empty variables in some cases
hi,
I'm using jmeter to test some servlets on our webapplication server.
The servlets respond with xml code and I extract variables from that
by XPath. The problem is, that in some cases the variables are empty
when I use them in some request situation.
The following structure works:
Thread Group
- Create Reseller
- create request
- xpath -> rorgid
- Loop (Create Provider)
- create request (with rorgid var)
- xpath -> porgid
- create service request (with rorgid var)
- request with porgid
But when I move "create service request" up before loop, then the
provider create request doesn't get the rorgid value any more. The
same happens when I move "create service request" after the "xpath ->
porgid" element, the "request with porgid" gets an empty variable.
I'm using svn version 556204 from nightly builds.
cheers,
dominik

Post-Processors are run after every sampler in scope, so unless you
add them as a child, they may be applied to more samples than you
want.

hi sebb,
thanks for your help! It works now :)
The mistake was, that we used the XPath extractor directly after the
request. After a few tests, we find out that the XPath extractor must
be used as child of the request, otherwise the results gets lost when
used once. (I'm not sure if that is a bug or expected?)
cheers,
dominik

The test plan is not entirely clear to me, but it sounds like it
should work. I suggest you:
1) Check the JMeter log file for any errors
2) Ensure that you use a default value to catch any XPath match
failures - the variable should then be set, even if it is to the wrong
value. If not, investigate further.
3) Try adding a Java Request sampler to display the value of the
variable at various points,
