invoking a call to a window executable fails when request output to file
Hi,
When invoking a call to a window executable it fails(returns 1 instead of 0) when requesting output to file by using "> filename.txt". This nornally works when run directly within a
windows command prompt, and it also works if I don't add the "> filename.txt" at the end. Also instead of outputting to a file I would like the same called executable to output to a memory variable that I can extract data without going to a external text file.
Below is the .java file
package com.insequence.gv;
public class Jinvoker {
public static int invoke(String program) throws java.io.IOException, java.lang.InterruptedException
{
System.out.println("invoking program: " + program);
Process p = Runtime.getRuntime().exec(program);
int exitValue = p.waitFor();
return exitValue;
}
public static void main(String[] argv)
{
try
{
System.out.println("invoker start");
//int retval = invoke("c:\\tvalesky\\java\\invoker\\targetexe arg1 arg2 arg3");
//int retval = invoke("C:\\Program Files\\FWTools1.1.0\\bin\\gdalinfo.exe C:\\data\\EarthData2005\\Ortho\\no_collaged.tif");
String arg1 = "C:\\data\\EarthData2005\\Ortho\\no_collaged.tif > c:\\testing.txt";
//String arg1 = "C:\\data\\EarthData2005\\Ortho\\no_collaged.tif";
int retval = invoke("C:\\Program Files\\FWTools1.1.0\\bin\\gdalinfo.exe " + arg1);
//int retval = invoke("C:\\Program Files\\FWTools1.1.0\\bin\\gdalinfo.exe");
//String arg1 = "-s_srs epsg:26915 -t_srs epsg:4326 C:\\data\\EarthData2005\\Ortho\\no_collaged.tif C:\\data\\EarthData2005\\Ortho\\no_collaged2.tif";
//int retval = invoke("C:\\Program Files\\FWTools1.1.0\\bin\\gdalwarp.exe " + arg1);
//int retval = invoke("C:\\testing.bat C:\\data\\EarthData2005\\Ortho\\no_collaged2.tif");
System.out.println("invoker end: returned " + retval);
}
catch(java.io.IOException e)
{
System.out.println("IOException caught: " + e);
}
catch(java.lang.InterruptedException e)
{
System.out.println("InterruptedException caught: " + e);
}
}
}
Thanks,
