Various features in the UI of the site were failing because a number of links to imported libraries etc. used the "http" protocol and the new server infrastructure will respect only those using the "https" protocol. I downloaded the entire site from the server and replaced the old files in the svn repository with the files on the server, then searched all the files for "http" and replaced instances that were actual links with "https" and left instances that were identifiers for namespaces alone. Uploaded those revised files using the JNLP client and it seems to be working.
