If that doesn't work, the jbossxb version number that it's looking for should be picked up from the microcontainer parent. Make sure that this parent pom is up to date with svn and includes the jbossxb dependency in the dependencyManagement section. It was my mistake, my IDE doesn't update files in project's root directory (strange, but real ;-). Thanks for the help and also to Kevin, who also realized what the problem is.
