/chatservice/rest/hello

// servletWrapper

package com.chatservice.chat.plugin.service;

import com.chatservice.chat.plugin.ChatServiceApplication;

import com.sun.jersey.spi.container.servlet.ServletContainer;

public class JerseyServletWrapper extends ServletContainer {

private static final long serialVersionUID = 1L;

public JerseyServletWrapper() {

super(new ChatServiceApplication());

}

}

// Application

package com.chatservice.chat.plugin;

import java.util.HashSet;

import java.util.Set;

import javax.ws.rs.core.Application;

import com.chatservice.chat.plugin.service.HelloWorldResource;

public class ChatServiceApplication extends Application {

private HashSet<Class<?>> classes = new HashSet>();

private HashSet singletones = new HashSet();

public ChatServiceApplication() {

super();

singletones.add(new HelloWorldResource());

}

@Override

public Set<Class<?>> getClasses() {

return this.classes;

}

@Override

public Set getSingletons() {

return this.singletones;

}

}

// Plugin

package com.chatservice.chat.plugin;

import java.io.File;

import org.jivesoftware.admin.AuthCheckFilter;

import org.jivesoftware.openfire.container.PluginManager;

import org.jivesoftware.util.Log;

public class ChatPlugin implements Plugin {

@Override

public void destroyPlugin() {

AuthCheckFilter.removeExclude(“chatservice/rest/*”);

}

@Override

public void initializePlugin(PluginManager pluginManager, File pluginDirectory) {

Log.info(“Starting Chat Plugin”);

AuthCheckFilter.addExclude(“chatservice/rest/*”);

}

}
