Our application that I am trying to load test is a servlet based application. The \
servlet receives data collected by agents setting on various systems via an https \
post. There is a post parameter named Data which contains a string that contains 5 - \
20 lines of data (in CSV format with the \r\n sepreating each line). I am trying to \
fill that parameter with data that will not violate any of the key fields when the \
servlet processes it and eventually stores it into a database. Thus each record must \
be unique as it is created by each thread in JMeter. I created a BeanShell Script \
(about 15 lines) that successfully created the unique lines of data. I am thinking \
that what I am going to have to do is create one large file containing the data \
strings (containing unique data in the CSV and \r\n separated format), then allow the \
thread group to read the file line by line setting the parameter in each thread to \
the next line in the file.
Hopefully that makes sense as to what I am trying to do

Indeed, it is a script, not a script file name. I've updated the help to
make this clearer. The Function Helper (^F) is already a bit clearer.
I think you could use a script consisting of the function call
${_StringFromFile(scriptfile)}
and that would read a single line from the file and return it to the
beanshell function for processing. Not ideal, but it should work.
What are you actually trying to do?

Thanks for the info. My help document referred to the first parameter as a
script (see below), so I thought a script file would be accepted. Since I
now know differently I will have to fill the http parameter differently. I
will probably use the CVSRead function. Again thanks for the clarification.
16.5.13 __BeanShell
The BeanShell function evaluates the script passed to it, and returns the
result.
Parameters
Attribute Description Required
BeanShell script A script Yes
Name of variable A reference name for reusing the value computed by
this function. No

Unlike the Beanshell Sampler, the BeanShell function does not accept input
from a file.
Have a look at Function Help; the two parameters are:
* the expression to evaluate
* the name of the function.
A file name is not normally also valid as a java expression ... I leave as
an exercise for the reader to find one!
