Hi!
I'm trying to use JDBCStore with mySQL under Win98. It looks like Tomcat can
connect to the database I get to see the created process in the Process list
in the WinMySQLadmin-Programm, but no entries are sent to the database.
Instead I get the following Exception:

the other logs seem to be all right.
I've put the following lines in the server.xml as my application context:
<!-- SEP Portal Context -->
<Context path="/Portal.war" docBase="Portal" debug="0"
reloadable="true">
<!-- Manager for mySQL-Database -->
<Manager className="org.apache.catalina.session.PersistentManager"
debug="99"
saveOnRestart="true"
maxActiveSessions="-1"
minIdleSwap="-1"
maxIdleSwap="-1"
maxIdleBackup="-1">

driverName="org.gjt.mm.mysql.Driver"
connectionURL="jdbc:mysql://localhost/tomcatsessions?user=ODBC"

sessionDataCol="data"
sessionValidCol="valid"
sessionMaxInactiveCol="maxinactive"
sessionLastAccessedCol="lastaccess"
checkInterval="60"
debug="99" />
</Manager>
</Context>
After the time specified under checkInterval has passed the tomcat program
window (i.e. MS-Dos Window I get when I start tomcat) displays the following
message:

Any suggestions are greatly appreciated!!!
