Subject RE: [DBCP]: Tomcat+MySQL. Intermitent DbcpException: Server configuration denies access to data source
Date Tue, 26 Aug 2003 10:07:30 GMT
Hello!

I'm not sure I understand what you mean. I have finally statements that
assure that my result sets, statements and connections are close.
Are you suggesting a way I can check they are actually properly closed
using the JDBC connection pool API?
