Good Morning,
So here is what I know of the .war file. I did not use the .war file
(octane.war) from the existing server when installed everything on the new
server. I used the .war file that the vendor sent with the latest install
files.
Attached is the list of files from the unzipped .war WEB-INF/lib directory. I
put the files side by side and you can see that the new server has one file
that does not exist on the original server, javax.mail-api-1.6.2.jar.
And the original server has two files that don’t exist on the new server,
log4j-1.2.8.jar, log4j-core.jar
Looks like the rest of the files are the same although I did not check that the
sizes of each file are the same.
Hopefully these mean something to you,
Thanks for the help,
Bill

Hi,
No, these jar files in <tomcat>/lib are tomcat related only.
Next step,
send us what is in the application war file. War file is just zip
file. Unzip it and send us list of jar files in WEB-INF/lib directory
