Error generating variable with 44 characters in Jmeter

hello!

I have the following problem in Jmeter:

I want to add a code to my BeanShell Tester that generates a 44-character barcode. But so far, without success.

So I went to plan "B":
I added a Random Variable with 44 characters, but it doesn’t get created. It does not display any errors.

Could someone help me and tell me what I can do to make it work?

Below are the variables:

Output format: 0000000000000000000000000000000000000000
Minimum value: 1000000000000000000000000000000000000000
Maximum value: 9999999999999999999999999999999999999999

Print below:

As for the code, I didn’t share it here, but if anyone knows and has a code that generates barcodes, I’d appreciate it!

Anyway, that’s it folks!

Thank you very much in advance!

>Solution :

If you’re doing Beanshell scripting (however since JMeter 3.1 you should be using Groovy) the better option would be doing something like:

vars.put("CodeBarra", org.apache.commons.lang3.RandomStringUtils.randomNumeric(44));

Alternatively you can use it in __groovy() function:

${__groovy(org.apache.commons.lang3.RandomStringUtils.randomNumeric(44),CodeBarra)}
