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.
