AEM Forms 6.2 -Reader Extension pfx file in AEM


Level 4


Following the setup i can upload a reader extension PFX file to AEM ( )

What i try to do in a servlet is to create a resource for the a services user "resolverFactory.SUBSERVICE".  Use the keystore of the services account to retrieve the RE key for my document.

Question, can a keystore for a services account be used to store the readerExtension key? When i want to retrieve the keystore  i got an error: "The provided userId does not identify an existing user." for "com.adobe.granite.keystore.internal.KeyStoreServiceImpl.retrieveUser("

I had the same problem , but was able to reader extend without any user associated with the session

Did you attached the extension to a services account or a “normal” user account such as admin.?

(btw: every session has a user attached to it; Session.getUserID() will return you the String value)
