Store a long value to a variable in Jmeter using preprocessor and print/use the same value in a sampler

below are the steps i followed, 1) Added a BeanShell sampler and add a Bean Shell Preprocessor to the same sampler.

long c = 25478995L;
log.info(c + " - It is long");
vars.put("c",c)

2) I am trying to print the value c in Bean Shell sampler like below,

${c}

3) But when i see in view result tree i am getting the ${c} instead i am expecting to view 25478995.

Can any one help me please. Thanks in advance.

Solution

If you want to store a Long per se you need to use vars.putObject() function instead like:
```
vars.putObject("c", c);
```
and later on:
```
log.info("My long value is: " + vars.getObject("c"));
```
If you want to have String representation - you need to convert your Long to String first like:
```
vars.put("c", Long.toString(c));
```
Don't refer variables like ${c} in scripts, use vars.get("c"); or vars.getObject("c"); instead
Since JMeter 3.1 it is recommended to use JSR223 Test Elements and Groovy language rather than Beanshell for performance reasons, see Apache Groovy - Why and How You Should Use It for more details.
