SyntaxError：节点Javascript中出现意外的令牌ILLEGAL

Question

I am trying to execute a command using node JavaScript.

var spawn = require('child_process').spawn,
   cmd  = spawn('java -cp C:\Java\jdk1.7.0_45\lib\dom4j.jar;C:\Java\jdk1.7.0_45\lib\geronimo-stax-api_1.0_spec-1.0.1.jar;C:\Java\jdk1.7.0_45\lib\gson-2.2.4.jar;C:\Java\jdk1.7.0_45\lib\mysql-connector-java-5.1.6.jar;C:\Java\jdk1.7.0_45\lib\ooxml-schemas-1.0.jar;C:\Java\jdk1.7.0_45\lib\poi-3.9-20121203.jar;C:\Java\jdk1.7.0_45\lib\poi-ooxml-3.9.jar;C:\Java\jdk1.7.0_45\lib\xmlbeans-2.5.0.jar;C:\Java\jdk1.7.0_45\lib\xmlbeans-xmlpublic-2.6.0.jar;C:\Java\jdk1.7.0_45\lib\excelreader.jar astral.excelreader.Main 11 33 fsdds', []);

Then it is showing the following error:

SyntaxError: Unexpected token ILLEGAL
    at Module._compile (module.js:439:25)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:901:3

If I remove these two jars (C:\\Java\\jdk1.7.0_45\\lib\\xmlbeans-2.5.0.jar;C:\\Java\\jdk1.7.0_45\\lib\\xmlbeans-xmlpublic-2.6.0.jar;) from command then it is not showing the above error. But I want some class files in that jars.

If I run the first command directly in windows command prompt(without using node js) then it will execute correcty. Anybody know why that error comes if I add these following jars? C:\\Java\\jdk1.7.0_45\\lib\\xmlbeans-2.5.0.jar; C:\\Java\\jdk1.7.0_45\\lib\\xmlbeans-xmlpublic-2.6.0.jar;

Answer 1

String c:\\windows\\ in javascript should be like this:

c:\\windows\\

And spawn syntax: spawn(command, [args], [options])

spawn('java', ['-cp', 'c:\\java\\...'])

Answer 2

You have to double the backslashes. Instead of

'java -cp C:\Java\jdk1.7.0_45\lib\dom4j.jar;...'

write

'java -cp C:\\Java\\jdk1.7.0_45\\lib\\dom4j.jar;...'
