Hi,

I added the following command to my code:

ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1",
"myArg2");

and got this error message:
"The constructor ProcessBuilder(String, String, String) is undefined"

Does anyone knows what's the problem?

Thanks.

Perhaps what Sun *meant* to say at the top of their 1.5
JavaDocs for ProcessBuilder was..

String[] commands = {"myCommand", "myArg1", "myArg2"};
ProcessBuilder pb = new ProcessBuilder(commands);

..note the array of commands, which matches this constructor.

lder(java.lang.String...)>

I gather you are using a pre 1.5 java. ProcessBuilder( String...) was
only invented with 1.5.

prior to that you would have had to use new Strin[] { .... };

see http://mindprod.com/jdk.html
to get 1.5. It is about a year old now.
