Moving to servlet 3 as the base?

Hi,

right now, Sling in theory runs on servet 2.4 and we have to do some
ugly tricks to support 2.4/2.5 and 3.x.
I think 3.0 is now out long enough that we could "upgrade" and require
3.0 as the base and get rid of all the special handling.

WDYT?

Definitely, thanks for researching this and +1 to the move.

For the record, here are the oldest versions of some application
servers that support Servlet 3.0:

- WebSphere Application Server 8.0 ( Jun 2011 )
- WebLogic Server 12c ( Dec 2011 )
- Tomcat 7 ( Jan 2011 )
- Jetty 8 ( September 2011 )
- JBoss EAP 6 ( June 2012 )

I imagine there might he people running on older versions of these
application servers but 2011-2012 looks recent enough for me to
require it in Sling.

+1 for moving to Servlet 3.0

Robert

Would that work for people running Sling on enterprise application
servers, as opposed to using the embedded Jetty server?

I'm (luckily) not familiar with those environments but I suppose they
might be slower to provide the latest stuff that more lightweight
environments.

It would be useful for the Resource Editor.
