jboss seam project deploy error

[myfuture1]

testing a example,the env is:
db: sql server 2000
os:windows 2003
jboss as:jboss-4.2.2.GA

deploy the project and start jboss as,
show the error info:

2007-12-18 17:51:17,843 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Throwable while attempting to get a new connection: null
org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Failed to register driver for: com.microsoft.sqlserver.jdbc.SQLServerDriver; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: com.microsoft.sqlserver.jdbc.SQLServerDriver))

i have copy the sql server jdbc driver to $JBOSS_HOME/server/default/deploy/lib directory

how to solve it

[norman.richards]

Did you restart JBoss after copying the driver over? JBoss does not hotdeploy from the lib directory.

[myfuture1]

sure,i have restarted jboss

but the jboss AS still cann't find the com.microsoft.sqlserver.jdbc.SQLServerDriver class

what's wrong?

[jbalunas]

try the $JBOSS_HOME/server/default/lib directory.

I don't remember there even being a $JBOSS_HOME/server/default/deploy/lib directory.

[myfuture1]

sorry,i made a mistake,there isn't exist $JBOSS_HOME/server/default/deploy/lib directory;

it should be $JBOSS_HOME/server/default/lib directory;


i am sure that i copyed the sqlserver jdbc driver to $JBOSS_HOME/server/default/lib directory;
then get the error info;

what should i do?
