Hi,
I think your problem is with the fact the when using ${} it is calculated
before the actual execution of the code.
So it means that there is actually a static string in there and not a
random one.You may import the relevant jmeter class to your script and use it directly : http://jmeter.apache.org/api/org/apache/jmeter/functions/RandomString.html But I am unsure how exactly to accomplish this. Another option is to google for java random strings which will show you something like: public static String generateString(Random rng, String characters, int length){ char[] text = new char[length]; for (int i = 0; i < length; i++) { text[i] = characters.charAt(rng.nextInt(characters.length())); } return new String(text);} Good luck Shmuel Krakower. Beatsoo.org - re-use your jmeter scripts for application performance monitoring from worldwide locations for free.
