java - Why my gadget is not receiving data? -

-

i have application on appspot. on personal domain account.

i have put igoogle gadget on igoogle page of gmail account.

i sending ajax request gadget : 

          $(document).ready(function(){                 jquery.ajax({                     type: "get",                     url: "http://searcegadget2.appspot.com/requestservlet",                     success: function(msg){                         alert(msg);                         if(msg.search('tr') != -1){                             id = msg.split('</tr>').length - 1;                             //alert(id);                             $('#amounttable').append(msg);                             difference();                         }else if(msg.search('form') != -1){                             $('#gadget').css('display', 'none');                             document.write(msg);                         }else if(msg.search('http') != -1){                             document.location = msg;                             $('#amounttable').append(msg);                         }                      },error: function(xmlhttprequest, textstatus, errorthrown){                         alert("xmlhttprequest: " + xmlhttprequest.responsetext);                         alert("textstatus : " + textstatus.responsetext);                         alert("errorthrown : "+ errorthrown);                     }                 });             });

there nothing shown in xmlhttprequest & errorthrown alerts. but, there "error" shown in textstatus !

now, link "http://searcegadget2.appspot.com/requestservlet" shown in red , when open "http://searcegadget2.appspot.com/requestservlet" inspect element in mozilla, returns me required data ! how attach gadget ?

my request servlet in java. reference : jquery.ajax()

also, have tested web application. working !

without seeing error message or , error code it's hard tell issue is, post, think it's cross-domain scripting issue. can't xmlhttprequest different domain. (e.g. gmail.com cannot xmlhttprequest searcegadget2.appspot.com without throwing error).

try add access-control-allow-origin header response of controller handles requestservlet endpoint.

for more information of access-control-allow-origin header, see thread:

access-control-allow-origin multiple origin domains?

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
