Java Runtime.exec()

I can run this command from the command line without any problem (the validation script executes):

c:/Python27/python ../feedvalidator/feedvalidator/src/demo.py https://das.dynalias.org:8080/das_core/das/2.16.840.1.113883.4.349/1012581676V377802/otherAdminData/careCoordinators 

and from java if I leave off the URL parameter and just do:

String[] args1 = {"c:/Python27/python", "../feedvalidator/feedvalidator/src/demo.py" };

Runtime r = Runtime.getRuntime();

Process p = r.exec(args1);

it works fine. If I use certain URLs for a parameter such as:

String[] args1 = {"c:/Python27/python", "../feedvalidator/feedvalidator/src/demo.py" , "http://www.intertwingly.net/blog/index.atom"};

// or 

String[] args1 = {"c:/Python27/python", "../feedvalidator/feedvalidator/src/demo.py" , "http://www.cnn.com"};

it also works fine.

But if I use this particular URL https://das.dynalias.org:8080/das_core/das/2.16.840.1.113883.4.349/1012581676V377802/otherAdminData/careCoordinators, then the script just hangs (java waits for the process to finish). I’m not sure why it works from the command line for that URL but not from a java program. I tried adding quotes to surround the URL parameter but that didn’t work either. I don’t see any character in the URL that I think need to be escaped.

Full Code:

String urlToValidate = "https://das.dynalias.org:8080/das_core/das/2.16.840.1.113883.4.349/1012581676V377802/otherAdminData/careCoordinators";



String[] args1 = {"c:/Python27/python", "C:/Documents and Settings/vhaiswcaldej/DAS_Workspace/feedvalidator/feedvalidator/src/demo.py", urlToValidate };

System.out.println(args1[0] + " " + args1[1] + " " + args1[2]);



Runtime r = Runtime.getRuntime();

Process p = r.exec(args1);

BufferedReader br = new BufferedReader(new InputStreamReader(

p.getInputStream()));

int returnCode = p.waitFor();

 System.out.println("Python Script or OS Return Code: " + Integer.toString(returnCode));

if (returnCode >= 2) {

    .out.println("OS Error: Unable to Find File or other OS error.");

    }



String line = "";

while (br.ready()) {

     String str = br.readLine();

     System.out.println(str);

     if (str.startsWith("line")) {

     //TODO: Report this error back to test tool.

     //System.out.println("Error!");

     }

     }
