How to run a java program using ProcessBuilder in high priority?

Question

I am using a batch file to invoke a GUI. This GUI has a button (B1) that on click invokes a copy of itself. Now I want to increase the priority of the GUI whether it's run from the batch or button B1.

With batch, I am able to increase it's priority but not with B1.

The following code executes on click of button B1: (I am using cmd to increase the priority; I don't know if there is any other way)

final ProcessBuilder processBuilder = new ProcessBuilder("cmd", 
  " /C", 
  " start /high", 
  path,
  "-DTESTKERNEL_PROPERTIES=" + tempFile.getCanonicalPath(),
  "-Djava.util.logging.config.file=" + loggingFile,
  "-Djava.library.path=" + libraryPath,
  "-cp",
  classpath,
  "com.abc.cde.gui.typetwo.GuiTypeTwo");
processBuilder.directory(new File(System.getProperty("user.dir")));

DTESTKERNEL_PROPERTIES is a properties file and is required for the execution of code.

This is the output as list:

cmd, 
/C, 
start, 
/high, 
D:\jdk\jre\bin\javaw,

Remove the spaces before /C and start and split "start /high" into two separate parameters:

new ProcessBuilder("cmd", "/C", "start", "/high", ...)

It says "windows can not find -DTESTKERNEL_PROPERTIES=" i cross checked and found that the file is present at the desired location

Adam Michalik Over a year ago

What is the value of path? Can you first put all process arguments in a list, print it, post the output in your original question and then invoke new ProcessBuilder(list)? There must be some typo or other minor issue there.

The arguments have proper values, i tried to use the list instead. Gives the same result. "Windows cannot find......."

Devil_Queen Over a year ago

Please help anyone. Am really stuck here!

Well, I asked you some questions that you didn't answer (you only said that "the arguments have proper values" - if they did, there wouldn't be a problem), so without more insight there's not much that can be done. Please put all arguments in a list and post the toString() of that list here.
