icedtea-web package included with the distros is the plugin that handles javaws
for firefox for both RHEL/CentOS 6 and 7 and openjdk. I have yet to find an app
that cannot use openjdk instead of oracle java. It may be a little less
streamlined, but it's functional. Ignore/cancel any pop ups that talk about
updating java.
If I missed this answer, I apologize as I receive the digests.

Don't know about CentOS6, but with CentOS7, the selection of apps that
you can use appear to map to '.desktop' files?
If it is the same on CentOS6, then you might be able to set up a
suitable .desktop file (e.g. in /usr/share/applications/ or similar) to
do what you want ...
No idea if this is of any help
