Configuring Fiddler

The configuration passed to Fiddler will be passed to one or more of the configurable classes listed below. Thus, the same configuration used to configure Fiddler is also used to configure instances of the classes used by Fiddler to perform that service's lookup discovery and join management duties. For information on the configuration entries supported by those classes, refer to the documentation associated with each class.

If you choose to use the HTTP server supplied with the Apache River release, then the following command will start that daemon in verbose mode, listening for requests on port 8080, and serving files from the root directory, jini_install_dir/lib-dl:

java_install_dir/bin/java -jar jini_install_dir/lib/classserver.jar \
                               -dir jini_install_dir/lib-dl \
                               -port 8080 \
                               -verbose

• transient (not persistent and not activatable)
• nonactivatable (persistent but not activatable)
• activatable (persistent and activatable)

One of the significant features of Jini Network Technology is that it is designed to allow for configuration and pluggability of the remote communication framework itself, as well as the transport employed by that framework. Because of this, the list of framework/transport combinations that Fiddler can be configured to use for its remote communication, in conjunction with the mode in which Fiddler is configured to run, is essentially boundless. The flexibility inherent in the configuration mechanism allows Fiddler not only to be configured to employ any existing remote communication framework and transport, but also any future framework or transport that may be defined. The current release of Apache River provides implementations for the following remote communication frameworks and transports:

• JRMP over TCP/IP
• Jini Extensible Remote Invocation (Jini ERI) over TCP/IP (the default for all modes)
• Jini ERI over HTTP
• Jini ERI over HTTPS
• Jini ERI over SSL/TLS (JSSE)
• Jini ERI over Kerberos/GSS-API (JGSS)

So as not to exceed the scope of this document, the examples below are limited to the following combinations of mode and remote communication mechanism:

The reason the restarted service cannot be re-exported with the object ID from its previous run is that when a service is configured to use JRMP, the service is exported using a {@link net.jini.jrmp.JrmpExporter}, and such an exporter cannot be created with a pre-specified object ID. Thus, although the old object ID could be recovered from persisted state when the service is restarted, there is no way to re-export the service (under JRMP) with that old object ID. And so a new object ID is assigned to the service's inner proxy every time the service is restarted. To address this, one might argue that clients could always obtain a new service proxy (containing the new inner proxy with the new object ID) simply by re-querying the lookup service. But this only addresses primary proxies to the service; it doesn't address secondary proxies such as leases the service had issued to its clients on previous runs. Any such leases would no longer be valid, and so each client would need to re-register with the restarted service through the new primary proxy to obtain new leases. From the point of view of the client then, it would be as if the service was started anew.

The second command will destroy the shared VM in which Fiddler (and possibly other services) are running. That command will remove the shared VM log directories, but will not remove any service-specific persistence directories. Typically, this command is executed only after all services executing in the shared VM have been gracefully (administratively) shutdown.

The second command will destroy the shared VM in which Fiddler (and possibly other services) are running. That command will remove the shared VM log directories, but will not remove any service-specific persistence directories. Typically, this command is executed only after all services executing in the shared VM have been gracefully (administratively) shutdown.
