Run batch file from Java code

Question

I am trying to run a batch file that is in another directory from my Java executable  I have the following code        try           Process p    Runtime getRuntime   exec  cmd  c start   C   Program Files  salesforce com  Data Loader  cliq process  upsert  upsert bat                        catch  IOException ex            The result is that the program opens a cmd window in the root directory where the program was run at and doesn t access the file path I provided

Your code is fine  but the problem is inside the batch file   You have to show the content of the bat file  your problem is in the paths inside the bat file

Rather than Runtime exec String command   you need to use the exec String command  String   envp  File dir  method signature   Process p    Runtime getRuntime   exec  cmd  c upsert bat   null  new File  C   Program Files  salesforce com  Data Loader  cliq process  upsert       But personally  I d use ProcessBuilder instead  which is a little more verbose but much easier to use and debug than Runtime exec     ProcessBuilder pb   new ProcessBuilder  cmd     c    upsert bat    File dir   new File  C  Program Files salesforce com Data Loader cliq process upsert    pb directory dir   Process p   pb start
