Subject Re: Problem w/ 2 jdbc DataSources
Date Sat, 22 Feb 2003 03:50:39 GMT
Solved it.  Pretty embarrassing.  The
org.apache.commons.dbcp.BasicDataSourceFactory class has a setter for
"validationQuery", so I have an  entry in server.xml for that.  I mindlessly
set a SELECT on an empty table, so the loop was repeated attempts to
validate the query.  It's always like that, isn't it?
