APPLIES TO:

Oracle Commerce Platform - Version 9.4 and later
Information in this document applies to any platform.

Cause

Some of the SQLrepositories were modified with custom properties descriptors and ACC is not able to find them while start up.

SOLUTION

Please configure the application module with the following entries in the module's MANIFEST.MF file:

ATG-Client-Class-Path: A listing of the jar files that will added to the ACC client's classpath
Name: The filename of each jar file entry in the ATG-Client-Class-Path that needs to be downloaded
ATG-Client-Update-File: A true or false flag whether or not the filename should be downloaded by the ACC
ATG-Client-Update-Version: Optional version string used to force the ACC to update the specified filename

If you see the MANIFEST.MF file in PCIencryption module and it doesn't have the above entry. So please add the below 3 entries in the MANIFEST.MF file of PCIencryption Module.

ATG-Client-Class-Path: bin/
Name: bin/
ATG-Client-Update-File: true

ATG-Version is not required.  Do a build and start the server and try to access ACC through script or dyn/admin . You should be able to access it.

Not able to access User / Profile Repository in ACC

APPLIES TO:

Oracle Commerce Platform - Version 9.4 and later

Cause

This error is because your particular Repository in ACC is not able to find particular class to load the properties of the xml.


e.g when you click on Users or Orders in ACC, above error appears in front of you.

Solution

So the solution is , find out if there are any external classes used for your repository. In my case pci encryption was used to encrypt password in UserProfile.xml and ACC was not able to locate that class when loading the particular repository.

So Add following lines in pci encryption module :

Go to encryption module MANIFEST.MF file

Add line ATG-Client-Class-Path: bin/ config/config.jar lib/classes.jar

Build project wit ANT and restart the server.

Cheers!!!
