error: unable to download document : "collection/default"

Got the following error message when launched the Update Manager Client GUI:

Error: Unable to download document : "collection/default" Cannot connect to retrieve collection/default: Internal Server Error.

I have just installed Sun Update Manager Proxy server and Sun Update Manager Client software in two sun servers. I configured the client to get update from the Update Manager Proxy server. I haven't register the Proxy server yet.

I have verified that Update Manager Proxy server is up and running by browsing the url of the Update Manager Proxy server.

I wonder if the error is because the Proxy server has no updates yet or it is because it is not registered yet.

Furthermore: I also tried the following on the client:

# smpatch analyze

and got the following error message

Failure: Cannot connect to retrieve detectors: Internal Server Error.

A look in the /var/adm/messages shows the following:

Caused by: java.io.IOException: Server returned HTTP response code: 500 for URL: http://solaris0.sd.ny.frb.org:3816/solaris

The first thing to do is to register the proxy server. After that if there is still a problem please provide output of "smpatch get" and "smpatch analyze" from both client and server.
