+== How to run JMeter test plan programatically, such as from an Ant script? ==
'''Answer:''' Quick answer, go here: http://www.programmerplanet.org/ant-jmeter/. I have permission from the author of this ant task to add it to JMeter's distribution, which I will do as soon as I have the time.["It should now be in the extras folder"].

+== How can I do stress testing of EJBs? ==
'''Answer:''' You can use the JavaSampler classes to write your own class that runs your EJB's, and then JMeter will take over the threading and reporting. This, however, is not ideal. Someone needs to write a good EJB Sampler implementation for JMeter (hint, hint).

-''Why do HTTP 3xx redirects appear as errors ? Is there a way to make them appear as HTTP 200 OK''
+== Why do HTTP 3xx redirects appear as errors ? Is there a way to make them appear as HTTP 200 OK ==
'''Answer:''' Quick answer: They appear as an error because 302 != 200, at least in v 1.8.1.
Long answer: try using v1.9RC1, the code in [http://cvs.apache.org/viewcvs.cgi/jakarta-jmeter/src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPSampler.java?rev=1.40&content-type=text/vnd.viewcvs-markup HTTPSampler] seems to take into account the result code for the redirect instead of the redirect result code.

When you view the results in the View Results Tree, you can see the ${category} value was replaced with the value from the User Parameters. Each thread will use the category from the User Parameter setting automatically. If there are more than two threads, they will reuse the values in these settings, so the third thread would use DOGS.

You can use the Regular Expression Post Processor to extract a value from a response, and then reuse this response in another request. Looking at the previous question in this FAQ, you could extract the product id from the result and use it in the following request:

N.B. If using such a script in client-server mode, make sure that any data files are copied to the appropriate place on the server host, as the files will be opened by the server process, not the client.

'''Answer:''' It's a great idea to write some glue between JMeter and JUnit for just this purpose. It doesn't exist currently, though there is an Ant task for JMeter that you might find useful.

-'''Question:'''''What Pattern matching (regexen) does JMeter support?''
+== What Pattern matching (regexen) does JMeter support? ==
'''Answer:'''JMeter includes the pattern matching software [http://jakarta.apache.org/oro/ Apache Jakarta ORO]. There is some documentation for this on the Jakarta web-site. There is also documentation on an older incarnation of the product at [http://www.savarese.org/oro/docs/OROMatcher/index.html OROMatcher User's guide], which might prove useful. The pattern matching is very similar to the pattern matching in Perl. A full installation of Perl will include plenty of documentation on regular expressions - look for perlrequick, perlretut, perlre, perlreref. O'Reilly sell a book called "Mastering Regular Expressions" by Jeffrey Friedl which will tell you all you need to know (and a lot more) about regular expressions. There are a couple of chapters available on their web-site covering REs in Java and .NET, and the Java chapter has a [http://www.oreilly.com/catalog/regex2/chapter/ch08.pdf section on ORO (PDF)] - worth a look.
