HTTPS call failing from NW2004s SP09

Hi,

When I make a call to an authentication service from a system on NW2004s SP09, I get the following error

GenericService::invoke()

java.lang.Exception: iaik.protocol.https.HttpsURLConnection incompatible with javax.net.ssl.HttpsURLConnection

This works fine with a NW2004s system on a SP12 system.

What is the main difference in the SSL setup between SP09 and SP12 of NW2004S.

Regards

Schunder
