Subject Re: creating tables and dynamic configiration

Dmitry,

you can still use the ThreadLocal strategy without the connection pool
stuff. In a client side app i am assuming you would only need one
connection. So, you could write your own datasource factory that
implements the DataSourceFactory interface and your own DataSource
which implements the DataSource interface. Then you could configure it
in a  JDBC transaction manager in your sqlMapConfig.xml files.

---- example config ----
  <transactionManager type="JDBC" >
    <dataSource type="my.custom.datasourcefactory.MyClass">
      <property name="Username" value="${driver}"/>
      <property name="Password" value="1"/>
    </dataSource>
  </transactionManager>
