Hi Kushal
I have cc'd the user mailing list so that others in the community can
respond when I am not around or if they have better answers.
Please use "Reply All" in your response so that it will reach the
mailing list.
Yes, I had written that sample. For understanding Shoal concepts, look
into my blog entry :
http://blogs.sun.com/shreedhar/entry/shoal_clustering_101 if you have
not done so already. If you have, then please send us your questions and
we will be happy to help.
On the error you are seeing, Can you try executing your sample class as
follows from a terminal window (or a dos command window)? It is quite
possible your Netbeans environment may not have the right library
resolutions.
Assuming you are using Windows
java -cp .;<path-to>\shoal-gms.jar;<path-to>\jxta.jar SimpleShoalGMSSample
with the jars being from the 1.1_08182009 zip file.
I executed the above on my mac after compilation and did not see your
errors. Here's the detailed terminal window output on my mac (I had the
SimpleShoalGMSample.java file on the same directory as the unzipped
Shoal GMS directory :
