Can I do packet sniffing out of the box on OS X?

Can I do packet sniffing out of the box on OS X? I'm doing some development, a Java app that communicates via HTTP. The log4j isn't helping me much so I'd like to see the actual HTTP Request that I am creating once it gets sent out.

turns out that tcpdump is an easy way to do it out of the box.

"HTTPScoop does perfectly the job for simple http sniffing.

Although a bit old fashion looking still worth to mention Eavesdrop for general basic sniffing"
