SYNOPSIS
     wsgen [options]service endpoint implementation class

"service endpoint implementation class" should be one parameter
so it should be "service_endpoint_implementation_class".

And it should be inserted a space between "[options]" and the
second parameter for wsgen and wsimport.

SYNOPSIS
     wsimport [options]wsdl_file

For xjc's manpage, "schema file" should be "schema_file".
And the parameters are enclosed by double brackets.
I think it's OK in single bracket.

SYNOPSIS
     xjc [[ options ...]] [[ schema file / URL / dir ... ]] [[
     -b bindinfo ... ]]
