This happens with BIRT 4.12, 4.13 and 4.15 - found here: https://download.eclipse.org/birt/updates/release/4.14.0/index.html

What's wrong? Thank you for help in advance.

The BIRT 4.14 release and the versions before doesn't support Tomcat 10.x
This is caused in the usage of JarkartaEE at Tomcat 10.x.
But BIRT is currently not migrated to JarkartaEE. The BIRT-viewer contains J2EE componends and this will cause the issues.

Some teams of the community modified BIRT 4.14 to get is runable under Tomcat 10 but this isn't currently supported by default.

You can take a look here: #1172

[beccon4]

So with Tomcat 8 it should work?

[brush]

yes, tomcat8 or tomcat9 should not give you this error. (admittedly, i'm currently having some issues with a tomcat9 + birt 4.14 runtime, though it's not throwing errors on startup. but... that's another issue, literally!)

[speckyspooky]

Yes, I can confirm too, BIRT 4.14 is runable with Tomcat 8.x and 9.x.
