RE: Transactions in client code

[David Elliott]

Hi Robert,

re: UserTransaction, you'll have to wait for a wiser soul that I on that
one.

re: Listing objects bound to a context, I will reprint here the good bits
that I've read and tried successfully from the discussion starting on page
154 of 
the O'Reilly Java Enterprise in a Nutshell (which I highly recommend).

Context c = new InitialContext();
NamingEnumeration enum = c.list("");
while (enum.hasMore()) {
        NameClassPair ncPair = (NameClassPair) enum.next();
        System.out.println("JNDI name: " + ncPair.getName() + " of type " +
ncPair.getClassName());
}

Cheers,

Dave Elliot

This never works on my setup. Maybe I'm doing wrong. If I try, as suggested
below I get this exception:

javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an
application resource file:  java.naming.factory.initial

Then if I try my usual initialContext instantiation (which works for ALL
other JNDI lookups)

        Properties env = System.getProperties();
        env.put("java.naming.factory.initial",
"com.evermind.server.rmi.RMIInitialContextFactory");
        env.put("java.naming.provider.url", "ormi://localhost/damanPay");
        env.put("java.naming.security.principal", "admin");
        env.put("java.naming.security.credentials", "123");
        initCtx = new InitialContext(env);

I get the following

javax.naming.NameNotFoundException: java:comp/UserTransaction not found

I've seen lots of postings on this mailing list about getting a
UserTransaction instance into the client, and of those few that have had
replies, none seem to work.


Anyone else experience this?

Regards
Robert Hargreaves

PS Also does anyone know of a class or utility that gives you a list of
names bound to a particular JNDI context?
