Hi, Are you sure there are no javax.servlet.... imports in afvHome.jsp ?
This looks like you have there the javax. classes in jsp pages. Try Openrewrite https://docs.openrewrite.org/recipes/java/migrate/jakarta/jakartaee10 to migrate from javax to jakarta package names where needed. Note some javax package prefixes are not renamed to jakarta.
