Hi Fatih, That error is basically saying that (at least part of) "jetty-server" is missing, when that's a core dependency in the main DSpace 7 POM: https://github.com/DSpace/DSpace/blob/main/pom.xml#L1392-L1396
So, this implies to me that your build/install is somehow not valid. I'm not sure why that is...maybe you have an old version of that "jetty-server" hanging around? Maybe you've somehow customized this POM? At the very least, you may want to try a rebuild using "mvn -U clean package" (-U will tell maven to try to update all your dependencies) and then redeploy via "ant update". Hopefully, that'll help fix it. If not, you may want to look closely at your upgrade and see if somehow you have old versions of JARs (from DSpace 6) in your DSpace 7 installation (if so, you should remove them and update everything to what DSpace 7 expects).

These seems compliant with prerequisites. The log output in my previous mail is from handle-server.log. In standard log files I see no errors. How can I dig more to find out what is missing?

Are there any other errors in your DSpace logs? Based on what you've provided, my best guess is you may have had a build or install error which resulted in this. Missing classes (NoClassDefFoundError) tend to result from a build problem, or maybe an upgrade problem... it's essentially saying that a class which DSpace depends on is missing from your DSpace installation. You also should verify your basic prerequisites are correct...e.g. that you are running a supported version of Java & Maven. Good luck and let us know on this list if you find any more clues or error messages.
