hi tandraschko,
So I had to downgrade atmosphere runtime to 1.0.19 so that i may run on servlet 2.5 wls.
How should I use the pf push framework to utilize the 1.0.19 runtime? I don't mind using deprecated classes as long as they can just run.
I changed the code that was like so:
to :
how do i correctly initialize the web.xml?
Thanks in advance.
BR,
Johan

I am guessing due to my web.xml:I still get SEVERE: Servlet /tjsf2011 threw load() exception

I'm almost sure that you need a newer version of atmosphere as 1.0.x, so that it will work with PF6. So there is no solution for now, sry.
Also remember: Java6 is EOL since some years So we won't do any hacks for you.

yep, i know but maybe should talk with your admins to get java7
You have one chance: create a issue on atmosphere side, so they can introduce java 1.6 compatible again. PF still compiles on java 1.6.

I had the same problem and just clone the git repo and checked out branch atmosphere-2.4.x and reset to the tag 2.4.3 (the version which is referenced by primefaces6). I only had to adjust the parent pom.xml and remove all the diamond operators <> inside the collection ctor calls. And in one class i wraped Exceptions in RuntimeExceptions (check the git patch below).
I needed that because my Websphere 8 runs on java 6. I didn't get it running on Websphere (because of another problem => annotation scanning might be not working correctly because no Atmosphere Handlers are created) but with Liberty Profile Server it works.
Here is the patch:
