Launch url on Java by command line

Question

I have a issue for this code . Please help me review :

Runtime.getRuntime().exec("cmd.exe /c start chrome " + url);

This code is OK if I launch the url which does not contain parameter, but i put parameter to this url,the link does not work and dont see parameter on url. thanks

Paste the url that is causing the problem. I think the problem may be due to not escaping back slashes. — Urban

This url runs on local. Example : 127.0.0.1/acb/display.do?user=abc&password=123 — baopham

Try this:

Runtime.getRuntime().exec("cmd.exe /c start chrome \"" + url + "\"");

The url contains various symbols that cmd may think illegal to use. For example

 cd new folder

is illegal as there is a space between so u must use

cd "new folder"

Just the same you must enclose the url in "" to make it work. Thus you must use:

Runtime.getRuntime().exec("cmd.exe /c start chrome \"" + url + "\"");

Or use this to directly launch the url in default browser:

Desktop.getDesktop.browse(uri);

Note wherever there is a \ in the url you must use \\ in place of it. So that java doesnot mistakes it as an escape sequence.

"So wherever there is a / in the url you must use // in place of it." No, that is only the case for back-slash (\).
