Fwd: JavaSampler, complex response processing
Hi List,
Unfortunately nobody responded so far. I guess my mail was too
complicated in the first place. Let's try it step by step:
How do I fill a SampleResult wisely in the case of a complex answer
structure. I would love to return my own object, which is not
possible I guess so I need to wrap it up in the SampleResult and
extract it via a PostRegex.
Any Ideas? My original Question is further down for reference.
cheers,
Axel

Hi all,
I have some difficulties putting together a testplan for a EJB
Interface Test.
My Setup:
---
J2EE Container with a couple of Stateless Session Bean.
I would like to call the first (login) which comes back with the
sessionid and do a second, third, etc call using that sessionid.
---
I am not quite sure how to fill the SampleResult wisely. Especially
when I want to give back a complex Result. Concret my second Sample
would produce a List of a comlex result structure (list of business
items) and I need to pull some values out of the result within the Testplan.
Does anybody can give a example how to fill the SampleResult if the
Result is a somewhat complex structure in this case a list of
entities.
How do I use the following methods in this case of a JavaSampler?
void setContentType(String string)
void setDataEncoding(String dataEncoding)
void setDataType(String dataType)
void setRequestHeaders(String string)
void setResponseCode(String code)
void setResponseData(byte[] response)
void setResponseHeaders(String string)
void setResponseMessage(String msg)
void setSampleLabel(String label)
void setSamplerData(String s)
On which part of the result does the postprocessor work to pull out
the values using regexs?
Thank you very much for you help.
Cheers,
Axel

have you read this article?
http://www.javaworld.com/javaworld/jw-05-2000/jw-0526-testinfect.html
other people have come across this problem and there are JUnit based approaches to testing EJB that may be more suitable for your needs. good luck.

that definitely gives me a better idea, but I'm afraid there isn't a simple solution to your specific problem.

1. In the case I extend SampleResult (lets say AxelSampleResult), which would be fine with me. How
do I convince the framework to pull out the data of my specific
AxelSampleResult?
well you're going to have to write a specific visualizer to pull out the data. the stock components expect to get the data from either byte or string.
2. I do use a local interface in the Sampler. I do the whole JNDI
Lookup and Cast in the Setup and call my EJB, that does work fine so
far.

I am trying to use tha data from the first call and put it as input in
the second. Like this:
1. First Call: "SearchForSomething" --> "SearchResult"
2. Second Call: "DoSomething" use some values from SearchResult
Using that I would like to simulate a whole UserSession. Somebody
logs in, is doing a search and is modifying one Resultset using the
next funktionality, etc.
Ok, this is going to be hard. If your sample converts the EJB session information into HttpSession data, then you would be ok. Otherwise you'd have to write a custom configuration element to handle EJB related session data.

Does that help helping :-)
Cheers,
testing EJB's can be a bit of a pain. If you read the latest threads on theServerside.com, you'll lots of people complaining about how hard it is to test EJB effectively. It can be done, but it's not easy or painless. I hope that helps provide some useful answers.

hi Axel,
you're probably going to have to extend SampleResult, or try to wedge it into the existing one. Are you planning on using a local interface to call the EJB or do a real remote call?
if you're goal is to measure how long it takes to get data, you probably should be using local interface to get the data. In that case, you can just use the built in timer. If you want to view the data, you're going to have to either pass the bytes, convert to string, or extend SampleResult to take an object for the response data.
a bit more information about the goal of your test would make it easier to provide useful suggestions :)
