I need a good example of a JNDI lookup for an oracle database. This is the code I have for getting the datasource however I still need to create the InitialContext. What do I put into the env hashtable?
By failing to prepare, you are preparing to fail.<br />Benjamin Franklin (1706 - 1790)
In JBoss, the DataSource definition is deployed as a *-ds.xml file in the server's deploy directory.
Are you trying to do this lookup from client code, or from within an application deployed on the server?

From an application deployed on the server. It looks as though I have the JNDI names bound to the database. I know this because when JBoss comes up, it shows that in the console log. BUT when I do a lookup on the names it returns an exceptiom and gives me this.
When I step through the code and into the InitialContext class.. it fails on this method...
Specifically this line...
which in turn goes here..
environment is equal to an empty hashtable w/no key/value pairs in it and so answer is equal to null and thus returns null. And thus throws an exception. Specifically it throws this exception...

You need to specify the naming factory you are using. For JBoss4 that will be java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory. You'll also need the to include the URL for the naming provider, probably java.naming.provider.url=jnp://localhost:1099.
However, if you need to specify these environment values this suggest you are trying to lookup the DataSource from a remote client. If you are be aware this is only possible from JBoss4 and you need to configure your DataSource to allow this with <use-java-context>false</use-java-context> in the DS file.
