I have defined a JNDI JDBC datasource as a resource in the global context.xml file. I was under the impression that what this does is to create a shared connection pool that is tomcat wide. But in practice what seems to happen is that a new instance of that connection pool is created for each context that is running in the container. For example, if I have 6 web applications deployed I end up with 60 connections to my database, assuming the default initialSize parameter of 10.
Is there a way to have a single connection pool that is shared amongst deployed applications? In case it is relevant this is tomcat 7.0.19 using the tomcat connection pool. Thanks -Dave
