How to put an ArrayList<String> object to the props variable of jmeter and use it from Beanshell script

Question

I am trying to do this from a beanshell sampler.

import java.util.List;
import java.util.ArrayList;

list = new ArrayList();
props.putObject("list", list );

Now from another Beahshell sampler I want to do this.

list = props.getObject("list");
list.add("Rajan");

And then from a third Bean shell sampler

log.info("The list is " + list );

The code will work if we use vars instead of props. But the scope of vars is inside a single thread only. I want an array object in the scope of the test plan. The code throws an error. seems like props is a java.util.Properties class and cannot hold objects. Any idea how to do this.

In file: inline evaluation of: ``import java.util.List; import java.util.ArrayList; //Prints the report list = n . . . '' Encountered "<" at line 5, column 21.

Answer 1

props is, as you said, an object of type java.util.Properties, which is a subclass of Hashtable. Therefore you can use put and get methods:

props.put("list", list );

list = props.get("list");

However, The javadoc says this is "strongly discouraged" because it could break other operations on Properties. So use it at your own risk.
