Error in MXParser

i get that error while compiling xmpp

could someone help me in that error?

\src\org\mxp1\MXParser.java:35: org.mxp1.MXParser is not abstract and does not override abstract method setInput(java.io.InputStream) in org.xmlpull.v1.XmlPullParser

public class MXParser

i traced the error i found that the line

parser.setInput(connection.reader); in file PacketReader it calls SetInput( ) with a Reader not InputStream as the interface XMLPullParser.java . any CLUE to fix this parsing error!!!

thanks
