db에서 유저는 다음과 같이 되었구요

mysql> select user,host,password from user where user='nmail';
+-------+-----------+-------------------------------------------+
| user | host | password |
+-------+-----------+-------------------------------------------+
| nmail | 127.0.0.1 | *56E0317CB5E9C614E67598EDE3DA56495544D54B |
| nmail | localhost | *56E0317CB5E9C614E67598EDE3DA56495544D54B |
+-------+-----------+-------------------------------------------+
2 rows in set (0.00 sec)

톰켓 db세팅은

drivers=org.gjt.mm.mysql.Driver
logfile=/usr/local/jakarta-tomcat-3.2.3/logs/pool.log

/ mydb - Nmail DB
mydb.url=jdbc:mysql://127.0.0.1:3306/nmail?useUnicode=true&characterEncoding=euc-kr
mydb.maxconn=10
mydb.user=nmail
mydb.password=nmail

/ mydb2 - External member DB (사용하지 않을경우엔 mydb와 동일한 정보를 넣으십시오.)
mydb2.url=jdbc:mysql://127.0.0.1:3306/nmail?useUnicode=true&characterEncoding=euc-kr
mydb2.maxconn=10
mydb2.user=nmail
mydb2.password=nmail

글구, 로그 마지막 부분은.
