We are developing an application that uses a java api (restfb) to read data from facebook pages. For persistance purposes, we decided to utilize EMFStore. However, after a workspace is created:

 ESWorkspace workspace = ESWorkspaceProvider.INSTANCE.getWorkspace(); 


every call of the restfb api results in a SunCertPathBuilderException (see below). This error does not occur without running EMFStore.
Any suggestions and ideas are much appreciated!

Hi Joshua,

this most probably happens because EMFStore ships with its own keystore
which does not contain the necessary certificate(s) for Facebook when
trying to create the SSL connection.
Could you import the respective certificates into EMFStore's keystore
(which can be found at $HOME/.emfstore/client/profiles/<YOUR_PROFILE>)
and try again? A good tool for managing Keystores via a UI is the
Keystore Explorer (http://www.keystore-explorer.org).
Hope this helps.

Cheers,
Edgar

Hey Edgar,

thanks for the help. We found that EMFStore changes the system properties to point to its own keystore/trustsore locations, so we changed them back for now, until we know which certificate facebook connections require.

Have a nice day!
