[WHW1984]

使用jetty作为web容器在osgi中使用，但是启动的时候报

代码如下
try{
Server server = new Server();
Connector connector = new SelectChannelConnector();
connector.setPort(8081);
server.setConnectors(new Connector[]{connector});
Constraint constraint = new Constraint();
constraint.setName(Constraint.__BASIC_AUTH);;
constraint.setRoles(new String[]{"user","admin","moderator"});
constraint.setAuthenticate(true);
ConstraintMapping cm = new ConstraintMapping();
cm.setConstraint(constraint);
cm.setPathSpec("/*");
SecurityHandler sh = new SecurityHandler();
sh.setUserRealm(new HashUserRealm("MyRealm","/etc/realm.properties"));
sh.setConstraintMappings(new ConstraintMapping[]{cm});
WebAppContext webappcontext = new WebAppContext();
webappcontext.setContextPath("/com.jetty");
webappcontext.setWar("com.jetty.war");
webappcontext.addHandler(sh);
HandlerCollection handlers= new HandlerCollection();
handlers.setHandlers(new Handler[]{webappcontext, new DefaultHandler()});
server.setHandler(handlers);
server.start(); //启动报错
server.join();
}catch(Exception e){
e.printStackTrace();
}
