Dear all,
	I don't know which group I should post my problem. Sorry, if I was wrong.
	I write a Java servlet run on Jigsaw which use JDBC connect to mysql server
. I use a com.mm.mysql driver to connect the sql server.
	When my servlet connect(getConnection()), Jigsaw return error message like 
this :
============================================================================

	I try to check which wrong.
	So, I try to use JDBCTest1_03, a test suit from Sun. Its work well. No prob
lem to connect to mysql with the same url,user and password.
	I think, it is a problem of the password, because I don't know, if the user
 has no password, how I call the getConnection().

bye,
