Sure, write and apply a patch to tomcat that removes all uses of enum as an identifier. It needs a lot of work! Besides there is many packages behind of which tomcat dependens on.I can't be sure all of them can be compile by jdk1.5. Besides,install tomcat is a painful thing.You know,you have to download many packages manually and still there are other problems.For example: !!! jmx-1_2_1-scsl.zip not found in /usr/portage/distfiles !!! dev-java/sun-jmx-1.2.1-r1 has fetch restriction turned on. !!! This probably means that this ebuild's files must be downloaded !!! manually. See the comments in the ebuild for more information. * * Due to license restrictions, we cannot fetch the * distributables automagically. * * 1. Visit http://wwws.sun.com/software/communitysource/jmx/download.html and follow instructions * 2. Download jmx-1_2_1-scsl.zip * 3. Move file to /usr/portage/distfiles * 4. Run emerge on this package again to complete * There are several packages having the same information just as above. Is there anybody else having ever install tomcat?

So now is there anyway to emerge tomcat? Yep. Probably you need to de-install JDK 5.0 (1.5.0) and install the Gentoo approved JDK 1.4.x. Maybe i will do that since there is not anyother ways. You know, there IS a reason why there's (not yet) a JDK 5.0 in portage... Yep,i understand now!

Sure, you can emerge -C jdk 1.5 AND emerge jdk 1.4, but wouldn't it be easier to just emerge jdk 1.4 and use the java-config tool provided by Gentoo to change your system jdk?

There are several packages having the same information just as above. Is there anybody else having ever install tomcat? Do you have the same situation as me? Yes, there are a number of packages in the tree with fetch restriction turned on. Due to non-free licenses AND annoying download policies this software may not be downloaded automatically or put on any Gentoo mirror. Gentoo has a choice: do not provide these packages AT ALL, or require you do manually download them. Aren't you glad they chose the former? -- 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 pgpGqXA5mbrPq.pgp Description: PGP signature

[gentoo-user] cause jdk1.5 emerge tomcat error!
Hi!Everybody! I have emerge sun-jdk1.5.**(i download it and ebuild it by myself).Now, i want to emerge tomcat,and it is dependent of dev-java/commons-daemon-1.0.1 .But when i emerge it,errors just occur: enum in jdk1.5 is a keyword,but it is used as a variable in the dev-java/commons-daemon-1.0.1. So now is there anyway to emerge tomcat? Thanks in advance! -- wcw -- gentoo-user@gentoo.org mailing list
