I am writeing forum plugin of Jive Messenger , I am start socket to listen port(5533)

This is parse Message packet Error :

Socket connect Socket[addr=/10.1.16.32, port=1951, localport=5533]

org.xmlpull.v1.XmlPullParserException: start tag not allowed in epilog but got m

}

while (open) {

Element doc = reader.parseDocument().getRootElement(); // ERROR

First Send Of Client is OK ,but continuity send is Error ! Why ?

Thanks !

Hey zhuam,

I see that the client is sending \r\n between the XML packets. I guess that those characters are making the parser fail. Try modifying the client so that those characters are not sent.

Hey Gota,

I am already change source on XML packets, but not solve problem ,

This is Exception :

This is test source :

import java.io.BufferedWriter;

import java.io.IOException;

import java.io.OutputStreamWriter;

import java.net.Socket;

public class testForum {

public static void main(String[] args) {

String host = “10.1.16.32”;

int port = 5533;

Socket soc=null;

String strout=null;

try

{

soc=new Socket(host,port);

System.out.println(“Connecting to the Server”);

BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(soc.getOutputStream(), “UTF-8”));

for(int i=1 ; i";

writer.write(strout);

writer.flush();

}

}

catch(Exception e)

{

System.out.println(“error:”+e);

}

finally

{

try {

soc.close();

} catch (IOException e) {

e.printStackTrace();

}

System.exit(0);

}

}

}

try using a valid xml document as input,

wrap the

for(int i=1 ; i");

writer.flush();

and modify the parser on the server side so it skips the first tag, eg

private void readStream() throws Exception {

//wait for the first tag using the underlying XmlPullParser…

XmlPullParser xpp = reader.getXPPParser();

for (int eventType = xpp.getEventType(); eventType != XmlPullParser.START_TAG;) {

eventType = xpp.next();

}

open = true;

while (open) {

Element doc = reader.parseDocument().getRootElement();

if (doc == null) {

// Stop reading the stream since the client has sent an end of

// stream element and probably closed the connection.

open = false;

}

}

}

thanks for your bram !

I am already try using a valid xml document , add a Root Element , but is not a solve concatenation send message problem , I believe this problem should be also exist of Jive Messenger ,

I am current a solved method :

public String readStream(InputStream InStream) {

reader = new XPPPacketReader();

reader.setXPPFactory(factory);

try {

reader.getXPPParser().setInput(new InputStreamReader(InStream,CHARSET));

} catch (UnsupportedEncodingException e1) {

e1.printStackTrace();

} catch (XmlPullParserException e1) {

e1.printStackTrace();

}

Element doc = null;

try {

doc = reader.parseDocument().getRootElement();

} catch (DocumentException e1) {

e1.printStackTrace();

} catch (IOException e1) {

e1.printStackTrace();

} catch (XmlPullParserException e1) {

e1.printStackTrace();

}

if (doc == null) {

return “”;

}

…

ok, you’'re half way there

the trick is to “skip” the first element (the document root) and after the first element use the reader.parseDocument() method. then that method returns a document for each “sub element” of the root, so with a xml file like this :

end tag).

try it and when you put in a trace in thw while loop you should be able to echo the child elements of the root after they are send by the client.
