I would like to put a XAdES-T signature on an XML file using xades4j. My application works if the timestamp provider is listening on an HTTP URI (e.g. http://tsa.starfieldtech.com/), but I get error messages (s. later) if the timestamp provider needs SSL connection (e.g. https://tsa.hiteles.gov.hu/ts).
How should I adjust my code? I have got an SSL certificate from the timestamp provider but I don't know how to use it...
Stacktrace with error details:

EDIT 1: After I have put
System.setProperty("javax.net.debug", "all");
into my code I get a lot of debug message ending like this:
%% Invalidated: [Session-1, TLS_RSA_WITH_AES_256_CBC_SHA]
main, SEND TLSv1 ALERT: fatal, description = certificate_unknown
main, WRITE: TLSv1 Alert, length = 2
[Raw write]: length = 7
0000: 15 03 01 00 02 02 2E .......
main, called closeSocket()

main, called close()
main, called closeInternal(true)
EDIT 2: I have managed to go further by putting the certificates into a truststore but I still have problems with the handshake. I seems to me my client cannot send the server an appropriate certificate:
*** ServerHelloDone
[read] MD5 and SHA1 hashes: len = 4
0000: 0E 00 00 00 ....
Warning: no suitable certificate found - continuing without client authentication
*** Certificate chain
<Empty>
***
...
