XML:DB Excption occured 1

[HuYing]

I have two testing servers, both with xindice db server installed.
I've already added a document into collection /db/addressbook, There is no
problem to run Example1 on both my testing servers locally.

When I was trying to query remote document with modified
org.apache.xindice.examples.Example1, I  got XML:DB Exception occured 1

 Here is the code I've modified :
 col =
            DatabaseManager.getCollection
("xmldb:xindice://192.168.0.2:4080/db/addressbook");

I am running this application on server 192.168.0.3

I can telnet 192.168.0.2 4080  and 192.168.0.3 4080, both servers are
running

I don't know what is wrong.

Any help would be highly appreciated.

Thanks

Ying
