How can I access the cookie manager in beanshell?

Question

I have seen many examples but none seem to work.

This is what I have setup:

I'm using a foreach to loop through my variables and have Cookie Manager use them:

I want the beanshell to clear the cookies in the cookie manager on each loop so they get re-added from my vars, but I can't seem to access it.

I tried the following:

import org.apache.jmeter.protocol.http.control.Cookie;
import org.apache.jmeter.protocol.http.control.CookieManager;

manager = sampler.getCookieManager();

That gives me this error:

Attempt to resolve method: getCookieManager() on undefined variable or class name: sampler

I tried doing this:

CookieManager cManager = ctx.getCurrentSampler().getCookieManager();

But that gives me this error:

Typed variable declaration : Error in method invocation: Method getCookieManager() not found in class'org.apache.jmeter.protocol.java.sampler.BeanShellSampler'

Edit: So as per a suggested solution I tried this:

And then this:

But that gives me this error:

Answer 1

Don't use Beanshell because of Performance and it will be removed in future versions.

• Add a JSR223 PreProcessor on the first HTTP Request
• Select Groovy
• Check "Cache compiled script if available"
• Add following code:

import org.apache.jmeter.protocol.http.control.CookieManager; import org.apache.jmeter.protocol.http.control.Cookie; CookieManager cm = sampler.getCookieManager(); cm.clear();

This is what it should look like
