WebSphere Application Server - Liberty Profile - Oh, what fun

I installed it on my Mac a while back, so it was an easy task to find it and fire it up.

This is what I did ( from Terminal ): -

$ cd ~/wlp

$ cd bin

$ ./productInfo version

$ ./server status

$ ./server start

$ ./server stop

I then deployed a web application ( SuperSnoop ) from this old-but-useful IBM Techdoc: -

Snooping on your Webserver with the SuperSnoop Servlet [PDF]

This document is almost 10 years old, dating from September 2004, but the Snoop servlet contained therein is still useful.

I'd previously packaged the sample Javacode up into a WAR file - SuperSnoopWeb.war - so it was a simple matter to place the WAR file and then restart the Liberty server: -

$ cp ~/SuperSnoopWeb.war ~/wlp/usr/servers/defaultServer/dropins

and then start the defaultServer instance again: -

$ ./server start

and check the logs: -

$ cat ~/wlp/usr/servers/defaultServer/logs/console.log 

and then test the SuperSnoop Servlet: -

Note that the dropins folder ( ~/wlp/usr/servers/defaultServer/dropins/ ) provides the mechanism for …. well, dropping WAR files in ( and out ) of the Liberty configuration without the need to actually deploy the WAR file ( which typically requires an edit of the server's configuration file ( ~/wlp/usr/servers/defaultServer/server.xml )

In other words, it's the lazy solution :-)

As ever, #LifeIsGood

What's next ?

I note that I'm still running Liberty 8.5.0.2, and strongly suspect that there's an updated version out there i.e. 8.5.5.1, so I'm off to the web to get a new wlp.jar file :-)

Here's some required reading for you: -

WebSphere Application Server V8.5.5 Liberty Profile - Test drive Liberty, the WAS profile designed for developers.

*UPDATE* 17 January 2014

Yep, and now I have 8.5.5.1 installed: -

$ ./wlp/bin/productInfo version

Product name: WebSphere Application Server
Product version: 8.5.5.1

 $ cat ./wlp/usr/servers/defaultServer/logs/console.log
