How do I call function passing in script variables

I was able to get jMeter to include a file with beanshell functions in it automatically by using the
property:
beanshell.function.init=BeanShellFunction.bshrc

However, I have a function which I want to use that will take a SampleResult and do some modifications (basically its an xml document but its not well formed in that it has multiple top level nodes, I want to wrap it and modify it.. I've got all this working but I can't get it working within a function).

here is what I have:
print("including functions");
wrapResponse(SampleResult result, String prefix,String suffix, ) {
        log.info("Calling wrapResponse");
        encoding = result.getDataEncodingWithDefault();
        String data = prefix + (new String(result.getResponseData())) + suffix;
        result.setResponseData(data.getBytes(encoding));
}

I know that this file is being included but i can't seem to pass the result value to the function.

This is within a BSF PostProcessor which has a prev variable which has the response in it (like I said, i've verified this works when not in a function).

The string values pass just fine though..

I'm calling it like this:
${__BeanShell(wrapResponse(prev\,"<tiqs>"\,"<tiqs>"))}



Here is the error message:

After playing around with it and reading some more documentation I figured out how to do it.
I needed to 1. Import the right package to use a SampleResult in my script file:
import org.apache.jmeter.samplers.SampleResult;

print("Including user defined functions");
wrapResponse(SampleResult  result, String prefix,String suffix) {
        log.info("Calling wrapResponse");
        encoding = result.getDataEncodingWithDefault();
        String data = prefix + (new String(result.getResponseData())) + suffix;
        result.setResponseData(data.getBytes(encoding));
}

Then I called it like this:

${__BeanShell(wrapResponse(SampleResult\,"<tiqs>"\,"<tiqs>"))}

I'm not sure how I could have accessed the prev value that is set for the script, but the documentation said that there was a SampleResult variable for the __BeanShell function and that did in fact work.

The BeanShell function documentation does not mention "prev" at all:

http://jakarta.apache.org/jmeter/usermanual/functions.html#__BeanShell

However, "prev" is set for some of the BeanShell test elements - but
they are not functions...

Sorry maybe what I said was confusing.
I was using a BSF PostProcessor which mentions a "prev" variable which I originally was using in a script right within jmeter, and it worked fine.. Problem was I needed to do that same thing over and over, so I figured it would be better to put the logic into a function that would be available to any beanshell script. So i made my own beanshell file with functions in it, used the property:
beanshell.function.init (as described in the documentation) and referenced the file from a  user.properties file, and pointed it to my beanshell script. I got that working just fine but couldn't figure out how to pass the prev variable to the script. Originally I tried calling the function directly from the script, but that didn't work (btw, is there anyway to do that without using the __BeanShell function?)
It would sure be great if in the script section of the bsf postprocessor if I could just call the function I created directly. Anyways, I figured that the SampleResult value was the same thing as the prev variable in this case, i was just kind of curious if I could use the variables exposed in the script section rather than just those exposed to the __BeanShell function.

That won't work with a postprocessor, it's only for actual BeanShell
function calls.
You need

beanshell.postprocessor.init=etc

I don't think you need to - just reference the variable.

You can call functions directly.

You can,  but you need to use the correct init file ...

Re: How do I call function passing in script variables

Your right!
Setting the property to
beanshell.postprocessor.init=functions.bsh
did the trick.
I also had to switch my post processor from BSF to beanshell (which i suppose is basically on the same thing since I was using the beanshell language from the bsf post processor).

Thanks for you help

That won't work with a postprocessor, it's only for actual BeanShell
function calls.
You need

beanshell.postprocessor.init=etc

I don't think you need to - just reference the variable.

You can call functions directly.

You can,  but you need to use the correct init file ...

It's not the same. The beanshell.<type>.init properties only apply to
the BeanShell test elements.

The properties are described in the jmeter.properties file.
