java - Error when using ProtocolLibrary PacketAdapter() -

-

i making craftbukkit plugin has message in player count list, hive-mc or omega realm. coding in ecplise , using protocollib v3.2.0 , craftbukkit 1.7.2 r0.3. new java , don't understand much. know imported.

so far, here imported methods, code, , error

methods:

import java.io.file; import java.io.ioexception; import java.util.arraylist; import java.util.arrays; import java.util.list;  import org.bukkit.plugin.java.javaplugin;  import com.comphenix.protocol.packettype; import com.comphenix.protocol.protocollibrary; import com.comphenix.protocol.events.listeneroptions; import com.comphenix.protocol.events.listenerpriority; import com.comphenix.protocol.events.packetadapter; import com.comphenix.protocol.wrappers.wrappedgameprofile;

code:

    private list<wrappedgameprofile> message = new arraylist<wrappedgameprofile>();  public void onenable() {     if(!new file(getdatafolder(),"reset.file").exists()){         try {             getconfig().set("pcmessage",                     arrays.aslist(new string[]{"first line", "second line"}));             new file(getdatafolder(),"reset.file").createnewfile();         } catch (ioexception e) {             e.printstacktrace();         }      }        saveconfig();      (string str : getconfig().getstringlist("pcmessage"))         message.add(new wrappedgameprofile("1", str));        protocollibrary     .getprotocolmanager()     .addpacketlistener(             new packetadapter(                     this,listenerpriority.normal,             arrays.aslist(new packettype[] {packettype.status.server.out_server_info}),             new listeneroptions[] { listeneroptions.async })); {      } }

error:

enter image description here

cannot instantiate type packetadapter

as see in javadocs packetadapeter, declared as:

public abstract class packetadapter implements packetlistener

abstract means class not full class, , must implemented full class or anonymous class, cannot instantiated. need find subclass of packetadapter, or make 1 yourself.

for more information, see java tutorial abstract methods , classes.

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
