As of now axis supports ADB, xmlbeans and jibx. Currently JaxBRI (ref impl) is under experiment. Axis seems to generate mappings depending upon the kind of binder selected.
Is it true that to develop and work with axis WS, one needs to be aware of the way the selected binder works? Fx, ADB doesn't work with restrictions and complex type extensions.
Which one is generally used on projects? The default is ADB.
ADB does not implement the full features of XML Schema. xmlbeans cover the full features. xmlbeans generates lots of utility code and is considered heavy weight. ADB generates very few and considered light weight and fast. ADB generated classes has a lousy API. xmlbeans has an elegant api that makes the developers comfortable.
