java.lang.IllegalArgumentException: Unknown Entity bean class with eclipselink in tomcat 10

Question

Im trying to upgrade spring web app to tomcat 10 for the upgrade im using apache jakarta migration tool. the application got successfully migrated using this tool but when i run the application in tomcat 10 im facing following issue

java.lang.IllegalArgumentException: Unknown Entity bean class please verify that this class has been marked with the @Entity annotation.

and tables are not being created in the database.

when i run same application in tomcat 9 the tables are being created and i dont face any exception there.

i cant able to figure what is the problem in tomcat 10 even after using migration tool.

Answer 1

Spring 5 does not work with Tomcat 10 due to changes in Tomcat packages from javax to jakarta.
