There is 5 different packages on AUR: jboss-web [1] : version 2.1.9 jboss [2] : version 5.1.0 jboss4 [3] : version 4.2.3 jboss6 [4] : version 6.0.0 jboss7 [5] : version 7.0.1 While I may understand the need for older versions in some case (is there?), the naming scheme make little sense to me. Why jboss [2] is not the latest version (ie 7) ? jboss-web [1] does not seems right either. What do you think ?
