use jar file + Dynamic values into the loop counter - Jmeter

Question

I want use improved version of: How can i use jar file into loop counter - Jmeter

//jar data

public class PabBDetailsIncluded {

public static String ARGENTINA(String sourceAccount)
    {
        String a = 
                "{"
                + "\"money\": {"
                + "\"amount\": 10,"
                + "\"currency\": \"EUR\""
                + "},"

                + "\"description\": \"Payment\","
                + "\"sourceAccount\": " + sourceAccount + ","



                + "}"
                + "}";

        return a;
        }

1) with above data i want to 'feed' Jmeter call

just instead of all values to be static from the jar file, i want to pass 'sourceAccount' during the execution, rather then being hard-coded into the jar file.

2) i tell loop counter to count with: ${__groovy(com.example.TestData.getDeclaredMethods().size(),)}

3) into JSR223 PreProcessor "Script" area is like:

    import com.example.PabBDetailsIncluded;

def sourceAccount = vars.get("accountNumberLogger");


def testData = new com.example.PabBDetailsIncluded()
def methods = testData.class.getDeclaredMethods(sourceAccount)
def payload = org.apache.commons.lang.reflect.MethodUtils.invokeExactMethod(testData, methods[vars.get('__jm__Loop Controller__idx') as int].getName())
sampler.addNonEncodedArgument('',payload,'')
sampler.setPostBodyRaw(true)

The error i got is:

If i use the data from jar file without dynamic values, everything is ok.

Any help would be appreciated.

This is not the same as for some reason you're using static function which needs to be called a little bit differently.

Moreover now you need to pass the parameter to the function and I fail to see where you're passing this parameter.

Your code needs to be amended to look like:

def sourceAccount = vars.get("accountNumberLogger")
def testData = new com.example.PabBDetailsIncluded()
def methods = testData.class.getMethods()
def payload = methods[vars.get('__jm__Loop Controller__idx') as int].invoke(testData, sourceAccount)
