How to simulate client connections to Tomcat, Glassfish, JBoss

josecolella · 01-02-2013, 10:19 AM

Hello, is there a way to simulate client requests to a servlet of JSP(Java Server Page) such as ab for Apache that can simulate how long these servers take to service the servlet or JSP????

My favorite tool to check web server availability or to test page is curl:

curl -v http://localhost:8080/myservlet/index.jsp

will request index JSP page from your servlet and log in console headers and consumed time.

Regards,

Arnaud.

Thanks so much...I will use that...can curl be used to compare which of the three servers will respond to a client petition the fastest???...I know the network is a factor that will influence this as well, but can curl do a time comparison???

Will curl also work on java servlets that have deployed in the servers???

Good morning. I dont use this anymore, so i can't vouch for its current state, but in my old all-jboss shop it did wonders for us and was considered an alternative to expensive 'loadrunner' licenses.

Good luck!

edit: It is *very* in-depth, and very powerful, and feature-rich. It has a HUGE learning curve, at least it did for me, that is totally worth it.

curl is a command line browser. So it will not only work with servlet or jsp. It will work with any web page . It has hundreds of options to simulate what you want and is one of the best tool to write a shell script involving web page. AFAIK ab is for load testing. Though curl can be used to measure the response time. I don't think curl can be used for load testing servlet.
