Just Use an Ajax Request and let your servlet provide some JSON in return to consume

        new Ext.Button({
            text:'click me',
            handler: function() {


Ext.Ajax.request({
                                url: 'urlToYourServlet',
                                success: function(a){
                                    var retObj = Ext.util.JSON.decode(a.responseText);
                                },
                                failure: function(f,a){
                                }
                            });
        });

i like use ajax because it work and not reface page but you use validate, you must to check form before use Ext.ajax.request().
