Hi Dan,

some thoughts along the line

* Just to make sure - you are running NOT on Windows?
* are you redirecting streams within your Java code and the Bash scripts? If 
so, can you get rid of them? I vaguely remember issues where a process was 
killed by the ExecuteWatchdog but hang on a re-directed stream
* do you have more information regarding the “ExecuteWatchdog” problem - maybe 
some code snippet to reproduce the issues

Thanks in advance,

Siegfried Goeschl

Re: [EXEC] Question

[Dan C]

Thanks for the reply!!

Here’s my situation:
I’m using the Apache Commons Exec version 1.3 code to call a bash script (which 
in turn calls one or more bash scripts).  In most cases, everything works and 
the calling Java code gets a response.  However, on some occasions, the call to 
DefaultExecutor’s execute method never returns (I’m calling one of the 
synchronous execute methods) …

I have tracing in the bash scripts which indicate that they have finished.  
Also, I am using the ExecuteWatchdog class, but it doesn’t recognize the fact 
that my timeout has been exceeded.

So, I’m looking for the following :
 - Some help (tips/tricks/what to look for/at) with how to debug my problem.
 - A good clear example of how to use the Apache Commons Exec for
- a synchronous call to a bash script
- an asynchronous call to a bash script   

Thanks in advance for any help!!

Hi Dan,

You can post the question directly on mailing list. With questions you can
give some references like Github gist or link to github commits url.
