Other samplers return all the data in the sample itself, and JMeter uses Regex or XPath Post-Processors to retrieve the information as required. So long as the data is reasonably well-laid out, this is quite easy to do. In the case of the EJB sampler, perhaps it could have returned data in XML format. Another approach (not necessarily better) is to save some values in variables, and use the new variable-saving functionality: http://jakarta.apache.org/jmeter/usermanual/listeners.html#sample_variables > > > It all worked for the purpose of that project.

The RE Post-Processor only applies to Body, Headers, URL, Response Code, Response Message http://jakarta.apache.org/jmeter/usermanual/component_reference.html#Regular_Expression_Extractor If you are prepared to write some Java you could of course use the BeanShell Post-Processor to do anything you want, including accessing dataType. But BeanShell can use a lot more resources. > From what I've read I need to add a child regular expression extractor to > each EJB request, however I don't know what syntax I should be using in the > regular expression component to retrieve sampleresult attributes. You can only access the attributes (fields) as per the "Response Field to check". REs can be used to extract all or part of the selected field, exactly as for HTTP samples. > I'm also concerned as I can only see some of my attributes in sampler result > tab of my view result tree listener.Could this be because I've overridden the > dataType attribute on the sampleresult ? > Probably. > > > > Any help is really appreciated. > > > > > > Thanks > > > > > > Greg Peace > > > ________________________________________________________________________ > AOL Email goes Mobile!
