I don't follow you -- shouldn't I be able to create an instance of a naming
context and populate it from within my App, then refer back to it? For this
app, I don't mind hard coding the parameters, it's just that I have a class
called DataStore that contains all the access points to the persistence
layer of my web app. The DataStore class knows nothing about Tomcat.
Surely I can use some other JNDI provider and "fool" the DataStore class
into talking to it... In fact, here is the single point of reference to the
database resource:
// Return DataSource via JNDI with object named in
Constants.DATABASE_KEY
public static javax.sql.DataSource getDs() throws java.sql.SQLException
{
javax.sql.DataSource ds = null;
try {
// Obtain our environment naming context
javax.naming.Context initCtx = new
javax.naming.InitialContext();
javax.naming.Context envCtx = (javax.naming.Context)
initCtx.lookup("java:comp/env");
// Look up our data source
String check = Constants.DATABASE_KEY;
ds = (javax.sql.DataSource)
envCtx.lookup(Constants.DATABASE_KEY);
} catch (javax.naming.NamingException e) {
e.printStackTrace();
return null;
}
return ds;
}
What else can I use as a JNDI provider?

Howdy,
Currently tomcat doesn't have an external JNDI provider, so you can't
really do what you're looking for.
