Hi Manish, First, a disclaimer about the encryption module in solr-sandbox. It is in sandbox, not integrated (yet) in the Solr project, so there can be some road blocks. That said, I'll try to help.
1- Can you share the encryption-specific parts of your solrconfig.xml file? 2- Can you share the full stacktrace for the exception you mentioned? 3- How do you trigger the index encryption? Do you call the EncryptionRequestHandler? 4- Does it happen at the first (auto)commit, or some time later? Bruno
