not running on tomcat server from tomcat manager after deploying war file to webapps?

Question

I have made a project on spring tool suit. This project is running fine in local embaded tomcat server. But when I deployed the war file to the external tomcat servers webapps folder I cannot run the project from the tomcat manager. When I click start it shows two errors: FAIL - Application at context path [/payemntmodule] could not be started FAIL - Encountered exception [org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/paymentmodule]]]

Here are the details of my project:

The details of the error can be found in the log files, please add them to your question. — Piotr P. Karwasz
Can you please tell me how can I check the log files in the tomcat server? @PiotrP.Karwasz — travel
The logs are in the /opt/tomcat/logs directory. A deployment error should be in localhost.<date>.log, but check also catalina.<date>.log and manager.<date>.log. — Piotr P. Karwasz
I have added the logs in my question. Can you please help me by looking at the logs? @PiotrP.Karwasz — travel
Please don't add logs and other text information as images! Add them as text (copy/paste). The images you posted lack cut the end of the error messages (the real cause is at the end) and are not searchable. — Piotr P. Karwasz

This is because your app does not knows that it is invoked by external tomcat. Need to change scope to provided,add this in pom and check

<dependency>
<groupId>org.springframework.boot</groupId>  
<artifactId>spring-boot-starter-tomcat</artifactId>  
<scope>provided</scope>
</dependency>
