Hence, I am trying to segregate the routes in several different Route Builder classes and then connecting the routes where needed. For eg, all routes pertaining to sending emails go into a EmailRouteBuilder class and all routes dealing with a particular JMS Queue go into MyQueueRouteBuilder class. I suppose this should be alright since Camel doesnt not distinguish between classes and only looks for routes defininition. In addition, I am

I have seen a number of people claim they have Django 1.6 working. We'd like to get 1.6 or 1.7 running. I have searched here for instructions on how to set this up. No luck so far. Update: In our development machine we have Django 1.7 installed (both /user/local and on virtualenv). However, if we modify GAE yaml to use Django 1.7 we get the following error messages: google.appengine.api.yaml_errors.EventError: django version "1.7" is not

How do Bluetooth SDP and UUIDs work? (specifically for Android)

匿名 (未验证) 提交于 2019-12-03 02:20:02
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: My understanding is that the SDP is a list of UUIDs that other devices can fetch. According to this PDF from MIT, "A more general way to think of SDP is as an information database." Does this mean I can add multiple values to SDP? Since Android has BluetoothDevice.fetchUuidsWithSdp() , how do I set the UUIDs of a device? Also, what does each section of an UUID mean? UUIDs look like 00000000-0000-1000-8000-00805F9B34FB , but what information does this convey? 回答1: An UUID identifies a service that is available on a particular device. So if

Is there a way to get the “raw” events from the buttons? Because the music player only seems to offer an API to supply a bunch of MPMediaItem s. What if my app is for example a radio that needs to handle the buttons differently? 回答1: After a bit more searching I have found this related question that makes things

Why doesn't jsTree open_all() work for me?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Started playing around with jQuery and the jsTree plugin yesterday, and have it successfully loading the tree with an AJAX call to a servlet. Now, I would like to have the tree open all the nodes after loading so I added a success function to the ajax attribute. However, I cannot seem to get the open_all() method to work properly. I'm very new to working with jQuery so I'm guessing it's something simple that I'm doing wrong. Firebug isn't showing any errors which rules out the dumb error of mistyped method name. I checked the documentation
