Subject RE: how to use single dbcp resource across multiple webapps
Date Thu, 11 Sep 2003 19:41:05 GMT

I just went through this exercise today.
(See msgs with subject = "java.sql.SQLException: Cannot load JDBC driver
class 'null'")
I do not know why it does not work when set up in the global context(Tomcat
admin puts datasources here).  Let us know if you get an answer.

Subject: how to use single dbcp resource across multiple webapps


i setup dbcp according to Tomcat docs successfully for one web app, but when
tried to use resource (defined in server.xml) in second web app (with
appropriate WEB-INF/web.xml), get the following:

java.sql.SQLException: Cannot load JDBC driver class 'null'

meanwhile, dbcp resource works fine with first app.
i figure it is because the resource is defined within following context,
where path specifies first web app:

<Context path="/epl" docBase="epl" debug="5" reloadable="true"

do i need to define a second context and dbcp resource, or is there some way
to use a single dbcp resource across contexts/web-apps?
