Explicit method list broken in java2wsdl

The "methods" configuration parameter takes a list of methods, but
if more than one method is specified then the execution of Java2WSDL
will fail. This is because axistools generates a call like
"... -m m1 m2 m3 ..."; however, the -m option expects a single
parameter, and hence the "m2" and "m3" are taken as class-of-port-type
arguments.

Workaround: instead of using something like

<methods>
<method>m1</method>
<method>m2</method>
<method>m3</method>
</methods>

you need to supply the list in a single method element, e.g.

<methods>
<method>m1 m2 m3</method>
</methods>

Attached is a simple patch for this problem.
