javax.net.ssl.SSLKeyException: FATAL Alert:BAD_CERTIFICATE

Hi People,

I working on BEA 8.1 and i have a problems to make a SSL call....
I get an exception (SSLKeyException)... 

I read in somewhere that to make this kind of call, i need to use a SSLAdapter
to get the connection, but this not work for me.

[b]Like some:[/b]

SSLAdapter adp =SSLAdapterFactory.getDefaultFactory().getSSLAdapter();
URLConnection urlCon = adp.openConnection(new URL(url));
//URLConnection urlCon = (new URL(url)).openConnection();
BufferedReader in = new BufferedReader(new
InputStreamReader(urlCon.getInputStream()));

Can anybody help me? Thanks..
Mauro

[b]The log trace:[/b]

unuseable certificate was received.
