First of all, thanks a lot for your replies Marc!
I have progressed a little bit in my understanding, and I think I managed to get a working system, so I want to describe to you what I have done. If experts are around they could may be comment on the procedure.
Starting from the beginning:
- I need to access a JBOSS 4.2.0GA stateless session bean from a remote
- my client being behind a firewall I decided to pass my invocations via http, but I need to be sure that is http only !
Reading forums + doc I have done the following changes to a standard jboss installation (on a "server" machine).
1) I have added servlet-invoker.war from the jboss remoting 2.0 package (copy the war in deploy dir), performing the following modification in the config file WEB-INF/web.xml:
| <description>The servlet server invoker locator url</description>
2) I have added a Connector using a xxx-service.xml file that I have created and put in /server/default/deploy
| <mbean code="org.jboss.remoting.transport.Connector"
| display-name="Servlet transport Connector">
| <attribute name="InvokerLocator">
| <attribute name="Configuration">
| <handler subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler>
Now I start jboss running with option -b :
| run.sh -b myhost.domain.name
I think this is important in order to associate the hostname to the variable jboss.bind.address, so to avoid ip number substitutions that would have a bad effect on the firewall....
3) I have installed on the same jboss-server machine a Squid proxy server, configured to listen to port 3128 with the appropriate acl (see Squid documentation)
4) I have forwarded the 3128 port into localhost 13128 using ssh tunneling (-L options)
5) now I can for example access the JMX console if I configure in my web browser the proxy server to be localhost 13128
6) I run the client program using in java command line the options:
| java -Dhttp.proxyHost=localhost -Dhttp.proxyPort=13128 xxxx
and it works !
Now my question is :
Could I avoid to use an external proxy server ?
