Replication Job Help

[hsturner]

Hi I am trying to set up a replication job between 2 Alfresco 4.2 Community installs and I keep getting this error:

<blockquote>Last job failed. Job started: Tue 29 Oct 2013 14:51:52 Ended: Tue 29 Oct 2013 14:52:03
09290126 Error executing transfer - 09290124 Failed to execute HTTP request begin to target: TransferTarget: Ypsi Alfresco Transfer Target,host:192.168.155.55,port:8443 status: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target</blockquote>

All I have done for modifying the back-end for replication is add replication.enabled = true to alfresco-global.properties.

I am still fairly new to Alfresco and java webapps so a starting point as to where I should trouble shoot this would be greatly appreciated.

It's an SSL problem rather than a problem with transfer.

I'm using port 8443 on both Alfresco installs.  Do I need a certificate, and if so where and how do I add the reference to the certificate?
