looks doesn't use configured proxy...
hope me out...

i think reason why doesn't work explained in bugreport. it's 11 years old , still marked unresolved. comment says there no plans implement there might workaround:
however, axis1.x , 2.x can both switch use jakarta-commons httpclient library. should using if can, because understads http properly. if proxy support in there, either axis build pick up.
as far remember, commons http client supports proxyselector.
