CORBA doesn't support dictionaries.<BR>
<BR>
One way to transfer python dictionaries across CORBA is to convert the<BR>
dictionary to a sequence of CORBA structs, where each struct represents<BR>
a (key, value) pair. The dictionary can be reassembled from this at the<BR>
other end.<BR>
<BR>
You can see which types are available for use with CORBA by checking out<BR>
section 3.11 of the CORBA spec:<BR>

<BR>
... and you can figure out how these CORBA types map to python by<BR>
checking out section 1.3 of the python language mapping:<BR>
