I can’t answer your direct question, however, it may be easier to go with a reverse-proxy
setup where nginx or apache handle SSL and forward requests to tomcat. There are many
guides to getting nginx very secure[1], and I just found this guide[2] which fixes a few
reverse proxy issues[3] between nginx and tomcat.
Perhaps search around on that and see if it fits your needs.

Greets,
I've enabled HTTPS on my XWiki. But when I surf there, I get a failure with no
explanation from Chrome, and this from IE:
--------------------------------------
Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to
https://pwswiki10.westmarine.net again. If this error persists, it is possible that this
site uses an unsupported protocol or cipher suite such as RC4 (link for the details),
which is not considered secure. Please contact your site administrator.
--------------------------------------
When I hit the site with this nmap command to enumerate the available ciphers, I get
none.
# nmap --script ssl-enum-ciphers -p 443 pwswiki10
I googled it, and it looks like there was once some text about this problem on the XWiki
site, something about re-enabling TLS, but when I click the link I land on the
administration manual's Configuration page, which has a lot of good stuff but not the
bit about re-enabling TLS.
I found the "ExcludeCipherSuites" section in jetty-ssl.xml, and tried
commenting it out, but still get no ciphers.
I tried adding the following section, but still get no ciphers:
----------------------------------------------------------------
<Set name="IncludeCipherSuites">
<Array type="java.lang.String">
<Item>TLS_RSA_WITH_AES_128_CBC_SHA</Item>
<Item>TLS_RSA_WITH_AES_256_CBC_SHA</Item>

<Item>TLS_RSA_WITH_AES_256_GCM_SHA384</Item>
</Array>
</Set>
--------------------------------------
Seems like maybe I need to find the equivalent of this line from httpd.conf:
SSLProtocol -ALL +TLSv1.1 +TLSv1.2
I am searching the archives. Meanwhile can anyone point me to what I am doing wrong /,
or to an example of how that IncludeCipherSuites block should be?
Thanks
Doug
