Hey VP, thanks for replyng.
I have read the codes from a book and havesome code for client. The server side is yet to be done....but I have problems in compiling them as I am Unable to import javax.xml.soap.*;
This is basically a request to the Server asking it to find the match of the word "Mickey" from the XMLfile at the server...JAXRPC is involved(I Presume:) There are some supporting files.........hey But it doesn't compile only here. Hope it does in yrs
