Hi Ali,
It looks like you want to change your mapping for InputStream, dropping
the name="stream-source" from the collection:
<mapping name="input-stream" class="gsn.beans.InputStream" >
<value name="name" field="name" style="attribute"/>
<value name="rate" field="rate" style="attribute"
usage="optional"/>
<value name="count" field="count" style="attribute"
usage="optional"/>
<value name="start-time" field="startTime" style="attribute"
usage="optional"/>
<value name="end-time" field="endTime" style="attribute"
usage="optional"/>
<collection name="stream-source" field="sources"
item-type="gsn.beans.StreamSource" />
<value field="sql" style="text" />
</mapping>
The problem with it as shown above is that you're saying the collection
itself will have an element "stream-source", then within that each
source will have its own "stream-source" element (since that's the name
you use in the StreamSource mapping). Your XML doesn't have this element
for the collection.
Also, please subscribe to the jibx-users list so your emails will get
through. Without subscribing they get held (along with all the PayPal
and BankOfAmerica account updates for JiBX ;-) ) until I remember to
check the administrative interface and sort through the accumulation of
(mostly) junk.

The problem is that, in the jibx can't parse the addressing part of the
input stream :
<addressing>
<absolute-address host="localhost"
port="1234" wrapper-id="sf"/>
</addressing>
And complains with :
Expected "stream-source" end tag, found "absolute-address" start tag

The error is strange since I explained the "addressing" element in the
configuration file. I though this is a bug, since if I move the
"addressing" definition to the first "mapping" it starts works.
Any suggestions ?
PS - I also tried latest CVS :-(

Ali Salehi
