For extruded aluminum, find the local distributor for aluminum structural framing in your area. Try 8020.net in the US and Bosch-Rexroth in Europe. You might also try frontpanelexpress.com, though their stuff might be too big.

Here are some options to mount the PCB:


The slots
PEM studs (you'd need a fabricator to press these in for you)
Bolts and standoffs (try Digikey)


For the PEM studs, check out the KSSB family-- they're designed specially for mounting PCBs without extra fasteners.

Mounting a PCB in an Extruded Aluminum case
I am using Tomcat6.0.29. When I try to close Tomcat using shutdown.bat, it is not shutting down tomcat and also I don't see any update in log file for what happened. If I try to use "catalina stop" at the command prompt, I get the following error. 

__Error: transport error 02: bind failed: address already in use
error: JDWP Transport dt_socket failed to initialize. Transport_Init&lt;510&gt;
JDWP exit error AGENT_ERROR_TRANSPORT_INT&lt;197&gt;: No transport initialized{../../..src/
sare/back/debugInit.c:690}
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT&lt;197&gt;__


Please let me know what should I do to fix this error. Thanks in advance
