Error while running curl command through java

Question

I am trying to run the following curl command through java.This runs properly from the command line, but throws error when i run it using java

curl -XPOST -H'Content-type: application/json' "http://localhost:8084/druid/v2/?pretty" -d'{"queryType":"timeBoundary","dataSource":"wikipedia"}'

This is the java code using processbuilder:

ProcessBuilder pb1 = new ProcessBuilder(
            "-XPOST",
            "-H", "Content-Type:application/json",
            "http://localhost:8084/druid/v2/?pretty",
            "-d", "{\"queryType\":\"timeBoundary\",\"dataSource\":\"wikipedia\"}"

        );

Process shell = pb1.start();

This is the error i am getting.

Exception in thread "main" java.io.IOException: Cannot run program "-XPOST": error=2, No such file or directory
at java.lang.ProcessBuilder.start(ProcessBuilder.java:1047)
at com.druid.DruidConnection.main(DruidConnection.java:69)

You need to have a space between X and POST. The same applies to other options as well — TheLostMind

You need to add curl.exe as a 1st parameter:

ProcessBuilder pb1 = new ProcessBuilder(
            "curl.exe",
            "-XPOST",
            "-H", "Content-Type:application/json",
            "http://localhost:8084/druid/v2/?pretty",
            "-d", "{\"queryType\":\"timeBoundary\",\"dataSource\":\"wikipedia\"}"

        );

Also you need to be sure that folder with curl.exe is in your PATH

PS. Of course it is for Windows, for *NIX just "curl"
