Getting hibername / database setup

I'm trying to run the CVS version and having trouble

Running the createdb task yields a stack trace ending in:
Error creating schema Could not find datasource: Can't find 
SerialContextProvider
     [java] net.sf.hibernate.HibernateException: Could not find 
datasource: Can't find SerialContextProvider
     [java]     at 
net.sf.hibernate.tool.hbm2ddl.SchemaExport.execute(SchemaExport.java:155)
     [java]     at 
net.sf.hibernate.tool.hbm2ddl.SchemaExport.main(SchemaExport.java:284)

And plowing ahead by running the ant-built war gives me this:

java.lang.NullPointerException
	at org.jlcp.infrastructure.persistence.hibernate.web.HibernateSessionFilter.doFilter(HibernateSessionFilter.java:65)
	at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:213)
	at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193)

	at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:643)
	at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480)

I assume there is some file somewhere that I have to setup to tell it about the database I would like to use.

I would like to use the simplest database for now, mckoi is fine, but I do not see the jar in the
webapps/WebINF dir.  I also have mySQL running if needed.

Thanks,
