Hi,
Sorry, my bad, I got already caught last time, it is CLASSPATH_XTRA not
XTRA_CLASSPATH.
You can double-check in your controller startup script what the exact
environment variable name is.
Sorry for the confusion,
Emmanuel

Hi,
I configured the env variable XTRA_CLASSPATH as you said on both the
controllers, logged out and logged in. Checked whether the variable is
properly set, cleaned up the transaction db, and restarted both the
controller afresh. But I still get the following error on both the
controllers.
Should I add
XTRA_CLASSPATH=$SEQUOIA_HOME\drivers\mysql-connector-5.1.6.jar
to my environment variables list ?
Yes, on both controllers.
Right now those jars are only loaded in specific classloaders
to access
the database but they are not visible to the rest of the controller
classes or the group communication libraries, hence the
NoClassFoundException when sending back the error.
Here is the configurations again for your reference
Sequoia version : 2.10.10
MySQL DB: 5.1
MySQL Driver: 5.1.6
Java version: 1.6.0_4
