Web Logic 6.1 JDBC Pooling with the Oracle Thin Driver

Question

Hi,
We're slowly getting through a WebLogic 4.5.1 to 6.1 conversion for a small application
at my company. Initially, we had trouble getting the Oracle thin driver working.
We've finally cracked this nut. Now we're trying to get pooling working, and
cannot find an example of doing this with the Oracle thin driver.
Would anyone be able to provide:
1. the portion of the config.xml that pertains to building a connection pool using
the Oracle thin driver
2. the two lines of code for loading the driver and getting a connection from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Thanks very much!

You don't usually edit the config.xml unless it is absolutely necessar. Instead,
you can config the pool in the GUI admin console, quite easily. After you successfully
configed the pool in the console, it is written into the config.xml file for you.
Only thing special when config the pool is the name of the driver and the url.
url: jdbc:oracle:thin@dbhost:dbport:dbinstance
driver: oracle.jdbc.driver.OracleDriver
If you prefer, you can also config the pool from the command line. It is detailed
in the "Weblogic Server Command-line Interface Reference".
2. the two lines of code for loading the driver and getting a connection
from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Again, you don't use the connection directly. Instead, you use "Data Source".
Data source in weblogic is just a connection object factory associated with a
JNDI name. You can therefore lookup the data source with the JNDI name and from
the data source object, you get the connectin object. No need to explicitly load
the driver class.
There are plenty of example codes available in the weblogic examples installed
with 6.1, that uses the data source.
