The short answer is that getting JNDI to work is a bit tricky as there are generally lookup dependencies on the context class loader and for some servers the lookup must be done by an incoming request thread. Here's an answer I wrote a ways back that should help but feel free to ask more questions as needed.

I manged to get this to work using the embedded jetty. In this scenario, the standalone application gets some command-line parameters specifying to which database connect and under what port to expose the http-server. This is fine, so I moved a step further and tried to deploy the same code using the servletbridge into some servlet-containers. After some troubles I managed to get this work for tomcat6 and Oracle 10g app-server (10.1.2). For passing the parameters specifying my database, I used the launch.ini in the servletbridge directory to set some environment-variables. But this solution has one mayor drawback: To adapt the jdbc-url I have to edit the launch.ini, make a new .war and deploy this .war on my app-server. Is there a way to do this more conveniently? I'm new to application servers, here is what I tried so far: But how do I get the jdbc-connection from within my eclipse-application? I'm doing the following to get the httpService in my Activator: ServiceReference reference = context.getServiceReference ( HttpService.class.getName()); HttpService httpService = null; if ( reference != null) httpService = ( HttpService) context.getService( reference); To get the db-connection I tried the following code from the tomcat-6 documentation (); http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html ): try { javax.naming.Context initContext = new javax.naming.InitialContext (); javax.naming.Context envContext = (javax.naming.Context)initContext.lookup("java:/comp/env"); javax.sql.DataSource ds = (javax.sql.DataSource)envContext.lookup ("jdbc/myoracle"); java.sql.Connection conn = ds.getConnection(); } catch ( SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch ( NamingException e) { // TODO Auto-generated catch block e.printStackTrace(); } But this didn't work. Tomcat6 complained about "java.lang.ClassNotFoundException: org.apache.naming.java.javaURLContextFactory" and OC4J reported it could not find the java:/comp/env context. Any hints on how to solve this?
