Using a JNDI datasource created by another application with Tomcat

Question

I have a .properties file in my application which contains dataSource properties. I set up a JNDI reference to this dataSource using the following code :

//          


        

Answer 1

Actually, it is possible to access others JNDI resources, if the servlet implements org.apache.catalina.ContainerServlet. This interface has a org.apache.catalina.Wrapper attribute, that is "populated" by the container itself.

through that, I created a simple application to monitor resources.

BUT, I would like to do that in a listener, so my resource monitor could start when the container starts. Anyone knows a way?
