[NNTP] Unable to list newsgroups with commons.net module

[tudstudent]

Hi all,

This is my first post on this forum, so I hope I am doing this post correctly. If not let me know.
This weekend I have picked up my hobby in programming. AFter doing some in VBA/VB/C# and C back to my basics Java....

But now I am running against a wall. I was building a NNTP tool. For this I use the commons.net package form apache:

org.apache.commons.net.*

To do some testing with this I grabbed the test programs. Some of them are running fine, but at the moment I want to use the function list newsgroups it is going nuts:

LIST ACTIVE alt.fan.*
215 Newsgroups in form "group high low flags".
org.apache.commons.net.MalformedServerReplyException:  000000000000000 000000000000000 y
	at org.apache.commons.net.nntp.NNTPClient.__readNewsgroupListing(NNTPClient.java:255)
	at org.apache.commons.net.nntp.NNTPClient.listNewsgroups(NNTPClient.java:949)
	at ExtendedNNTPOps.demo(ExtendedNNTPOps.java:70)
	at ExtendedNNTPOps.main(ExtendedNNTPOps.java:89)
	at Testing_NNTP.main(Testing_NNTP.java:21)

Code where it is failing on is specificly:

list = client.listNewsgroups();

May be someone knows this problem or knows what I am doing wrong. I have referenced the jar from apache in my project and logging in is no problem this is telling me that it should be working:

201 reader.xsnews.nl (frontend-F06-02) Server Ready - support@xsnews.nl
AUTHINFO USER ******
381 PASS required
AUTHINFO PASS *******
281 Ok
Authentication succeeded
GROUP alt.test
211 65330 4635 69964 alt.test
XOVER 4635-4735
224 data follows

Any help on this is appreciated.

Ps. Aditional question, is it possible to make the connection over ssl?
Ps1:

Small update. Got SSL to work, so this is fixed.

Only solution I am still looking for is why my newsgroups are not returned by Listnewsgroups.

Same here.

LIST
215 Newsgroups in form "group high low flags".
alt.binaries.boneless 4968906987 2256535552 y
org.apache.commons.net.MalformedServerReplyException: alt.binaries.boneless 4968906987 2256535552 y

	at org.apache.commons.net.nntp.NNTPClient.listNewsgroups(NNTPClient.java:930)
	at com.scary.Nntp.main(Nntp.java:44)

Please let me know if you find a solution to this. That's be great!
