[JDEV] Proper use of Perl Net::Jabber calls

[Yanming Xiao]

Rebbaj,

Sorry for my rush answer. After taking a look again at my code, 
I understand your problem this time. 

I found the following comment in my code.

#   this step is important --- to behavior as a regualr Jabber client.  
#
    %roster = $Connection->RosterGet();

I recalled the reason I wrote this comment here: "RosterGet()" is used to make a web client behaving like a regular Jabber client such as Exodus for Windows. Otherwise, 
you will not get a correct result by sending an IQ packet. That is what I found when I 
debugging my code. 

if you comment this line in the code segment I sent in my previous, the following 
IQ packet sending to the server would NOT give you a right result.

  Thanks Yanming.  I took a good long look at the code found at http://www.jabberstudio.org/cgi-bin/viewcvs.cgi/*checkout*/netjabber/examples/client.pl?rev=1.4&content-type=text/plain 

  What I still do not understand is why the $Connection->RosterGet(); call does not result in all of the roster entries being sent back from the server and hence triggering the sub InIQ routine.  If I manually enter the following XML "<iq type="get"><query xmlns="jabber:iq:roster"/></iq>, I get all the entries back. 

  The docs state "RosterGet() - sends an empty Net::Jabber::IQ::Roster tag to the server so the server will send the Roster to the client." 

  Any other ideas? 

  Regards,

    Rabbaj,

    It seems to me that you are using 2 different packages.  

    There is a function called "RosterGet()" in Net::Jabber::Client. 
    find the sample code in:

      Hello jabber people.

      I am hoping that someone can help me out with how the Perl Net::Jabber library should be used.  Note that I am also somewhat new to perl so if I get confused by some of the syntax, you will have to excuse me.  The examples in the Oreily book were rather helpful but I seem to be having problems in calling and receiving IQ information.

      Here is what I am trying to send and receive in XML:

      SENT:
      <iq id="jcl_9" type="get">
          <query xmlns="jabber:iq:roster"/>
      </iq>

      RECV:
      <iq from='rebbaj at jabber.org/Perl' id='jcl_9' type='result'>
        <query xmlns='jabber:iq:roster'>
          <item jid='rebbaj at jabber.com' name='rebbaj' subscription='both'/>
          <item jid='rebbaj2 at jabber.com' name='rebbaj2' subscription='both'/>
        </query>
      </iq>

      The code stub that I have written to do this is as follows.  I suspect that I have the flow a bit wrong and I am not using the optimal calls to parse the resulting returned roster data...  Any help would be appreciated....
