Re: [ptp-dev] Question about running additional commands in external tools framework
|
Greg
I got the PTP case working using this information. Thinking about this
now, I'm not sure there is a serial case to deal with since the only way
that I know remote applications get invoked now in Eclipse is thru PTP and
one of the PTP resource managers. Are there ways to invoke serial apps
remotely that I'm missing?

Re: [ptp-dev] Question about running additional commands in external tools
framework
Dave,
Here's what you need to do to get the hostname from a resource
manager. In the case of a serial connection, it will depend on how
you've implemented the connection. If you're using RSE then you'll
need to explore the gory details of RSE to find it. You might find
some useful code in the org.eclipse.ptp.remote.rse.core plugin.
Cheers,
Greg
1. First, get the resource manager configuration from the resource
manager:
IResourceManagerConfiguration rmConfig = rm.getConfiguration();
2. Check that the resource manager configuration is derived from an
AbstractRemoteResouceManagerConfiguration:
if (rmConfig instanceof AbstractRemoteResourceManagerConfiguration) {
...
}
3. If it is, use the remote services ID to get the remote services
used by this RM:
AbstractRemoteResourceManagerConfiguration remoteRMConfig =
(AbstractRemoteResourceManagerConfiguration)rmConfig;
IRemoteServices remoteServices =
PTPRemoteCorePlugin
.getRemoteServices(remoteRMConfig.getRemoteServicesId());
4. Then use the remote services to get the remote connection:
IRemoteConnection connection =
remoteServices
.getConnectionManager
().getConnection(remoteRMConfig.getConnectionName());
5. Finally, use the IRemoteConnection to get the remote address:
String address = connection.getAddress();
