Re: some basic defination in common exec
2010/3/4 maven apache apachemav...@gmail.com
HI:
I want to use common-exec,however I am confusing with some definations -
which is the arguments in a cmd to be executed:
for example, the cmd I want to execute is :
*gdal_tran HDF:d:\data\hdf5\new\m0729_**v003-127.he5://HDFEOS/GRIDS/**
Amount_O3/Data_Fields/**SolarZenithAngle d:\aa.tif -a_ullr -180 90 180
-90*
The gdal_tran is the command name, all of the later are the parameters
required,
*HDF:d:\data\hdf5\new\m0729_**v003-127.he5://HDFEOS/GRIDS/**
Amount_O3/Data_Fields/**SolarZenithAngle*-- is the organial data
*d:\aa.tif* --- the target file
*-a_ullr -180 90 180 -90*-- the option parameters
So I want to know which parameter can be added using the
commandLine.addArgument() method?
Also I have do a test:
When I run the command without common-exec, the core codes are shown below:
public static void main(String[] args) {
String cmd=gdal_translate
HDF5:\/home/kk/grass/data/4404.he5\://HDFEOS/GRIDS/OMI_Column_Amount_O3/Data_Fields/ColumnAmountO3
/home/kk/4.tif;
Process p1=Runtime.getRuntime().exec(cmd);
InputStream is=p1.getInputStream();
BufferedReader br=new BufferedReader(new InputStreamReader(is));
String line=null;
for(line=br.readLine();line!=null;line=br.readLine()) {
System.out.println(line);
}
--
This code worked well.
Then I tried to build the command with common-exec, the core codes are shown
below:
--
CommandLine line=new CommandLine(gdal_granslate);
line.addArgument(HDF5:\/home/kk/grass/data/4404.he5\://HDFEOS/GRIDS/OMI_Column_Amount_O3/Data_Fields/ColumnAmountO3,false).addArgument(/home/kk/4.tif);
// here no matter I set the handlQuteo true or false , the result are the
same.
DefaultExecutor de=new DefaultExecutor();
de.execute(line); // I skip the try .
--
Here I got a exception with exit value of 2:
-

I wonder it is my fault of building the command line?

I added a similar test to the code base - can you double-check the following snippet?
