Subject RE: how to use single dbcp resource across multiple webapps
Date Thu, 11 Sep 2003 19:20:14 GMT
You should be able to set up JNDI-based DataSources in the
<GlobalNamingResources> tag at/near the top of your server.xml.  Many recent
posts regarding this with problems using ResourceLinks in the
DefaultContext, but if you're explicitly defining your contexts as it
appears you are, it should work (link global resource in each Context you
want to use it in).

Search archives for more info.

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?
