Sorry for the delay in response.
I created a new VM with Server 2025.
I didn't exactly recreate current environment because I didn't want to install
versions with known vulnerabilities. I got it as close as I could. I am still
having the same problem with sending email notifications. Here is my current
setup:
Firebird
Original Server 3.0.4.33054
New Server w/Latest Software 3.0.13.33818
New Server w/Older Software 3.0.13.33818
Java
Original Server 8
New Server w/Latest Software Microsoft JDK with Hotspot 11.0.23+9
New Server w/Older Software 8
Apache Tomcat
Original Server 9.0.16
New Server w/Latest Software 10.1.8
New Server w/Older Software 9.0.115
Here is the webpage of "errors" that comes up when I test:
HTTP Status 500 – Internal Server Error
Type Exception Report
Message An exception occurred processing [MainView.jsp] at line [85]
Description The server encountered an unexpected condition that prevented it
from fulfilling the request.

83: + sessionBeanId.getLoginStatus());
84: } else {
85: MainViewBeanId.initialize(request);
86: // MainViewBeanId.retrieveChanges(sessionBeanId);

Bill,
why are you moving to Tomcat 10 when Tomcat 9 isn't end of life yet? Did the
vendor recommend Tomcat 10 with their application?
My advice would be to only change one thing at a time and then test it.
In your case:
1. Move your old working software stack to the new machine (old java, old
tomcat, old everything) -> test it 2. Create a second tomcat 9 (download the
latest one) directory next to the old working one, stop the old tomcat and copy
everything from old-tomcat9/webapps to new-tomcat9/webapps. Also, check if any
other file is present in the old tomcat (you already mentioned you a files.xml,
etc). Also copy these files to the new tomcat directory.
Maybe even check contents of files, they may have been changed in the old
tomcat directory. Test it!
3. Update to java 11. Test it!
And so on.
Sebastian
