Why not logging the result. Then you will know more:
Process p = Runtime.getRuntime ().exec ( command );
if ( NSLog.debugLoggingAllowedForLevel ( NSLog.DebugLevelDetailed ) )
{
NSLog.out.appendln ( "process waiting " );
}
int terminated = p.waitFor ();
if ( NSLog.debugLoggingAllowedForLevel ( NSLog.DebugLevelDetailed ) )
{
NSLog.out.appendln ( "result: terminated (0=OK) : " + terminated );
BufferedReader in = new BufferedReader( new InputStreamReader ( p.getErrorStream () ) );
NSLog.out.appendln ( "error : " + in.readLine () );
}
This will not work if the process which is being executed has more output or error message than the InputStream or ErrorStreams' buffer from the process. Then p.waitFor() will never return because the process tries to write more output to the input stream but the input stream will be cleared / flushed / read from -after- the waitFor() method returned. Please read my previous post to this thread.
cheers, David
