RE: [smila-user] SMILA/ OSGi at Linux

[<Juergen.Schumacher@xxxxxxxxxxx>]

To me, it looks like nohup (or the &?) invalidates the standard input of SMILA so that the OSGi console cannot read it anymore.

On my Linux system it's different: with "nohup ./SMILA &", nohup.out first contains only a "osgi>" and nothing happens,

until I use "fg" to get the process back to foreground, then I get this exception, but it SMILA seems to work.

Without the "&" (just "nohup  ./SMILA"), it starts immediately without any stacktrace in nohup.out. If I push it into

background then using ctrl-z and bg, it hangs completely until I get it to foreground again, and then the same

stacktrace as above is printed. Strange, isn't it?

 

Any Unix guru here? (-;

 

Cheers,

Juergen.

Hi Jürgen,

 

es ist sogar noch lustiger:

 

nohup ./SMILA &

Könnte daran liegen, dass beim start via nohup Verzeichnisse nicht passen !?

Hi Andreas,

 

I did not yet find an out-of-the-box solution. There is something here that might help:

 

http://willcode4beer.com/ware.jsp?set=equinoxBootstrap

 

(Nice domain name ;-). But I think we would have to adapt this to SMILA.

Or does anyone else a simpler idea?

 

Cheers,

Juergen.

Hi,

 

could somebody please give me a hint how to close (close command at OSGi-console) a running background (startet with nohup or screen) SMILA at Linux OS?

 

Many Thanks
