I've been banging my head against this one for a couple days now, hope folks
can help me out.
I have an application I'm developing for a client. We've been developing it on
localized machines for a while now, using all intra-net based services (jboss
et al are all on the local machine). The app consists of a series of
sessionbeans sitting in a deployed app in JBoss, accessed from a desktop Swing
app via RMI.
Locally, everything works fine. The jndi lookups work, I can get to the
appserver without any problems. While in the end, the app will be installed in
an intranet environment, I'd like my client to be able to run the Swing client
remotely to test things out. I've deployed the Swing client app as a
JNLP-enabled JAR file, and the users can download and run it, but I do not want
to open up sockets through the firewall to the appserver (which is on a machine
at a colo facility).
What I'd like to do is either use direct socket-forwards in SSH, or use the
SOCKS function (-D) to allow the remote Swing client access to the JNDI server
and beans on the jboss server.
I haven't found a real way to do this yet. My jndi.properties file states:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
| java.naming.provider.url=jnp://127.0.0.1:1099
So it would make sense that I could just use an ssh port forwarder to access
the JNDI server:
ssh -L1099:127.0.0.1:1099 my.remote.host
Alas, that doesn't seem to work. When I run this, I get an exception on the
InitialContext.lookup() call:
[java] *** Exception thrown in com.arete.JQuo.AppsBrowse.connectUp() ...
| [java] *** javax.naming.CommunicationException [Root exception is
java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested
exception is:
| [java] java.net.ConnectException: Connection refused]
| [java] javax.naming.CommunicationException [Root exception is
java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested
exception is:
| [java] java.net.ConnectException: Connection refused]
| [java] at
org.jnp.interfaces.NamingContext.lookup(NamingContext.java:707)
Perversely, I still see a socket connect in ssh, so -something- is happening,
why am I getting a Connection refused error?
My ultimate goal is to use either a SOCKS remote proxy to get across the
firewall to the JBoss server, or set up fixed sockets. I'll be happy with
EITHER answer, this is not for production / final release, it's just so the
client can see the work I'm doing.
The code being used to connect is:
System.out.println("Getting initial context...");
| Context c = new InitialContext();
| System.out.println("Looking up appmanager...");
| Object o = c.lookup ("AppManager");
| System.out.println("Back from lookup()...");
I never see the last message - the exception is thrown on c.lookup().
Help please?
