Use java-config. > You mean re-emerge sun-jdk1.4? You will have to have /a/ 1.4 javac, not necessarily Sun's. > Is > there any other ways? Sure, write and apply a patch to tomcat that removes all uses of enum as an identifier. For extra points, submit it back to the community. Or write and apply a patch to tomcat's native build process and/or the ebuild so that '--source 1.4' and possibly '--target 1.4' is passed to javac whenever it is called. I'd say give this back to the community, too, but we probably don't want it: Passing those options unconditionally breaks backwards compatibility and forward progress. -- "If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability." -- Gentoo Developer Ciaran McCreesh
