mapping complex types

[Noé Amorim]

hello.
how can i map the return type of a webservice to a custom type in Java.
Let's say the return type from the webservice is an array, each value from the array is another array.
The return is like this:

$ret[] = array('first name' => 'Fujiwara', 'last name' => 'Takumi', 'drives' => 'AE86');
$ret[] = array('first name' => 'Takahashi', 'last name' => 'Ryosuke', 'drives' => 'RX-7 FD');
$ret[] = array('first name' => 'Fujiwara', 'last name' => 'Reisuke', 'drives' => 'RX-7 FC');
$ret[] = array('first name' => 'Itsuki', 'last name' => 'Takeuchi', 'drives' => 'Toyota Corolla Levin SR');
$ret[] = array('first name' => 'Takeshi', 'last name' => 'Nakazato', 'drives' => 'Nissan Skyline GT-R');
return $ret;

how can i map this structure on the java client side?
thanks.
