With TomcatJNDI you can access every JNDI resource you configured within Tomcat as used to do in your web application. The code to achieve it is simple and looks like

TomcatJNDI tomcatJNDI = new TomcatJNDI();
tomcatJNDI.processContextXml(contextXmlFile);
tomcatJNDI.start();

DataSource ds = (DataSource) InitialContext.doLookup("java:comp/env/path/to/datasource")
