certmonger doesn't support storing certificates in a java keystore.
certmonger has the concept of pre and post renewal scripts so you can,
for example stop or start a service, or import a renewed certificate
somewhere else (IPA uses this to store a copy of some certificates in LDAP).
So theoretically certmonger could for example, track PEM files in the
filesystem and upon renewal run a post script to import the updated cert
into the java keystore.
The tricky bit might be in dealing with the CSR. certmonger needs the
private key in order do the renewal.
I guess one thing you could do is a straight ipa-getcert -f
/path/to/cert.pem -k /path/to/key.pem ... <other options> -C
Then take the resulting PEM files, create a PKCS#12 file out of them,
and import that into your java keystore. Then all renewals will run that
post-script which you can setup to update the cert in the java keystore.
I don't know much at all about java so there is a lot of hand waving
going on. I hope some of it makes some sense/is doable.
