It is, check the /usr/portage/dev-java/xml-commons/files/1.0_beta2-jdk15.patch and you will see that it just changes the source and target attributes in the build.xml file. The patch is not dependent on the system jdk used. In general we try to prefer noncondional patches because it makes debugging problems easier. Please also note that there is a gentoo-java mailing lists where java related questions are likely to get better answers than on gentoo-users. You should also note that most ebuilds depend on >=virtual/jre-1.4 so having 1.3 as the system jdk to emerge stuff might not work. Regards, Petteri
