Shi Xueyong, general manager of Software Division, Hangzhou, believes that my country is lagging behind the operating system and database, but domestic enterprises jointly struggle with foreign companies (see http://www.sunflow. com.cn/Article_show.asp?articleid=174), then how can domestic companies watch middleware in the fields?
In general, middleware can be classified: 1) Basic intermediates such as Sun JVM, Microsoft CLR, etc. 2) Universal middleware such as Iona Orbix, JBoss, etc. 3) The integrated middleware is mainly used with Workflow, EAI, etc. Technical development products such as Bea WebLogic Integration, etc.
At present, domestic companies have mainly developed integrated middleware, with the following uncomfortable middleware companies (products): 1) Sunflow2) of Jianda's Sunflow2) EOS3) Oriental Tong Series
