Ben, what is it exactly that you see, does it continue to use a different

Or perhaps it doesnt pick up a table modification?
Hi Johnny,
In one case the database was migrated to a new server. When the WAR with
the new JDBC string included was deployed, the app continued to attempt
to connect to the old server.
Ben I dont think, its something wrong with TC, but I have seen the
behaviour, and it has to do with Deployer and the Dev environment, in
particular Netbeans.
Just check the following is not happening.
When Netbeans runs a War in dev environment, it takes control of TC, and
does not install the WAR in Tomcat, it tells TC to use the Build folder.
If you then drop a WAR in, NB does not let go, but the WAR appears to run,
however its still using the DEV base files.
If you have been testing from the dev environment, its a good habit to
delete the conf/Catalina/host/webappcontext.xml, then drop the WAR in, or if
you get the funny again, have a look at it and it will show you which base
is running, I'm guessing its still the connected to the DEV base.
Its not really a bug, its two deployers battling for ownership of the
context path.
In another case, the min and max connection pooling settings were
increased, but did not take affect.
Both cases were related to the JDBC connection settings, rather than a
table on the database.
Cheers, Ben
