Oops, you're right that line would not have compiled...I meant I use this:
DataSource ds = (DataSource) new
InitialContext().lookup(application.getInitParameter("db.jndi.dsn"));
...to get a datasource values and assumed the similar line would work for retrieving a
String:
String str = (String) new
InitialContext().lookup(application.getInitParameter("myString"));
...but no dice.
God, why does it have to be so difficult to do something so simple. I love Java for a
lot of reasons, but this kinda stuff makes me really curse it at times. Ok, so you're
saying go and read JNDI documentation and hopefully once I understand JNDI inside and
out I can finally set a freaking application constant paramter?

You're missing a lot. You should read the Servlet Specification,
specially the section on context parameters (context-param elements in
web.xml), which is what you will probably use for simple strings.
You should read the JNDI documentation for what a context (including
InitialContext) is. It doesn't have a getAttribute method, so I
seriously doubt this line of code even compiles, much less works for
datasources or any other type of JNDI resource. You could use a JNDI
context for simple strings, but that's usually overkill.
