OK, made a copy of the java package, included a script to uninstall previous versions.
If I publish the original java update it installs fine, but my custom one does not.
looked in the cab file and all files included, I see this error in my UPdatesDeployment.log file in sccm logs folder on the client.
Failed to get update (Site_A63C7738-4EBF-4551-B9FF-7F9AADDAE6C9/SUM_aae6d2be-3457-488a-b843-26cf86644908) Article Id, error = 0x87d00215
Any thoughts ?
