Hi Bill,
Thanks for your reply.

Here 'registered' means fetching a RendererControl from Host. I used
localRendCtl = (RendererControl
)localDisplay.getControl(RendererControl.class); to fetch
RendererControl from Host. It worked well.
This was not one of my questions. Sorry about the confusion.

Yes, I've gone through all the tutorials suggested above and invoked
most of the mothods in my application.
I mainly use the visad built-in collaboration support so far. Based on
RendererControl, all graphics widgets associated with Controls and
ScalarMaps worked very well.
I found that when a DataReference has been removed in Host, Clients
didn't response. After investagation on VisAD, it seems that
REFERENCE_REMOVED event was not sent to clients. So I made some changes
to VisAD system to make this part work. Although I knew this may bring
some trouble later on, but I have no better choice at this moment.
To those self-developed graphics widgets (e.g. ComboBox, Button etc.)
which neither belongs to Controls nor ScalarMap. I still have no idea
how to make them collaborative.
I will follow your suggestion to see if IDV's approach can be invoked in
my application.
Thank you very much.
Mike

I don't understand what 'registered with RendererControl' means? What
method are you invoking to register?

VisAD has built-in support collaboration between remote Displays, as
described at:
http://icecube.wisc.edu/~dglo/visad-collab/index.html
The IDV supports remote collaboration using VisAD but
without VisAD's built-in support. Perhaps someone from
Unidata can describe how that works.
Note there are complex synchronization problems with
remote collaboration, so if you can use the built-in
support or copy the IDV approach, it will make life
easier.
Good luck,
Bill
p.s., happy new year everyone
