java force literal when using escape character in jmeter

Question

Running Jmeter on XP, I have the following scenario:

Declare the variable "ServerName" with the value 'serverNameValue'
Declare the a variable "TestResultsFolder" with the value 'c:\results\${ServerName}'
... do samplers ...
Have a simple data writer save result to "${TestResultsFolder}\file"

Unfortunately, The data writer is saving to 'c:\results\${ServerName}' instead of 'c:\results\serverNameValue'

if I put a valid alpha character before the variable, it works: 'c:\results_${ServerName}' yields 'c:\results_serverNameValue'

Thus, it seems that the \ is escaping the variable declaration of $, causing the program NOT to supply the correct value.

Any thoughts on how I might actually obtain c:\results\serverNameValue

Answer 1

Does the '\' character have to be escaped, in order to explicit that you need a real '\', and not an escape of the next character?

I would try this : "c:\\results\\${ServerName}"
