如何在Windows命令提示符下增加命令行参数的大小或限制

Question

Hi I have created a JAVA program which uses ProcessBuilder to start command prompt, java passes command with some arguments to the console and then command prompt is responsible to handle the command, everything is working fine until the command line argument is too long. Actually I am using phantomjs as a command and passing multiple urls as a arguments to the command prompt. Eg: Java generated string-

phantomjs download.js --url=http://google.com, http://yahoo.com, http://website.com..................http://demo.com

When I was passing 100's of urls then it works fine but when increases to 1000's of urls then its not working. I know, it happens because of argument buffer size. When I was trying to pass 1000's urls then it exceeds the maximum byte limit of the command line for windows. So there is any other way to pass this value into file or can we increase the limit of command line arguments.

Please give me some solution for this.

Why not just passing a filename as argument ? The target file contains the list of urls (JSON.stringify or simply one per line)

For example

var system = require('system');
var fs = require('fs');
var args = system.args;

if (args.length === 1) {
  console.log('download.js <filename>');
  phantom.exit(1);
} else {
    var filename = args[1];
    var stream = fs.open(filename, 'r') 

    var line;
    while(line=stream.readLine()) {
        //do want you want here
        console.log(line);
    }

    phantom.exit(0);
}

Run with

>phantomjs download.js mytestfile.txt
