Programatically creating a telnet connection? [message #34767]

Hi,

I'd like to programmatically create a telnet session, supplying the host
and port as parameters, which opens in a Terminal view.

I've read a previous post (sorry couldn't figure how to reply to that
thread):

Programatically creating a connection?
http://dev.eclipse.org/newslists/news.eclipse.dsdp.tm/msg002 29.html

and followed the bug:

Need API to programmatically open the terminal for a specified connection
https://bugs.eclipse.org/bugs/show_bug.cgi?id=185348

I've downloaded TM-terminal-3.0.3.zip and studied the
org.eclipse.tm.terminal, but am now totally confused as to the API I
should use to proceed.

Please can anyone provide a short snippet of how I could get started with
this.

Also I'm confused about the version numbering of org.eclipse.tm.terminal -
as I said I downloaded (from
http://download.eclipse.org/dsdp/tm/downloads/drops/R-3.0.3- 200902181300/)
TM-terminal-3.0.3.zip, but this expands to plugins with versions starting
"2" (eg: org.eclipse.tm.terminal_2.0.3.v200902181600.jar).

Any help gratefully received.

Cheers john

Hello John,

Right now there is no official API for programmatically creating a
connection. You can do it today through internal non-API with this snippet:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=185348#c16
https://bugs.eclipse.org/bugs/show_bug.cgi?id=185348#c19

With respect to version numbering, the bundle versions are almost always
different than the product versions since they evolve based on different
rules ("technical versions" vs. "market version").

http://wiki.eclipse.org/Version_Numbering

In short, a bundle version is only incremented if that bundle changes.
The version of the entire TM/RSE product, however, is incremented on
every release. That's why after some time, the versions differ.

Hi Martin,

thanks for your reply.

I've adapted the code snippet to my needs, simply replacing Ssh with
Telnet, thus:

/*
* Adapted from the following bug:
* [terminal][api] Need API to programmatically open the terminal for a
specified connection
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=185348#c16
*/
private void startTelnetSession(String host, String networkPort) {

ITerminalConnector conn =
TerminalConnectorExtension.makeTerminalConnector(
"org.eclipse.tm.internal.terminal.telnet.TelnetConnector");
if(conn != null) {
//force instantiating the real connector
conn.makeSettingsPage();
TelnetConnector telnetc =
(TelnetConnector)conn.getAdapter(TelnetConnector.class);
if (telnetc != null) {
TelnetSettings settings = (TelnetSettings)
telnetc.getTelnetSettings();
settings.setHost(host);
settings.setNetworkPort(networkPort);
terminal.setConnector(conn);
conn.connect();
}
}
}

... but get compilation errors on the last two lines. I've a couple of
questions:

1) what is the definition of terminal?

2) In my ITerminalConnector
(org.eclipse.tm.terminal_2.0.3.v200902181600.jar) connect has a different
defintion:

void connect(ITerminalControl control);

Thanks for any help.

cheers john

Hi John,

the definition of "terminal" comes from this code:
http://dev.eclipse.org/newslists/news.eclipse.dsdp.tm/msg002 29.html
which is referenced here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=185348#c4

instead of conn.connect() I think you need
terminal.connectTerminal();

Cheers,
