Background: there is an application that deployed on tomcat 8 in windows server 2008 r2. Currently the server is running and the application runs properly. The team leader told us the application is written by a programmer who already resigned the company two years ago. The program does not have any code changes after the programmer's resignation.
For some reasons, we have to change (upgrade) windows server 2008 r2 to windows server 2012 r2.
The application requires java 1.7 and tomcat 8 to run, so we installed those software in windows server 2012 r2.
We copy the war file from windows server 2008 r2 and paste in windows server 2012 r2. After copy and paste the war file, we deploy the war file in tomcat web application manager (the same action in windows server 2008 r2).
Once we deploy the war file, we try to start the application. However, when we click the "Start" button, we wait for a while and the tomcat message displays "FAIL - Application at context path/path-name could not be started".
We checked the software version, and they are same as in windows server 2008 r2.
We get confused about the message because the war file works in the windows server 2008 r2.
We check the localhost.2017-07-13.log file and we notice there are some exception. We would like post the content of the log here.

We don't understand is why the program works in windows server 2008 r2 but it does not work in windows server 2012 r2?
Currently we are still finding the source code of the program but from the log file, it mentioned about [/WEB-INF/applicationContext.xml] and [net.sourceforge.jtds.jdbc.Driver], we guess when we get the source code, we need to find the xml file and the driver, is it correct?
Grateful for your advice please. Thank you.
Edit
We just find the source code and we open the applicationContext.xml and there is a bean for net.sourceforge.jtds.jdbc.Driver. Not sure why it does not work in windows server 2012 r2.

You say (emphasis mine)
The application requires java 1.7 and tomcat 8 to run, so we installed those software in windows server 2012 r2.
We copy the war file from windows server 2008 r2 and paste in windows server 2012 r2. After copy and paste the war file, we deploy the war file in tomcat web application manager (the same action in windows server 2008 r2).
The error message says
java.lang.IllegalStateException: Could not load JDBC driver class [net.sourceforge.jtds.jdbc.Driver]
Means: You did not sufficiently reproduce the original implementation. As you might miss more than just this driver (it could just be the first to fail) I'm suggesting a full diff over both directories. Figure out what's deployed in both installations.
Hint: Tomcat has a global classpath in its lib directory, this contains code that every webapp can use.
