This one is missing sources. They claim they'll add it on the page some time in the future.
I have registered with dev.java.net, but I cannot view the pages. I have mailed the webmaster for help, but no reply yet.
Fixed login problems, submitted a bug report. Dalibor Topic thinks http://www.amberarcher.org/ contains a free replacement to SAAJ, but sadly it's discontinued.
Another alternative would be axis itself.
Not a high priority atm.
Marking as REMIND, so that it shows up on the orphaned ebuild search in the Gentoo Java Wiki.
