[xmlblaster] JdbcQueuePlugin won't load

[Michael Atighetchi <matighet at bbn.com>]

I have a xmlblaster scenario with 2 clients that communicate with
eatch other via talking to a xmlblaster slave instance (which in turn
talks to a master).

I'd like to change the master so that it stores messages in a mysql
database instead of keeping them in RAM. First, I changed the qos key
on publishing messages to "<qos> <persistent /> </qos>". I also added the
following line to the xmlblaster.properties file of the master:

ProtocolPlugin[JDBC][1.0]=org.xmlBlaster.protocol.jdbc.JdbcDriver
CbProtocolPlugin[JDBC][1.0]=org.xmlBlaster.protocol.jdbc.CallbackJdbcDriver
QueuePlugin[JDBC][1.0]=org.xmlBlaster.util.queue.jdbc.JdbcQueuePlugin
JdbcDriver.drivers=org.gjt.mm.mysql.Driver
queue.persistent.url=<...>
queue.persistent.user=<...>
queue.persistent.password=<...>
cb.queue.persistent.url=<...>
cb.queue.persistent.user=<...>
cb.queue.persistent.password=<...>

cb.queue.persistent.connectionPoolSize=3
cb.queue.persistent.connectionBusyTimeout=90000
cb.queue.persistent.maxWaitingThreads=300
cb.queue.defaultPlugin=RAM,1.0
cb.queue.persistent.tablePrefix=xmlBlaster
cb.queue.persistent.tableAllocationIncrement=2

NOTE: assume reasonable entries for <...>


Upon starting up the master node, I see that the JdbcDriver
initializes correctly:
[Feb 25, 2003 6:31:08 PM INFO  JdbcDriver-/node/psq1] Started successfully JDBC driver with loginName=__sys__jdbc

However, I don't see any printout for the JdbcQueuePlugin, but lots of
printout for RamQueuePlugin.

Upon starting up the clients, messages are still kept in RAM in the
master, and not put into the mysql database.

How can I change the configuration to use jdbc for storing messages ?
