Job of 3 big main trends sheds engine technology analysis and market to forecast
1. From " kongfu " speak of
The new new mankind of nowadays sees me, regular meeting thinks to falling is a dye-in-the-wood antediluvian, this not, " kongfu " such film I just look to the end of this year Feburary. Had looked nevertheless " kongfu " , what I think is certain more than average person: Slash all corners of the country of week star billow, when with him fatso eldest brother goes out to knock bamboo lever, why should be two ax drawn before bosom of his eldest brother? Seek a false backer! Install the talent that is ax side to won't be bullied.
This lets me think of a news year ago: Jbpm Joins Jboss And Becomes Jboss-jbpm. That is to say, jbpm looked for a backer Jboss, later need not oneself are outer roamed about.
Good, we turn into subject, the 3 big main trends that talk about here to say open source work to shed engine: Shark, osworkflow, jbpm.
The backer of Shark is Enhydra. What has Enhydra done? Much! Apply a server from J2ee, to O/r Mapping tool, to this the job sheds engine to wait a moment. Why does the abiding layer of Shark use DODS to come true? Because they are families,be.
The backer of Jbpm is Jboss. The abiding layer of Jbpm3 uses Hibernate3 to come true, because,also be this reason. The graph of Jbpm3 changes flow definition to had decided to embed in Jboss Eclipse IDE, everybody reads edition of Jboss Eclipse IDE Preview 1.5, we can have edited flow of a Jbpm3 to define a file with plug-in unit means.
The backer of Osworkflow is Opensymphony. I like this organization very much, it made a lot of good things. When development work sheds administrative system, I recommend the another thing that uses it: Webwork2. The job opening a source that the author manages sheds engine AgileFlow to be based on framework of Ww2 Spring Hibernate to come true namely.
Finish this paragraph when the word outside saying a problem: Now basically the job that servers of all J2EE application process have him sheds engine, the Enhydra that as above face mentions, jboss and the Websphere that did not mention and Weblogic, visible, learning the job to shed engine technology is very important really.
2. Buddha god palm
Light has backer is no good, is Zhou Xingxing joined ax to help still be hit by fiend flat first? Want to save oneself, still want to rely on Buddha god palm.
The flow definition language of Shark is XPDL, we know, two of XPDL the mainest ideas are Process and Activity. The Activity in XPDL is the concept that the activity in be based on UML1.x pursues. What the activity pursues inherent is comfortable build a model at working flow, its photograph is the bifurcate control that makes intercurrent line Cheng easily to a at state diagram the biggest advantage, cheng also can carry out these intercurrent lines at the same time; It still has an advantage is the idea that has lane, can control the job to shed the generation of the task in engine. The Buddha god palm of Shark is mobile graph.
