Question About Tigase-server 8.3.1 and Smack 4.4.7

AckeMa · April 2, 2024, 2:47am

Hello again！

I am using tigase-server 8.3.1 as xmpp server, and smack 4.4.7 as xmpp client.

                    XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                            .setUsernameAndPassword("username", "password")
                            .setXmppDomain("my.own.com")
                            .setHost("my.own.com")
                            .enableDefaultDebugger()
                            .build();

                    AbstractXMPPConnection connection = new XMPPTCPConnection(config);
                    connection.connect();
                    Log.i("SDK", "after connect");
                    connection.login();
                    Log.i("SDK", "after login");

                    Message message = connection.getStanzaFactory()
                            .buildMessageStanza()
                            .to("anotheruser@my.own.com")
                            .setBody("Howdy! How are you?")
                            .build();
                    connection.sendStanza(message);

                    Log.i("SDK", "after send");

After this:

SENT (0): 
<iq id='AUJIG-1' type='set'>
  <bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
  </bind>
</iq>
RECV (0):

    <jid>
      username@my.own.com/1423222896-tigase-27
    </jid>
  </bind>
</iq>

I got Exception:

Is there anything wrong with my code?

I fixed this problem:

if I use “smack-xmlparser-stax-4.4.7.jar”

implementation files('libs/smack-xmlparser-stax-4.4.7.jar')

Smack failed to parse this mesage:

<iq xmlns="jabber:client" type="result" to="username@my.own.com/1423222896-tigase-48" id="K5P4X-1">

                                                                                                      </bind>
                                                                                                    </iq>

If I use

implementation files('libs/smack-xmlparser-xpp3-4.4.7.jar')

Smack works well.

But I donot know why.

This is curious. I can’t immediately spot what is going wrong. I’d expect your original code to work. @Flow any idea what’s going on here?

Flow · April 3, 2024, 8:11am

It appears that

github.com

igniterealtime/Smack/blob/4.4.7/smack-core/src/main/java/org/jivesoftware/smack/util/PacketParserUtils.java#L513


      
          public static IqData parseIqData(XmlPullParser parser) throws XmppStringprepException {
              final String id = parser.getAttributeValue("", "id");
              IqData iqData = StanzaBuilder.buildIqData(id);
          
              final Jid to = ParserUtils.getJidAttribute(parser, "to");
              iqData.to(to);
          
              final Jid from = ParserUtils.getJidAttribute(parser, "from");
              iqData.from(from);
          
              String typeString = parser.getAttributeValue("", "type");
              final IQ.Type type = IQ.Type.fromString(typeString);
              iqData.ofType(type);
          
              return iqData;
          }
          
          /**
           * Parses an IQ packet.
           *
           * @param parser the XML parser, positioned at the start of an IQ packet.

is returning null, but only if the stax parser is used (as per @AckeMA).

@AckeMA could you create a breakpoint at L513 and debug why the method (or the underlying stax) parser returns null?

that is not really how you should switch parser backends nor pull in part of the Smack library. First, ideally you would maven dependency specifications. Secondly, use SPI to select an xmlparser implementation.

Hello, I will post my code the day after tomorrow.

I try to build an Android APP with smack.
I use Android Studio and gradle to build my APP.

I build Smack 4.4.7 with jdk1.8 and Gradle 6.8.3 in gradle/wrapper.
I build my APP with jdk 17.0.7 and Gradle 8.2.2

This is my APP’s build.gradle:

This is my code in Activy.java:

        Logger logger = Logger.getLogger("org.jivesoftware.smack");

                try {
                    XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                            .setUsernameAndPassword("username", "onepasswd")
                            .setXmppDomain("tigase.mydomain.cn")
                            .setHost("tigase.mydomain.cn")
                            .enableDefaultDebugger()
                            .build();

                    AbstractXMPPConnection connection = new XMPPTCPConnection(config);
                    connection.connect();
                    connection.login();

                    Message message = connection.getStanzaFactory()
                            .buildMessageStanza()
                            .to("ackema@tigase.mydomain.cn")
                            .setBody("Howdy! How are you?")
                            .build();
                    connection.sendStanza(message);

                    Log.i("SDKTest", "after send");

                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }
