I would look at how borland enterprise server initialises and utilises JDBC
2.0 connections in a webapp agnostic manner referenced by JNDI at
http://www.borland.com/resources/en/pdf/white_papers/bes_a_guide_to_porting_applications.pdf
(You will note that other AppServers such as WL bind their JDBC 2.0
connections to specific web applications with target= )
Anyone else?

We have been relying on Turbine for all database connections and
pooling..Hence we wouldl like to stick to that.

The jar is made available to both the applications:
WebApplication1 - WEB-INF/lib/dbconnection.jar
WebApplication2 - WEB-INF/lib/dbconnection.jar
Tomcat is started:
WebApplication1 servlet init() is called , which inturn makes a call
to the Initialise turbine
WebApplication2 servlet init() is called , which inturn makes a call
to the Initialise turbine(again!!!!)
Now, When a connection is made to the DB by WebApplication1 , it will
get a connection from the connection pool created by WebApplication1
and When a connection is made to the DB by WebApplication2 , it will
get a
connection from the connection pool created by WebApplication2
Problem:
Since both the applications are connecting to the same DB, I would
like to have both the applications served with connections from the same
pool.
How can I implement this in the scenario presented above?
P.S : The Struts factor in the above problem is that both my web
applications are struts based :))
What about removing the dbconnection.jar from the WEB-INF/lib and putting
it into the %TOMCAT_HOME%/common/lib directory ?
There it will be found from both WebApps using the same classloader...
static Blocks will then only be executed once (IMHO).
Kind regards,
Thomas
Alternatively, you could configure a datasource in Tomcat and have both
web
apps look it up, instead of having each app setup its own database
connections.
