Domestic Android devices, can not stabilize the use of Google GCM (Google Cloud messageing) message push service. 1. Domestic Android devices, basically from the bottom of the operating system to remove the Google framework 2. Google servers are abroad, the most recent in Hong Kong, and other reasons, causing domestic mobile phone and Google server connectivity instability 3. Some enterprise customers also do not want to use public services, it is best to use their own intranet to push the se

Recently in a project to use the message push, after searching the internet for a while to find IBM's two MQTT libraries, respectively, Wmqtt.jar and Mqttv3.jar. This article is mainly for the use of Mqttva.jar library to explain.The first choice is to build the ACTIVEMQ server. ACTIVEMQ Server installation and dynamic line can be online Baidu or other engine search, the introduction is very complete.First, use ADT to establish the following worksThe

Description: MQTT is an instant Messaging protocol developed by IBM that is likely to be an important part of the Internet of things. The protocol supports all platforms, almost all connected items and external connections, and is used as a communication protocol for sensors and actuators (such as the Internet of homes via Twitter). Apache Apollo is a proxy server, which is developed on the basis of ACTIVEMQ, can support stomp, AMQP,

Brief introductionTsung is a stress testing tool that can test servers including HTTP, WebDAV, PostgreSQL, MySQL, LDAP, and Xmpp/jabber. For HTTP testing, Tsung supportsHTTP 1.0/1.1, which contains a proxy-mode session record, supports GET, POST and PUT, and DELETE methods, supports cookies and basic WWW authentication, and also supports SSL.How the Tsung Works(1) Each virtual user of Tsung is a lightweight process of Erlang. There is a big difference between this and LoadRunner.(2) The virtual

The advantage of the FAT client (c/S mode) application is that both the client and the server can handle the task, the client's requirements are higher, but can reduce the pressure of the server, which is used in the enterprise internal management system. Disadvantage is the system client software installation, maintenance difficulties, the database system can no
